It operates at up to 66 MHz, supports IEEE 1149.1 JTAG debugging, and targets automotive body electronics and industrial control modules.
For engineers reviewing the MB91F662PMC-G-N2E1 datasheet, MB91F662PMC-G-N2E1 pinout, MB91F662PMC-G-N2E1 application, or MB91F662PMC-G-N2E1 equivalent, key selection criteria include CAN channel count, Flash/RAM size, LQFP-120 package compatibility, and support for automotive-grade temperature range (–40°C to +125°C).
Technical Context
This MCU implements Fujitsu's FR60 core architecture with 32-bit RISC instruction set, 5-stage pipeline, and hardware multiplier/divider. It integrates dual CAN controllers (CAN0/CAN1), LIN 2.1-compatible UARTs, and a 12-bit ADC with 24 channels and 1 μs conversion time.
The device includes a programmable watchdog timer, real-time clock (RTC) with calendar function, and power management unit supporting STOP, SLEEP, and STANDBY low-power modes. Memory protection unit (MPU) enforces code/data access permissions across four regions.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 32-bit automotive microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| RH850/F1L-M | 40 MHz max frequency, 384 KB Flash, single CAN channel, no on-chip RTC | Lacks dual CAN and calendar RTC; requires external RTC for timestamping | Preferred where cost sensitivity outweighs dual-CAN requirement and external RTC is acceptable |
| S32K144M | Cortex-M4F core, 512 KB Flash, dual CAN FD, 16-bit ADC, no MPU | Supports CAN FD data rates but lacks hardware MPU for ASIL-B partitioning | Chosen when CAN FD bandwidth is critical and functional safety relies on software-based partitioning |
Compared with RH850/F1L-M and S32K144M, MB91F662PMC-G-N2E1 uniquely combines dual CAN 2.0B, hardware MPU, and calendar RTC in a single AEC-Q100 Grade 2 package-enabling compact, safety-aware body electronics without external components.

FAQ
What is the maximum operating frequency of the MB91F662PMC-G-N2E1?
The MB91F662PMC-G-N2E1 operates at a maximum CPU frequency of 66 MHz, achieved using an internal PLL that multiplies an external 1–20 MHz crystal input. This frequency is fully supported across the full –40°C to +125°C temperature range and meets AEC-Q100 Grade 2 requirements for timing stability.
Does this MCU support CAN FD or only classical CAN?
The MB91F662PMC-G-N2E1 supports only classical CAN 2.0B (up to 1 Mbps), not CAN FD. Its dual CAN controllers implement full CAN 2.0B compliance with message object buffers, acceptance filtering, and error handling per ISO 11898-1, but lack the variable bit rate and extended data length features of CAN FD.
Is there an official evaluation board available for this part?
Yes-Infineon offers the MB91F662 Evaluation Board (EB-662), which includes on-board JTAG debugger, CAN transceivers, ADC test points, and jumper-configurable I/O headers. It supports all peripherals and operates across the full industrial temperature range with external power regulation.
What debug interface does the MB91F662PMC-G-N2E1 use?
The device uses IEEE 1149.1-compliant JTAG (TCK/TMS/TDI/TDO/TRST) for boundary scan and on-chip debugging. It supports real-time trace via SWO pin and full register visibility through standard tools including Lauterbach TRACE32 and IAR Embedded Workbench for FR.
