Infineon Technologies MB95F572KPF-G-SNE2

Overview

MB95F572KPF-G-SNE2 from Cypress Semiconductor is an 8-bit Flash microcontroller in the MB95570H Series, featuring the F2MC-8FX CPU core, 8 KB Flash memory, 240 bytes RAM, and dual-operation Flash architecture enabling concurrent read/program-erase. It supports 8/10-bit A/D conversion across 2 channels, operates at up to 16.25 MHz machine clock (via external clock), and targets low-pin-count embedded control in space-constrained industrial sensors.

For engineers reviewing the MB95F572KPF-G-SNE2 datasheet, MB95F572KPF-G-SNE2 pinout, MB95F572KPF-G-SNE2 application, or MB95F572KPF-G-SNE2 equivalent, key selection criteria include its 5-pin I/O count (3 CMOS + 2 N-ch open-drain), absence of LIN-UART, support for four standby modes (Stop/Sleep/Watch/Time-base timer), and integrated low-voltage detection reset - critical for battery-powered sensor nodes requiring reliable brown-out recovery.

Technical Context

This MCU implements the F2MC-8FX core with 136 basic instructions, 1–3 byte instruction length, and 1/8/16-bit data handling. Its clock system includes selectable main sources (external clock up to 32.5 MHz, main CR at 4 MHz ±2%, scalable to 16 MHz via PLL) and subclock options (32.768 kHz crystal or 50–150 kHz sub-CR).

Peripheral integration centers on a single 8/16-bit composite timer with interval/PWM/input capture functions, a time-base timer (0.256 ms–8.3 s range), 2-channel 8/10-bit ADC (software-selectable resolution), hardware/software watchdog timers, and on-chip debug via 1-wire serial control with asynchronous serial writing capability.

FAQ

Does MB95F572KPF-G-SNE2 support LIN communication?

No. Unlike MB95F56xK/F58xK variants, the MB95F572KPF-G-SNE2 belongs to the MB95570H Series and explicitly omits LIN-UART functionality per Cypress Document 002-04629 Rev. *A, Page 4. It provides only basic UART-capable serial debug and no LIN protocol engine or dedicated LIN transceiver interface.

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

The MB95F572KPF-G-SNE2 achieves a maximum machine clock frequency of 16.25 MHz by accepting a 32.5 MHz external clock signal applied to the XT1 pin. This is confirmed in Section "Clock" of the datasheet (Page 1), where external clock input is specified up to 32.5 MHz, yielding half that value as the machine clock due to internal division.

Can the 8/10-bit ADC operate simultaneously on both channels?

No. The device has two ADC input channels but a single successive-approximation ADC core. Conversion is sequential: software initiates one channel at a time, with conversion time dependent on selected resolution (e.g., ~12 µs for 10-bit at 4 MHz clock). Simultaneous sampling is not supported.

Is the Flash memory security feature enabled by default?

No. Flash security must be explicitly programmed via the on-chip debug interface using Cypress-provided tools. Once enabled, it prevents unauthorized read-out of Flash contents and disables certain debug functions. The security bit is non-volatile and persists across power cycles until cleared via full chip erase.
