FM3 MB9Bx20J-Series ARM® Cortex®-M3 Microcontroller (MCU) Family | Cypress Semiconductor

FM3 MB9Bx20J-Series ARM® Cortex®-M3 Microcontroller (MCU) Family

The FM3 family of 32-bit general-purpose MCUs is based on the ARM Cortex®-M3 CPU, which provides a scalable platform for many consumer and industrial applications. Popular applications range from motor control, factory automation, white goods and power tools to medical devices, major home appliances, digital consumer devices and office automation equipment. As a part of the Cypress FM3 family of ARM Cortex®-M3 based microcontrollers, the MB9Bx20J-Series is a general purpose family with low power modes, integrated flash memory, SRAM and rich peripheral functions like timers, ADCs, DACs and communication interfaces.

Application Notes

 

Peripheral Driver Library

FM MCU Peripheral Driver Library (PDL)

The FM MCU Peripheral Driver Library (PDL) simplifies software development for the FM0+, FM3, and FM4 MCU families. The PDL reduces the need to understand register usage and bit structures, thus easing software development for the extensive set of peripherals in the FM families. You configure the library for the particular device, and then use API calls to initialize and use a peripheral. Using the PDL makes it easier to port code from one family to the other, because the same code supports all FM families.

The Sample Programs ("Programs") are offered for use in developing systems for Cypress microcontrollers.

The Programs will be useful in the following situations:

  • I need a simple sample program, as I am going to develop software. The sequence of resource access, among others, can be confirmed using these Programs.
  • I would like to examine, before development, whether each resource will operate as expected.
    The Programs support several specifications, even for the operation of one resource.
  • If resources do not operate properly on my system, I would like software for which confirmation of operation has been completed. Cypress has confirmed the actual operation of the Programs on each of its microcontrollers, so you will be able to compare your program with the Program.

For the FM portfolios, code examples are provided with the Peripheral Driver Library (PDL). Download and install the PDL, and look in the examples folder.
