Infineon Technologies MB90F352PFM-G-SNE1

Overview

MB90F352PFM-G-SNE1 from Fujitsu Semiconductor is a 16-bit F2MC-16LX microcontroller with integrated FULL-CAN interface (V2.0 A/B compliant), 128 KB Flash ROM, 4 KB RAM, and 15-channel 8/10-bit ADC. It operates at up to 24 MHz (PLL ×6 from 4 MHz crystal), delivers 42 ns instruction execution time, and targets automotive body control modules requiring CAN communication, sensor interfacing, and real-time I/O management.

For engineers reviewing the MB90F352PFM-G-SNE1 datasheet, MB90F352PFM-G-SNE1 pinout, MB90F352PFM-G-SNE1 application, or MB90F352PFM-G-SNE1 equivalent, key selection criteria include its dual-bank Flash security, 64-pin LQFP package with 49 general-purpose I/Os, CAN wake-up capability, and support for sub-clock operation via internal 100 kHz CR oscillator - critical for low-power automotive sleep modes.

Technical Context

The MB90F352PFM-G-SNE1 implements Fujitsu's F2MC-16LX CPU core with 24-bit internal addressing and a 4-byte instruction queue, enabling efficient C-language execution and multitasking. Its on-chip PLL supports selectable multiplication (×1–×6) and division (÷2) of external clock inputs, yielding machine clocks from 4 MHz to 24 MHz while maintaining 42 ns minimum instruction cycle time.

Peripheral integration includes two 16-bit freerun timers (FRT0/FRT1), six 16-bit input capture channels (ICU), four 16-bit output compare channels (OCU), two UARTs with LIN/SCI support, one I²C interface (400 kbps), and a flexible FULL-CAN controller with 16 prioritized message buffers, mailbox+FIFO mixing, and independent main/sub clock monitoring.

Manufacturer

Fujitsu Semiconductor (now part of Socionext Inc. following 2017 acquisition) is a Japanese semiconductor designer specializing in automotive, industrial, and communications ICs with emphasis on reliability and functional safety.

The MB90350 Series was developed specifically for automotive ECUs needing integrated CAN, high-precision analog sensing, and robust low-power operation - targeting ASIL-B compatible systems before ISO 26262 formalization.

FAQ

Does MB90F352PFM-G-SNE1 support CAN FD?

No. MB90F352PFM-G-SNE1 implements FULL-CAN compliant with ISO 11898-1:2003 (CAN 2.0 Part A/B), supporting up to 1 Mbps classical CAN frames only. It lacks the variable-bit-rate arbitration and extended data length features defined in CAN FD (ISO 11898-1:2015). For CAN FD, consider Socionext's newer MB96F series.

What is the purpose of the "S" suffix in MB90F352S variants?

The "S" suffix indicates absence of external sub-clock pins (X0A/X1A); these variants rely solely on the internal 100 kHz CR oscillator for sub-clock operation. MB90F352PFM-G-SNE1 does not carry the "S" suffix, confirming presence of X0A/X1A pins and compatibility with external 100 kHz crystals for higher-accuracy watch timing.

How is Flash security implemented on MB90F352PFM-G-SNE1?

Flash security is enforced via hardware lock bits that disable external read access to Flash contents and prevent unauthorized programming commands. Once enabled, the lock persists through power cycles and requires chip erase to reset - verified in DS07-13737-4E Section 12.3. This feature is exclusive to MB90F352x and MB90F357x devices.

Can MB90F352PFM-G-SNE1 operate at 125°C continuously?

Yes. As an "A-suffix" device (implied by "PFM-G-SNE1" packaging and confirmed in Product Lineup tables), MB90F352PFM-G-SNE1 supports continuous operation at 24 MHz up to +125°C ambient, meeting AEC-Q100 Grade 1 requirements. Non-A variants are limited to 16 MHz at +125°C.
