Infineon Technologies MB95F434KPMC-G-SNE2

Overview

MB95F434KPMC-G-SNE2 from Fujitsu Semiconductor is an 8-bit F2MC-8FX microcontroller with 20 KB Flash, 496 bytes RAM, 29 I/O ports (27 CMOS + 2 N-ch open-drain), 8/10-bit 17-channel ADC, integrated OPAMP with software-selectable gain, and low-voltage detection reset. It operates up to 16.25 MHz machine clock using external or CR clocks and targets embedded control in induction heaters, industrial sensors, and power-supply monitors.

For engineers reviewing the MB95F434KPMC-G-SNE2 datasheet, MB95F434KPMC-G-SNE2 pinout, MB95F434KPMC-G-SNE2 application, or MB95F434KPMC-G-SNE2 equivalent, key selection criteria include its dual-bank Flash security, on-chip debug via 1-wire serial, hardware/software watchdog timers, and integrated voltage comparator/OPAMP for current-sensing feedback loops.

Technical Context

The MB95F434KPMC-G-SNE2 implements the F2MC-8FX CPU core with 136 basic instructions, 1–3 byte instruction length, and 61.5 ns minimum execution time at 16.25 MHz. Its peripheral set includes a 16-bit PPG with PWM/single-shot modes, two 16-bit output compare channels, and a time-base timer supporting intervals from 0.256 ms to 8.3 s.

It integrates four independent voltage comparators, one operational amplifier configurable for ground-current sensing in induction heating applications, and supports simultaneous Flash read/program-erase across upper/lower banks. The device includes dedicated low-voltage detection reset (LVD) and clock supervisor counter - features exclusive to the 'K' variant series.

FAQ

What is the maximum operating frequency and supported clock sources for MB95F434KPMC-G-SNE2?

The device supports up to 16.25 MHz machine clock frequency using external clock (≤32.5 MHz input), main crystal oscillator (≤16.25 MHz), or main CR oscillator (1/8/10/12.5 MHz ±2%). Subclock options include 32.768 kHz crystal or 50–200 kHz sub-CR oscillator for low-power timing.

Does MB95F434KPMC-G-SNE2 support in-system programming and debug without external tools?

Yes - it features 1-wire serial on-chip debug with asynchronous serial writing capability. Only VCC, VSS, and a single debug pin (P12/DBG) are required for flash programming and real-time debugging, eliminating need for dedicated JTAG emulators.

How does the dual-bank Flash architecture benefit firmware updates?

Dual-bank Flash allows one bank to execute code while the other is being erased or programmed. This enables seamless firmware updates in the field without interrupting real-time control tasks - critical for industrial equipment requiring zero-downtime maintenance.

Can the integrated OPAMP be used independently of the ADC or comparator peripherals?

Yes - the OPAMP can operate in standalone mode with software-selectable closed-loop gain (7 options). Its output (P62/OPAMP_O) feeds directly into ADC channel 16, but the amplifier itself functions as a general-purpose rail-to-rail opamp for external signal conditioning when not tied to ADC inputs.
