This application note provides a few example circuits, design guidelines, and PSoC®3 based sample code snippets to help users understand and design with Cypress I²C nvSRAM.

An "I²C nvRAM" component library is also created using Cypress PSoC®3 device as a reference design project and attached to this Application Note. The PSoC®3 component library configures Cypress PSoC®3 device as a standard I²C master controller and also provides the list of APIs which can directly be called in an application firmware to access the I²C nvSRAM functions.

• Three modes of operation of the FX1/FX2LP
• Endpoint Configuration and Multiple Buffering
• Three Domains that form the basic component of the FIFO architecture
• Arming and committing endpoint buffers
• Endpoint operation in manual vs. auto mode

AN75705 helps you get started with FX3. It highlights the key uses, applications, and features of FX3. A comprehensive list of design resources available from Cypress is also provided. This application note walks you through the steps to get started with USB transfers using the FX3 development kit (DVK) and software development kit (SDK).

Video on EZ-USB FX3 Architecture Overview - click below

The I²C nvSRAM offers all four standard I²C-bus modes (Standard-mode - 100KHz, Fast-mode - 400 KHz, Fast-mode plus - 1 MHz, and High-speed mode - 3.4 MHz) through a single solution. As a result, Cypress has standardized someof the I/O specifications across all modes to offer consistent I/O behavior across the modes. This standardization causes some ofits I/O specifications slightly differ than NXP I²C standard. This application note highlights the I²C nvSRAM spec differences from the standard NXP I²C-bus specification. 

PRoC-CS is a 2.4-GHz RF solution integrated with Cypress’ capacitive touch sensing 8-bit MCU. The PRoC-CS is a complete solution featuring 32-KB flash, with support for CapSense button, slider, proximity sensors, and a GFSK radio modem which can support data rate up to 1 Mbps.

Introduction

Temperature measurements typically use one of four sensors: thermocouple, thermistor, diode, and resistance temperature detector (RTD). The primary criteria for choosing a sensor are cost, accuracy, and temperature range. Although they are more expensive than other sensor types, RTDs have the best temperature accuracy. Calibrated platinum RTDs can achieve accuracy of >0.02 °C in the -200 °C to 850 °C range.

Cypress’s PSoC microcontrollers are easy-to-use, flexible, and have a cost-effective mix of reprogrammable analog and digital resources. These features provide many  opportunities for creative designs, one of which is programming the PSoC serially by an on-board host processor. This method is used to install or update firmware in-field or even completely reprogram the PSoC for a different function.

This document helps you to select the proper tool for CapSense sensor data viewing and logging. The two supported communication interfaces are I2C and UART. You should be familiar with CapSense sensing technology before you read this document.

The any-signal-to-any-pin routing available with PSoC 3 and PSoC 5LP GPIOs helps to optimize PCB layout, shorten design time, and allow for a large degree of solder-less rework. However, with this freedom comes a steeper learning curve than with a traditional microcontroller. This application note introduces you to PSoC 3 and PSoC 5LP GPIO basics and demonstrates techniques for their effective use in a design.

The nvSRAM architecture uses a one-to-one pairing of a nonvolatile bit and a fast SRAM bit in each memory cell. During normal operation, the IC behaves exactly as a standard fast asynchronous SRAM and is easy to interface with the microprocessor or microcontroller. When IC power is disrupted or lost, the event is detected and all the SRAM bits are saved into the nonvolatile part (within 8 ms) using the stored energy in a small capacitor (VCAP). This operation is called AutoStore and is described in more detail in the next section. When power is restored, data is automatically recalled from the nonvolatile part to SRAM on power restore and this operation is called Power Up RECALL (Hardware RECALL).
 

Cypress CY14E256LA is a 5 V, 256 Kbit (32 K x 8) nvSRAM in 0.13 u technology. It is a pin to pin functional equivalent of CY14E256L/STK14C88 (0.8 u) and is a drop in replacement in most AutoStore applications. However, in an existing AutoStore inhibit application, the circuit would require change in routing of power to the VCC pin and a firmware change to disable AutoStore.

This application note highlights the differences between the CY14E256L/STK14C88 and the CY14E256LA and the parameters of significance that must be considered while migrating.

Computing and communication systems are complex and comprise multiple subsystems. Each subsystem can have its own voltage domain, which is also known as a power rail. Each power rail needs to be powered up and monitored individually. This creates a need for power management. Because this activity is a health indicator of the system, it cannot be incorporated in any of the subsystems. For this reason, a dedicated chip is used.

Power management consists of the following parts:

• accurate and reliable voltage sequencing
• rapid power rail fault detection
• voltage and current monitoring of power rails to optimize power consumption
• real-time trimming for closed-loop control of power converters (voltage regulators)
• in-system margining
• fault/event logging in EEPROM
• communication with the host controller using I2C, SMBus, or PMBus

Cypress offers the highest performance and most reliable nonvolatile RAM products available with its nvSRAM product line. The nvSRAM technology combines the performance characteristics of a high-speed SRAM with that of a nonvolatile memory. A similar nonvolatile solution is the Magnetoresistive RAM (MRAM) from Everspin in which magnetic polarization is used to store information. This application note discusses designing applications hardware with the option to use either MRAM or nvSRAM on the same socket without any hardware redesign.
 

To get introduced to basics of PSoC 3 and PSoC 5LP Bootloader please refer  AN73854 - PSoC® 3 and PSoC 5LP - Introduction to Bootloaders. If you intend to learn how to develop I2C Bootloader for PSoC 3 and PSoC 5LP,  AN60317 - PSoC® 3/PSoC 5LP I2C Bootloader  should get you going. 

Since the projects involve the use of USB component, in case of PSoC 5LP it is mandatory to use an external 24 MHz crystal.

The Bootloader GUI provided with this App Note has been tested to work on full-fledged Windows operating system only.
The GUI is not tested and not guaranteed to work on Virtual machines.

In addition, FX3 provides interfaces to connect to serial peripherals, such as UART, SPI, I2C, and I2S.

FX3 allows you to add SuperSpeed capability to any FPGA-based design. In most applications, FPGA acts as a master and the GPIF II operates in a synchronous Slave FIFO interface.

Several common debugging techniques are described to help you solve common problems, such as stack overflow and memory corruption. A troubleshooting guide is included. 

Introduction

The purpose of this application note is to introduce the hardware and software debugger elements available in PSoC 1 and to describe several common debugging techniques.

The primary hardware elements of the debugging system are an In-Circuit-Emulator (ICE) and a debug pod with an on chip debugger (OCD) enabled PSoC 1 device. Those elements, and instructions on configuring and using them, are described in the Debugging Hardware portion of this application note.

Introduction

The DMA controller (DMAC) in PSoC 3 and PSoC 5LP can transfer data from a source to a destination with no CPU intervention. This allows the CPU to handle other tasks while the DMA does data transfers, thereby achieving a „multiprocessing‟ environment.

The PSoC DMA Controller (DMAC) is highly flexible – it can seamlessly transfer data between memory and on chip peripherals including ADCs, DACs, Filter, USB, UART, and SPI. There are 24 independent DMA channels.

Cypress’s Radiation Hardened 72Mbit QDR®II+ is a source synchronous pipelined Static RAM equipped with the 1.8-V QDRII+ architecture with RadStop® technology. The QDRII+ architecture has separate data inputs and data outputs along with a common multiplexed address port. To maximize data throughput, both read and write ports are equipped with DDR interfaces which transfer data on both rising and falling edges of the clock signal. The result is that two/four bus widths of data are transferred during each clock period for Burst 2/Burst 4 configurations.
