Infineon Technologies CY95F636KNPMC-G-UNE2

Overview

CY95F636KNPMC-G-UNE2 from Infineon Technologies (formerly Cypress) 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, 8/10-bit 8-channel ADC, and multi-pulse generator for DC motor control. It operates at up to 16.25 MHz machine clock using external or CR-PLL sources and targets embedded control in automotive body electronics and industrial actuators.

For engineers reviewing the CY95F636KNPMC-G-UNE2 datasheet, CY95F636KNPMC-G-UNE2 pinout, CY95F636KNPMC-G-UNE2 application, or CY95F636KNPMC-G-UNE2 equivalent, key selection criteria include Flash security, dual-bank simultaneous read/program capability, low-voltage detection reset (enabled on K-series), deep standby power modes, and LIN master/slave support with dedicated reload timer for baud rate flexibility.

Technical Context

This MCU 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. It integrates a clock supervisor counter that independently monitors main and subclock oscillation stability - critical for fail-safe timing in automotive subsystems.

The peripheral set includes a multi-pulse generator (MPG) with waveform sequencer, 16-bit PPG timer, and 16-bit reload timer supporting toggle/one-shot output - all synchronized for precise DC motor phase control. LIN-UART supports both master and slave roles with full-duplex double buffering and NRZ transfer format.

FAQ

What is the maximum operating frequency of the CY95F636KNPMC-G-UNE2?

The CY95F636KNPMC-G-UNE2 supports a maximum machine clock frequency of 16.25 MHz, achieved when using an external clock source up to 32.5 MHz with 2× division. At this speed, the minimum instruction execution time is 61.5 ns, and interrupt processing time is 0.6 µs - verified in the datasheet's AC characteristics table under recommended operating conditions.

Does CY95F636KNPMC-G-UNE2 support in-system programming via its debug interface?

Yes - it features a 1-wire on-chip debug interface (pin P12/DBG/EC0) supporting asynchronous serial writing and real-time register inspection. Programming requires only VCC, VSS, and the DBG line connected to a compatible evaluation tool, with no external debugger hardware needed for basic flash updates.

Is the low-voltage detection (LVD) function available on this specific part number?

Yes - the "K" suffix in CY95F636KNPMC-G-UNE2 explicitly denotes inclusion of the low-voltage detection reset circuit. Four LVD threshold combinations are configurable in software (e.g., 4.0 V detect / 4.1 V release), and the function remains active in all standby modes except Stop mode.

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

Yes - the MPG block includes its own 16-bit reload timer, 16-bit PPG timer, event counter, and waveform sequencer with buffer and compare-clear logic. Once configured, it generates precise pulse trains autonomously, freeing the CPU for higher-level tasks such as LIN message handling or PID computation.
