Infineon Technologies MB90F387SPMCR-GSE2

Overview

MB90F387SPMCR-GSE2 from Cypress Semiconductor is a 16-bit F2MC-16LX microcontroller with integrated full-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 min instruction time), supports 8/10-bit A/D conversion across 8 channels, and features UART (SCI), PPG timers, and low-power sleep/watch modes - deployed in automotive body control modules requiring real-time CAN communication and sensor interfacing.

For engineers reviewing the MB90F387SPMCR-GSE2 datasheet, MB90F387SPMCR-GSE2 pinout, MB90F387SPMCR-GSE2 application, or MB90F387SPMCR-GSE2 equivalent, key selection criteria include its 16-bit CPU architecture with 32-bit accumulator, built-in PLL clock multiplication (1×–4×), sub-clock (8.192 kHz) support for watch mode, and verified CAN wake-up capability with external interrupt inputs on P24–P27.

Technical Context

This MCU implements the F2MC-16LX core with 23 addressing modes, enhanced C-language support via system stack pointer and barrel shift instructions, and real-time deterministic interrupt handling (1.5 µs min latency). Its peripheral set includes a dedicated CAN controller with eight message buffers, dual 16-bit reload timers, and an 8/16-bit PPG timer supporting arbitrary-duty pulse generation.

The device integrates analog and digital subsystems on a single CMOS die: AVCC/AVR pins supply isolated analog power and reference for the 8/10-bit A/D converter; MD0–MD2 configure boot mode; and X0/X1 accept 4 MHz crystal input while internal PLL scales to 16 MHz machine clock - enabling precise timing for CAN bit arbitration and SCI serial framing.

FAQ

Does MB90F387SPMCR-GSE2 support CAN FD?

No. The integrated CAN controller complies strictly with ISO 11898-1:2003 (CAN 2.0A/B) and does not implement CAN FD features such as flexible data-rate or extended data length. It supports bit rates from 10 kbps to 1 Mbps using standard CAN frames only.

What is the maximum operating temperature for this device?

The MB90F387SPMCR-GSE2 is rated for industrial temperature range: –40 °C to +85 °C. This is confirmed by Absolute Maximum Ratings and Recommended Operating Conditions in Cypress Document 002-07765 Rev. *A, page 55–57.

Can the 8/10-bit A/D converter perform simultaneous sampling across multiple channels?

No. The A/D converter performs sequential conversions only - even in sequential mode, sampling occurs one channel at a time. The 6.125 µs conversion time includes sampling, and no hardware support exists for simultaneous sample-and-hold across AN0–AN7.

Is external crystal required for CAN operation?

Yes. A 4 MHz crystal connected to X0/X1 is mandatory to generate the base clock for the internal PLL, which produces the 16 MHz machine clock required for accurate CAN bit timing. Sub-clock (8.192 kHz) alone cannot sustain CAN communication.
