Overview
MB90F543GPFV-G 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 QFP-100 package. It operates at up to 16 MHz system clock (62.5 ns min instruction time), supports 8/10-bit 8-channel ADC (26.3 µs conversion), and targets automotive body control modules requiring robust real-time communication and mixed-signal processing.
For engineers reviewing the MB90F543GPFV-G datasheet, MB90F543GPFV-G pinout, MB90F543GPFV-G application, or MB90F543GPFV-G equivalent, key selection criteria include dual CAN channel support, Flash programmability with block protection, 16-bit I/O timer with 8-input capture/4-output compare, UART0/SCI dual serial interfaces with synchronous/asynchronous modes, and operation over −40 °C to +105 °C.
Technical Context
The MB90F543GPFV-G implements the proprietary F2MC-16LX CPU core with 32-bit accumulator, 23 addressing modes, and enhanced C-language support including system stack pointer and barrel shift instructions. Its dual CAN controllers provide flexible mailbox/FIFO buffering, automatic retransmission, and 1 Mbps data rate compliance with ISO 11898.
Peripheral integration includes four 8/16-bit PPG timers, two 16-bit reload timers, one 16-bit free-run timer, extended intelligent I/O service (EI2OS), and external bus interface supporting up to 16 Mbytes address space - all synchronized to a dual-clock system (main PLL + 32 kHz sub-clock) for deterministic low-power operation.
