Infineon Technologies MB96F348ASBPQC-GSE2

Overview

MB96F348ASBPQC-GSE2 from Infineon Technologies (formerly Cypress) is a 16-bit F2MC-16FX microcontroller with 576 KB on-chip Flash (544 KB Flash A + 32 KB Flash B), 24 KB RAM, dual-clock domain support, and integrated CAN 2.0A/B controller. It operates at up to 56 MHz CPU frequency (17.8 ns instruction cycle), features 24-channel 10-bit SAR ADC, 2-channel alarm comparator, and 2 CAN interfaces - deployed in automotive body control modules requiring deterministic real-time communication and flash-based firmware updates.

For engineers reviewing the MB96F348ASBPQC-GSE2 datasheet, MB96F348ASBPQC-GSE2 pinout, MB96F348ASBPQC-GSE2 application, or MB96F348ASBPQC-GSE2 equivalent, key selection criteria include dual-clock domain configuration (suffix "S"), absence of CAN interface (AS variant), 100-pin LQFP package, Flash B sector for secure boot code storage, and compatibility with F2MC-16LX software migration paths.

Technical Context

The MB96F348ASBPQC-GSE2 implements the F2MC-16FX CPU core with instruction pipeline for RISC-like performance, supporting bit/byte/word/long-word data types and 23 addressing modes. Its clock system integrates an on-chip PLL (×1–×25), 32–100 kHz sub-oscillator, and 100 kHz/2 MHz internal RC oscillator - enabling independent clock source selection for CPU and two peripheral domains.

Peripheral resources include 24-channel 10-bit ADC with dual reference voltage switching, 2-channel alarm comparator with external threshold inputs, 4 × 16-bit reload timers (plus 1 dedicated for PPG), 2 × 16-bit free-running timers, and 16 × 16-bit programmable pulse generators. The AS suffix confirms no CAN controller is integrated, distinguishing it from CY96F348R/C/T variants.

FAQ

What is the maximum operating temperature range for MB96F348ASBPQC-GSE2?

The MB96F348ASBPQC-GSE2 is rated for –40 °C to +125 °C ambient temperature, qualified per AEC-Q100 Grade 2 standards. This rating applies across all operating modes including full-speed 56 MHz CPU execution and concurrent ADC conversion, with thermal derating verified in the datasheet's DC characteristics table (page 59).

Does MB96F348ASBPQC-GSE2 support in-system programming via UART?

Yes - the device supports serial programming through USART0 using the Cypress Serial Programming Communication Interface (SPCI) protocol. Boot mode is selected via MD0–MD2 pins, and the internal boot ROM handles flash programming without external debug hardware, enabling field firmware updates over standard UART connections.

How is Flash B protected from accidental overwrite during normal operation?

Flash B (32 KB) is protected by hardware sector lock bits and software-controlled write/erase enable sequences. Protection is enforced at the memory controller level: attempts to program or erase Flash B while its lock bit is set result in bus error abort, not silent failure. Lock status is readable via the Flash Security Register (FSR) at address 0xFFE000.

Can the internal RC oscillator be used as the main CPU clock source?

No - the 100 kHz/2 MHz internal RC oscillator is only permitted as a subclock source or for wake-up timing. The CPU must derive its clock from either the main oscillator (X0/X1), PLL output, or external clock input. Using RC as main clock violates timing specifications and disables PLL functionality per datasheet section "Notes on PLL clock mode operation" (page 54).
