Infineon Technologies MB96F348ASBPMC-GSE2

Overview

MB96F348ASBPMC-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 no integrated CAN controller. It features an on-chip PLL enabling up to 56 MHz CPU operation from a 4 MHz resonator, 24-channel 10-bit SAR ADC, two alarm comparators, and 80 I/O pins in a 100-pin LQFP package. It targets automotive body control modules requiring secure firmware, low EMI, and fast wake-up from sleep modes.

For engineers reviewing the MB96F348ASBPMC-GSE2 datasheet, MB96F348ASBPMC-GSE2 pinout, MB96F348ASBPMC-GSE2 application, or MB96F348ASBPMC-GSE2 equivalent, key selection criteria include its dual-clock configuration (main + subclock), absence of CAN interface, 32 KB independent Flash B for data logging or patching, Flash security lock, and support for 13 low-power operating modes including Stop and Timer-wakeup modes.

Technical Context

The MB96F348ASBPMC-GSE2 implements the F2MC-16FX CPU core with instruction pipeline for RISC-like performance, backward compatibility with 16LX software, and 23 addressing modes. Its clock system supports independent selection of CPU and peripheral clock sources - main oscillator (3–16 MHz), sub-oscillator (32–100 kHz), or internal RC (100 kHz/2 MHz) - with configurable prescalers and clock modulation for EMI reduction.

It integrates a flexible peripheral set including four 16-bit reload timers, two 16-bit free-running timers, twelve input capture/output compare units, sixteen programmable pulse generators, two I²C interfaces (up to 400 kbps), seven full-duplex USARTs with LIN master/slave capability, and a 24-channel 10-bit ADC with dual reference voltage switching and external trigger support.

FAQ

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

The MB96F348ASBPMC-GSE2 achieves a maximum CPU frequency of 56 MHz using its on-chip PLL with multiplication factors from x1 to x25. When driven by a 4 MHz ceramic resonator, the PLL generates the 56 MHz clock internally, delivering a minimum instruction cycle time of 17.8 ns. This eliminates need for high-frequency external crystals while maintaining timing precision and reducing EMI.

Does this part support AEC-Q100 qualification and what grade applies?

Yes - the MB96F348ASBPMC-GSE2 is qualified to AEC-Q100 Grade 2 (–40 °C to +105 °C ambient), with full temperature range validation across electrical characteristics, reliability testing (HTOL, ESD, latch-up), and package robustness. The "GSE2" suffix denotes automotive-grade screening and traceability per Infineon's automotive quality system.

How does the Flash B partition differ from Flash A in usage and protection?

Flash B (32 KB) is architecturally independent from Flash A (544 KB): it supports separate erase/program commands, individual sector protection, and distinct security lock bits. This enables safe firmware patching - e.g., updating communication stack or calibration tables - without risking corruption of main application code stored in Flash A.

Can the sub-oscillator be used simultaneously with the main oscillator for real-time clock and CPU operation?

Yes - the dual-clock domain architecture allows the sub-oscillator (32.768 kHz) to drive the RTC and alarm comparators while the main oscillator (or PLL-derived clock) runs the CPU and high-speed peripherals. Clock source selection is fully independent per domain, enabling ultra-low-power timekeeping alongside active processing without clock gating delays.
