Infineon Technologies MB96F346RSAPMCR-GSE2

Overview

MB96F346RSAPMCR-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, integrated dual CAN 2.0A/B controllers, 24-channel 10-bit SAR ADC, and programmable pulse generators. It operates at up to 56 MHz CPU frequency via on-chip PLL, supports LIN/SCI/USART/I²C interfaces, and targets automotive body control and industrial real-time control systems.

For engineers reviewing the MB96F346RSAPMCR-GSE2 datasheet, MB96F346RSAPMCR-GSE2 pinout, MB96F346RSAPMCR-GSE2 application, or MB96F346RSAPMCR-GSE2 equivalent, key selection criteria include dual CAN channel support, 24-channel ADC with independent reference voltage switching, clock modulation for EMI reduction, low-voltage reset persistence, and LQFP-100 package compatibility with legacy CY96346 designs.

Technical Context

The MB96F346RSAPMCR-GSE2 implements the F2MC-16FX CPU core with instruction pipeline for RISC-like performance and full backward compatibility with 16LX software. Its clock system integrates a programmable PLL (×1–×25), dual clock domains (main/sub), and an internal 100 kHz/2 MHz RC oscillator for fast wake-up and oscillator stop detection.

Peripheral integration includes two ISO16845-certified CAN controllers (32 message objects each, FIFO mode, loop-back test), seven full-duplex USARTs with LIN master/slave capability, four I²C channels (400 kbps), and a flexible external bus interface with six chip selects and multiplexed address/data lines - all managed through dedicated peripheral buses (CLKP1/CLKP2) and DMA controller with six channels.

FAQ

What is the function of the "R" suffix in MB96F346RSAPMCR-GSE2?

The "R" suffix indicates persistent low-voltage reset (LVR) functionality - meaning the internal reset circuit remains enabled at all times and cannot be disabled by software. This ensures guaranteed brown-out protection during power fluctuations, critical for automotive and industrial safety-critical applications where unintended resets must be avoided.

Does MB96F346RSAPMCR-GSE2 support CAN FD?

No. This device implements CAN 2.0A/B protocol only, supporting bit rates up to 1 Mbit/s with ISO16845 conformance. It does not include CAN FD features such as variable bit rate, extended data length, or CRC enhancements. For CAN FD requirements, consider Infineon's newer AURIX™ or XMC™ families.

How many independent clock sources can be simultaneously active?

Three independent clock sources can operate concurrently: main oscillator (3–16 MHz), subsystem oscillator (32–100 kHz), and internal RC oscillator (100 kHz or 2 MHz). The clock & mode controller allows independent assignment of each source to CPU, peripheral bus 1, or peripheral bus 2 - enabling mixed-speed operation for power optimization.

Is external bus interface multiplexed or demultiplexed?

The external bus interface uses multiplexed address/data lines (AD0–AD15), with ALE strobe and separate RD/WR control signals. Address latching is required externally using a 74HC373 or equivalent latch. Chip select signals CS0–CS5 allow independent timing configuration per peripheral, supporting mixed-speed memory and I/O mapping.
