Infineon Technologies MB90F387SPMT-GS-9001

Overview

MB90F387SPMT-GS-9001 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 instruction cycle), 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 automotive body control modules requiring real-time CAN communication and sensor interfacing.

For engineers reviewing the MB90F387SPMT-GS-9001 datasheet, MB90F387SPMT-GS-9001 pinout, MB90F387SPMT-GS-9001 application, or MB90F387SPMT-GS-9001 equivalent, key selection considerations include its 48-pin LQFP package, built-in PLL clock multiplier (1×–4×), 8-message-buffer CAN controller, 6.125 µs A/D conversion time at 16 MHz, and support for C-language development via system stack pointer and enhanced addressing modes.

Technical Context

This MCU implements the F2MC-16LX architecture with 24-bit internal addressing, 32-bit accumulator for long-word arithmetic, and 351 instructions supporting bit/byte/word/long-word data types. Its interrupt subsystem delivers 34 sources across 8 priority levels, with minimum 1.5 µs latency at 16 MHz.

The peripheral set includes one 16-bit free-run timer with 4-channel input capture (ICU), dual 16-bit reload timers, an 8/16-bit PPG timer configurable as four 8-bit or two 16-bit channels, and a dedicated delay interrupt generator for RTOS task switching - all operating independently of CPU execution.

Equivalent & Alternatives

The following parts are listed as comparable options for similar 16-bit CAN microcontroller applications.

Compared with MB90F387S, the MB90F387SPMT-GS-9001 offers identical core functionality but two fewer I/Os - sufficient for compact nodes. Versus CY8C5868LTI-LP097, it delivers deterministic CAN timing and lower power in standby, but lacks programmable analog and USB - making it optimal for cost-sensitive, CAN-dominant embedded control.

FAQ

What is the maximum operating frequency and corresponding instruction cycle time?

The MB90F387SPMT-GS-9001 achieves a maximum machine clock of 16 MHz using its internal PLL (4× multiplication of a 4 MHz crystal), resulting in a minimum instruction execution time of 62.5 ns. This timing is confirmed in the datasheet's "Electrical Characteristics" section under AC characteristics at Vcc = 5.0 V and Ta = 25 °C.

Does this MCU support CAN FD or only classical CAN?

The MB90F387SPMT-GS-9001 implements only classical CAN per ISO 11898-1:2003 (CAN 2.0A/B), with bit rates from 10 kbps to 1 Mbps. It does not support CAN FD features such as flexible data-rate, extended data length, or CRC enhancements - as explicitly stated in the "CAN Controller" section of the datasheet.

How many A/D channels can be converted in sequential mode, and what is the trigger mechanism?

The device supports sequential conversion across up to 8 A/D channels (AN0–AN7). Conversion can be triggered by software command, external pin (P37/ADTG), or internal timer - with the ADTG pin configured as input and enabled via the A/D control register. Each channel conversion takes 6.125 µs at 16 MHz, including sampling time.

Is the Flash memory reprogrammable in-system, and what is the endurance rating?

Yes, the 64 KB on-chip Flash ROM supports in-system programming (ISP) via the on-chip debug interface. The datasheet specifies a minimum endurance of 10,000 write/erase cycles and data retention of 20 years at 85 °C - validated under recommended operating conditions with Vcc = 5.0 V ±10% and Ta ≤ 85 °C.
