Infineon Technologies MB96F347RSBPQC-GSE2

Overview

MB96F347RSBPQC-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 2.0B interfaces, 24-channel 10-bit SAR ADC, and 16-bit programmable pulse generators. It operates up to 56 MHz via on-chip PLL (17.8 ns instruction cycle), supports LIN/SCI/USART/I²C, and targets automotive body control modules requiring deterministic real-time response and EMI-optimized clock modulation.

For engineers reviewing the MB96F347RSBPQC-GSE2 datasheet, MB96F347RSBPQC-GSE2 pinout, MB96F347RSBPQC-GSE2 application, or MB96F347RSBPQC-GSE2 equivalent, key selection criteria include dual-clock domain support (main + sub-oscillator), 2× ISO16845-certified CAN channels with FIFO mode and loop-back self-test, flash security and memory patch capability, and low-voltage reset persistence in single-clock configuration (suffix "S").

Technical Context

The MB96F347RSBPQC-GSE2 implements the F2MC-16FX CPU core with RISC-like pipelined execution, 23 addressing modes, barrel shift, and signed multiply/divide instructions. Its clock tree enables independent frequency scaling for CPU (up to 56 MHz) and peripherals using main oscillator, 32–100 kHz sub-oscillator, or 100 kHz/2 MHz internal RC source - all selectable per domain.

System-level features include 16-channel DMA, 12-input-capture/12-output-compare units, 20-channel PPG with PWM/one-shot modes, and alarm comparators with external threshold inputs. The device integrates an on-chip voltage regulator for reduced internal VDD and EMI suppression, plus clock modulation to flatten spectral emission peaks.

FAQ

What is the maximum operating frequency and how is it achieved?

The MB96F347RSBPQC-GSE2 achieves a maximum CPU frequency of 56 MHz using its integrated PLL with multiplication factors from x1 to x25. An external 4 MHz ceramic resonator is sufficient to generate this clock, eliminating need for higher-frequency crystals. The PLL lock time is specified at ≤100 µs, and the resulting 17.8 ns instruction cycle enables deterministic real-time response in safety-critical loops.

Does this MCU support AEC-Q100 qualification and what grade applies?

Yes, the MB96F347RSBPQC-GSE2 is qualified to AEC-Q100 Grade 2 (−40 °C to +105 °C ambient), verified per Infineon's automotive qualification program. This includes stress testing for HTOL, TCT, ESD, and latch-up, with full documentation traceable to Infineon's QM-00101 automotive quality manual and test reports available upon request.

How does the memory patch function operate and what are its use cases?

The memory patch function redirects ROM address accesses to RAM-mapped locations during runtime, enabling dynamic replacement of firmware routines without erasing Flash. It is used for field calibration updates, hotfix deployment, and embedded JTAG/SWD debug stub injection - all while preserving original Flash contents and maintaining secure boot integrity.

Can the dual CAN interfaces operate simultaneously at different bit rates?

Yes, each CAN controller (CAN0 and CAN1) has independent bit-timing registers and clock dividers, allowing concurrent operation at distinct bit rates - e.g., CAN0 at 500 kbit/s for body network and CAN1 at 1 Mbit/s for powertrain diagnostics. Both support ISO16845 conformance testing and share no timing resource conflicts.
