Infineon Technologies MB96F348TSAPMC-GSE2

Overview

MB96F348TSAPMC-GSE2 from Fujitsu is a 16-bit F2MC-16FX microcontroller with 544 kB Flash (main), 32 kB Flash (satellite), 24 kB RAM, 5 CAN interfaces (ISO 16845 certified), and operation up to 56 MHz (17.8 ns instruction cycle). It integrates a programmable PLL, on-chip voltage regulator, LCD controller (4 COM × 72 SEG), and 20-channel PPG - deployed in automotive body control modules requiring real-time CAN communication and low EMI.

For engineers reviewing the MB96F348TSAPMC-GSE2 datasheet, MB96F348TSAPMC-GSE2 pinout, MB96F348TSAPMC-GSE2 application, or MB96F348TSAPMC-GSE2 equivalent, key selection criteria include CAN 2.0A/B compliance, dual Flash bank architecture for safe firmware updates, peripheral clock domain independence, and automotive-grade I/O drive strength programming.

Technical Context

The MB96F348TSAPMC-GSE2 implements Fujitsu's F2MC-16FX core with instruction pipeline and 23 addressing modes, enabling RISC-like performance at 16-bit width. Its clock tree supports independent CPU and peripheral domains via main clock (up to 56 MHz), subclock (32 kHz), and internal RC (100 kHz/2 MHz) sources.

It features five fully independent CAN controllers compliant with ISO 11898-1 and ISO 16845, each with 32 message objects, programmable FIFO mode, and loop-back self-test. The integrated voltage regulator reduces internal V_CPU, lowering EMI and active power consumption across 13 operating modes including Stop and Sub-Stop.

FAQ

What is the maximum operating frequency and corresponding instruction cycle time?

The MB96F348TSAPMC-GSE2 achieves a maximum CPU clock of 56 MHz using its on-chip PLL, resulting in a minimum instruction cycle time of 17.8 ns. This timing is guaranteed under specified VDD and temperature conditions per the preliminary specification document FME-MB96300 rev 19.

Does this MCU support ISO 16845-certified CAN conformance testing?

Yes - all five CAN controllers in the MB96F348TSAPMC-GSE2 are ISO 16845 certified per the preliminary specification. Certification covers message filtering, error handling, bus arbitration, and loop-back self-test modes required for automotive ECU validation.

How is Flash memory organized, and does it support in-application programming?

Flash is split into 544 kB main bank and 32 kB satellite bank, enabling background read-while-write and safe firmware updates. Memory patch functionality allows runtime modification of code sections, and the device supports Flash programming via on-chip bootloader using CAN or SCI interfaces.

What packaging and thermal characteristics apply to the FPT-100P-M20 LQFP?

The FPT-100P-M20 is a 100-pin plastic LQFP with 0.5 mm pitch, JEDEC MO-220 compliant, and features an exposed thermal pad. Its θ_JA is 35°C/W (typical, 4-layer PCB), and maximum junction temperature is 125°C - validated for under-hood automotive use per AEC-Q100 stress test requirements.
