Product details
Overview
CY90F543GSPMCR-GE1 from Cypress Semiconductor is a 16-bit F2MC-16LX microcontroller with dual FULL-CAN interfaces (CAN 2.0A/B), 128 KB Flash ROM, 6 KB RAM, and 81 general-purpose I/O ports. It features an on-chip PLL supporting 16 MHz system clock (62.5 ns min instruction time), 8/10-bit 8-channel ADC (26.3 µs conversion), and integrated peripherals including UART0/UART1, 16-bit timers, PPG, ICU/OCU, and external bus interface - deployed in automotive body control modules requiring real-time CAN communication and deterministic interrupt handling.
For engineers reviewing the CY90F543GSPMCR-GE1 datasheet, CY90F543GSPMCR-GE1 pinout, CY90F543GSPMCR-GE1 application, or CY90F543GSPMCR-GE1 equivalent, key selection criteria include dual-CAN channel support, Flash memory programmability with block protection, 32 kHz sub-clock for low-power modes, and QFP-100 package compatibility with industrial-grade temperature range (−40 °C to +105 °C).
Technical Context
The CY90F543GSPMCR-GE1 implements the proprietary F2MC-16LX CPU core with 23 addressing modes, 32-bit accumulator, and enhanced C-language support via system stack pointer and barrel shift instructions. Its dual FULL-CAN controllers each support up to 1 Mbps, flexible mailbox/FIFO buffering, automatic retransmission, and acceptance filtering with full-bit compare/mask options.
Peripheral integration includes two independent UARTs (asynchronous/synchronous operation at up to 2 Mbps), four 8/16-bit PPG channels, eight 16-bit input capture and four 16-bit output compare channels, and an 8-channel 8/10-bit ADC with external trigger start - all managed via dedicated interrupt vectors across 8 priority levels and 34 interrupt sources.
