Infineon Technologies MB96F347RSBPMC-GSE2

Overview

MB96F347RSBPMC-GSE2 from Infineon Technologies (formerly Cypress) is a 16-bit F2MC-16FX microcontroller with dual-clock architecture, 544 KB Flash, 24 KB RAM, two CAN 2.0A/B controllers (ISO16845 certified), 24-channel 10-bit SAR ADC, and 2-channel alarm comparator. It operates at up to 56 MHz CPU frequency via internal PLL (x25 multiplier from 4 MHz resonator), achieves 17.8 ns instruction cycle time, and supports 13 low-power operating modes. Used in automotive body control modules requiring real-time CAN communication and analog sensor interfacing.

For engineers reviewing the MB96F347RSBPMC-GSE2 datasheet, MB96F347RSBPMC-GSE2 pinout, MB96F347RSBPMC-GSE2 application, or MB96F347RSBPMC-GSE2 equivalent, key selection criteria include dual-clock domain support (main/sub), 2× CAN channels with programmable FIFO and loop-back test mode, Flash security and patching capability, and EMI-optimized clock modulation with on-chip voltage regulator.

Technical Context

The MB96F347RSBPMC-GSE2 implements the F2MC-16FX CPU core with RISC-like pipelined execution, 23 addressing modes, barrel shift, and hardware signed multiply/divide (16×16/32÷16). Its clock tree enables independent frequency selection for CPU (up to 56 MHz) and peripheral domains using main oscillator (3–16 MHz), subclock (32–100 kHz), or 100 kHz/2 MHz internal RC oscillator.

Peripheral integration includes two ISO16845-certified CAN controllers supporting bit rates up to 1 Mbit/s, 7 full-duplex USARTs with LIN master/slave capability, four I²C interfaces (400 kbps), and a flexible external bus interface with 6 chip selects, multiplexed address/data lines, and wait-state control - all managed via dedicated clock domains and interrupt controller with 8 priority levels.

FAQ

What is the maximum operating frequency of the MB96F347RSBPMC-GSE2 CPU core?

The CPU core runs at up to 56 MHz using the internal PLL with a 4 MHz external resonator (25× multiplication). This yields a minimum instruction cycle time of 17.8 ns. The PLL supports selectable multipliers from ×1 to ×25, and the core remains functional at lower frequencies for power-sensitive applications.

Does MB96F347RSBPMC-GSE2 support LIN communication?

Yes - it integrates seven full-duplex USARTs with dedicated LIN functionality, supporting both master and slave roles. Each LIN-capable channel includes break detection, sync field handling, and checksum generation per LIN 2.x specifications, with baud rate programmability via reload timers.

How is Flash memory protected against unauthorized access?

Flash security is enforced through a dedicated lock-bit mechanism that disables external read-out via serial programming interface. Once enabled, ROM content cannot be extracted; memory patching remains functional for authorized firmware updates, and security status is verified at boot via Boot ROM checks.

Can the MB96F347RSBPMC-GSE2 operate without an external crystal?

Yes - it includes a factory-trimmed 100 kHz/2 MHz internal RC oscillator for immediate startup and watchdog operation. This allows full functionality in crystal-less configurations, though CAN timing accuracy and ADC reference stability require external crystal or resonator for production-grade compliance.
