Product details
Overview
MB96F346RWBPMC-GSE2 from Infineon Technologies (formerly Cypress) is a 16-bit F2MC-16FX microcontroller with dual-clock domain support (main + sub-oscillator), 416 KB Flash (Flash A: 352 KB + Data Flash: 64 KB), 16 KB RAM, two CAN 2.0B interfaces, 24-channel 10-bit SAR ADC, and integrated voltage regulator. It operates at up to 56 MHz CPU frequency via on-chip PLL driven by a 4 MHz external resonator, achieving 17.8 ns instruction cycle time for real-time automotive body control applications.
For engineers reviewing the MB96F346RWBPMC-GSE2 datasheet, MB96F346RWBPMC-GSE2 pinout, MB96F346RWBPMC-GSE2 application, or MB96F346RWBPMC-GSE2 equivalent, key selection criteria include dual-clock RTC support, ISO16845-certified CAN timing compliance, flash security features, and 16-channel PPG for motor control waveform generation.
Technical Context
The MB96F346RWBPMC-GSE2 implements the F2MC-16FX CPU core with RISC-like pipelined execution, 23 addressing modes, barrel shift, and signed multiply/divide instructions. Its clock tree supports independent CPU and peripheral domain frequencies-CPU sourced from PLL-multiplied main clock (up to 56 MHz), peripherals selectable from main oscillator, 32–100 kHz sub-oscillator, or 100 kHz/2 MHz internal RC oscillator.
It integrates two ISO16845-certified CAN controllers (bit rates up to 1 Mbit/s, 32 message objects each), seven full-duplex USARTs with LIN master/slave capability, four I²C channels (400 kbps), and a 24-channel ADC with dual reference voltage switching (AVRH/AVRL or AVRH2). The device includes 16 DMA channels, 12 input capture units, and 12 output compare units for precise timing control.
