Infineon Technologies MB89623P-GT-XXX-SH

Overview

MB89623P-GT-XXX-SH from Fujitsu is an 8-bit microcontroller based on the F2MC-8L CPU core, featuring 64 KB program memory address space, dual 16-bit accumulators with A-T architecture, and support for 1/8/16-bit data operations. It includes programmable port levels (TTL, CMOS, and automotive-level VIL = 0.5×Vcc), clock modulation for EMI reduction, and LIN USART supporting up to 4 MBaud - deployed in automotive body control modules requiring robust low-voltage operation and noise immunity.

For engineers reviewing the MB89623P-GT-XXX-SH datasheet, MB89623P-GT-XXX-SH pinout, MB89623P-GT-XXX-SH application, or MB89623P-GT-XXX-SH equivalent, key selection criteria include automotive-level I/O threshold compatibility, embedded clock modulation capability, LIN protocol hardware acceleration, and F2MC-8L register bank context-switch performance for real-time interrupt handling.

Technical Context

The MB89623P-GT-XXX-SH implements Fujitsu's F2MC-8L CPU core with seven 16-bit registers and up to 32 × 8-register banks enabling fast interrupt response via bank switching. It supports GEAR power-saving mode with four selectable CPU cycle time ratios (e.g., 0.4–6.5 μs at 10 MHz) and SUB RUN mode using sub-clock while disabling main oscillator.

Its LIN USART integrates dedicated hardware protocol control, SPI mode, and baud rate flexibility up to 4 MBaud. Clock modulation spreads spectral energy across a defined bandwidth to meet IEC 61967-4 EMI limits - verified on related MB90F394 devices under identical architecture.

Key Specifications

Pinout & Package

MB89623P-GT-XXX-SH is housed in a 64-pin LQFP package (10 mm × 10 mm, 0.5 mm pitch) with exposed thermal pad. Pin functions align with F2MC-8L standard I/O mapping, including dedicated LIN_TX/LIN_RX, CLKIN/CLKOUT, RESET, and multi-function ports configurable as general-purpose I/O or peripheral signals.

FAQ

What voltage range does the MB89623P-GT-XXX-SH support?

The MB89623P-GT-XXX-SH operates across 2.7 V to 5.5 V, enabling direct integration into 12 V automotive systems with standard DC-DC regulation. Its I/O pins support programmable thresholds-including automotive-level VIL = 0.5×Vcc-ensuring noise-tolerant operation even with ground offsets up to ±2 V typical in vehicle harnesses.

Does this MCU include on-chip debug capability?

Yes, the MB89623P-GT-XXX-SH supports Compact-ICE (C-ICE) debugging via dedicated on-chip emulation interface. It enables real-time trace, multi-level hardware breakpoints, and mixed C/assembly debugging under Windows XP/NT/2000, compatible with Fujitsu's Softune Workbench development environment.

Is the LIN interface fully hardware-accelerated?

Yes, the LIN USART provides full hardware acceleration including automatic sync field detection, break delimiter generation, checksum calculation (classic and enhanced), and frame timing control. This eliminates CPU intervention during frame transmission/reception, reducing firmware overhead by ~20% compared to software-implemented LIN stacks.

What packaging options are available for this part?

The MB89623P-GT-XXX-SH is supplied exclusively in a 64-pin LQFP package (10 mm × 10 mm, 0.5 mm pitch) with exposed thermal pad. The "XXX" suffix denotes lead-free (Pb-free) RoHS-compliant finish and tape-and-reel packaging per JEDEC J-STD-020 moisture sensitivity level 3.
