MB91580S | Cypress Semiconductor

MB91580S

Based on Cypress' proprietary high performance FR81S core, these automotive MCUs offer high computing performance combined  with a rich peripheral feature set which make them highly suitable for vehicle motor control and DC/DC conversion applications. Embedded Resolver to Digital Converter (RDC) provide superior motor controllability at minimum communication overhead that is suitable for EV or HV, and EPS applications.

All members of the MB91580 series are based on Cypress' Flash Memory technology offering program storage as well as a separate  Work Flash as E2PROM emulation memory.

High Performance

A proprietary 32-bit RISC CPU core features an operating speed up to 128 MHz, with 160 DMIPS performance. This high-level RISC core, which is based on a Harvard architecture with separated instruction and data bus, is optimized for applications that require high-speed control. An optimized instruction set assures low-code-size densities and high execution speeds.

The latest generation in the FR81 features an improved CPU core with an enhanced instruction pipeline for reduced branch penalty. The newest members of the family (the MB91520, MB91570, MB91580 and MB91590 MCU-series) also include a single, precision Floating Point Unit (FPU), providing the extra computing power that complex control algorithms require.

Highly Reliable Flash Memory

Memory densities range from 384KB to 2MB Flash. The highly reliable, high-speed Flash memory has an endurance of 100,000 write/erase cycles with up to 20 years of data retention.

Communications Interfaces

The devices include Controller Area Network (CAN), FlexRay and Local Interconnect Network (LIN) interfaces. These interfaces, combined with the large, on-chip memory capacity, enable efficient data collection, processing and distribution. Many devices offer an external bus interface that can e.g. be connected to Cypress' standalone FlexRay controller or to the latest generation of graphics controllers to build full-featured dashboards, driver-information and advanced driver-assistance systems.

Motor Control for EV and HV Automobiles

The new MB91580 series enables optimal, high-speed, 3-phase inverter motor control in electric (EV) and hybrid vehicles (HV). This system delivers real-time control for EV and HV motors with fast and efficient loopback operation and the best torque control possible. This level of integration enables system designers to achieve higher performance while significantly reducing costs.

The latest generation in the FR81 features an improved CPU core with an enhanced instruction pipeline for reduced branch penalty. The newest members of the family (the MB91520, MB91570, MB91580 and MB91590 MCU-series) also include a single, precision Floating Point Unit (FPU), providing the extra computing power that complex control algorithms require.

Development Tools

Cypress and its external partners offer a full set of development tools such as starter kits, hardware and software debuggers, and third-party-supported automotive operating systems like AUTOSAR and OSEK.

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.

We introduce the sample programs of FR81S Family. Please use it for the confirmation of the operation specification and the use of our microcontroller etc.
