Product details
Overview
CY91F524BSCPMC1-GSE1 from Infineon Technologies (formerly Cypress) is a 32-bit FR81S automotive microcontroller with 512 KB + 64 KB program flash, 64 KB main RAM + 8 KB backup RAM, 80 MHz max CPU frequency, IEEE 754-compliant FPU, and integrated CAN 2.0B controllers (3 channels, up to 1 Mbps). It operates across –40 °C to +125 °C and supports sub-oscillator-based RTC calibration for engine control unit timing integrity.
For engineers reviewing the CY91F524BSCPMC1-GSE1 datasheet, CY91F524BSCPMC1-GSE1 pinout, CY91F524BSCPMC1-GSE1 application, or CY91F524BSCPMC1-GSE1 equivalent, key selection criteria include its dual-voltage LVD reset (2.8 V ±8%), ECC-protected Flash/RAM, 12-bit × 48-channel ADC with 1.4 μs conversion, LIN 2.1 support, and I/O relocation capability for ECU board layout flexibility.
Technical Context
The CY91F524BSCPMC1-GSE1 implements the FR81S 32-bit RISC core with 5-stage pipeline, Harvard architecture, and instruction compatibility with the FR family. It integrates an on-chip PLL supporting 4–16 MHz crystal input with multiplication up to 20×, enabling stable 80 MHz operation while maintaining 12.5 ns minimum instruction execution time.
Peripheral integration includes three independent CAN controllers (128/64-message buffers), twelve multi-function serial interfaces (UART/CSIO/LIN/I²C), a 16-bit × 48-channel PPG for LED and motor control, and hardware CRC generation. All memory blocks feature ECC, and the MPU enforces eight protection areas with privilege/user mode access control.

FAQ
What is the maximum operating frequency and associated voltage range for CY91F524BSCPMC1-GSE1?
The CY91F524BSCPMC1-GSE1 achieves a maximum CPU frequency of 80 MHz at 5.0 V supply, with guaranteed operation across 2.7 V to 5.5 V. At 2.7 V, maximum frequency is reduced to 40 MHz per electrical characteristics table (Section 11, Page 133 of DS002-04662 Rev. *I). The on-chip PLL supports multiplication of 4–16 MHz crystal inputs to reach full speed.
Does CY91F524BSCPMC1-GSE1 support LIN 2.1 protocol in hardware?
Yes, CY91F524BSCPMC1-GSE1 includes dedicated LIN hardware assist in its multi-function serial interface (MFS) blocks. It supports LIN 2.1 master and slave operation, including synch break generation/detection, synch delimiter generation, framing error detection, and DMA-supported transfer-without CPU intervention for protocol timing-critical tasks.
How is flash memory protected against corruption during power transitions?
CY91F524BSCPMC1-GSE1 employs ECC (Error Correction Code) on both program flash and WorkFlash, detecting and correcting single-bit errors in real time. Combined with hardware watchdog timers (both hardware and software variants), low-voltage detection reset (2.8 V ±8%), and power-on reset circuitry, it ensures flash integrity during brown-out, startup, and shutdown sequences.
What package variant corresponds to the suffix "PMC1" in CY91F524BSCPMC1-GSE1?
The "PMC1" suffix denotes the 144-pin LQFP package (Infineon package code LQH144), with 0.5 mm pitch, 20 mm × 20 mm body size, and lead-free/RoHS-compliant finish. This matches the "CY91F524D" product lineup entry in the datasheet's Ordering Information section (Page 210), confirming mechanical and thermal specifications per JEDEC MS-026.
