Product details
Overview
CY91F585AMGPMC-GTE1 from Infineon Technologies (formerly Cypress) is a 32-bit FR81S RISC microcontroller designed for automotive motor control systems. It features a 128MHz CPU core, 512+64 KB program flash, 48 KB main RAM, 8 KB backup RAM, integrated CAN 2.0B (2 channels), FlexRay v2.1 (1 unit), and LIN 2.1 (4 serial channels). It operates on a single 5V supply with internal 1.2V regulation and targets electric power steering and inverter control units.
For engineers reviewing the CY91F585AMGPMC-GTE1 datasheet, CY91F585AMGPMC-GTE1 pinout, CY91F585AMGPMC-GTE1 application, or CY91F585AMGPMC-GTE1 equivalent, key selection criteria include its dual CAN/FlexRay coexistence, 12-bit ADC (23 channels @ 1 µs), IEEE754 FPU, MPU-protected memory space, and LQFP-100 package with I/O relocation support.
Technical Context
This MCU implements the FR81S 32-bit RISC core with 5-stage pipeline, Harvard architecture, and instruction-level compatibility with the FR family. It integrates a PLL clock multiplication system (up to 32×), CR oscillator with trimming, and dual-clock supervision (main quartz + CR fallback).
The peripheral set is optimized for real-time motor control: two independent CAN controllers (1 Mbps), one FlexRay controller (128 message buffers, 8 KB message RAM), four multi-function serial interfaces (UART/CSIO/LIN/I²C), and analog subsystems including 3×12-bit ADCs and a 10-bit DAC.

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| RH850/F1K | 32-bit RXv2 core, 200 MHz max, 2 MB flash, no integrated FlexRay | Targets higher-end chassis control; requires external FlexRay PHY | Choose when >1 MB flash or higher CPU performance is required, and FlexRay is optional |

FAQ
What is the maximum operating temperature range for CY91F585AMGPMC-GTE1?
The device is qualified for automotive grade AEC-Q100 Grade 2 operation, supporting ambient temperatures from −40 °C to +105 °C. This rating applies to the full LQFP-100 package variant and is validated per JEDEC JESD22-A104 reliability testing standards.
Does CY91F585AMGPMC-GTE1 support JTAG debugging?
No - it uses Cypress/Infineon's proprietary On-Chip Debug (OCD) interface via SWD (Serial Wire Debug) pins. The OCD unit supports full breakpoint, watchpoint, and real-time trace capabilities compatible with Infineon's DAVE™ IDE and third-party tools like Lauterbach TRACE32.
Can the built-in 10-bit DAC drive a load directly?
The DAC output (DA0) has limited drive strength (±1 mA typical) and is intended for reference voltage generation or low-current biasing. Driving external loads >100 µA requires an external op-amp buffer; the datasheet specifies no rail-to-rail output swing or short-circuit protection.
Is the 64 KB WorkFlash memory endurance rated for field updates?
Yes - the WorkFlash is specified for ≥100,000 erase/write cycles at junction temperature ≤125 °C, with data retention ≥20 years at 105 °C. It supports sector-wise erase and byte-wise programming, enabling robust OTA firmware patching in automotive ECUs.
