Product details
Overview
CY95F634HNPMC-G-UNE2 from Infineon Technologies (formerly Cypress) is an 8-bit Flash microcontroller based on the F2MC-8FX CPU core, featuring 20 KB flash memory, 1 KB RAM, and 28 I/O ports including 25 CMOS and 3 N-ch open-drain pins. It supports dual-bank Flash for concurrent read/program operations, 8/10-bit ADC across 8 channels, LIN-UART, I²C, UART/SIO, and multi-pulse generator for DC motor control - deployed in automotive body electronics and industrial sensor nodes.
For engineers reviewing the CY95F634HNPMC-G-UNE2 datasheet, CY95F634HNPMC-G-UNE2 pinout, CY95F634HNPMC-G-UNE2 application, or CY95F634HNPMC-G-UNE2 equivalent, key selection criteria include its 16.25 MHz max machine clock, deep standby modes (Stop/Sleep/Watch/Time-base), hardware/software watchdog timers, and integrated clock supervisor for main/sub-oscillation monitoring.
Technical Context
The device implements the F2MC-8FX core with 136 basic instructions, 1–3 byte instruction length, and 61.5 ns minimum execution time at 16.25 MHz. It integrates a clock supervisor counter that independently monitors both main (up to 16.25 MHz) and subclock (32.768 kHz or 100 kHz CR) oscillation stability.
Its peripheral set includes two 8/16-bit composite timers, three 8/16-bit PPG channels, one 16-bit PPG timer, one 16-bit reload timer, and a dedicated multi-pulse generator with waveform sequencer - all configurable for motor control timing, PWM generation, and event-triggered output toggling.

FAQ
What is the maximum operating frequency and supported clock sources?
The CY95F634HNPMC-G-UNE2 achieves a maximum machine clock frequency of 16.25 MHz. Supported clock sources include external crystal (up to 16.25 MHz), external clock input (up to 32.5 MHz), main CR oscillator (4 MHz ±2%), and main CR PLL (8/10/12/16 MHz ±2% depending on multiplication rate). The subclock supports 32.768 kHz crystal or 100 kHz CR source.
Does this MCU support in-system programming and debug?
Yes - it features 1-wire serial on-chip debug with asynchronous serial writing capability. Debug requires VCC, VSS, and a single serial wire connection to an evaluation tool. No JTAG or SWD interface is present; programming uses the dedicated DBG pin (P12) and EC0/EC1 signals per the hardware manual.
What are the key differences between CY95F634H and CY95F634K variants?
The "H" suffix (e.g., CY95F634HNPMC-G-UNE2) denotes absence of the low-voltage detection (LVD) reset circuit, while "K" variants integrate LVD with four selectable voltage thresholds. Both share identical Flash (20 KB), RAM (1 KB), I/O count (28), and peripheral sets - only LVD functionality and related register bits differ.
Is the multi-pulse generator (MPG) capable of standalone motor commutation?
Yes - the MPG includes a dedicated waveform sequencer with buffered 16-bit timer, compare-clear logic, and TRG1 input for synchronization. It can generate precise 3-phase commutation patterns for BLDC motors without CPU intervention, using only preloaded sequence tables and hardware-triggered state transitions.
