Infineon Technologies MB96F348RSAPQCR-GSE2

Overview

MB96F348RSAPQCR-GSE2 from Infineon Technologies (formerly Cypress) is a 16-bit F2MC-16FX microcontroller with dual-clock architecture, 576 KB on-chip Flash (544 KB + 32 KB), 24 KB RAM, two CAN 2.0B interfaces, 24-channel 10-bit SAR ADC, and 100-pin LQFP package. It operates at up to 56 MHz via internal PLL (x1–x25) driven by a 4 MHz external resonator, achieving 17.8 ns instruction cycle time for real-time automotive and industrial control applications.

For engineers reviewing the MB96F348RSAPQCR-GSE2 datasheet, MB96F348RSAPQCR-GSE2 pinout, MB96F348RSAPQCR-GSE2 application, or MB96F348RSAPQCR-GSE2 equivalent, key selection criteria include dual-clock domain support (main/sub), CAN protocol compliance (ISO16845), Flash security features, programmable pulse generator count (16 channels), and alarm comparator availability (2 channels).

Technical Context

The MB96F348RSAPQCR-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 supports independent frequency selection for CPU (up to 56 MHz) and peripheral domains using main oscillator (3–16 MHz), subclock (32–100 kHz), or internal RC (100 kHz/2 MHz).

Peripheral integration includes two ISO16845-certified CAN controllers (1 Mbit/s, 32 message objects each), seven full-duplex USARTs with LIN master/slave capability, four I²C channels (400 kbps), and a flexible external bus interface with six chip selects, multiplexed address/data lines, and wait-state control - all coordinated via a centralized interrupt controller with eight priority levels.

FAQ

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

The MB96F348RSAPQCR-GSE2 achieves a maximum CPU frequency of 56 MHz using its on-chip PLL, which multiplies an external 4 MHz ceramic resonator input by a factor of up to 25. This configuration delivers a 17.8 ns instruction cycle time while maintaining low EMI through integrated clock modulation and voltage regulation.

Does this MCU support ISO16845-certified CAN communication?

Yes - both CAN controllers on the MB96F348RSAPQCR-GSE2 are ISO16845 certified, ensuring conformance to CAN physical layer test requirements. Each supports bit rates up to 1 Mbit/s, 32 message objects with individual identifier masks, and programmable FIFO mode for efficient message buffering.

How does the dual-clock domain architecture benefit system design?

The dual-clock domain allows independent selection of clock sources for the CPU and two peripheral buses (CLKP1/CLKP2). This enables simultaneous high-speed computation and low-power peripheral operation - for example, running the CPU at 56 MHz while keeping RTC and alarm comparators active on a 32.768 kHz subclock during deep sleep.

What Flash security mechanisms are implemented?

The device includes hardware-enforced Flash security that prevents unauthorized read-out of ROM content. It also supports memory patching - allowing runtime replacement of ROM code sections - which facilitates embedded debugging and secure over-the-air firmware updates without exposing original binaries.
