Product details
Overview
MB90F387PMC-GTE1 from Cypress Semiconductor is a 16-bit F2MC-16LX microcontroller with integrated full-CAN interface, 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), dual 16-bit reload timers, 4-channel input capture, and low-power sleep/watch/stop modes. Used in real-time process control for consumer appliances requiring CAN-based communication and deterministic timing.
For engineers reviewing the MB90F387PMC-GTE1 datasheet, MB90F387PMC-GTE1 pinout, MB90F387PMC-GTE1 application, or MB90F387PMC-GTE1 equivalent, key selection criteria include its 16-bit CPU with 32-bit accumulator, Ver 2.0A/B CAN compliance at 10 kbps–1 Mbps, sub-clock (8.192 kHz) support for watch timer operation, and LQFP-48 package with AVCC/AVR analog power separation.
Technical Context
The MB90F387PMC-GTE1 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 PLL allows machine clock generation from 4× to 16 MHz using a 4-MHz crystal, while sub-clock operation enables ultra-low-power watch mode.
Peripheral integration includes an 8/10-bit A/D converter with 6.125 µs conversion time (at 16 MHz), one CAN controller with eight message buffers, and expanded intelligent I/O service (EI2OS) supporting up to 16 channels of autonomous data transfer - all coordinated through an 8-level, 34-source interrupt system with minimum 1.5 µs latency.

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 |
|---|---|---|---|
| MB90F387S | Same core and peripherals, but 36 I/O ports (vs. 34) and identical LQFP-48 package; no functional difference in CAN/A/D/timer subsystems | Preferred where additional GPIOs are needed for future-proofing or board layout flexibility; pin-compatible drop-in replacement | Select MB90F387S if extra I/O is required; otherwise MB90F387PMC-GTE1 offers identical performance at lower cost |
| CY8C5868LTI-LP097 | PSoC 5LP ARM Cortex-M3 with programmable analog/digital blocks; no native CAN controller - requires external CAN transceiver and firmware stack | Suitable for mixed-signal applications needing configurable logic or precision op-amps; lacks integrated CAN hardware acceleration | Choose CY8C5868LTI-LP097 only when programmable analog/digital fabric outweighs CAN performance and code size advantages of MB90F387 |
Compared with MB90F387S, the MB90F387PMC-GTE1 trades two I/O pins for marginally lower BOM cost and identical real-time CAN performance; versus CY8C5868LTI-LP097, it delivers deterministic CAN timing, smaller memory footprint, and zero-stack CAN messaging - critical for safety-critical appliance control.

FAQ
What is the maximum CAN bit rate supported by MB90F387PMC-GTE1?
The MB90F387PMC-GTE1 supports CAN bit rates from 10 kbps to 1 Mbps when operating with a 16 MHz machine clock. Bit timing registers allow precise configuration of synchronization segments, propagation time, and phase buffers to meet ISO 11898-1 requirements across bus lengths and oscillator tolerances.
Does MB90F387PMC-GTE1 require an external CAN transceiver?
Yes - the MB90F387PMC-GTE1 contains only the CAN protocol controller (CANC) and does not integrate the physical layer (PHY). An external high-speed CAN transceiver such as the TJA1042 or SN65HVD230 must be used to drive the differential CAN_H/CAN_L bus lines.
How is the 8/10-bit A/D converter configured for simultaneous sampling?
The MB90F387PMC-GTE1 does not support true simultaneous sampling across multiple channels. It performs sequential conversions with programmable inter-channel delay; however, external sample-and-hold circuitry can be synchronized to the ADTG pin (P37) to achieve pseudo-simultaneous acquisition before conversion begins.
Can MB90F387PMC-GTE1 operate from a 3.3 V supply?
No - the MB90F387PMC-GTE1 specifies a recommended operating voltage range of 3.5 V to 5.5 V. Operation below 3.5 V violates DC characteristics and may cause unstable A/D conversion, CAN timing errors, or flash programming failure. A 5 V regulator is required for reliable operation.
