Infineon Technologies MB96F348RSBPMC-GSE2

Overview

MB96F348RSBPMC-GSE2 from Infineon Technologies (formerly Cypress) is a 16-bit F2MC-16FX microcontroller with dual CAN 2.0A/B interfaces, 576 KB on-chip Flash (544 KB Flash A + 32 KB Flash B), 24 KB RAM, and 100-pin LQFP package. It operates at up to 56 MHz CPU frequency (17.8 ns instruction cycle), features integrated voltage regulator, clock modulation for EMI reduction, and supports automotive-grade I/O with Schmitt-trigger inputs and programmable drive strength. Used in body control modules requiring real-time CAN communication and firmware update capability.

For engineers reviewing the MB96F348RSBPMC-GSE2 datasheet, MB96F348RSBPMC-GSE2 pinout, MB96F348RSBPMC-GSE2 application, or MB96F348RSBPMC-GSE2 equivalent, key selection criteria include dual-CAN channel count, Flash memory partitioning (Flash A/B), 24-bit RC/main/sub clock timers, LIN/SCI USART support, and dual alarm comparator for battery monitoring in automotive ECUs.

Technical Context

The MB96F348RSBPMC-GSE2 implements the F2MC-16FX CPU core with RISC-like pipelined execution, backward compatibility with 16LX software, and hardware acceleration for signed 16×16 multiply and 32÷16 divide. Its clock tree supports independent domain selection: CPU from PLL-multiplied 4 MHz resonator (up to 56 MHz), peripherals from main/sub/RC clocks, and RTC from 32–100 kHz quartz.

Peripheral integration includes two ISO16845-certified CAN controllers (32 message objects each, FIFO mode, loop-back test), ten full-duplex USARTs with LIN master/slave capability, four I²C channels (400 kbps), 24-channel 10-bit SAR ADC with dual reference voltage switching, and 16-bit programmable pulse generators with PWM/one-shot modes.

FAQ

What is the maximum operating frequency and corresponding instruction cycle time of the MB96F348RSBPMC-GSE2?

The MB96F348RSBPMC-GSE2 achieves a maximum CPU frequency of 56 MHz using its on-chip PLL with a 4 MHz external resonator. This yields a minimum instruction cycle time of 17.8 ns, verified in the official datasheet (002-04579 Rev. *C, page 2). The F2MC-16FX core maintains this performance with full backward compatibility to 16LX software.

Does MB96F348RSBPMC-GSE2 support LIN communication, and if so, how is it implemented?

Yes, MB96F348RSBPMC-GSE2 supports LIN communication through its full-duplex USARTs (SCI/LIN), with dedicated LIN functionality operating as either master or slave. Each USART channel can be configured for LIN 2.x frame handling, including auto-sync, checksum, and identifier filtering - confirmed in the peripheral description (page 2 of datasheet 002-04579 Rev. *C).

How many CAN controllers does MB96F348RSBPMC-GSE2 integrate, and what certification do they hold?

The MB96F348RSBPMC-GSE2 integrates two independent CAN 2.0A/B controllers, both certified to ISO16845 conformance test standard. Each supports bit rates up to 1 Mbit/s, 32 message objects, programmable FIFO mode, and loop-back self-test - detailed in the CAN section (page 2, datasheet 002-04579 Rev. *C).

What is the Flash memory architecture, and does it support secure firmware updates?

MB96F348RSBPMC-GSE2 features 576 KB Flash divided into 544 KB Flash A and 32 KB Flash B, enabling bank-swapping for safe firmware updates. It includes Flash Security to prevent unauthorized read-out and Memory Patch functionality to correct ROM content in-field - specified in Product Lineup (page 4) and Flash Memory section (page 94) of datasheet 002-04579 Rev. *C.
