Infineon Technologies MB96F346RSAPQCR-GSE2

Overview

MB96F346RSAPQCR-GSE2 from Infineon Technologies (formerly Cypress) is a 16-bit F2MC-16FX microcontroller with dual-clock architecture, 416 KB Flash (Flash A), 16 KB RAM, two CAN 2.0B interfaces, 24-channel 10-bit SAR ADC, and 100-pin LQFP package. It operates up to 56 MHz via on-chip PLL (17.8 ns instruction cycle), supports LIN master/slave, I²C, seven USARTs, and real-time clock with sub-oscillator calibration - deployed in automotive body control modules and industrial CAN gateway nodes.

For engineers reviewing the MB96F346RSAPQCR-GSE2 datasheet, MB96F346RSAPQCR-GSE2 pinout, MB96F346RSAPQCR-GSE2 application, or MB96F346RSAPQCR-GSE2 equivalent, key selection criteria include dual-clock domain support (main + sub-oscillator), ISO16845-certified CAN timing compliance, flash security features, programmable pulse generator for PWM generation, and low-voltage reset persistence enabled by suffix "R".

Technical Context

The MB96F346RSAPQCR-GSE2 implements the F2MC-16FX CPU core with RISC-like pipelined execution, 23 addressing modes, and signed multiply/divide instructions. Its clock tree allows independent frequency selection for CPU (up to 56 MHz) and peripheral domains using main oscillator, 32–100 kHz sub-oscillator, or 100 kHz/2 MHz internal RC source - all selectable per domain.

Peripheral integration includes two ISO16845-certified CAN controllers (32 message objects each, loop-back/self-test mode), 24-channel ADC with dual reference voltage switching, two alarm comparators, six 16-bit reload timers (one dedicated to PPG), and external bus interface with six chip selects and multiplexed address/data lines - enabling direct connection to external SRAM or display controllers.

FAQ

What clock sources does MB96F346RSAPQCR-GSE2 support?

The MB96F346RSAPQCR-GSE2 supports three clock domains: main oscillator (3–16 MHz crystal/resonator), sub-oscillator (32–100 kHz quartz), and internal RC oscillator (100 kHz or 2 MHz). Each domain can be assigned independently to CPU or peripheral clocks, enabling flexible low-power and high-performance configurations.

Does MB96F346RSAPQCR-GSE2 support CAN FD?

No. MB96F346RSAPQCR-GSE2 implements CAN 2.0A/B protocol only, with bit rates up to 1 Mbit/s and ISO16845 physical layer certification. It does not support CAN FD data-rate acceleration or extended data length frames.

How is flash security implemented on this MCU?

Flash security uses on-chip lock bits to prevent unauthorized read-out of ROM contents via debug interfaces. The memory patch unit allows selective replacement of ROM code segments without full erase, supporting secure field updates while preserving protected bootloader sections.

What is the meaning of the "R" and "S" suffixes in MB96F346RSAPQCR-GSE2?

The "R" indicates persistent low-voltage reset (LVR) functionality that cannot be disabled in software; "S" denotes single-clock architecture (main oscillator only, no sub-oscillator). Together, they define a configuration optimized for deterministic reset behavior and simplified clocking in non-RTC applications.
