Product details
Overview
MB90F387SPMT-GS 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 from 3.5 V to 5.5 V, supports PLL clock multiplication (4–16 MHz), and delivers 62.5 ns minimum instruction execution time at 16 MHz - enabling real-time control in automotive body electronics and industrial PLCs.
For engineers reviewing the MB90F387SPMT-GS datasheet, MB90F387SPMT-GS pinout, MB90F387SPMT-GS application, or MB90F387SPMT-GS equivalent, key selection criteria include its full-CAN interface with 8 message buffers, 8/10-bit 8-channel ADC (6.125 µs conversion), dual 16-bit reload timers, and low-power sleep/watch modes - all in LQFP-48 package with verified pin mapping.
Technical Context
The MB90F387SPMT-GS implements the F2MC-16LX architecture with 24-bit internal addressing, 32-bit accumulator for long-word arithmetic, and 351 instructions supporting bit/byte/word/long-word data types across 23 addressing modes. Its instruction set includes enhanced multiply-divide, barrel shift, and RETI instructions optimized for C-language compilation and multitasking RTOS use.
Peripheral integration includes one CAN controller compliant with ISO 11898-1:2003, one UART (SCI) with full-duplex double buffer and clock-sync/asynchronous modes, four external interrupt inputs (INT4–INT7), and an expanded intelligent I/O service (EI2OS) supporting up to 16 channels - all managed via dedicated interrupt vectors with 8 priority levels and 34 interrupt sources.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | F2MC-16LX 16-bit RISC with 32-bit accumulator and 24-bit addressing space |
| Flash ROM / RAM | 64 KB on-chip Flash (programmable in-system), 2 KB SRAM - sufficient for standalone CAN node firmware with ADC-based sensor polling |
| CAN Interface | Single-channel CAN 2.0A/B controller with 8 message buffers and 10 kbps–1 Mbps rate - supports wake-up on bus activity |
| ADC | 8-channel 8/10-bit selectable A/D converter; 6.125 µs conversion time at 16 MHz - enables fast sampling of analog sensors (e.g., temperature, pressure) |
| Timers | One 16-bit free-run timer, four 16-bit input capture units (ICU), two 16-bit reload timers, one 18-bit time-base timer - supports precise PWM generation and event timing |
| Package & Power | LQFP-48 (0.5 mm pitch); 3.5–5.5 V operation; five low-power modes (Sleep, Watch, Time-base timer, Stop, CPU blocking) |
| I/O Ports | 34 CMOS I/O pins including P14–P17 as 4 high-current outputs (20 mA sink/source) - suitable for direct LED or small relay drive |
Pinout & Package
LQFP-48 package (0.5 mm pitch), 7 mm × 7 mm body, exposed thermal pad - compatible with standard reflow profiles and automated PCB assembly.
