Infineon Technologies CY95F632KPMC-G-UNE2

Overview

CY95F632KPMC-G-UNE2 from Infineon Technologies (formerly Cypress) is an 8-bit Flash microcontroller based on the F2MC-8FX CPU core, featuring 8 KB Flash, 256 bytes RAM, 29 I/O ports (25 CMOS + 4 N-ch open-drain), 8/10-bit 8-channel ADC, LIN-UART, I²C, and multi-pulse generator for DC motor control. It operates up to 16.25 MHz machine clock with selectable clock sources including CR PLL (up to 16 MHz ±2%) and supports four low-power standby modes.

For engineers reviewing the CY95F632KPMC-G-UNE2 datasheet, CY95F632KPMC-G-UNE2 pinout, CY95F632KPMC-G-UNE2 application, or CY95F632KPMC-G-UNE2 equivalent, key selection criteria include its integrated LIN-UART with master/slave capability, on-chip low-voltage detection reset (LVD), dual-bank Flash enabling concurrent read/program, and hardware/software watchdog timers - all in a 32-pin LQFP package.

Technical Context

The CY95F632KPMC-G-UNE2 implements the F2MC-8FX CPU core with 136 basic instructions, 8-bit data width, and 1–3 byte instruction length, delivering minimum execution time of 61.5 ns at 16.25 MHz. Its memory architecture includes dual-operation Flash (upper/lower bank), enabling real-time firmware updates without halting execution.

Peripherals are tightly coupled to power management: 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 configurable baud rates via dedicated reload timer and operates in both master and slave roles with full-duplex double-buffered transfer.

FAQ

What is the maximum operating frequency and supported clock sources for CY95F632KPMC-G-UNE2?

The CY95F632KPMC-G-UNE2 supports a maximum machine clock frequency of 16.25 MHz, achievable only with the external clock source (up to 32.5 MHz input). Other valid sources include main oscillation clock (≤16.25 MHz), main CR clock (4 MHz ±2%), and main CR PLL clock (8/10/12/16 MHz ±2% depending on PLL multiplier). The subclock (32.768 kHz or 100 kHz) serves low-power timing functions.

Does CY95F632KPMC-G-UNE2 support in-system programming and debug via a single pin?

Yes - it features 1-wire serial on-chip debug using the DBG pin (P12), enabling flash programming, breakpoint insertion, and real-time register inspection without requiring JTAG or SWD interfaces. This single-pin debug capability simplifies board layout and reduces test point count during development and field servicing.

How does the multi-pulse generator (MPG) function in motor control applications?

The MPG integrates a dedicated 16-bit PPG timer, 16-bit reload timer, and waveform sequencer to generate precise, synchronized pulse trains for brushed DC motor commutation. It operates autonomously without CPU intervention, supporting toggle output, one-shot output, and event counting - enabling smooth acceleration/deceleration and stall detection while freeing the CPU for higher-level tasks.

Is low-voltage detection (LVD) available on all variants of the CY95630H series?

No - LVD is exclusive to the "K" suffix variants (CY95F632K, CY95F633K, etc.), including CY95F632KPMC-G-UNE2. The "H" variants lack this feature. The LVD circuit offers four selectable detection/release voltage combinations (e.g., 3.8 V/4.0 V or 4.2 V/4.4 V), allowing robust brown-out handling across varying 12V supply conditions in automotive environments.
