Product details
Overview
MB90F387SPMT-GS-9003 from 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 general-purpose I/O 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, and features dual 16-bit reload timers, 4-channel input capture, and sub-clock (8.192 kHz) real-time operation - deployed in automotive body control modules requiring deterministic CAN messaging and mixed-signal processing.
For engineers reviewing the MB90F387SPMT-GS-9003 datasheet, MB90F387SPMT-GS-9003 pinout, MB90F387SPMT-GS-9003 application, or MB90F387SPMT-GS-9003 equivalent, key selection criteria include its full-CAN interface compliance, 34-pin LQFP-48 package with AVCC/AVR analog power separation, Flash-based field programmability, low-power sleep/watch modes, and native 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 spanning 8- and 16-bit encodings. Its interrupt subsystem delivers 34 sources across 8 priority levels, with hardware-accelerated EI2OS for intelligent I/O servicing across up to 16 channels.
The peripheral set includes a UART (SCI) with full-duplex double buffering, 8/16-bit PPG timer configurable as four 8-bit or two 16-bit pulse generators, and a dedicated delay interrupt generator for RTOS task switching. All timing peripherals - including 18-bit time-base timer and 15-bit watch timer - are synchronized to either main oscillator (4–16 MHz) or sub-clock (8.192 kHz).

Pinout & Package
LQFP-48 package (pin pitch 0.50 mm), thermally optimized for industrial ambient (–40°C to +85°C) and automotive-grade reliability. Pin 1 marked by corner notch; exposed thermal pad not electrically connected.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 AVcc | Analog VCC supply | Dedicated 3.5–5.5 V power rail for A/D converter core - must be decoupled separately from digital Vcc |
| 2 AVR | Analog reference input | Accepts external VREF+ ≤ VCC; enables ratiometric measurement when tied to AVcc or precision voltage source |
| 3–10 P50–P57 | Port 5 I/O + AN0–AN7 | Shared digital I/O and analog inputs; ANx pins active only when analog mode enabled in ADCTL register |
| 11 P37/ADTG | External A/D trigger | Edge-sensitive input that initiates conversion sequence without CPU intervention - critical for synchronized sensor sampling |
| 12–15 P20–P23 | TIN0/TOT0/TIN1/TOT1 | Timer event I/O: TINx captures external edges for reload timer gating; TOTx outputs PWM or pulse-width modulated signals |
| 16–19 P24–P27 | INT4–INT7 | Dedicated external interrupt inputs with configurable edge/level sensitivity - used for wake-up or fast response to safety-critical events |
| 20–22 MD2–MD0 | Mode configuration | Hardwired boot-mode select: MD2=Vss, MD1=Vcc, MD0=Vcc sets standard Flash execution mode |
| 23 RST | Active-low reset | Asynchronous reset input; internal pull-up ensures safe startup; compatible with RC or supervisor IC reset circuits |
| 24 Vcc | Digital power supply | Main 3.5–5.5 V supply for CPU and digital peripherals - requires local 0.1 µF ceramic decoupling |
| 40–44 P40–P44 | SIN1/SCK1/SOT1/TX/RX | SCI serial interface: full-duplex UART with synchronous (SPI-like) and asynchronous (RS-232-like) modes |
Key Features
| Feature | Design Value |
|---|---|
| Full-CAN 2.0A/B Controller | Hardware-accelerated message filtering, transmission arbitration, and error handling - eliminates software overhead in bus-heavy applications |
| Program Patch Function | Runtime address-matching detection for two pointers enables hot-patching of critical firmware sections without full reflash |
| Expanded Intelligent I/O Service (EI2OS) | Offloads CPU for up to 16-channel I/O event handling - supports debounced GPIO, pulse counting, and pattern matching |
| Low-Power Mode Flexibility | Five distinct standby modes (Sleep, Watch, Time-base timer, Stop, CPU blocking) with sub-clock retention - extends battery life in always-on nodes |
| C-Language Optimization | System stack pointer, barrel shift, and enhanced pointer-indirect instructions reduce compiled C code size and improve RTOS compatibility |
Applications

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 change in CAN/A/D/timer resources | Preferred where additional GPIO is needed for status LEDs or auxiliary sensors without board redesign | Select MB90F387S if extra I/O is required; pin-compatible and drop-in replaceable in existing layouts |
| CY8C5868LTI-LP097 | PSoC 5LP ARM Cortex-M3 with programmable analog/digital blocks; no native CAN controller - requires external transceiver and firmware-implemented CAN protocol stack | Used where mixed-signal flexibility (e.g., custom op-amp configurations, CapSense) outweighs CAN hardware acceleration needs | Choose CY8C5868LTI-LP097 only when programmable analog/digital fabric justifies added software complexity and validation effort |
Compared with MB90F387SPMT-GS-9003, MB90F387S offers identical CAN performance with two extra GPIOs, while CY8C5868LTI-LP097 trades hardware CAN offload for configurable analog resources - making the former ideal for cost-sensitive CAN-centric designs and the latter better suited for multi-function sensor hubs.

FAQ
Does MB90F387SPMT-GS-9003 support CAN FD?
No. The integrated CAN controller complies strictly with ISO 11898-1:2003 (CAN 2.0A/B) and does not implement CAN FD features such as flexible data-rate, extended data length, or CRC enhancements. It supports bit rates from 10 kbps to 1 Mbps using standard 11- or 29-bit identifiers.
What is the maximum operating temperature range for this device?
The MB90F387SPMT-GS-9003 is rated for industrial operation from –40°C to +85°C ambient temperature. This rating is validated per JEDEC JESD22-A108 and applies to continuous operation under specified Vcc (3.5–5.5 V) and load conditions.
Can the 8/10-bit A/D converter perform simultaneous sampling across multiple channels?
No. The SAR ADC performs sequential conversions only - even in "sequential conversion mode," channels are sampled one after another. True simultaneous sampling requires external analog front-end hardware; the internal design uses a single sample-and-hold circuit shared across all eight ANx inputs.
Is there an official programming tool supported for Flash programming in-system?
Yes. Cypress provides the MB2145-507 emulation pod with配套 software (e.g., Cypress Programmer Suite) for in-circuit Flash programming via the on-chip debug interface. Programming requires connection to the RST, MD0–MD2, and Vcc pins - no external bootloader is needed.
