Infineon Technologies MB96F346RWAPMC-GSE2

Overview

MB96F346RWAPMC-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 (17.8 ns instruction cycle) using an on-chip PLL driven by a 4 MHz external resonator, and supports automotive-grade I/O with Schmitt-trigger inputs and configurable drive strength. It is deployed in body control modules requiring real-time CAN communication, sensor acquisition, and deterministic timing.

For engineers reviewing the MB96F346RWAPMC-GSE2 datasheet, MB96F346RWAPMC-GSE2 pinout, MB96F346RWAPMC-GSE2 application, or MB96F346RWAPMC-GSE2 equivalent, key selection criteria include dual-clock domain support (main + subclock), ISO16845-certified CAN compliance, 2-channel alarm comparator for voltage monitoring, flash security features, and 100-pin LQFP package compatibility with legacy CY96346 designs.

Technical Context

The MB96F346RWAPMC-GSE2 implements the F2MC-16FX CPU core with 23 addressing modes, barrel shift, signed multiply/divide instructions, and an 8-byte instruction queue - enabling RISC-like performance while maintaining software compatibility with 16LX-series firmware. Its clock tree supports independent selection of CPU and peripheral clock sources: main oscillator (3–16 MHz), sub-oscillator (32–100 kHz), or internal RC (100 kHz/2 MHz), with PLL multiplication (×1 to ×25) enabling 56 MHz operation from low-frequency crystals.

Peripheral integration includes two ISO16845-certified CAN controllers (32 message objects each, loop-back/self-test mode), seven full-duplex USARTs with LIN master/slave capability, four I²C channels (400 kbps), and a flexible timer subsystem comprising 4 × 16-bit free-running timers, 8 × 16-bit output compare units, 8 × 16-bit input capture units, and 16 × 16-bit programmable pulse generators - all synchronized to configurable clock domains.

FAQ

What is the purpose of the "RW" suffix in MB96F346RWAPMC-GSE2?

The "RW" suffix indicates dual-clock capability (main + sub-oscillator) and configurable low-voltage reset behavior - specifically, the ability to disable the low-voltage reset function. This enables flexible power management in systems where brown-out detection must be handled externally or selectively enabled during specific operational phases.

Does MB96F346RWAPMC-GSE2 support LIN 2.2 protocol natively?

Yes - it integrates full-duplex USARTs with hardware LIN functionality supporting both master and slave roles, including automatic sync-break detection, checksum calculation, and identifier filtering. The LIN peripheral operates independently of CAN and can share pins with SCI or UART functions via multiplexing.

How many CAN message objects are supported, and are they shared between CAN channels?

Each of the two CAN controllers supports 32 dedicated message objects with individual identifier masks and FIFO configuration. Message objects are not shared - each channel has its own 32-object RAM buffer, enabling concurrent handling of separate CAN buses (e.g., comfort and chassis networks) without resource contention.

Is the internal RC oscillator accurate enough for RTC operation?

No - the internal RC oscillator (100 kHz/2 MHz) is intended for fast wake-up and safe startup only. For RTC operation, the part requires connection to a 32.768 kHz quartz on X0A/X1A pins. However, the RTC includes clock calibration circuitry to correct sub-oscillator drift, achieving ±1 ppm accuracy after calibration.
