Product details
Overview
MB90F387SPMCR-G 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 GPIO 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 (6.125 µs conversion time), and features dual 16-bit reload timers, 16-bit input-capture timer, PPG timers, and sub-clock (8.192 kHz) wake-up capability - used in automotive body control modules requiring real-time CAN communication and mixed-signal processing.
For engineers reviewing the MB90F387SPMCR-G datasheet, MB90F387SPMCR-G pinout, MB90F387SPMCR-G application, or MB90F387SPMCR-G equivalent, key selection considerations include its LQFP-48 package, 3.5–5.5 V supply range, built-in PLL clock multiplier (1×–4×), CAN wake-up support, and compatibility with real-time OS via delay interrupt generator module.
Technical Context
The MB90F387SPMCR-G 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.
It integrates a dedicated CAN controller compliant with ISO 11898-1:2003 (CAN 2.0A/B), eight message buffers, and programmable bit timing supporting 10 kbps–1 Mbps data rates at 16 MHz machine clock. The peripheral suite includes UART (SCI) with double-buffered full-duplex operation, 8/16-bit PPG timers, and expanded intelligent I/O service (EI2OS) supporting up to 16-channel autonomous data transfer.

Pinout & Package
LQFP-48 package (0.50 mm pitch), 7 mm × 7 mm body, exposed thermal pad (not electrically connected). Pin 1 marked by dot; top-view orientation per JEDEC MS-026.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 AVcc | Analog power supply | Dedicated 5 V supply for A/D converter - must be decoupled separately from digital Vcc to minimize noise coupling |
| 2 AVR | Analog reference input | Accepts Vref+ between 0 V and AVcc; sets full-scale range for A/D conversion |
| 3–10 P50–P57 | GPIO / Analog input | Configurable as digital I/O or analog inputs AN0–AN7; require analog enable bit setting to activate A/D function |
| 11 P37 | External A/D trigger | Edge-sensitive input (rising/falling) to initiate A/D conversion - enables synchronized sampling with external events |
| 12–15 P20–P23 | Timer I/O | P20/P22 = TIN0/TIN1 (event inputs); P21/P23 = TOT0/TOT1 (programmable output pulses) - support PWM generation and event counting |

| 20–22 MD0–MD2 | Mode configuration | Hardwired Vcc/Vss during reset to select boot mode (e.g., Flash execution vs. emulator interface) |
| 23 RST | Active-low reset | Asynchronous reset input; internal pull-up ensures reliable startup without external RC network |
| 24 Vcc | Digital power supply | Main 3.5–5.5 V supply; separate from AVcc to isolate analog/digital domains |
| 40–44 P40–P44 | UART/CAN interface | P43/TX, P44/RX (SCI); P42/SOT1, P41/SCK1, P40/SIN1 (SPI-like CAN serial interface) - share pins with other peripherals |
Key Features

| Program Patch Function | Runtime address-matching detection for two pointers - supports hot-fixing of critical code sections without full reflash |
| Expanded Intelligent I/O Service (EI2OS) | Autonomous 16-channel data transfer independent of CPU - offloads sensor polling or actuator sequencing in real-time systems |
| 8/10-bit Selectable A/D Converter | Configurable resolution per channel; sequential conversion across up to 8 channels - balances precision and throughput in mixed-signal control loops |

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 GPIO (vs. 34) and identical 64 KB Flash/2 KB RAM - differs only in pinout extension for P35/P36 as X0A/X1A | Used where additional general-purpose I/O is required without changing CAN/A/D/timer functionality | Select when board layout allows LQFP-48 footprint reuse and extra I/O is needed for future expansion or debug signals |
| CY8C5868LTI-LP097 | PSoC 5LP ARM Cortex-M3 with programmable analog/digital blocks; no native CAN controller - requires external CAN transceiver and firmware stack | Preferred for designs needing mixed-signal flexibility (e.g., configurable op-amps, filters) over fixed-function CAN timing accuracy | Choose when system requires reconfigurable logic or analog front-end customization, accepting higher firmware integration effort for CAN |
Compared with MB90F387SPMCR-G, MB90F387S offers pin-compatible I/O expansion while preserving all timing-critical CAN and A/D performance; CY8C5868LTI-LP097 trades deterministic hardware CAN for FPGA-like analog/digital configurability - suitable only when CAN is secondary to signal conditioning needs.

FAQ
What is the maximum CAN bit rate supported by MB90F387SPMCR-G?
The device supports CAN bit rates from 10 kbps to 1 Mbps when operating with a 16 MHz machine clock. Bit timing is fully programmable via BTR0/BTR1 registers, allowing precise adjustment for bus length, node count, and EMI conditions - validated per ISO 11898-1:2003 conformance testing.
Does MB90F387SPMCR-G support in-system programming (ISP)?
Yes - it features on-chip 64 KB Flash ROM with ISP capability via the SCI interface or dedicated programming pins. Programming requires the MB2145-507 emulator pod and Cypress-provided tools; no external programmer hardware is needed for field firmware updates.
How many simultaneous A/D conversions can be performed?
The 8-channel A/D converter supports only one active conversion at a time, but sequential conversion mode allows automatic scanning of up to 8 channels in defined order. Each conversion takes 6.125 µs at 16 MHz, enabling full 8-channel scan in under 50 µs - sufficient for real-time motor control loop sampling.
Is the sub-clock (8.192 kHz) source internal or external?
The sub-clock is generated internally from an on-chip oscillator and does not require an external crystal. It remains active in Watch and Time-base timer standby modes, enabling wake-up from deep sleep on timer expiry or CAN message reception - critical for battery-powered nodes.
