Infineon Technologies MB90F543GSPF-GS-9004

Overview

MB90F543GSPF-GS-9004 from Cypress Semiconductor is a 16-bit F2MC-16LX microcontroller with Flash ROM, dual FULL-CAN interfaces (CAN 2.0A/B), 128 KB on-chip Flash, 6 KB RAM, and QFP-100 package - designed for automotive body control and industrial real-time control systems requiring robust communication and deterministic timing.

For engineers reviewing the MB90F543GSPF-GS-9004 datasheet, MB90F543GSPF-GS-9004 pinout, MB90F543GSPF-GS-9004 application, or MB90F543GSPF-GS-9004 equivalent, key selection criteria include CAN channel count, Flash endurance (10,000 erase cycles), 62.5 ns minimum instruction time at 16 MHz, 8/10-bit 8-channel ADC with 26.3 µs conversion, and dual-clock system support for low-power operation.

Technical Context

This microcontroller 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. It integrates two independent FULL-CAN controllers compliant with ISO 11898-1:2003, each supporting up to 1 Mbps, flexible mailbox/FIFO buffering, and automatic retransmission.

The peripheral subsystem includes four 8/16-bit PPG timers, eight 16-bit input capture channels, four 16-bit output compare channels, dual UARTs (SCI) with synchronous/asynchronous modes up to 2 Mbps, and an external bus interface supporting 16 MB address space - all synchronized to a PLL-derived system clock scalable from ×1 to ×4 of the crystal oscillator.

FAQ

What is the maximum CAN bit rate supported by MB90F543GSPF-GS-9004?

The device supports up to 1 Mbps per CAN channel, compliant with ISO 11898-1:2003. This maximum rate is achievable with proper termination, cable length ≤ 40 m, and oscillator tolerance ≤ ±0.1% - verified in Cypress application note AN95124 for MB90540G-series CAN timing validation.

Does MB90F543GSPF-GS-9004 support in-application programming (IAP) of Flash memory?

Yes - it implements embedded Flash algorithm commands (Write/Erase/Erase-Suspend/Resume) with completion flag polling. IAP requires disabling interrupts during critical sections and using the fixed boot vector to jump to Flash-resident loader code, as detailed in Section 5.4 of datasheet 002-07696 Rev. *B.

How many general-purpose I/O ports does MB90F543GSPF-GS-9004 provide?

The device provides 81 programmable general-purpose I/O ports, configurable bit-wise as input, output, or peripheral function (e.g., UART, CAN, ADC). All ports feature Schmitt-trigger inputs and push-pull outputs, with individual direction and data register control per pin group.

Is the 32-bit accumulator accessible in all addressing modes?

No - the 32-bit accumulator is explicitly used only in extended arithmetic instructions (e.g., MULS.L, DIVS.L) and cannot be directly loaded/stored via standard MOV instructions. Its use is restricted to long-word multiplication/division and precision calculation sequences, as defined in the F2MC-16LX instruction set manual section 3.2.4.
