Product details
Overview
CY91F524KWCPMC-GSE2 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, IEEE 754-compliant FPU, and triple CAN 2.0B controllers supporting up to 1 Mbps. It operates at 80 MHz (12.5 ns instruction cycle), features hardware memory protection (MPU), ECC on flash/RAM, and is qualified for -40°C to +125°C operation in engine control and body electronics.
For engineers reviewing the CY91F524KWCPMC-GSE2 datasheet, CY91F524KWCPMC-GSE2 pinout, CY91F524KWCPMC-GSE2 application, or CY91F524KWCPMC-GSE2 equivalent, key selection criteria include CAN channel count, RTC with subclock calibration, 12-bit ADC (48-channel total), LIN 2.1 support, and LQFP-144 package compatibility with automotive PCB layout constraints.
Technical Context
The CY91F524KWCPMC-GSE2 implements the FR81S 32-bit RISC core with 5-stage pipeline, Harvard architecture, and instruction-level multiplier (3-cycle 16-bit, 5-cycle 32-bit signed multiply). It integrates dual 12-bit ADC units (32+16 channels), two 8-bit DACs, and three independent CAN controllers-each with configurable message buffers (128/64 per channel).
Its clock system combines main oscillator (4–16 MHz), 32 kHz sub-oscillator with RTC calibration, 100 kHz CR oscillator, and SSCG-based PLL (1×–20× multiplication). Power management includes Sleep/Stop/Watch/Sub RUN modes, hardware/software watchdogs, and dual LVD monitoring (external 2.8 V ±8%, internal).

FAQ
What is the maximum operating frequency and instruction cycle time of the CY91F524KWCPMC-GSE2?
The CY91F524KWCPMC-GSE2 operates at a maximum system clock frequency of 80 MHz, achieving a minimum instruction execution time of 12.5 ns. This is attained using the on-chip PLL with 4.0 MHz crystal input multiplied 20×, and is confirmed in the electrical characteristics table (Section 11) of datasheet 002-04662 Rev. *I.
Does the CY91F524KWCPMC-GSE2 support CAN FD or only classical CAN 2.0B?
The CY91F524KWCPMC-GSE2 supports only CAN 2.0B protocol at up to 1 Mbps per channel. It does not implement CAN FD features such as flexible data-rate or extended data length. Its three CAN controllers are fully compatible with legacy automotive networks but lack FD arbitration and payload enhancements.
What are the memory protection and functional safety features included?
The device includes a hardware Memory Protection Unit (MPU) with eight configurable regions, ECC on both program flash and RAM, dual independent LVD monitors, hardware and software watchdog timers, and TPU (Timing Protection Unit) for runtime timing validation-all documented in Sections 7 and 11 of the datasheet for ASIL-B alignment.
Is the CY91F524KWCPMC-GSE2 pin-compatible with other CY91520 series variants?
Yes, the CY91F524KWCPMC-GSE2 in LQFP-144 is pin-compatible with other CY91F52x series members sharing the same package variant (e.g., CY91F523KWCPMC-GSE2, CY91F525KWCPMC-GSE2), differing only in flash/RAM capacity and peripheral enablement-verified in the "Product Lineup Comparison" tables (pages 5–9) of the datasheet.
