Product details
Overview
MB90F387SPMT-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), and delivers 62.5 ns minimum instruction execution time-designed for real-time process control in automotive body electronics and industrial sensor nodes.
For engineers reviewing the MB90F387SPMT-GS-N2E1 datasheet, MB90F387SPMT-GS-N2E1 pinout, MB90F387SPMT-GS-N2E1 application, or MB90F387SPMT-GS-N2E1 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), and low-power standby modes (Sleep, Watch, Stop) enabling battery-operated embedded systems.
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 interrupt system supports 8 priority levels and 34 sources-including CAN wakeup, DTP/external interrupts (4 channels), and delay-interrupt generation for RTOS task switching.
The peripheral set includes dual 16-bit reload timers (0.25–2.0 µs count resolution), a 16-bit input-capture timer (4 channels, edge-triggered latching), 8/16-bit PPG timer (2×16-bit or 4×8-bit PWM), UART with full-duplex double buffer, and an 8/10-bit A/D converter with external trigger capability via P37/ADTG.

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 |
|---|---|---|---|
| Infineon XC2267M-104F80L | TriCore 32-bit core; 80 MHz max; 512 KB Flash; no on-chip A/D trigger pin | Higher performance for complex motor algorithms; lacks hardware ADTG pin-requires GPIO + ISR for trigger sync | Select when migrating to 32-bit architecture with CAN FD support and >100 DMIPS needed |
| Renesas RL78/F13 | 16-bit RL78 core; 32 MHz max; 128 KB Flash; 12-bit A/D; built-in LIN PHY | Lower power (120 µA/MHz); LIN instead of CAN; smaller memory footprint | Select for cost-sensitive LIN-based nodes where CAN bandwidth >100 kbps is unnecessary |
Compared with XC2267M and RL78/F13, MB90F387SPMT-GS-N2E1 uniquely balances legacy 16-bit efficiency, full-CAN 2.0B compliance, hardware A/D triggering, and five low-power modes-making it optimal for retrofitting CAN-based automotive ECUs without redesigning timing-critical signal paths.

FAQ
What is the maximum CAN bit rate supported by MB90F387SPMT-GS-N2E1?
The device supports CAN bit rates from 10 kbps to 1 Mbps when operating with a 16 MHz machine clock. Bit timing is configured via programmable prescaler and segment registers in the CAN controller module. Actual achievable rate depends on bus length, termination, and transceiver propagation delay-verified up to 500 kbps on 30 m twisted-pair bus with TJA1050 transceiver.
Does MB90F387SPMT-GS-N2E1 support in-system programming (ISP) via CAN or UART?
No. The device does not support ISP over CAN or UART. Programming requires parallel or serial (via dedicated programming pins) interface using Cypress's MB2145-507 emulator pod or compatible third-party programmers. Flash memory is write-protected after initial programming unless security bits are cleared via dedicated erase sequence.
How many simultaneous A/D conversions can be performed, and what triggers them?
Only one A/D conversion executes at a time, but up to eight channels can be sequenced automatically in sequential conversion mode. Conversion is triggered either by software command, internal timer overflow, or external signal on P37/ADTG pin-enabling precise synchronization with mechanical events like motor commutation or valve actuation.
What are the voltage requirements for AVcc and AVR, and can they differ from Vcc?
AVcc must be 3.5–5.5 V, same as Vcc. AVR may be set to any stable voltage ≤ AVcc (e.g., 2.5 V for 10-bit A/D full-scale of 2.5 V), but must not exceed AVcc. Decoupling capacitors (0.1 µF ceramic + 10 µF tantalum) are mandatory between AVcc–AVSS and AVR–AVSS to suppress noise affecting A/D accuracy.
