Product details
Overview
MB90F352SPFM-GS-102E1 from Fujitsu Semiconductor is a 16-bit F2MC-16LX microcontroller with integrated FULL-CAN interface (V2.0 Part A/B), 128 KB on-chip Flash ROM, 4 KB RAM, and operation up to 24 MHz at +125 °C. It features dual-bank Flash for concurrent read/erase/write, 15-channel 8/10-bit ADC (3 µs conversion), and 2× 16-bit freerun timers - deployed in automotive body control modules requiring real-time CAN messaging and sensor interfacing.
For engineers reviewing the MB90F352SPFM-GS-102E1 datasheet, MB90F352SPFM-GS-102E1 pinout, MB90F352SPFM-GS-102E1 application, or MB90F352SPFM-GS-102E1 equivalent, key selection criteria include CAN message buffer flexibility (16 prioritized mailboxes), sub-clock independence (100 kHz internal CR oscillator), PLL-based 42 ns instruction execution, and Flash security protection - all validated for AEC-Q100-compliant automotive ECU designs.
Technical Context
This MCU implements the F2MC-16LX CPU core with 24-bit internal addressing and 16 Mbyte memory space, supporting bit/byte/word/long-word data types and 23 addressing modes optimized for embedded control. Its clock system integrates a programmable PLL (×1–×6 or ÷2), independent main/sub-clock monitoring, and low-power modes including Sleep, Stop, Watch, and PLL Timer modes.
The peripheral set includes two UARTs (LIN/SCI capable), one I²C interface (400 kbps), 4-channel output compare, 6-channel input capture, and a FULL-CAN controller with automatic retransmission, remote frame response, and flexible acceptance filtering (full-bit mask or dual partial masks). The 15-channel ADC supports external trigger activation and selectable 8-/10-bit resolution.

Key Features
| Feature | Design Value |
|---|---|
| Flash Security Function | Hardware-enforced read/write protection of Flash contents - prevents unauthorized firmware extraction or overwrite |
| Flexible CAN Message Buffering | Mixed mailbox/FIFO configuration allows simultaneous handling of high-priority event frames and periodic status messages |
| Sub-Clock Independence | Internal 100 kHz CR oscillator enables watchdog and wake-up timing without external crystal - reduces BOM cost and board area |
| Dual-Bank Flash Architecture | Enables background firmware update: new code writes to upper bank while lower bank executes active application |
| Extended Intelligent I/O Service (EI2OS) | 16-channel DMA-assisted I/O event handling offloads CPU during high-frequency sensor polling or PWM synchronization |

FAQ
Does MB90F352SPFM-GS-102E1 support CAN FD?
No. This device implements only FULL-CAN compliant with ISO 11898-1 V2.0 Part A and Part B, supporting data rates up to 1 Mbps. It lacks CAN FD's variable bit rate, extended data length, and CRC enhancements. For CAN FD requirements, consider Socionext's RH850/F1L or RA6T2-based solutions.
What is the purpose of the 'S' suffix in MB90F352S?
The 'S' suffix indicates absence of external sub-clock pins (X0A/X1A); instead, the device uses an internal 100 kHz CR oscillator for watch timer and low-power mode timing. This reduces external component count and PCB footprint but removes option for precision external sub-clock source.
How does dual-bank Flash operation work in practice?
Dual-bank Flash allows erasing/writing one bank (e.g., Upper Bank) while executing code from the other (Lower Bank). During firmware update, the bootloader copies new code to the inactive bank, validates checksum, then switches vector table address - enabling zero-downtime field updates without halting real-time CAN messaging.
Is MB90F352SPFM-GS-102E1 qualified to AEC-Q100?
Yes. As an A-suffix device rated for −40 °C to +125 °C operation and manufactured using Fujitsu's automotive-grade process, MB90F352SPFM-GS-102E1 meets AEC-Q100 Grade 1 stress testing requirements - confirmed in Fujitsu's official qualification reports for the MB90350 Series.
