Infineon Technologies MB96F356RWBPMC-GSE2

Overview

MB96F356RWBPMC-GSE2 from Fujitsu Semiconductor is a 16-bit F2MC-16FX microcontroller with dual-clock architecture (main + sub-oscillator), 288KB on-chip Flash, 12KB RAM, two CAN 2.0B interfaces (ISO16845 certified), and 51 general-purpose I/O pins in 64-pin LQFP package. It operates at up to 56 MHz via internal PLL (17.8 ns instruction cycle), supports LIN master/slave, 10-bit SAR ADC (15 channels), and real-time clock with calibration - deployed in automotive body control modules and industrial motor controllers.

For engineers reviewing the MB96F356RWBPMC-GSE2 datasheet, MB96F356RWBPMC-GSE2 pinout, MB96F356RWBPMC-GSE2 application, or MB96F356RWBPMC-GSE2 equivalent, key selection criteria include dual-clock timing flexibility, CAN 2.0B compliance at 1 Mbit/s, Flash security features, 20-year data retention, and support for Time-Triggered CAN via disabled auto-retransmission mode.

Technical Context

The MB96F356RWBPMC-GSE2 implements Fujitsu's F2MC-16FX CPU core with 23 addressing modes, barrel shift, and signed multiply/divide instructions. Its clock system integrates a programmable PLL (×1–×25), 32–100 kHz sub-oscillator, and 100 kHz/2 MHz on-chip RC oscillator - enabling independent clock domains for CPU and peripherals.

Peripheral resources include two ISO16845-certified CAN controllers (32 message objects each, FIFO mode, loop-back test), four USARTs with LIN capability, one I²C interface (400 kbps), and a 15-channel 10-bit ADC with external trigger support. The device supports 13 low-power operating modes and on-chip voltage regulation for EMI reduction.

FAQ

Does MB96F356RWBPMC-GSE2 support Time-Triggered CAN (TTCAN)?

Yes. The device supports TTCAN through programmable disable of automatic retransmission on both CAN channels, allowing deterministic message scheduling. This is implemented via CAN control register bits (CMCR.CMR[1:0]) and verified in Fujitsu Application Note AN-350-002. No external transceiver modification is required.

What is the maximum allowed external clock frequency without PLL?

The maximum external clock frequency without PLL activation is 16 MHz, as specified in the "System Clock" section of the FME-MB96350 Rev.7 datasheet. Operation above 16 MHz requires PLL multiplication; ceramic resonators are limited to ≤8 MHz depending on Q-factor.

How many GPIO pins support automotive-grade Schmitt-trigger inputs?

All 51 general-purpose I/O pins support bit-wise programmable input levels, including Automotive Schmitt-trigger mode. This is configured per-pin via the PnMC register (n = port number), and validated in electrical characteristics Table 12 (VIH/VIL thresholds) of the datasheet.

Is the on-chip RC oscillator calibrated at factory?

No. The 100 kHz/2 MHz on-chip RC oscillator is uncalibrated at factory but supports runtime calibration against the sub-oscillator (X0A/X1A) using the OSCCAL register. Calibration accuracy reaches ±1% after adjustment, as confirmed in Section 5.3.2 of the datasheet.
