Infineon Technologies MB96F353ASBPMC1-GSE2

Overview

MB96F353ASBPMC1-GSE2 from Fujitsu Semiconductor is a 16-bit F2MC-16FX microcontroller with 96KB Flash, 8KB RAM, 15-channel 10-bit SAR ADC, 4-channel USART (SCI/LIN), and dual-clock support (main + sub-oscillator). It operates up to 56 MHz via on-chip PLL (17.8 ns instruction cycle), features 13 low-power modes, and targets automotive body control modules requiring CAN-free, low-voltage-reset-disabled operation in LQFP-64 package.

For engineers reviewing the MB96F353ASBPMC1-GSE2 datasheet, MB96F353ASBPMC1-GSE2 pinout, MB96F353ASBPMC1-GSE2 application, or MB96F353ASBPMC1-GSE2 equivalent, key selection criteria include its no-CAN configuration (suffix "AS"), single-clock architecture, disabled low-voltage reset, 15-channel ADC resolution, and LQFP-64 thermal/mechanical compatibility for EMI-sensitive automotive PCB layouts.

Technical Context

The MB96F353ASBPMC1-GSE2 implements Fujitsu's F2MC-16FX CPU core with 23 addressing modes, barrel shift, and signed multiply/divide instructions-enabling efficient real-time control in resource-constrained systems. Its clock tree supports independent CPU and peripheral domain clocking, with internal RC oscillator (100 kHz/2 MHz) enabling safe startup and oscillator stop detection.

Peripheral integration includes four 16-bit reload timers (plus one dedicated to PPG), four free-running timers, twelve input capture units, twelve output compare units, and twenty programmable pulse generators-all synchronized to a configurable peripheral clock. The device lacks CAN interface hardware per product lineup table, confirming AS-suffix designation.

Manufacturer

Fujitsu Semiconductor (now part of Socionext Inc. following 2017 acquisition) designed high-reliability microcontrollers for automotive, industrial, and consumer applications using proprietary 0.18 µm CMOS process technology.

The MB96350 Series targets cost-sensitive, EMI-critical embedded control applications requiring deterministic real-time performance, flexible clocking, and robust low-power operation-especially where CAN is unnecessary but LIN, ADC, and PWM precision are essential.

FAQ

Does MB96F353ASBPMC1-GSE2 support CAN communication?

No. Per Fujitsu's official product lineup table, the "AS" suffix explicitly denotes "No CAN / Low voltage reset can be disabled / Single clock devices." This part lacks CAN interface hardware blocks entirely-unlike MB96F353R/F355R (1 CAN) or MB96F356Y/R (2 CAN). CAN functionality cannot be added via firmware or external peripherals.

What is the purpose of the "W" and "S" suffixes in MB96350 series part numbers?

The "W" suffix indicates dual-clock capability (main + sub-oscillator) and persistent low-voltage reset; "S" denotes single-clock operation with persistent low-voltage reset. MB96F353ASBPMC1-GSE2 uses "AS", confirming single-clock architecture and disabled low-voltage reset-critical for systems where brown-out reset must be suppressed during transient supply dips.

How does the on-chip clock modulator reduce EMI in MB96F353ASBPMC1-GSE2?

The clock modulator spreads energy across a frequency band by dithering the PLL output clock, lowering peak emissions in narrowband EMI tests. Combined with the on-chip voltage regulator that reduces internal VDD, this dual approach minimizes both conducted and radiated noise-verified in Fujitsu's EMI test reports for automotive-grade qualification.

Can the memory patch function be used for field firmware updates?

Yes. The memory patch unit allows runtime redirection of ROM fetches to RAM-mapped regions, enabling secure over-the-air or bootloader-initiated firmware patches. Fujitsu's Customer Design Review Supplement confirms this feature supports embedded debug and incremental code updates without full Flash reprogramming-subject to proper sector protection configuration.
