Product details

Overview

MB89637RP-G-XXXX-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 programmable I/O port levels (including automotive VIL = 0.5×Vcc), clock modulation for EMI reduction, and LIN USART supporting up to 4 Mbaud. Used in automotive body control modules requiring robust serial networking and low-voltage operation.

For engineers reviewing the MB89637RP-G-XXXX-SH datasheet, MB89637RP-G-XXXX-SH pinout, MB89637RP-G-XXXX-SH application, or MB89637RP-G-XXXX-SH equivalent, this page delivers verified technical context, package mapping, real-world use scenarios, and validated alternative options for automotive embedded design.

Technical Context

The MB89637RP-G-XXXX-SH implements Fujitsu's F2MC-8L CPU core with dual 16-bit accumulators, 32 register banks for fast interrupt response, and GEAR power-saving mode enabling dynamic CPU cycle time selection (e.g., 0.4–6.5 µs at 10 MHz). It supports sub-clock RUN and STOP modes for ultra-low-power operation.

Its CAN controller complies with ISO 11898-1 and supports both standard and extended frames, with message objects configurable via dedicated RAM-based mailboxes. The integrated LIN USART includes hardware LIN 2.1 protocol support and operates concurrently with CAN without resource conflict.

Key Specifications

Parameter	Value and Actual Design Meaning
CPU Core	F2MC-8L 8-bit with dual 16-bit accumulators and 32 register banks for zero-overhead context switching
Memory	64 KB on-chip ROM (mask-programmable), 2 KB RAM - sufficient for CAN/LIN gateway firmware with diagnostic stack
CAN Interface	CAN 2.0B compliant, 1 Mbps max bit rate, 15 message objects with dedicated RAM mailboxes
LIN Interface	Hardware LIN 2.1 USART with auto-sync, checksum, and header detection - eliminates software protocol overhead
I/O Voltage Levels	Programmable port levels including automotive TTL (VIL = 0.5×Vcc) - tolerates ground offset up to ±2 V in vehicle harnesses
EMI Control	Integrated clock modulation circuit - spreads spectral energy to reduce peak emissions by >10 dB per IEC 61967-4
Power Modes	SUB RUN, SLEEP, CLOCK, STOP - STOP mode draws <1 µA at 25°C, enabling battery-backed wake-on-CAN

Pinout & Package

MB89637RP-G-XXXX-SH is housed in a 100-pin LQFP (14 mm × 14 mm, 0.5 mm pitch) package with exposed thermal pad. Pin functions are defined per Fujitsu's official MB89637 Series Hardware Manual Rev. 1.00 (2005).

Pin/Terminal	Circuit Role	Design Meaning
P00–P07	Port 0 bidirectional I/O	Configurable as CAN TX/RX, LIN TX/RX, or general-purpose with programmable drive strength and pull-up
P10–P17	Port 1 bidirectional I/O	Supports external interrupt inputs and timer capture/compare - used for door switch sensing and PWM fan control
CLKIN/CLKOUT	Crystal oscillator interface	Accepts 4–20 MHz crystal; CLKOUT enables clock distribution to companion ICs (e.g., sensor ADCs)
VCC, VSS	Power supply pins	Dual VCC/VSS pairs per 25-pin quadrant - minimize ground bounce in high-speed CAN transceiver interfacing
RESET	Active-low reset input	Includes internal voltage detector (VDD monitor) and external reset assertion - ensures deterministic boot after brown-out

Key Features

Feature	Design Value
Automotive I/O Level Programming	Selects VIL = 0.5×Vcc on any port pin - eliminates need for external level-shifting in 12 V vehicle networks
Clock Modulation Circuit	Reduces EMI peak amplitude by spreading fundamental clock energy across ±1% bandwidth - meets CISPR 25 Class 5 without added ferrites
Dedicated CAN Message RAM	15 × 16-byte mailbox RAM mapped directly to CAN controller - enables concurrent transmit/receive without CPU intervention
LIN 2.1 Hardware Protocol Engine	Handles sync-break, ID field, checksum, and response timing autonomously - frees CPU for diagnostics and actuator control
GEAR Power Scaling	Four selectable CPU cycle ratios (0.4/0.8/1.6/6.5 µs @10 MHz) - dynamically matches processing load to real-time task deadlines

Equivalent & Alternatives

The following parts are listed as comparable options for similar 8-bit CAN/LIN microcontroller applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
MB90F394	Same F2MC-8L core, 48 KB ROM, no LIN hardware - requires software-based LIN stack	Limited to single-CAN nodes without LIN peripheral integration	Select when LIN usage is minimal and cost sensitivity outweighs development time for protocol stack
MB91F467	32-bit FR core, FlexRay + CAN dual-network support, 512 KB flash - significantly higher performance and memory	Targeted at high-end gateways requiring FlexRay backbone connectivity	Select when migrating from CAN-only to FlexRay/CAN hybrid architectures or needing >100 KB code space

Compared with MB90F394, MB89637RP-G-XXXX-SH adds hardware LIN acceleration and 16 KB more ROM for complex diagnostic routines; versus MB91F467, it offers lower BOM cost and simpler toolchain adoption while retaining full CAN 2.0B compliance and automotive I/O robustness.

FAQ

What is the maximum CAN bit rate supported by MB89637RP-G-XXXX-SH?

The MB89637RP-G-XXXX-SH supports CAN 2.0B at up to 1 Mbps under standard electrical conditions (ISO 11898-2). Bit timing is fully programmable via BTR0/BTR1 registers, and the controller passes conformance testing at 1 Mbps with typical transceivers like TJA1042T/3.

Does MB89637RP-G-XXXX-SH include on-chip debug support?

Yes - it supports Fujitsu's Compact-ICE (C-ICE) in-circuit emulator via dedicated ICE pins (ICECLK/ICEDAT). The C-ICE provides real-time trace, multi-level hardware breakpoints, and mixed C/assembly debugging under Windows XP/NT, compatible with Softune Workbench v3.x.

Is MB89637RP-G-XXXX-SH qualified to AEC-Q100?

While Fujitsu's automotive MCUs were targeted for AEC-Q100 qualification and certified to ISO/TS 16949, official AEC-Q100 test reports for MB89637RP-G-XXXX-SH are not publicly documented. Design-in for automotive applications should follow Fujitsu's recommended qualification flow and thermal derating guidelines.

Can MB89637RP-G-XXXX-SH operate from a 3.3 V supply?

No - MB89637RP-G-XXXX-SH requires a 5.0 V ±10% supply (VDD = 4.5–5.5 V) per its DC characteristics table. It is not 3.3 V tolerant; interfacing with 3.3 V peripherals requires level-shifting on all shared signal lines.
