Infineon Technologies MB90F387SPMT-GS-9002

Overview

MB90F387SPMT-GS-9002 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 at up to 16 MHz (62.5 ns min. instruction time), supports 8/10-bit A/D conversion across 8 channels, and features dual 16-bit reload timers, 4-channel input capture, and low-power sleep/watch/stop modes. Used in automotive body control modules requiring real-time CAN communication and analog sensing.

Technical Context

This MCU implements the F2MC-16LX architecture with 24-bit internal addressing, 32-bit accumulator for long-word arithmetic, and 23 addressing modes optimized for C-language compilation and multitasking. Its instruction set includes enhanced multiply-divide, barrel shift, and bit-processing instructions.

The peripheral subsystem integrates a dedicated CAN controller with eight message buffers and programmable bit timing (10 kbps–1 Mbps), an 8/10-bit SAR A/D converter with external trigger (ADTG pin), and four independent 16-bit input-capture units synchronized to a free-run timer-enabling precise edge-timed event logging for motor position or encoder feedback.

FAQ

What is the maximum CAN bit rate supported by MB90F387SPMT-GS-9002?

The MB90F387SPMT-GS-9002 supports CAN bit rates from 10 kbps to 1 Mbps when operating with a 16 MHz machine clock. Bit timing is fully programmable via the CAN controller's BTR register, allowing precise configuration for network topology and oscillator tolerance. The controller complies with both CAN 2.0A and 2.0B specifications, including extended frame support.

Does MB90F387SPMT-GS-9002 support in-system programming of its Flash memory?

Yes, MB90F387SPMT-GS-9002 supports in-system programming (ISP) via its on-chip bootloader and serial interface (SCI). Flash programming requires the MB2145-507 emulator pod or compatible Cypress development tools. The program patch function enables selective sector updates without erasing the entire Flash array, preserving critical calibration data during field upgrades.

How many A/D conversion channels can be triggered simultaneously using the ADTG pin?

The ADTG pin (P37) triggers conversion on a single selected A/D channel-not multiple channels simultaneously. However, the device supports sequential conversion mode, where up to eight channels (AN0–AN7) can be converted in programmable order after one ADTG edge. Each conversion completes in 6.125 µs at 16 MHz, enabling rapid multi-channel sampling within tight timing windows.

What are the voltage requirements for AVcc and AVR pins during A/D operation?

AVcc must be supplied with a clean 5.0 V ±10% (4.5–5.5 V) analog power source, decoupled with ≥1 µF ceramic capacitor near Pin 1. AVR serves as the positive reference (Vref+) and may be connected to AVcc or a lower-stability external reference (≤ AVcc); if using internal reference, AVR must be tied to AVcc. Noise on either pin directly impacts A/D accuracy and linearity.
