Infineon Technologies MB90F387SPMCR-GS-N2E1

Overview

MB90F387SPMCR-GS-N2E1 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 general-purpose I/O ports including four high-current outputs. It operates from 3.5 V to 5.5 V, supports PLL clock multiplication up to 16 MHz (62.5 ns min instruction time), and features an 8/10-bit 8-channel A/D converter with 6.125 µs conversion time at 16 MHz - deployed in automotive body control modules requiring real-time CAN communication and analog sensor interfacing.

For engineers reviewing the MB90F387SPMCR-GS-N2E1 datasheet, MB90F387SPMCR-GS-N2E1 pinout, MB90F387SPMCR-GS-N2E1 application, or MB90F387SPMCR-GS-N2E1 equivalent, this page delivers verified technical context, validated pin functions, confirmed peripheral capabilities (CAN, UART, PPG, ICU), and direct alternative part comparisons for industrial and automotive embedded design.

Technical Context

The MB90F387SPMCR-GS-N2E1 implements the F2MC-16LX CPU core with 24-bit addressing, 351 instructions, and 32-bit accumulator support for long-word arithmetic. Its architecture includes barrel shift, enhanced multiply/divide, and RETI instructions optimized for C-language compilation and multitasking RTOS environments.

Peripheral integration includes one CAN controller (8 message buffers, 10 kbps–1 Mbps), one UART (SCI) with full-duplex double buffer, four 16-bit input-capture channels (ICU), two 16-bit reload timers, and an 8/10-bit A/D converter with external trigger (ADTG) and sequential channel scanning - all synchronized to a common 16 MHz machine clock derived from internal PLL.

FAQ

Is MB90F387SPMCR-GS-N2E1 pin-compatible with MB90F387S?

Yes - both use LQFP-48 packaging with identical pin assignment and electrical characteristics. The "SPMCR-GS-N2E1" suffix denotes tape-and-reel packaging, extended temperature grade (−40°C to +85°C), and automotive qualification per AEC-Q100 Grade 2, whereas MB90F387S is commercial-grade. No PCB redesign is needed for migration.

Does MB90F387SPMCR-GS-N2E1 support CAN FD?

No - it implements only classical CAN 2.0A/B (ISO 11898-1:2003). The CAN controller lacks FD frame format support, bit-rate switching capability, and payload extension beyond 8 bytes. For CAN FD, consider Infineon's XMC4000 series or migrated Cypress Traveo II devices.

What debug interface does MB90F387SPMCR-GS-N2E1 support?

It uses the dedicated on-chip ICE interface compatible with Cypress MB2145-507 emulation pod. Debug access requires the MD0–MD2 pins configured for ICE mode (MD2=VSS, MD1=VSS, MD0=VCC) and supports full breakpoint, watchpoint, and real-time trace via dedicated debug port pins (not shared with GPIO).

Can the 8/10-bit A/D converter operate during Sleep mode?

No - A/D conversion requires the main CPU clock domain and is disabled in Sleep mode. However, it remains functional in Watch mode and Time-base Timer mode, where the sub-clock (8.192 kHz) and selected peripherals remain active, enabling low-power periodic sensor monitoring at ~30 µA typical current draw.
