Infineon Technologies MB96F347RSAPQC-GSE2

Overview

MB96F347RSAPQC-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 integrated voltage regulator. It operates at up to 56 MHz via on-chip PLL (17.8 ns instruction cycle), supports LIN/USART/I²C, and targets automotive body control modules requiring ISO16845-certified CAN communication and low-EMI operation.

For engineers reviewing the MB96F347RSAPQC-GSE2 datasheet, MB96F347RSAPQC-GSE2 pinout, MB96F347RSAPQC-GSE2 application, or MB96F347RSAPQC-GSE2 equivalent, key selection criteria include dual-subsystem clocking (main + 32–100 kHz subclock), 2-channel CAN with FIFO mode and loop-back self-test, flash security and sector protection, programmable pulse generator for PWM timing, and 13 low-power operating modes including Stop and Timer wake-up.

Technical Context

The MB96F347RSAPQC-GSE2 implements the F2MC-16FX CPU core with RISC-like pipelined execution, 23 addressing modes, barrel shift, and hardware multiply/divide (16×16 signed, 32÷16). Its clock tree enables independent frequency selection for CPU (up to 56 MHz) and peripheral domains using main oscillator, subclock, or 100 kHz/2 MHz internal RC source.

Peripheral integration includes two ISO16845-certified CAN controllers (32 message objects each, bit rates up to 1 Mbit/s), seven full-duplex USARTs with LIN master/slave support, four I²C channels (400 kbps), and a 24-channel ADC with dual reference voltage switching (AVRH/AVRL or AVRH2). The device uses 0.18 µm CMOS technology and features on-chip clock modulation and voltage regulation for EMI suppression.

FAQ

What clock sources does MB96F347RSAPQC-GSE2 support?

The MB96F347RSAPQC-GSE2 supports three primary clock sources: an external 3–16 MHz crystal/resonator on X0/X1, a 32–100 kHz subclock quartz on X0A/X1A, and an internal 100 kHz/2 MHz RC oscillator. The PLL can multiply any of these to generate up to 56 MHz for the CPU, while peripheral clocks may be independently derived from main, sub, or RC sources.

Does MB96F347RSAPQC-GSE2 support AEC-Q100 qualification?

Yes-MB96F347RSAPQC-GSE2 is qualified to AEC-Q100 Grade 2 (−40 °C to +105 °C ambient) per Infineon's official product documentation and ordering information. This includes stress testing for temperature cycling, humidity bias, and ESD robustness required for under-hood and cabin automotive applications.

How is Flash security implemented on this MCU?

Flash security is enforced via hardware lock bits that disable external read access to ROM/Flash contents through JTAG or serial programming interfaces. Once enabled, the lock prevents firmware extraction and requires full chip erase to reset-supporting IP protection and anti-tampering requirements in production ECUs.

Can MB96F347RSAPQC-GSE2 operate without an external crystal?

Yes-the device can boot and run entirely from its internal 100 kHz or 2 MHz RC oscillator, enabling rapid startup and crystal-free operation in non-timing-critical subsystems. However, CAN, LIN, and high-accuracy RTC functions require either the main or subclock oscillator for compliance with protocol timing tolerances.
