Infineon Technologies MB90F543GSPF-GS-9002

Overview

MB90F543GSPF-GS-9002 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 A/D conversion across 8 channels (26.3 µs per channel), and targets automotive body control modules requiring robust real-time communication and mixed-signal processing.

For engineers reviewing the MB90F543GSPF-GS-9002 datasheet, MB90F543GSPF-GS-9002 pinout, MB90F543GSPF-GS-9002 application, or MB90F543GSPF-GS-9002 equivalent, key selection criteria include dual CAN channel support, Flash programmability with block protection, 16-bit I/O timer with 8-channel input capture, and operation over −40 °C to +105 °C in 4.5–5.5 V supply range.

Technical Context

The MB90F543GSPF-GS-9002 implements the proprietary F2MC-16LX CPU core with 23 addressing modes, 32-bit accumulator for extended precision arithmetic, and enhanced C-language support via system stack pointer and barrel shift instructions. Its interrupt subsystem delivers 8 priority levels and 34 interrupt sources, including dedicated CAN message reception and transmission events.

Dual FULL-CAN controllers operate independently at up to 1 Mbps, each supporting flexible mailbox/FIFO buffering, automatic retransmission on error, and acceptance filtering via full-bit compare or dual partial masks. The external bus interface enables expansion up to 16 Mbytes using 8-/16-bit data width, synchronized by RD/WR/HRQ/HAK signals.

Key Specifications

Pinout & Package

FAQ

What is the maximum CAN bit rate supported by MB90F543GSPF-GS-9002?

The MB90F543GSPF-GS-9002 supports CAN bit rates up to 1 Mbps per channel, compliant with ISO 11898-1:2003 (CAN 2.0A/B). This is achieved using the on-chip CAN controllers' programmable baud rate prescalers and synchronization jump width settings, validated under worst-case propagation delay conditions at 16 MHz system clock.

Does MB90F543GSPF-GS-9002 support in-system programming of Flash memory?

Yes. The device supports in-system programming via its built-in Flash algorithm, enabling erase-suspend/resume, block-wise write/erase, and status flag polling. Programming requires only standard VCC and VPP (12.5 V) supply pins; no external programmer hardware is needed beyond a UART or CAN-based bootloader.

How many analog input channels does MB90F543GSPF-GS-9002 provide, and what resolution options are available?

It provides 8 analog input channels (AN0–AN7) with selectable 8-bit or 10-bit resolution. Conversion time is fixed at 26.3 µs per channel regardless of resolution, and sampling can be triggered externally (e.g., by timer overflow or CAN message arrival) to synchronize with mechanical events.

What power-saving modes are implemented, and which peripherals remain active in each?

Three low-power modes are supported: Sleep (CPU clock stopped, CAN/UART/timers retain operation), Stop (oscillator halted, RAM retained, wake-on-CAN/INT), and Hardware Stand-by (minimal current draw, only reset and wake pins active). In Stop mode, CAN controllers maintain bus synchronization and can generate interrupts on message receipt without CPU involvement.
