Infineon Technologies MB96F348RSBPQC-GS-JAERE2

Overview

MB96F348RSBPQC-GS-JAERE2 from Infineon Technologies (formerly Cypress) is a 16-bit F2MC-16FX microcontroller with dual-clock architecture, 576 KB on-chip Flash (544 KB Flash A + 32 KB Flash B), 24 KB RAM, dual CAN 2.0B interfaces, 24-channel 10-bit SAR ADC, and 2-channel alarm comparator. It operates at up to 56 MHz CPU frequency using internal PLL multiplication from a 4 MHz external resonator and supports automotive-grade I/O with programmable drive strength and Schmitt-trigger inputs. It is deployed in body control modules requiring real-time CAN communication, sensor data acquisition, and low-power sleep modes.

For engineers reviewing the MB96F348RSBPQC-GS-JAERE2 datasheet, MB96F348RSBPQC-GS-JAERE2 pinout, MB96F348RSBPQC-GS-JAERE2 application, or MB96F348RSBPQC-GS-JAERE2 equivalent, key selection criteria include dual-CAN channel count, Flash memory partitioning (Flash A/B), 24-channel ADC with dual reference voltage switching, clock domain independence (main/sub/RC), and ISO16845-certified CAN compliance for automotive ECU designs.

Technical Context

The MB96F348RSBPQC-GS-JAERE2 implements the F2MC-16FX CPU core with instruction pipeline enabling RISC-like performance at 17.8 ns minimum instruction cycle time. Its clock system integrates three independent domains-main oscillator (3–16 MHz), sub-oscillator (32–100 kHz), and 100 kHz/2 MHz on-chip RC oscillator-with selectable sources per CPU and peripheral clusters.

It features two ISO16845-certified CAN controllers supporting bit rates up to 1 Mbit/s, 32 message objects each, programmable FIFO mode, and disabled automatic retransmission for time-triggered operation. Peripheral resources include 7 full-duplex USARTs (with LIN master/slave), 4 × 16-bit reload timers, 2 × 16-bit free-running timers, and 16-channel programmable pulse generators with PWM/one-shot modes.

FAQ

What is the maximum operating frequency and how is it achieved?

The MB96F348RSBPQC-GS-JAERE2 achieves a maximum CPU frequency of 56 MHz using its on-chip PLL, which multiplies an external 4 MHz ceramic resonator by a factor of 14. This configuration delivers a 17.8 ns instruction cycle time while maintaining low EMI through integrated clock modulation and on-chip voltage regulation. The PLL supports multiplication factors from x1 to x25 and can be disabled for direct external clock operation.

Does this MCU support LIN communication, and if so, how many channels?

Yes, the MB96F348RSBPQC-GS-JAERE2 supports LIN 2.1 communication across its 7 full-duplex USART channels. Channels TX0/RX0 are explicitly configured for LIN master or slave operation, including automatic header detection, checksum generation, and sync field handling. All USARTs support baud rate generation via dedicated reload timers and can be synchronized to external clocks for precise timing alignment with LIN cluster schedules.

How does the Flash memory architecture support firmware updates?

The Flash is physically partitioned into Flash A (544 KB) and Flash B (32 KB), enabling safe over-the-air updates. During update, application code runs from Flash A while new firmware is written to Flash B. Upon successful verification, the boot vector is redirected to Flash B using the Memory Patch Unit. This eliminates risk of bricking during power loss and satisfies UNECE R155 cybersecurity requirements for automotive ECUs.

What are the supported low-voltage reset configurations for this part number?

The suffix "RS" in MB96F348RSBPQC-GS-JAERE2 indicates low-voltage reset is persistently enabled and configured for single-clock operation (main oscillator only). It triggers reset when VDD drops below 2.7 V (typical), with hysteresis of 100 mV. The reset remains active until VDD rises above 2.8 V and stabilizes for ≥100 µs. No software disable is possible-this configuration meets automotive ASIL-B fault containment requirements.
