Infineon Technologies MB96F348HSBPQC-GSE2

Overview

MB96F348HSBPQC-GSE2 from Infineon Technologies (formerly Cypress) is a 16-bit F2MC-16FX microcontroller with dual-clock architecture, 576 KB Flash (544 KB + 32 KB), 24 KB RAM, integrated dual CAN 2.0A/B controllers, 24-channel 10-bit SAR ADC, and 2-channel alarm comparator - deployed in automotive body control modules requiring deterministic real-time response and functional safety support.

For engineers reviewing the MB96F348HSBPQC-GSE2 datasheet, MB96F348HSBPQC-GSE2 pinout, MB96F348HSBPQC-GSE2 application, or MB96F348HSBPQC-GSE2 equivalent, key selection criteria include dual-CAN message object count (32 per channel), clock modulation for EMI reduction, on-chip voltage regulator for low-power operation, and flash security features enabling secure firmware updates in field-deployed ECUs.

Technical Context

The MB96F348HSBPQC-GSE2 implements the F2MC-16FX CPU core with instruction pipeline for RISC-like performance, supporting up to 56 MHz operation via internal PLL (x1–x25 multiplier) driven by a 4 MHz external resonator - achieving 17.8 ns minimum instruction cycle time. It integrates two independent CAN 2.0A/B controllers certified to ISO 16845, each with programmable FIFO mode and maskable interrupts.

A flexible clock tree enables independent frequency selection for CPU (up to 56 MHz) and peripheral domains (subsystem clock at 32–100 kHz, RC oscillator at 100 kHz/2 MHz), while on-chip clock modulation and voltage regulation jointly minimize emission peaks and internal power consumption across 13 operating modes including Stop, Sleep, and Timer-wakeup states.

FAQ

What clock sources does the MB96F348HSBPQC-GSE2 support?

The device supports three primary clock sources: an external 3–16 MHz crystal/resonator on X0/X1, a 32–100 kHz subsystem quartz oscillator, and an internal 100 kHz/2 MHz RC oscillator. The CPU and peripheral domains can independently select among these sources, enabling low-power subsystem operation while the CPU remains halted.

Does MB96F348HSBPQC-GSE2 support JTAG or SWD debugging?

No - this device uses Cypress's proprietary Serial Programming Communication Interface (SPCI) via dedicated pins (MD0–MD2, RSTX, and serial data lines) for programming and debug. It does not implement ARM-standard SWD or IEEE 1149.1 JTAG; debug access requires Cypress/Infineon-compatible programmers and software tools such as PSoC Programmer or ModusToolbox.

How is flash security implemented on MB96F348HSBPQC-GSE2?

Flash security is enforced through hardware lock bits that disable external read access to ROM/Flash contents during debug or serial programming. Once enabled, protected regions cannot be read via SPCI - preventing firmware reverse engineering. Security activation is irreversible and must be performed after final firmware validation.

Can the dual CAN controllers operate simultaneously at different bit rates?

Yes - each CAN channel (CAN0 and CAN1) has independent bit timing registers and clock dividers. They can be configured for distinct bit rates (e.g., 500 kbit/s on CAN0 for powertrain, 125 kbit/s on CAN1 for comfort systems) without cross-interference, supporting heterogeneous network topologies in multi-domain vehicle architectures.
