Infineon Technologies MB95F203KP-G-SH-SNE2

Overview

MB95F203KP-G-SH-SNE2 from Cypress Semiconductor is an 8-bit F2MC-8FX microcontroller with 8 KB Flash, 496 B RAM, and integrated LIN-UART, 8/10-bit A/D converter (6 channels), and dual 8/16-bit composite timers. It operates at up to 16.25 MHz machine clock (via external 32.5 MHz input), supports multiple low-power modes (stop/sleep/watch/timebase), and targets embedded control in industrial sensors and appliance motor interfaces.

For engineers reviewing the MB95F203KP-G-SH-SNE2 datasheet, MB95F203KP-G-SH-SNE2 pinout, MB95F203KP-G-SH-SNE2 application, or MB95F203KP-G-SH-SNE2 equivalent, key selection criteria include its SDIP-24 package, LIN-UART master/slave capability, 6-channel ADC with selectable 8/10-bit resolution, and dedicated reset (RSTX/PF2) with on-chip debug via 1-wire serial interface.

Technical Context

The MB95F203KP-G-SH-SNE2 implements the F2MC-8FX CPU core with 136 basic instructions, 1–3 byte encoding, and hardware support for multiplication/division and bit manipulation. Its clock system allows independent selection of main clock (up to 32.5 MHz external or 10 MHz internal CR) and subclock (32.768 kHz OSC or 50–200 kHz internal CR).

Peripheral integration includes a full-duplex LIN-UART with double buffer and clock-synchronized/asynchronous serial transfer, two 8/16-bit composite timers supporting PWM, input capture, and PWC functions, and six external interrupt inputs with edge-selectable wake-up from standby modes.

Key Specifications

Pinout & Package

FAQ

What clock sources does MB95F203KP-G-SH-SNE2 support for main and subclock domains?

The device supports three main clock sources: external crystal (up to 16.25 MHz), external clock input (up to 32.5 MHz), or internal CR oscillator (1/8/10 MHz ±3%). For subclock, it accepts 32.768 kHz crystal, external 32.768 kHz clock, or internal CR oscillator (50–200 kHz). These selections are configured via dedicated register bits and affect LIN baud rate accuracy and low-power mode timing.

Does MB95F203KP-G-SH-SNE2 require external Vpp for Flash programming?

Yes. Flash programming requires +10 V applied to the Vpp pin during write/erase operations. This voltage is not needed during normal operation or on-chip debug sessions using the 1-wire DBG interface, which relies solely on VCC and GND. The Vpp requirement is documented in the "Flash Memory Program/Erase Characteristics" section of the datasheet.

How many external interrupt channels are available, and what edge configurations do they support?

Six external interrupt channels (INT02–INT07) are available. Each supports rising edge, falling edge, or both edges via individual control bits in the interrupt configuration registers. These inputs double as analog inputs (AN02–AN05) and LIN-UART signals (SCK/SIN/SOT), enabling flexible wake-up triggers from sensor events, communication activity, or user interface signals.

Is the LIN-UART function compliant with LIN 2.2 specification?

The LIN-UART implements physical layer signaling and frame formatting per LIN 2.2, including break field detection, sync field handling, and checksum calculation. However, protocol stack implementation (e.g., schedule table management, node address assignment) resides in firmware. The hardware supports both master and slave roles and auto-baud detection via dedicated reload timer, meeting core timing requirements of LIN 2.2.
