Infineon Technologies MB89663P-GT-XXX-SH

Overview

MB89663P-GT-XXX-SH from Fujitsu is an 8-bit F2MC-8L microcontroller with 64 KB on-chip ROM, 2 KB RAM, and integrated CAN 2.0B controller supporting up to 1 Mbps data rate. It features a 16-bit ALU, dual 16-bit accumulators (A/T architecture), and programmable I/O port levels for automotive ground offset tolerance. Used in body control modules for vehicle door/window actuation and lighting control.

For engineers reviewing the MB89663P-GT-XXX-SH datasheet, MB89663P-GT-XXX-SH pinout, MB89663P-GT-XXX-SH application, or MB89663P-GT-XXX-SH equivalent, key selection criteria include CAN bus timing compliance, automotive-level I/O voltage thresholds (VIL = 0.5×Vcc), clock modulation for EMI reduction, and support for sub-clock RUN/SLEEP/STOP power modes.

Technical Context

The MB89663P-GT-XXX-SH implements Fujitsu's F2MC-8L CPU core with 32 register banks (8×8-bit each) and two 16-bit accumulators enabling fast context switching during CAN interrupt handling. It integrates a full CAN 2.0B controller with message objects, acceptance filtering, and automatic retransmission.

Its clock system supports main oscillator (up to 20 MHz), sub-clock (32.768 kHz), and dynamic GEAR mode for CPU cycle time scaling (0.4–6.5 μs at 10 MHz). Clock modulation reduces EMI peak emissions by spreading the fundamental frequency spectrum.

Key Specifications

Pinout & Package

FAQ

What is the maximum CAN bit rate supported by MB89663P-GT-XXX-SH?

The MB89663P-GT-XXX-SH supports CAN 2.0B with a maximum bit rate of 1 Mbps, achieved using its programmable bit timing registers and internal oscillator accuracy of ±1.5% over temperature and voltage. This allows direct connection to standard high-speed CAN transceivers without external clock trimming.

Does MB89663P-GT-XXX-SH include an on-chip debug interface?

Yes, it supports Compact-ICE (C-ICE) debugging via a 5-pin SWD-compatible interface. This enables real-time trace, multi-level hardware breakpoints, and C-language source-level debugging under Windows-based Softune Workbench without requiring additional JTAG hardware.

Can MB89663P-GT-XXX-SH operate from a single 5 V supply?

Yes, it operates from a single 4.5–5.5 V supply across –40°C to +125°C. Its internal voltage regulator provides stable core voltage, and separate AVCC/VSS pins isolate analog reference for any optional on-chip peripherals like ADC or DAC.

Is MB89663P-GT-XXX-SH qualified to AEC-Q100?

While Fujitsu states future automotive MCUs will be fully AEC-Q100 compliant, the MB89663P-GT-XXX-SH was designed and tested to meet ISO/TS 16949 requirements and has been deployed in production automotive body electronics meeting OEM-specific qualification protocols including extended temperature cycling and ESD immunity per ISO 10605.
