Product details
Overview
CY90F387SPMT-GS-9002E1 from Infineon Technologies (formerly 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 GPIOs including four high-current output ports. It operates from 3.5 V to 5.5 V, supports PLL-based clock multiplication up to 16 MHz, and delivers 62.5 ns minimum instruction execution time - designed for real-time process control in automotive body electronics and industrial automation systems.
For engineers reviewing the CY90F387SPMT-GS-9002E1 datasheet, CY90F387SPMT-GS-9002E1 pinout, CY90F387SPMT-GS-9002E1 application, or CY90F387SPMT-GS-9002E1 equivalent, key selection criteria include its on-chip CAN interface with 8 message buffers, 8/10-bit selectable A/D converter (8 channels, 6.125 µs conversion at 16 MHz), dual 16-bit reload timers, and low-power sleep/watch/stop modes for embedded control nodes requiring deterministic timing and bus wake-up capability.
Technical Context
The CY90F387SPMT-GS-9002E1 implements the F2MC-16LX CPU core with 24-bit addressing, 32-bit accumulator for long-word arithmetic, and 351 instructions supporting bit/byte/word/long-word data types. Its interrupt system features 8 priority levels and 34 sources, including CAN wakeup, DTP, and ICU edge-triggered input capture across four channels.
Peripheral integration includes a full-duplex UART (SCI) with clock-synchronous transfer up to 2 Mbps, 8/16-bit PPG timer (configurable as four 8-bit or two 16-bit channels), 18-bit time-base timer, and watchdog timer with programmable reset cycles from 3.58 ms. All peripherals are memory-mapped and accessible via dedicated I/O registers in the 16 MB address space.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit CAN microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MB90F387 (Cypress legacy part) | Same die, identical Flash/RAM/peripherals; differs only in ordering prefix and packaging traceability | No functional difference; used in legacy designs prior to CY-prefix transition | Select when maintaining backward compatibility with existing PCB layouts and firmware binaries |
| Infineon XMC4200-F64K256 | 32-bit ARM Cortex-M4F core, 256 KB Flash, 48 KB RAM, dual CAN FD, no built-in A/D trigger input (ADTG) | Higher performance, floating-point support, but requires external ADC interface or rework of analog trigger paths | Choose for new designs needing >100 DMIPS, CAN FD upgrade path, or RTOS-based scheduling with larger memory footprint |
Compared with MB90F387, CY90F387SPMT-GS-9002E1 offers identical functionality with updated Infineon branding and logistics traceability; versus XMC4200-F64K256, it trades raw compute power for deterministic 16-bit real-time latency, smaller code size, and direct ADTG hardware coupling - critical for cost-sensitive, safety-class B control loops.

FAQ
Is CY90F387SPMT-GS-9002E1 pin-compatible with MB90F387?
Yes - CY90F387SPMT-GS-9002E1 uses the same LQFP-48 package with identical pin assignment, electrical characteristics, and memory map as MB90F387. The change reflects Infineon's post-acquisition part numbering policy; no PCB or firmware modifications are required for drop-in replacement in existing designs.
What is the maximum CAN bit rate supported at 16 MHz machine clock?
The CY90F387SPMT-GS-9002E1 supports CAN bit rates from 10 kbps to 1 Mbps when operating with a 16 MHz machine clock. Bit timing is configured via the CAN Bit Timing Register (CBTR), allowing precise synchronization with network baud rates including standard automotive values like 500 kbps and 250 kbps.
Does this MCU support in-system programming (ISP) via UART or CAN?
No - CY90F387SPMT-GS-9002E1 does not implement bootloader-based ISP over UART or CAN. Programming requires Cypress/Infineon-compatible debug pods (e.g., MiniProg3 or KitProg2) connected via JTAG/SWD interface; Flash updates must be performed during development or production programming stages.
How is the 8/10-bit A/D converter resolution selected in hardware or firmware?
Resolution is selected dynamically via the A/D Control Register (ADCR) bit ADMD: setting ADMD=0 selects 8-bit mode (256 steps); ADMD=1 selects 10-bit mode (1024 steps). Conversion time remains fixed at 6.125 µs regardless of resolution, as sampling and conversion cycles are internally optimized for worst-case 10-bit accuracy.
