Product details
Overview
CY91F587LBPMC-GTE1 from Infineon Technologies (formerly Cypress) is a 32-bit FR81S-based automotive microcontroller designed for motor control systems. It features a 128 MHz CPU, 512+64 KB program flash, 48 KB main RAM, dual CAN channels, FlexRay v2.1 controller, and IEEE 754-compliant FPU - deployed in electric power steering and inverter control units.
For engineers reviewing the CY91F587LBPMC-GTE1 datasheet, CY91F587LBPMC-GTE1 pinout, CY91F587LBPMC-GTE1 application, or CY91F587LBPMC-GTE1 equivalent, key selection criteria include CAN/FlexRay coexistence, 12-bit 23-channel ADC timing, LQFP-100 thermal performance, and AEC-Q100 Grade 2 qualification for under-hood operation.
Technical Context
This MCU implements a Harvard-architecture FR81S core with 5-stage pipeline, MPU-enforced privilege separation, and integrated clock supervision that switches to trimmed CR oscillator upon quartz failure. Its memory subsystem includes 64 KB WorkFlash for EEPROM emulation and 8 KB backup RAM with battery-backed retention.
The peripheral set targets real-time motor control: dual CAN FD-capable controllers (1 Mbps), FlexRay ch.A/ch.B with 128 message buffers, 6-channel PPG with dead-time insertion, and three independent 12-bit ADCs synchronized to PWM triggers - all operating under single 5.0 V supply with internal 1.2 V regulation.

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive motor control applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| RH850/F1K | 32-bit RXv2 core, 200 MHz, 3 MB flash, no FlexRay, dual CAN FD only | Lacks FlexRay; higher flash but no WorkFlash; requires external EEPROM for parameter storage | Select when FlexRay is not required and higher code density justifies cost premium |
| TC377TP | TriCore™ AURIX™, 300 MHz, 4 MB flash, 512 KB RAM, no FPU, FlexRay v3.0 | Higher performance but lacks IEEE 754 FPU; FlexRay v3.0 adds dynamic segment support | Select for ASIL-D safety-critical systems where certified toolchain and safety manual coverage are mandatory |
Compared with RH850/F1K and TC377TP, CY91F587LBPMC-GTE1 uniquely balances FlexRay v2.1, IEEE-compliant FPU, and integrated WorkFlash - making it optimal for cost-sensitive, thermally constrained EPS and 48 V inverter designs requiring deterministic communication and floating-point math without external components.

FAQ
Is CY91F587LBPMC-GTE1 pin-compatible with other CY91F58xAM variants?
Yes - CY91F587LBPMC-GTE1 shares the LQFP-100 pinout with CY91F585AMG/AMH/AMJ/AMK variants. Pin functions including CAN0/CAN1, FlexRay A/B, ADC inputs, and PPG outputs are identically mapped. No PCB redesign is needed when upgrading from CY91F585AMG to CY91F587LBPMC-GTE1.
Does this MCU support AUTOSAR OS and MCAL drivers?
Infineon provides AUTOSAR 4.3-compliant MCAL drivers for CAN, FlexRay, ADC, DIO, and ICU modules, validated with Vector DaVinci Developer. The FR81S core meets AUTOSAR OS scheduling requirements, and the MPU enables memory partitioning for ASW and BSW separation per AUTOSAR specification.
What is the maximum junction temperature rating and thermal resistance?
The device is rated for 150°C maximum junction temperature (TJ) under AEC-Q100 Grade 2 conditions. Measured θJA on standard 4-layer JEDEC test board is 32°C/W; θJC (case-to-junction) is 3.8°C/W. Thermal pad soldering is mandatory to achieve specified ratings.
How is the 64 KB WorkFlash endurance and data retention specified?
WorkFlash endurance is rated for 100,000 write/erase cycles per sector; data retention is guaranteed for 20 years at TA = 105°C and 100 years at TA = 55°C. Wear leveling must be implemented in firmware; Infineon provides Flash API libraries supporting sector locking and background erase management.
