Infineon Technologies CY95F636KPMC-G-UNE2

Overview

CY95F636KPMC-G-UNE2 from Cypress Semiconductor is an 8-bit F2MC-8FX microcontroller with 36 KB Flash, 1024-byte RAM, 29 I/O ports (25 CMOS + 4 N-ch open-drain), and integrated LIN-UART, I²C, UART/SIO, dual 8/16-bit composite timers, 8/10-bit 8-channel ADC, and multi-pulse generator for DC motor control. It operates up to 16.25 MHz machine clock using external or CR-PLL sources and targets embedded motor control and industrial sensor nodes.

For engineers reviewing the CY95F636KPMC-G-UNE2 datasheet, CY95F636KPMC-G-UNE2 pinout, CY95F636KPMC-G-UNE2 application, or CY95F636KPMC-G-UNE2 equivalent, key selection criteria include its 36 KB dual-bank Flash with security, low-voltage detection reset (4 selectable thresholds), 4 standby modes with deep sleep, and hardware/software watchdog timers - all in a 32-pin LQFP package.

Technical Context

The CY95F636KPMC-G-UNE2 implements the F2MC-8FX CPU core with 136 instructions, 1–3 byte encoding, and 61.5 ns minimum instruction cycle at 16.25 MHz. Its memory architecture supports simultaneous read from one Flash bank while programming/erasing the other, enabling seamless firmware updates without halting execution.

Peripheral integration centers on deterministic real-time control: the multi-pulse generator (MPG) combines a 16-bit PPG timer, 16-bit reload timer, and waveform sequencer with buffer and compare-clear for precise DC motor commutation; LIN-UART supports both master and slave roles with full-duplex double buffering and programmable baud rates via dedicated reload timer.

FAQ

What is the maximum operating frequency of the CY95F636KPMC-G-UNE2?

The CY95F636KPMC-G-UNE2 supports a maximum machine clock frequency of 16.25 MHz, achievable using the external clock input (up to 32.5 MHz) or the main CR PLL clock configured at ×4 multiplication (16 MHz ±2%). This yields a 61.5 ns minimum instruction execution time and 0.6 µs interrupt response latency at full speed.

Does this microcontroller support in-circuit debugging?

Yes - the CY95F636KPMC-G-UNE2 includes a 1-wire serial on-chip debug interface supporting asynchronous serial writing and real-time register inspection. Debug requires only VCC, VSS, and a single serial wire (Pin P12/DBG/EC0), eliminating JTAG overhead and reducing PCB footprint.

How many analog-to-digital converter channels does it have, and what resolutions are supported?

The device integrates an 8-channel SAR ADC supporting both 8-bit and 10-bit resolution per channel. Inputs map directly to P00–P07 pins (AN00–AN07), with selectable reference voltage (VCC or internal bandgap) and programmable sampling time - enabling simultaneous temperature, voltage, and current sensing in motor control loops.

Is the low-voltage detection feature configurable?

Yes - the built-in low-voltage detection reset circuit offers four preset combinations of detection and release voltages (e.g., 2.7 V detect / 2.8 V release, 3.3 V detect / 3.4 V release). Configuration is performed via dedicated flash option bits during programming, allowing tailoring to specific power rail tolerances without external components.
