Product details
Overview
CY91F575BPMC-GSE2 from Infineon Technologies (formerly Cypress) is a 32-bit automotive-grade microcontroller featuring the FR81S CPU core, 512 KB + 64 KB program flash, 40 KB main RAM + 8 KB backup RAM, and integrated CAN 2.0B (3 channels), LIN-UART (6 channels), and 40-channel 10-bit ADC. It operates at up to 80 MHz with 5 V I/O tolerance and targets engine control units and body electronics.
For engineers reviewing the CY91F575BPMC-GSE2 datasheet, CY91F575BPMC-GSE2 pinout, CY91F575BPMC-GSE2 application, or CY91F575BPMC-GSE2 equivalent, key selection criteria include its LQFP-144 package, 80 MHz FR81S RISC core, dual-clock supervision, hardware MPU, IEEE 754 FPU, and automotive-qualified low-power modes (Stop/Watch/Sub RUN).
Technical Context
The CY91F575BPMC-GSE2 implements a Harvard-architecture FR81S core with 5-stage pipeline, 16 general-purpose 32-bit registers, and 16-bit fixed-length instructions executing at 1 instruction/cycle. It integrates a PLL clock multiplier (1×–20×) enabling 80 MHz operation from a 4 MHz crystal, plus sub-oscillator support (32 kHz) for RTC and clock supervision.
Peripheral integration includes three C-CAN controllers (up to 1 Mbps), six LIN-UART channels compliant with LIN 2.1, four multi-protocol serial interfaces (UART/CSIO/LIN-UART/I²C), and a 16-bit PPG timer subsystem with 24 channels. Memory protection (MPU) defines eight configurable regions with privilege/user mode access control.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 32-bit automotive microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| RH850/F1L | 400 MHz dual-core, 2 MB flash, no integrated LIN-UART; requires external LIN transceivers | Higher performance for ADAS preprocessing; lacks on-die LIN PHY and stepping motor controller | Select when >200 DMIPS needed and external transceivers acceptable |

FAQ
What is the maximum operating junction temperature for CY91F575BPMC-GSE2?
The absolute maximum junction temperature is +150°C, with recommended continuous operation limited to +125°C ambient under specified thermal conditions (JEDEC JESD51-2 compliant PCB layout). Thermal derating applies above 105°C ambient; full electrical specifications are guaranteed from −40°C to +125°C.
Does CY91F575BPMC-GSE2 support flash programming during runtime?
Yes, it supports Read-While-Write (RWW) operation on program flash and dedicated WorkFlash memory. The 64 KB WorkFlash allows data logging and parameter storage with background erase/write while application code executes from main flash, enabling robust firmware updates and calibration retention.
How is clock failure detection implemented in this MCU?
Clock failure detection uses independent oscillation monitors for both the 4 MHz main crystal and 32 kHz sub-crystal. Upon detection of stoppage or frequency deviation beyond ±20%, the hardware automatically switches to the internal CR oscillator and asserts NMI or resets the system based on configuration-ensuring fail-safe behavior per ISO 26262 requirements.
Can the PPG timers generate complementary PWM outputs with programmable dead time?
No, the 24-channel PPG subsystem does not include hardware dead-time insertion. However, it supports synchronized PWM output pairs via shared reload counters and phase-shifted start triggers, enabling basic 3-phase motor control; dead time must be implemented in software or with external gate drivers.