| 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 maintain 10-bit accuracy |
| 2 AVR | Analog reference input | Accepts external Vref+ (≤ Vcc); sets full-scale range for ADC - enables ratiometric sensor measurements |
| 3–10 P50–P57 | Multi-function I/O / ADC inputs | Configurable as digital I/O or analog inputs AN0–AN7 - requires software enable of analog function before ADC use |
| 11 P37 | External ADC trigger | Edge-sensitive input (rising/falling) to initiate conversion - synchronizes sampling with mechanical or electrical events |
| 12 P20 / 14 P22 | Reload timer input | TIN0/TIN1 accept external pulses for event counting or gated timing - used in motor RPM measurement or pulse-width analysis |
| 13 P21 / 15 P23 | Reload timer output | TOT0/TOT1 generate programmable-width pulses - directly drives gate drivers or indicator strobes without CPU intervention |
| 16–19 P24–P27 | External interrupt inputs | INT4–INT7 support level- or edge-triggered interrupts - used for emergency stop, limit switch, or CAN error signaling |
| 23 RST | Active-low reset | Asynchronous reset input; internal pull-up ensures reliable startup - requires ≥100 ns pulse width for valid reset assertion |
| 24 Vcc | Digital power supply | Main 3.5–5.5 V supply; decoupling capacitor required within 10 mm of pin to suppress switching noise |
| 40–43 P40–P43 | SCI interface | SIN1/SCK1/SOT1/RX support synchronous master/slave or asynchronous UART - enables debug logging or host MCU communication |
| 47–48 X0/X1 | Crystal oscillator inputs | Supports 4 MHz fundamental-mode crystal; internal PLL multiplies to 16 MHz - eliminates need for external clock generator |
Key Features
| Feature | Design Value |
|---|---|
| Full-CAN 2.0A/B Controller | Hardware-accelerated CAN protocol handling with automatic ID filtering, error confinement, and bus-off recovery - reduces CPU load by >70% vs. software-implemented CAN |
| 8/10-bit 8-Channel ADC | Selectable resolution and sequential conversion mode - allows simultaneous monitoring of multiple analog sensors (e.g., cabin temp, battery voltage, pedal position) with single trigger |
| Expanded Intelligent I/O (EI2OS) | 16-channel DMA-like peripheral service - offloads repetitive I/O tasks (e.g., LED matrix scanning, keypad polling) from CPU, freeing cycles for CAN message processing |
| Low-Power Watch Mode | Sub-clock (8.192 kHz) + watch timer only active - draws <10 µA while maintaining real-time wake capability for periodic CAN bus monitoring |
| Program Patch Function | Runtime address-matching detection for two pointers - enables field-upgradable firmware patches without full reflash, critical for automotive ECU compliance |
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 |
|---|---|---|---|
| Infineon XC2267M | TriCore 32-bit core, 256 KB Flash, dual CAN channels, but no built-in 10-bit ADC - requires external SAR converter | Targeted at higher-end automotive powertrain; lacks integrated analog front-end for cost-sensitive body electronics | Choose when 32-bit performance and dual CAN are mandatory; avoid if analog integration and BOM simplicity are priorities |
| Renesas RL78/F13 | 16-bit core, 128 KB Flash, single CAN, 10-bit 24-channel ADC, but slower max clock (32 MHz) and no EI2OS peripheral | Optimized for ultra-low-power consumer appliances; lacks hardware-accelerated I/O offload for high-frequency polling | Choose for sub-100 µA standby designs with heavy analog channel count; avoid when deterministic I/O servicing is required |
Compared with XC2267M and RL78/F13, MB90F387SPMT-GS uniquely balances CAN 2.0B compliance, integrated 10-bit ADC, EI2OS-driven I/O efficiency, and 62.5 ns instruction timing - making it optimal for cost-constrained, real-time automotive and industrial nodes where mixed-signal integration reduces system complexity.

FAQ
Is MB90F387SPMT-GS pin-compatible with other MB90385-series devices?
Yes - MB90F387SPMT-GS shares identical LQFP-48 pinout with MB90F387, MB90387, and MB90387S variants. Differences are limited to ROM type (Flash vs. mask), RAM size, and minor I/O count (34 vs. 36 ports), all electrically and physically compatible at the package level.
Does MB90F387SPMT-GS 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 or extended payload. It supports bit rates up to 1 Mbps with standard 8-byte frames only.
What is the maximum operating frequency of the internal PLL?
The PLL multiplies the external crystal input (e.g., 4 MHz) by factors of 1× to 4×, yielding machine clock frequencies from 4 MHz to 16 MHz. At 16 MHz, the minimum instruction execution time is 62.5 ns - confirmed in the datasheet's AC characteristics table (Rev. *A, p.60).
Can the 8/10-bit ADC operate in differential mode?
No - the ADC supports only single-ended analog inputs on P50–P57 (AN0–AN7). Differential input capability is not implemented; each channel measures voltage relative to AVSS (pin 48), and no programmable gain amplifier or differential pair routing is provided in the analog front-end.
