Infineon Technologies MB96F347RSAPQCR-GS-ERE2

Overview

MB96F347RSAPQCR-GS-ERE2 from Infineon Technologies (formerly Cypress) is a 16-bit F2MC-16FX microcontroller with dual-clock architecture, 544 KB on-chip Flash, 24 KB RAM, integrated dual CAN 2.0A/B controllers (ISO16845 certified), 24-channel 10-bit SAR ADC, and programmable pulse generators. It operates at up to 56 MHz CPU frequency (17.8 ns instruction cycle) using an internal PLL driven by a 4 MHz external resonator, targeting automotive body control modules and industrial real-time communication nodes.

For engineers reviewing the MB96F347RSAPQCR-GS-ERE2 datasheet, MB96F347RSAPQCR-GS-ERE2 pinout, MB96F347RSAPQCR-GS-ERE2 application, or MB96F347RSAPQCR-GS-ERE2 equivalent, key selection criteria include dual-CAN timing determinism, Flash sector protection for OTA updates, subclock RTC calibration, alarm comparator thresholds, and 100-pin LQFP package compatibility with legacy CY96F34x designs.

Technical Context

The MB96F347RSAPQCR-GS-ERE2 implements the F2MC-16FX CPU core with RISC-like pipelined execution, 23 addressing modes, and hardware-signed multiply/divide. Its clock tree supports independent domain selection: CPU from PLL-multiplied main clock (up to 56 MHz), peripherals from main/sub/RC oscillators, and RTC from 32–100 kHz quartz.

It integrates two ISO16845-certified CAN controllers supporting bit rates up to 1 Mbit/s, 32 message objects each with individual identifier masks, FIFO concatenation, and loop-back self-test mode. The 24-channel ADC features dual reference voltage switching (AVRH/AVRL or AVRH2), interrupt-on-conversion, and external trigger capability via reload timers.

FAQ

What clock sources does MB96F347RSAPQCR-GS-ERE2 support for the CPU and peripherals?

The CPU can be clocked from the internal PLL (multiplied from 4 MHz external resonator to 56 MHz), 3–16 MHz external crystal, or 100 kHz/2 MHz on-chip RC oscillator. Peripherals operate from independently selectable clocks: main oscillator, sub-oscillator (32–100 kHz), or RC oscillator-enabling low-power RTC operation while CPU sleeps.

How is Flash security implemented on this MCU?

Flash security uses a dedicated lock-bit mechanism that disables external read-out via serial programming interface. Once enabled, ROM content cannot be accessed externally; memory patch function remains available for in-system debug but requires unlock sequence. Sector protection allows write/erase locking of individual 2 KB Flash blocks.

Does MB96F347RSAPQCR-GS-ERE2 support CAN FD or only classical CAN?

This device supports only Classical CAN (ISO 11898-1:2015, CAN 2.0A/B), not CAN FD. It implements two fully compliant CAN 2.0B controllers certified to ISO 16845 test suites, with bit rates up to 1 Mbit/s, 32 message objects per channel, and programmable FIFO modes-but lacks CAN FD's extended data length and bit rate switching.

What is the role of the alarm comparator in system-level design?

The dual-channel alarm comparator monitors external analog voltages (e.g., battery supply or sensor bias rails) against programmable upper/lower thresholds. It generates an interrupt within <1 µs without CPU intervention-enabling immediate shutdown, logging, or fail-safe state transition in safety-critical applications like power distribution or battery management.
