Infineon Technologies MB96F348RSBPQC-GSE2

Overview

MB96F348RSBPQC-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 + 32 KB), 24 KB RAM, 24-channel 10-bit SAR ADC, and 2-channel alarm comparator. It operates at up to 56 MHz CPU frequency (17.8 ns instruction cycle) using an internal PLL driven by a 4 MHz external resonator, and supports 13 low-power operating modes. It targets automotive body control modules requiring real-time CAN communication, sensor monitoring, and deterministic interrupt response.

For engineers reviewing the MB96F348RSBPQC-GSE2 datasheet, MB96F348RSBPQC-GSE2 pinout, MB96F348RSBPQC-GSE2 application, or MB96F348RSBPQC-GSE2 equivalent, key selection criteria include dual-CAN channel count, Flash memory partitioning (Flash A/B), subclock RTC calibration capability, programmable pulse generator (PPG) channel count (20), and dual-clock domain support (main + subsystem oscillator).

Technical Context

The MB96F348RSBPQC-GSE2 implements the F2MC-16FX CPU core with RISC-like pipelined execution, 23 addressing modes, barrel shift, and hardware signed multiply/divide (16×16/32÷16). Its clock tree enables independent frequency scaling for CPU (up to 56 MHz) and peripherals via main/sub oscillators or internal RC source.

It integrates two ISO16845-certified CAN controllers supporting bit rates up to 1 Mbit/s, 32 message objects each, FIFO concatenation, and Time-Triggered CAN mode with disabled automatic retransmission. The 24-channel ADC includes dual reference voltage switching (AVRH/AVRH2), while the alarm comparator monitors external analog voltages against programmable thresholds.

Key Specifications

Pinout & Package

FAQ

What is the maximum operating frequency of the MB96F348RSBPQC-GSE2 CPU?

The CPU achieves up to 56 MHz using its internal PLL clock multiplier, which accepts a 4 MHz external ceramic resonator as input. This yields a minimum instruction cycle time of 17.8 ns. Operation at this frequency requires proper decoupling, thermal management, and adherence to the recommended VCC range (4.5–5.5 V) per the datasheet's DC characteristics table.

Does MB96F348RSBPQC-GSE2 support Time-Triggered CAN (TTCAN)?

Yes-it supports TTCAN through programmable disable of automatic retransmission per CAN channel and precise synchronization via the subclock RTC. Each CAN controller provides 32 message objects with individual identifier masks and FIFO concatenation, enabling deterministic scheduling of transmission windows aligned to system time base.

How many programmable pulse generator (PPG) channels does this MCU have?

The MB96F348RSBPQC-GSE2 integrates 20 independent PPG channels. Each is a 16-bit down counter with separate cycle and duty registers, internal prescaler options (1/4–1/64), and support for PWM, one-shot, and trigger-synchronized operation-enabling precise motor phase control, LED dimming, and sensor excitation timing.

Is external memory expansion supported?

Yes-the MCU includes a multiplexed 16-bit external bus interface with up to 24-bit addressing, 6 chip select signals, wait-state control, and programmable timing. It supports connection to external SRAM, NOR Flash, or FPGA peripherals, and can operate as external bus master for co-processor configurations in complex control systems.
