Infineon Technologies MB95F636KP-G-SH-SNE2

Overview

MB95F636KP-G-SH-SNE2 from Infineon Technologies (formerly Cypress) is an 8-bit Flash microcontroller based on the F2MC-8FX CPU core, featuring 36 KB on-chip Flash, 1024 bytes RAM, 29 I/O ports (25 CMOS + 4 N-ch open-drain), and integrated LIN-UART, I²C, UART/SIO, and 8/10-bit 8-channel ADC. It operates up to 16.25 MHz machine clock and supports four low-power standby modes - used in automotive body control modules and industrial sensor nodes.

For engineers reviewing the MB95F636KP-G-SH-SNE2 datasheet, MB95F636KP-G-SH-SNE2 pinout, MB95F636KP-G-SH-SNE2 application, or MB95F636KP-G-SH-SNE2 equivalent, key selection criteria include its LIN-UART master/slave capability, dual-bank Flash for concurrent read/program, on-chip debug via 1-wire serial interface, and built-in low-voltage detection reset with selectable threshold options.

Technical Context

The device implements the F2MC-8FX core with 136-instruction set, 1–3 byte variable-length encoding, and hardware support for multiplication/division and bit manipulation. Its clock system allows flexible sourcing: main oscillation (up to 16.25 MHz), external clock (up to 32.5 MHz), or CR-based PLL (8/10/12/16 MHz ±2%).

Peripheral integration includes a multi-pulse generator (MPG) for DC motor control with waveform sequencer, 16-bit reload timer, and 16-bit PPG timer; plus dual-mode 8/16-bit composite timers, full-duplex UART/SIO with double buffer, and I²C with wake-up function - all configurable via register-level control without external components.

FAQ

Does MB95F636KP-G-SH-SNE2 support in-system programming via the DBG pin?

Yes. The P12/DBG pin implements a 1-wire serial interface enabling full in-system programming and debugging without external tools. It supports asynchronous serial writing, breakpoint setting, and real-time register inspection - all using a single signal line and ground connection.

What is the maximum operating frequency of the main oscillator circuit?

The main oscillator supports crystals up to 16.25 MHz, yielding a maximum machine clock frequency of 16.25 MHz when using external clock input. With internal CR-based PLL, it achieves 16 MHz ±2% at PLL multiplication rate = 4 - verified under recommended operating conditions (V_CC = 4.5–5.5 V, T_A = –40 to +85 °C).

Can the 8/10-bit ADC operate during deep standby mode?

No. The ADC requires active CPU and peripheral clocks and is disabled in all standby modes including deep standby. However, the device can wake from deep standby via external interrupt or RTC alarm, then initiate ADC conversion within 10 µs of wake-up - enabling ultra-low average power in periodic sensing.

Is the LIN-UART compliant with ISO 17987-4 (LIN Physical Layer)?

Yes. The LIN-UART peripheral meets ISO 17987-4 requirements for bus driver characteristics, sync-break detection, and frame timing - confirmed by Infineon's characterization data. It supports LIN 2.1 protocol stack implementation without external transceiver when used with appropriate passive termination and slew-rate limiting.
