Infineon Technologies MB95F636KWQN-G-SNE1

Overview

MB95F636KWQN-G-SNE1 from Infineon Technologies (formerly Cypress) is an 8-bit Flash microcontroller based on the F2MC-8FX CPU core, featuring 36 KB on-chip Flash memory, 1024 bytes RAM, and integrated LIN-UART, I²C, UART/SIO, and 8/10-bit ADC across 8 channels. It supports up to 16.25 MHz machine clock via external clock input and operates in four low-power standby modes - Stop, Sleep, Watch, and Time-base Timer - for battery-powered motor control and automotive body electronics.

For engineers reviewing the MB95F636KWQN-G-SNE1 datasheet, MB95F636KWQN-G-SNE1 pinout, MB95F636KWQN-G-SNE1 application, or MB95F636KWQN-G-SNE1 equivalent, key selection criteria include its dual-bank Flash architecture enabling concurrent read/program operations, built-in clock supervisor counter for main/sub-clock monitoring, and dedicated multi-pulse generator (MPG) with waveform sequencer for DC motor timing control.

Technical Context

The MB95F636KWQN-G-SNE1 implements the F2MC-8FX CPU core with 136 basic instructions, 8-bit instruction length (1–3 bytes), and 16-bit arithmetic support including multiplication/division. Its clock system allows independent selection of main clock (up to 32.5 MHz external, 16.25 MHz max machine clock) and subclock (32.768 kHz or 100 kHz ±50%) sources, with PLL options yielding 8/10/12/16 MHz outputs from a 4 MHz CR oscillator.

Peripheral integration includes a 1-channel multi-pulse generator (MPG) with 16-bit PPG timer, 16-bit reload timer, event counter, and waveform sequencer - all optimized for closed-loop DC motor drive. The device also embeds hardware/software watchdog timers, power-on reset, and low-voltage detection reset (enabled on K-series variants), with debug access via 1-wire serial interface.

FAQ

Does MB95F636KWQN-G-SNE1 support in-system programming via LIN?

Yes - the device supports LIN-UART-based firmware updates using its full-duplex double-buffered LIN interface. The embedded algorithm enables automatic programming with erase-suspend/resume commands, and the Flash security function can be configured to protect against unauthorized writes during field updates.

What is the maximum ADC sampling rate at 10-bit resolution?

At 10-bit resolution, the ADC achieves a maximum conversion time of 16 μs per channel (62.5 kSPS aggregate rate across 8 channels), with programmable sample-and-hold timing and support for burst mode triggered by timer events or external signals.

Can the multi-pulse generator operate independently of the CPU core?

Yes - the MPG runs autonomously using its internal 16-bit PPG timer and waveform sequencer. Once configured, it generates precise pulse trains without CPU intervention, freeing the F2MC-8FX core for higher-layer control tasks like PID computation or communication handling.

Is the QFN package (WNP032) RoHS-compliant and lead-free?

Yes - MB95F636KWQN-G-SNE1 uses a lead-free, halogen-free QFN package compliant with RoHS Directive 2011/65/EU and JEDEC J-STD-020 moisture sensitivity level 3 (MSL3), requiring bake conditioning before reflow if exposed to ambient >30°C/60% RH for >168 hours.
