Product details
Overview
MB91F587LBPMC-GTK5E1 from Fujitsu (now part of Cypress Semiconductor, now Infineon) is a 32-bit FR family microcontroller featuring a FR core, 512 KB on-chip flash memory, 64 KB RAM, and integrated CAN 2.0B controller. It operates at up to 60 MHz, supports JTAG debugging, and targets automotive body control modules requiring real-time I/O handling and communication robustness.
For engineers reviewing the MB91F587LBPMC-GTK5E1 datasheet, MB91F587LBPMC-GTK5E1 pinout, MB91F587LBPMC-GTK5E1 application, or MB91F587LBPMC-GTK5E1 equivalent, key selection criteria include CAN interface compliance, flash endurance (100k write/erase cycles), operating temperature range (–40°C to +125°C), and AEC-Q100 Grade 2 qualification for automotive use.
Technical Context
This MCU implements Fujitsu's proprietary FR architecture optimized for deterministic interrupt response and low-power operation in automotive subsystems. It integrates a 16-channel 10-bit ADC, 32-bit timer units with PWM output, and dual CAN controllers supporting both standard and extended frames.
The device uses a multi-layer bus architecture with separate instruction and data buses, enabling simultaneous fetch and execution. Its memory protection unit (MPU) supports region-based access control for safety-critical code partitioning, aligning with ISO 26262 ASIL-B development requirements.

FAQ
Is MB91F587LBPMC-GTK5E1 pin-compatible with other FR58x-series MCUs?
Yes - it shares identical 144-pin LQFP mechanical and electrical pinout with MB91F586, MB91F588, and MB91F589 devices. Peripheral register mapping and memory layout are consistent across the series, enabling hardware reuse and firmware portability with minimal configuration changes.
Does this MCU support CAN FD or only classical CAN 2.0B?
MB91F587LBPMC-GTK5E1 supports only CAN 2.0B (up to 1 Mbps), not CAN FD. Its dual CAN controllers implement full mailbox-based message handling with hardware acceptance filtering, but lack the extended data length and bit-rate switching capabilities defined in ISO 11898-1:2015.
What debug tools are officially supported for firmware development?
Fujitsu's official toolchain includes the FR Family IDE (based on Eclipse), FR Simulator, and the FDT-USB-JTAG debugger. Third-party support includes Lauterbach TRACE32 and iSYSTEM winIDEA, both validated for flash programming, real-time tracing, and ASIL-B diagnostic coverage analysis.
Is there a qualified automotive-grade version with extended temperature range?
No - MB91F587LBPMC-GTK5E1 is qualified only for AEC-Q100 Grade 2 (–40°C to +125°C). Fujitsu did not release a Grade 1 (–40°C to +150°C) variant of this specific part number; alternative solutions require migration to S32K or AURIX families for extended temperature support.
