Infineon Technologies MB95F272KPH-G-SNE2

Overview

MB95F272KPH-G-SNE2 from Cypress Semiconductor is an 8-bit Flash microcontroller in the MB95270H series featuring the F2MC-8FX CPU core, 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 stop/sleep/watch/time-base timer low-power modes and operates with main clock up to 16.25 MHz (machine clock 8.125 MHz) for embedded control in space-constrained industrial sensors.

For engineers reviewing the MB95F272KPH-G-SNE2 datasheet, MB95F272KPH-G-SNE2 pinout, MB95F272KPH-G-SNE2 application, or MB95F272KPH-G-SNE2 equivalent, key selection criteria include its 8-pin DIP package, absence of LIN-UART, single 8/16-bit composite timer channel, 2-channel ADC, and dedicated reset input - critical for cost-sensitive, ultra-low-pin-count control nodes requiring flash security and on-chip debug via 1-wire serial interface.

Technical Context

The MB95F272KPH-G-SNE2 implements the F2MC-8FX 8-bit CPU core with 136 basic instructions, 1–3 byte instruction length, and support for 1/8/16-bit data operations including multiplication and division. Its clock system allows selection among main OSC (up to 16.25 MHz), external clock (up to 32.5 MHz), or main CR clock (1/8/10 MHz ±3%), with sub-clock options including 32.768 kHz sub-OSC or 50–200 kHz sub-CR.

It integrates a hardware/software watchdog timer with configurable reset cycle (e.g., 105 ms min at 10 MHz main clock), power-on reset, low-voltage detection reset (enabled), and clock supervisor counter for main oscillator monitoring. Standby modes include stop, sleep, watch, and time-base timer mode - all supporting wake-up via edge-triggered external interrupts on two channels.

FAQ

What package type and pin count does MB95F272KPH-G-SNE2 use?

MB95F272KPH-G-SNE2 uses an 8-pin plastic DIP package (DIP-8P-M03) with 2.54 mm lead pitch. It has five functional I/O terminals (P00–P04), plus VDD, VSS, RES, XT1, and XT2 - totaling eight pins. This package is through-hole mountable and compatible with standard 0.3-inch DIP sockets.

Does MB95F272KPH-G-SNE2 support LIN communication?

No. MB95F272KPH-G-SNE2 belongs to the MB95270H series, which explicitly excludes LIN-UART functionality per Cypress documentation (Document 002-07516 Rev. *A, Page 6). Unlike MB95260H/280H series variants, this device lacks LIN protocol support, full-duplex double-buffer UART, and clock-synchronized serial transfer capability.

What is the maximum operating frequency and corresponding machine clock speed?

The MB95F272KPH-G-SNE2 supports a maximum main oscillator clock of 16.25 MHz, yielding a maximum machine clock frequency of 8.125 MHz (since the F2MC-8FX core uses a 2-cycle-per-instruction architecture). External clock input can reach 32.5 MHz, but machine clock remains capped at 16.25 MHz under that configuration.

How many A/D converter channels does MB95F272KPH-G-SNE2 provide, and what resolutions are supported?

MB95F272KPH-G-SNE2 integrates a 2-channel 8/10-bit A/D converter. Each channel supports selectable resolution - either 8-bit (256 steps) or 10-bit (1024 steps) - with internal voltage reference. Conversion time is 13.3 µs per sample at 1 MHz ADC clock, and inputs are mapped to dedicated analog pins within the 5-pin I/O set.
