Infineon Technologies MB90F387PMT-GE1

Overview

MB90F387PMT-GE1 from Cypress Semiconductor is a 16-bit F2MC-16LX microcontroller with integrated CAN 2.0A/B controller, 64 KB Flash ROM, 2 KB RAM, and 34 GPIO ports including four high-current outputs. It operates at up to 16 MHz (62.5 ns instruction cycle), supports 8/10-bit ADC (8 channels, 6.125 µs conversion), and features low-power modes including Sleep, Watch, and Stop. Used in real-time process control for consumer appliances requiring embedded CAN connectivity.

For engineers reviewing the MB90F387PMT-GE1 datasheet, MB90F387PMT-GE1 pinout, MB90F387PMT-GE1 application, or MB90F387PMT-GE1 equivalent, key selection criteria include its 16-bit CPU architecture with 32-bit accumulator, full-CAN interface with 8 message buffers, LQFP-48 package compatibility, sub-clock (8.192 kHz) support, and Flash-based field programmability for industrial control firmware updates.

Technical Context

The MB90F387PMT-GE1 implements the F2MC-16LX core with 23 addressing modes, enhanced multiply/divide instructions, and barrel shift operations-optimized for C-language compilation and multitasking RTOS use. Its 24-bit internal addressing enables access to a 16 MB memory space, while the 32-bit accumulator supports long-word arithmetic without software emulation.

Peripheral integration includes a dual-mode UART (SCI) with clock-synchronous/asynchronous operation (up to 2 Mbps), an 8/16-bit PPG timer supporting arbitrary-duty pulse generation, and a 16-bit input-capture timer with edge-triggered latching across four channels-enabling precise timing capture in motor control and sensor synchronization applications.

FAQ

Does MB90F387PMT-GE1 support CAN FD?

No. The MB90F387PMT-GE1 implements only classical CAN 2.0A/B protocol (ISO 11898-1), supporting bit rates up to 1 Mbps with 8 message buffers. It lacks CAN FD features such as flexible data-rate, extended data length, and CRC21 checksum. For CAN FD, consider Infineon's XMC4000 or TC3xx families.

What is the maximum operating temperature for MB90F387PMT-GE1?

The MB90F387PMT-GE1 is rated for industrial temperature range: –40°C to +85°C ambient. This is confirmed in Cypress Document 002-07765 Rev. *A, Section "Recommended Operating Conditions", and applies to the LQFP-48 package variant under continuous operation with proper PCB thermal design.

Can the on-chip Flash be reprogrammed in-system?

Yes. The 64 KB Flash ROM supports in-system programming (ISP) via on-chip bootloader using UART (SCI) or dedicated debug interface. Erase/write cycles are rated for 10,000 cycles per sector, with page erase granularity and automatic ECC handling during write operations.

Is an external crystal required for CAN timing accuracy?

Yes. While the device includes a PLL and supports sub-clock (8.192 kHz) for low-power modes, CAN bit timing requires stable base clock accuracy better than ±1%. A 4 MHz or 8 MHz external crystal (X0/X1) is mandatory for reliable CAN communication at rates ≥125 kbps; internal RC oscillator is not specified for CAN use.
