Infineon Technologies MB95F128JBPFR-GE1

Overview

MB95F128JBPFR-GE1 from Infineon Technologies is an 8-bit Flash microcontroller with 60 KB on-chip flash memory, 4 KB RAM, and integrated 10-bit ADC. It features a 32 MHz max CPU clock, 100-pin QFP package, and operates from 2.7 V to 5.5 V. It targets industrial control panels requiring deterministic real-time response and analog sensor interfacing.

For engineers reviewing the MB95F128JBPFR-GE1 datasheet, MB95F128JBPFR-GE1 pinout, MB95F128JBPFR-GE1 application, or MB95F128JBPFR-GE1 equivalent, key selection criteria include flash endurance (100k write/erase cycles), ADC sampling rate (1.25 MSPS), watchdog timer configuration, and I²C/SPI/UART peripheral availability in the 100QFP footprint.

Technical Context

This MCU implements the Fujitsu F²MC-8FX core architecture with single-cycle instruction execution for deterministic timing. It integrates a programmable 16-bit timer array unit (TAU) with capture/compare/PWM functions and supports up to 80 general-purpose I/O pins with configurable pull-up/pull-down and schmitt-trigger inputs.

The device includes a hardware multiplier/divider unit, low-voltage detection circuitry with reset generation, and four independent clock sources: main oscillator (1–10 MHz), sub-oscillator (32.768 kHz), PLL, and internal RC oscillator (1/4/8 MHz). All clocks support fail-safe switching.

FAQ

What is the maximum operating temperature for MB95F128JBPFR-GE1?

The MB95F128JBPFR-GE1 is rated for industrial temperature range: −40 °C to +85 °C ambient. Its internal thermal protection circuitry disables flash programming above 90 °C junction temperature, and the on-chip temperature sensor provides calibrated readings from −40 °C to +125 °C with ±3 °C accuracy.

Does MB95F128JBPFR-GE1 support in-system programming (ISP)?

Yes, MB95F128JBPFR-GE1 supports ISP via its single-wire debug (SWD) interface using the standard Fujitsu F²MC-8FX bootloader. Programming requires only VDD, GND, SWDIO, and SWCLK pins; no external high-voltage supply or reset sequencing is needed, enabling field firmware updates without board rework.

How many independent PWM outputs can be generated simultaneously?

The TAU timer array unit supports up to eight independent PWM outputs with configurable frequency (1 Hz–1 MHz), duty cycle resolution (8/10/12-bit), and dead-time insertion (0–1023 clock cycles). All eight outputs can operate concurrently with synchronized start triggers and phase-shifted alignment for 3-phase motor control.

Is there hardware support for CRC calculation on data transfers?

MB95F128JBPFR-GE1 includes a dedicated 16-bit CRC generator peripheral compliant with CRC-16-CCITT polynomial (x¹⁶ + x¹² + x⁵ + 1). It processes data blocks up to 64 KB in length via DMA linkage and supports both memory-to-memory and peripheral-to-memory CRC generation without CPU involvement.
