Infineon Technologies CY95F633KPMC-G-UNE2

Overview

CY95F633KPMC-G-UNE2 from Infineon Technologies (formerly Cypress) is an 8-bit Flash microcontroller based on the F2MC-8FX CPU core, featuring 12 KB on-chip Flash, 512 bytes RAM, and integrated peripherals including 8/10-bit ADC (8 channels), LIN-UART, I²C, UART/SIO, dual 8/16-bit composite timers, multi-pulse generator for DC motor control, and hardware/software watchdog timers. It operates at up to 16.25 MHz machine clock and supports four low-power standby modes.

For engineers reviewing the CY95F633KPMC-G-UNE2 datasheet, CY95F633KPMC-G-UNE2 pinout, CY95F633KPMC-G-UNE2 application, or CY95F633KPMC-G-UNE2 equivalent, key selection criteria include its LQFP32 package with 29 I/Os (25 CMOS + 4 N-ch open-drain), built-in low-voltage detection reset, clock supervisor counter, and dual-bank Flash enabling concurrent read/program operations.

Technical Context

The CY95F633KPMC-G-UNE2 implements the F2MC-8FX CPU core with 136 basic instructions, 8-bit instruction length (1–3 bytes), and 16-bit arithmetic support-including dedicated multiplication/division opcodes. Its memory architecture includes dual-operation Flash (12 KB) allowing simultaneous execution from one bank while programming/erasing the other.

Peripherals are tightly coupled to timing resources: the multi-pulse generator (MPG) integrates a 16-bit PPG timer, 16-bit reload timer, and waveform sequencer for precise DC motor phase control; the LIN-UART supports both master and slave roles with programmable baud rates via dedicated reload timer, and features full-duplex double buffering with NRZ format and LSB/MSB-first data transfer.

FAQ

What is the maximum operating frequency and corresponding machine clock specification?

The CY95F633KPMC-G-UNE2 supports an external clock input up to 32.5 MHz, yielding a maximum machine clock frequency of 16.25 MHz. When using the main CR PLL clock, selectable frequencies include 8 MHz ±2%, 10 MHz ±2%, 12 MHz ±2%, and 16 MHz ±2% depending on PLL multiplication rate (2× to 4×). This directly determines instruction execution speed and timer resolution.

Does this MCU support in-system programming via a single pin?

Yes-it features a 1-wire serial interface for on-chip debug and flash programming using only the DBG/EC0 pin (Pin 12), plus Vcc and Vss. This enables firmware updates and real-time debugging without JTAG headers, reducing test point count and simplifying production programming fixtures.

How does the low-voltage detection (LVD) function operate on this part?

The LVD circuit is present only on K-suffix variants (like CY95F633K) and offers four selectable detection/release voltage combinations (e.g., 2.7 V detect / 2.8 V release). It generates a reset when VDD drops below the selected threshold and releases reset only after VDD rises above the higher release voltage-preventing oscillatory resets during slow power ramp-up.

Can the multi-pulse generator (MPG) be used independently of the CPU core?

Yes-the MPG operates autonomously using its dedicated 16-bit PPG timer, 16-bit reload timer, and waveform sequencer. Once configured, it generates precise pulse trains (e.g., for BLDC commutation) without CPU intervention, freeing the F2MC-8FX core for higher-layer tasks like communication or safety monitoring.
