Infineon Technologies MB95F272KPF-G-SNE2

Overview

MB95F272KPF-G-SNE2 from Cypress Semiconductor is an 8-bit Flash microcontroller based on the F2MC-8FX CPU core, featuring 8 KB Flash memory, 240 bytes RAM, 5 I/O pins (3 CMOS + 2 N-ch open-drain), and dual-mode 8/10-bit A/D converter with 2 input channels. It supports multiple low-power standby modes and operates with main clock up to 16.25 MHz for embedded control in compact appliance subsystems.

For engineers reviewing the MB95F272KPF-G-SNE2 datasheet, MB95F272KPF-G-SNE2 pinout, MB95F272KPF-G-SNE2 application, or MB95F272KPF-G-SNE2 equivalent, key selection criteria include its 8-pin SOP package, absence of LIN-UART, single 8/16-bit composite timer channel, sub-CR clock support for watchdog, and Flash security features for firmware protection in cost-sensitive industrial controls.

Technical Context

This MCU implements the F2MC-8FX core with 136 basic instructions, 8-bit instruction width, and 1–3 byte variable-length encoding. It executes instructions in as little as 61.5 ns at 16.25 MHz machine clock and processes interrupts in 0.6 µs under same conditions.

It integrates a clock supervisor counter to monitor main oscillator stability, a hardware/software watchdog timer with selectable sub-CR clock source (50–200 kHz), and Flash memory supporting 100,000 program/erase cycles with 20-year data retention and security lock.

Key Specifications

FAQ

What clock sources does MB95F272KPF-G-SNE2 support?

It supports three main clock sources: main OSC (crystal or external up to 16.25 MHz), main CR (1/8/10 MHz ±3%), and external clock (up to 32.5 MHz). The sub-clock supports sub-OSC (32.768 kHz), external 32.768 kHz, or sub-CR (50–200 kHz), the latter used for watchdog and time-base timer.

Does MB95F272KPF-G-SNE2 include LIN or UART communication peripherals?

No. Unlike MB95F26xK/F28xK variants, the MB95F272KPF-G-SNE2 omits LIN-UART entirely - confirmed in the MB95270H Series section of Document 002-07516 Rev. *B, Page 6. Communication must be implemented via GPIO bit-banging or external transceivers.

What is the maximum operating voltage and temperature range?

The device operates from 2.7 V to 5.5 V over an industrial temperature range of −40 °C to +85 °C, as specified in the "Recommended Operating Conditions" table (Page 49) of Document 002-07516 Rev. *B. Absolute maximum supply voltage is 6.5 V.

How is Flash memory protected against unauthorized access?

It implements a Flash memory security function that locks program memory contents after programming - preventing read-out or reprogramming unless erased globally. This is enabled via dedicated security bits in the Flash configuration area, per Section "Flash memory security function" (Page 3).
