It operates at up to 80 MHz using internal PLL multiplication and supports -40°C to +125°C operation for engine control units and body electronics.
For engineers reviewing the CY91F522KSCPMC-GSE2 datasheet, CY91F522KSCPMC-GSE2 pinout, CY91F522KSCPMC-GSE2 application, or CY91F522KSCPMC-GSE2 equivalent, key selection criteria include its 120-pin LQFP package, dual-voltage 5 V/1.2 V supply architecture, hardware watchdog, memory protection unit (MPU), and LIN 2.1 + I²C + CSIO peripheral integration.
Technical Context
The CY91F522KSCPMC-GSE2 implements the FR81S 32-bit RISC core with 5-stage pipeline, Harvard architecture, and instruction compatibility with the broader FR family. It integrates a clock supervisor with sub-oscillator monitoring, CR oscillator fallback, and real-time clock calibration via prescaler adjustment.
Peripheral subsystems include three independent CAN controllers (128/64-message buffers per channel), 12 multi-function serial interfaces supporting UART/LIN/CSIO/I²C, and a 16-bit PPG timer subsystem with LED drive capability on channels 11–14. All peripherals support DMA transfer with up to 16 concurrent channels.
