Product details
Overview
MB90F352SPFM-GS-104E1 from Fujitsu Semiconductor is a 16-bit F2MC-16LX microcontroller with integrated FULL-CAN interface (V2.0A/B), 128 KB Flash ROM, 4 KB RAM, and 64-pin LQFP package. It delivers 42 ns instruction execution time (at 24 MHz PLL clock), supports automotive-grade operation up to +125 °C, and integrates 15-channel 8/10-bit ADC, dual 16-bit freerun timers, and 2-channel UART - deployed in engine control units and body electronics.
For engineers reviewing the MB90F352SPFM-GS-104E1 datasheet, MB90F352SPFM-GS-104E1 pinout, MB90F352SPFM-GS-104E1 application, or MB90F352SPFM-GS-104E1 equivalent, key selection criteria include CAN message buffer flexibility (16 mailbox/FIFO hybrid), sub-clock independence (internal 100 kHz CR oscillator), flash security protection, dual-bank erase/write capability, and automotive voltage range (4.0–5.5 V with A/D active).
Technical Context
This MCU implements Fujitsu's proprietary F2MC-16LX core with 24-bit internal addressing and 16 MB memory space. Its on-chip PLL multiplies external 4 MHz crystal to 24 MHz (×6), enabling 42 ns instruction cycle while supporting independent main/sub-clock monitoring and stop/sleep/watch/PLL timer low-power modes.
The FULL-CAN controller features prioritized 16-message buffers with mixed mailbox/FIFO configuration, automatic retransmission, remote frame response, and acceptance filtering via full-bit compare/mask or dual partial masks - all compliant with ISO 11898-1:2003 (CAN V2.0B). Peripheral integration includes 6-channel input capture, 4-channel output compare, and EI2OS-enabled intelligent I/O service for autonomous DMA-triggered interrupt generation.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit automotive microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Renesas RL78/F13 | 16-bit CISC core; 128 KB Flash; single CAN channel; no dual-bank Flash; 10-bit ADC only | Lacks FULL-CAN message buffer flexibility and sub-clock independence; requires external crystal for all low-power modes | Select when cost-sensitive designs prioritize toolchain maturity over CAN buffer configurability and internal CR oscillator |
| NXP S12XEP100 | 16-bit HCS12X core; 128 KB Flash; dual CAN; 12-bit ADC; 56 MHz max clock; no integrated LIN | Higher performance but larger code footprint; lacks native LIN master/slave; requires external LIN transceiver | Select when dual CAN and higher-speed control loops outweigh need for integrated LIN and flash security features |
Compared with RL78/F13 and S12XEP100, MB90F352SPFM-GS-104E1 uniquely combines FULL-CAN buffer configurability, internal CR sub-clock, flash security, and LIN protocol support in a single die - reducing BOM count and simplifying functional safety validation for ASIL-B systems.

FAQ
Does MB90F352SPFM-GS-104E1 support CAN FD?
No. This device implements FULL-CAN per ISO 11898-1:2003 (CAN V2.0A/B), supporting up to 1 Mbps classical CAN frames only. It does not include CAN FD arbitration or data phase enhancements, nor does its message buffer architecture support FD frame formatting or variable bit rates.
What is the role of the 'S' suffix in MB90F352SPFM-GS-104E1?
The 'S' suffix indicates sub-clock pin omission: X0A and X1A pins are not bonded, and the internal 100 kHz CR oscillator serves as the sub-clock source. This enables watch mode operation without external crystal, reduces PCB layout complexity, and eliminates crystal-related aging/failure mechanisms in long-life automotive deployments.
How is flash security implemented on this MCU?
Flash security is enforced by hardware lock bits that disable external read access to Flash memory via debug interface or boot loader. Once enabled, protected sectors cannot be read out or reprogrammed without full chip erase. This feature is exclusive to MB90F352x variants and verified in Fujitsu DS07-13737-4E Section 12.3.
Can MB90F352SPFM-GS-104E1 operate at 24 MHz across the full −40 °C to +125 °C range?
Yes. As an 'A'-suffix derivative (implied by GS-104E1 packaging and confirmed in Product Lineup tables), it supports 24 MHz maximum machine clock at +125 °C ambient - unlike non-A variants limited to 16 MHz at that temperature. This rating assumes 4.0–5.5 V supply and proper thermal design per Fujitsu thermal guidelines.
