Infineon Technologies MB90F548GSPF-G

Overview

MB90F548GSPF-G from Cypress Semiconductor is a 16-bit F2MC-16LX microcontroller with dual FULL-CAN interfaces (CAN V2.0A/B), 128 KB Flash ROM, 4 KB RAM, and 100-pin LQFP package. It operates at up to 16 MHz (via on-chip PLL ×4), delivers 62.5 ns minimum instruction execution time, and targets automotive body control and industrial CAN-based distributed systems.

For engineers reviewing the MB90F548GSPF-G datasheet, MB90F548GSPF-G pinout, MB90F548GSPF-G application, or MB90F548GSPF-G equivalent, key selection criteria include dual-CAN timing compliance, Flash programmability with block protection, 8/10-bit A/D conversion across 8 channels, and support for external bus expansion up to 16 Mbytes.

Technical Context

The MB90F548GSPF-G implements the proprietary F2MC-16LX CPU core with 23 addressing modes, 32-bit accumulator for extended precision, and enhanced C-language support via system stack pointer and barrel shift instructions. Its interrupt subsystem supports 8 priority levels and 34 interrupt sources including delayed task-switching triggers.

Dual FULL-CAN controllers provide flexible mailbox/FIFO hybrid buffering, automatic retransmission, remote frame response, and acceptance filtering with full-bit compare/mask options. The peripheral set includes four 8/16-bit PPG timers, eight input capture channels, four output compare channels, and dual UARTs with synchronous/asynchronous modes up to 2 Mbps.

FAQ

What is the maximum CAN bit rate supported by MB90F548GSPF-G?

The MB90F548GSPF-G supports CAN bit rates up to 1 Mbps per channel, fully compliant with ISO 11898-1:2003 CAN V2.0B specification. This is achieved using internal clock division and configurable bit timing registers, with no external oscillator dependency beyond the main system clock source.

Does MB90F548GSPF-G support in-system programming of Flash memory?

Yes - MB90F548GSPF-G supports full in-system programming via its on-chip bootloader. Flash operations include automatic programming, erase-suspend/resume, and block-level protection controlled by external VPP voltage, enabling secure field firmware updates without removing the device from the PCB.

How many general-purpose I/O pins does MB90F548GSPF-G provide?

The MB90F548GSPF-G provides 81 general-purpose I/O ports, all individually configurable as input, output, or peripheral function (e.g., UART, CAN, timer). Each port supports push-pull drive strength and Schmitt-trigger input hysteresis for noise immunity in electrically noisy automotive environments.

Is MB90F548GSPF-G qualified for automotive applications?

Yes - MB90F548GSPF-G is rated for operation from −40 °C to +105 °C and designed to meet automotive reliability requirements. While not explicitly AEC-Q100 certified in public documentation, its process technology (0.5 µm CMOS), test coverage, and qualification history align with Tier-1 automotive supplier validation practices for body control applications.
