Infineon Technologies MB90F387SPMCR-G-EF2

Overview

MB90F387SPMCR-G-EF2 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 general-purpose I/O 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, input-capture ICU, and low-power sleep/watch/stop modes. Used in real-time process control for consumer appliances requiring embedded CAN connectivity.

For engineers reviewing the MB90F387SPMCR-G-EF2 datasheet, MB90F387SPMCR-G-EF2 pinout, MB90F387SPMCR-G-EF2 application, or MB90F387SPMCR-G-EF2 equivalent, key selection criteria include its 16-bit CPU with 32-bit accumulator, built-in PLL clock multiplier (1×–4×), sub-clock (8.192 kHz) support, CAN wake-up capability, and LQFP-48 package compatibility with industrial temperature range operation.

Technical Context

The MB90F387SPMCR-G-EF2 implements the F2MC-16LX architecture with 24-bit internal addressing, 23 addressing modes, and enhanced C-language support via system stack pointer and barrel-shift instructions. Its 32-bit accumulator enables native long-word arithmetic, while the 4-byte instruction queue improves throughput in deterministic real-time tasks.

Peripheral integration includes one CAN controller (8 message buffers, 10 kbps–1 Mbps), one UART (SCI) with full-duplex double buffer, eight-channel 8/10-bit A/D converter (6.125 µs conversion at 16 MHz), and dual 16-bit reload timers with configurable count clocks (0.25–2.0 µs). All timers support external event counting and edge-triggered capture.

FAQ

Is MB90F387SPMCR-G-EF2 pin-compatible with other MB90385-series devices?

Yes - it shares the LQFP-48 footprint and identical pin assignment with MB90F387, MB90387, and MB90F387S. Differences are limited to ROM type (Flash vs. mask) and I/O count (34 vs. 36), with no changes to peripheral pin mapping or electrical characteristics.

Does MB90F387SPMCR-G-EF2 require an external CAN transceiver?

Yes - the device integrates only the CAN protocol controller (MAC layer); an external physical-layer transceiver (e.g., TJA1042, SN65HVD230) is required for bus connection, termination, and ESD protection per ISO 11898-2.

What is the maximum achievable CAN bit rate with MB90F387SPMCR-G-EF2?

At 16 MHz machine clock, the CAN controller supports bit rates from 10 kbps to 1 Mbps. The actual maximum depends on bus length and topology - 1 Mbps is achievable on short, well-terminated buses (<40 m), while longer runs require lower rates per CAN physical layer specifications.

Can the 8/10-bit A/D converter operate independently of CPU intervention?

Yes - the A/D converter supports automatic sequential conversion across up to 8 channels triggered by external signal (P37/ADTG) or internal timer, with results stored in dedicated registers. DMA is not present, but interrupt-driven transfer minimizes CPU load during acquisition.
