Product details
Overview
CY95F636KNWQN-G-UNE1 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, dual 8/10-bit ADC (8 channels), multi-pulse generator for DC motor control, and hardware/software watchdog timers. It operates up to 16.25 MHz machine clock with selectable clock sources including main CR PLL (up to 16 MHz ±2%) and supports four low-power standby modes.
For engineers reviewing the CY95F636KNWQN-G-UNE1 datasheet, CY95F636KNWQN-G-UNE1 pinout, CY95F636KNWQN-G-UNE1 application, or CY95F636KNWQN-G-UNE1 equivalent, key selection criteria include its QFN32 (WNP032) package, LIN master/slave capability, 29 I/O ports (25 CMOS + 4 N-ch open-drain), built-in low-voltage detection reset, and dual-bank Flash for concurrent read/program operations.
Technical Context
The CY95F636KNWQN-G-UNE1 implements the F2MC-8FX CPU core with 136 basic instructions, 1–3 byte instruction length, and 61.5 ns minimum execution time at 16.25 MHz. Its memory architecture includes dual-operation Flash banks enabling simultaneous program/erase in one bank while executing code from the other.
Peripheral integration centers on real-time control: two 8/16-bit composite timers, three 8/16-bit PPG channels, one 16-bit PPG timer, one 16-bit reload timer, a dedicated multi-pulse generator (MPG) with waveform sequencer for DC motor drive, and LIN-UART supporting both master and slave roles with full-duplex double buffering and programmable baud rates.

FAQ
What is the maximum operating frequency of the CY95F636KNWQN-G-UNE1?
The CY95F636KNWQN-G-UNE1 supports a maximum machine clock frequency of 16.25 MHz, achieved when using the external clock source at 32.5 MHz with 2× internal division. Its main CR PLL can generate 16 MHz ±2% output (PLL multiplication rate = 4), which serves as the system clock source for high-speed peripheral operation and minimal instruction cycle time (61.5 ns).
Does this MCU support LIN 2.2 protocol compliance?
Yes - the integrated LIN-UART peripheral supports LIN 2.2 physical layer signaling, including automatic sync-break detection, programmable baud rate generation (via dedicated reload timer), and full-duplex double-buffered transmission/reception. It operates as both LIN master and slave, with built-in wake-up functionality compliant with ISO 17987-4 timing requirements.
How many I/O pins support analog input and external interrupt simultaneously?
Eight I/O pins (P00–P07) each support simultaneous analog input (AN00–AN07), external interrupt (INT00–INT07), and general-purpose digital I/O. Each pin is individually configurable for interrupt edge sensitivity (rising/falling/both) and ADC channel selection, enabling direct sensor interfacing with hardware-triggered conversions and immediate wake-up from standby modes.
Is the Flash memory security feature enabled by default?
No - Flash security is disabled at factory shipment. It must be explicitly enabled via the Flash security command sequence during programming. Once activated, it prevents external readout of Flash contents and disables on-chip debug access. Security lock status is stored in dedicated Flash lock bits and persists through power cycles and resets.
