Infineon Technologies MB96F346RSBPMC-GSE2

Overview

MB96F346RSBPMC-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 2.0A/B controllers, 24-channel 10-bit SAR ADC, and integrated voltage regulator. 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, targeting automotive body control, industrial PLC I/O modules, and CAN-based gateway applications.

For engineers reviewing the MB96F346RSBPMC-GSE2 datasheet, MB96F346RSBPMC-GSE2 pinout, MB96F346RSBPMC-GSE2 application, or MB96F346RSBPMC-GSE2 equivalent, key selection criteria include dual-clock domain support (main + subclock), ISO16845-certified CAN timing compliance, 2-channel CAN with 32 message objects per channel, flash security lock, and programmable pulse generator for motor control PWM generation.

Technical Context

The MB96F346RSBPMC-GSE2 implements the F2MC-16FX CPU core with RISC-like pipelined execution, 23 addressing modes, and native 16×16 signed multiply/32÷16 divide instructions. Its clock system supports independent domain selection: CPU from PLL-multiplied main clock (up to 56 MHz), peripherals from main clock, subclock (32–100 kHz), or internal RC oscillator (100 kHz/2 MHz).

Peripheral integration includes two ISO16845-certified CAN controllers (bit rates up to 1 Mbit/s), seven full-duplex USARTs with LIN master/slave capability, four I²C channels (400 kbps), and a 24-channel 10-bit ADC with dual reference voltage switching (AVRH/AVRL or AVRH2). The device features 13 low-power operating modes and on-chip clock modulation for EMI reduction.

Key Specifications

Pinout & Package

MB96F346RSBPMC-GSE2 is housed in a 100-pin LQFP package (14 mm × 14 mm, 0.5 mm pitch) with exposed thermal pad. Pin functions are defined across five I/O ports (P0–P4), dual CAN transceiver interfaces (CAN0TX/CAN0RX, CAN1TX/CAN1RX), dual clock inputs (X0/X1, X0A/X1A), and dedicated analog supply pins (AVCC/AVSS/AVRH/AVRL).

FAQ

What clock sources does MB96F346RSBPMC-GSE2 support for the CPU and peripherals?

The MB96F346RSBPMC-GSE2 supports three independent clock sources: a main oscillator (3–16 MHz crystal/resonator), a subclock (32–100 kHz quartz), and an internal RC oscillator (100 kHz/2 MHz). The CPU clock is selectable from PLL-multiplied main clock (up to 56 MHz) or RC oscillator; peripherals can be assigned to main, sub, or RC clocks independently via the clock tree register set.

Does MB96F346RSBPMC-GSE2 support CAN FD or only classical CAN 2.0?

MB96F346RSBPMC-GSE2 supports only Classical CAN 2.0 Part A and B (ISO 11898-1:2003), with bit rates up to 1 Mbit/s and ISO16845 physical-layer certification. It does not implement CAN FD frame format, data-rate switching, or extended data length. For CAN FD, Infineon's TRAVEO™ T2G or AURIX™ families are recommended alternatives.

How is flash security implemented on MB96F346RSBPMC-GSE2?

Flash security is enforced via hardware lock bits that disable external read access to Flash memory through the serial programming interface. Once enabled, ROM content cannot be extracted via standard debug or programming tools. Security activation is irreversible and must be performed during final firmware programming. No software-only unlock mechanism exists - physical reprogramming is required to clear the lock.

Can the 24-channel ADC operate simultaneously with the CAN controllers without performance degradation?

Yes - the ADC and CAN peripherals operate on independent clock domains and use separate DMA channels. Conversion triggers can be synchronized to reload timer overflow or external events without CPU intervention, and CAN message handling uses dedicated message object buffers and interrupt priority levels. Benchmarks confirm concurrent full-speed CAN traffic (1 Mbit/s) and continuous 100 kSPS ADC sampling with <2% CPU load in Run mode.
