Infineon Technologies CY95F636HNPMC-G-UNERE2

Overview

CY95F636HNPMC-G-UNERE2 from Infineon Technologies (formerly Cypress) is an 8-bit Flash microcontroller based on the F2MC-8FX CPU core, featuring 36 KB on-chip Flash, 1024 bytes RAM, 28 I/O ports (25 CMOS + 3 N-ch open-drain), and integrated LIN-UART, I²C, UART/SIO, dual 8/16-bit composite timers, 8-channel 8/10-bit 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 CY95F636HNPMC-G-UNERE2 datasheet, CY95F636HNPMC-G-UNERE2 pinout, CY95F636HNPMC-G-UNERE2 application, or CY95F636HNPMC-G-UNERE2 equivalent, key selection criteria include Flash memory size (36 KB), standby mode flexibility (Stop/Sleep/Watch/Time-base timer with deep/normal options), LIN-UART master/slave capability, and dual-bank Flash for concurrent read/program operations.

Technical Context

This MCU implements a dedicated multi-pulse generator (MPG) with 16-bit PPG timer, 16-bit reload timer, and waveform sequencer for precise DC motor commutation timing. Its clock system supports four selectable main clock sources-including CR-PLL at 8/10/12/16 MHz ±2%-and independent subclock options (32.768 kHz or 100 kHz CR) enabling robust real-time clock and low-power wake-up functionality.

The interrupt architecture provides 10 external channels with edge-selectable detection (rising/falling/both), directly supporting sensor input conditioning and fault response in motor control loops. All timers-including two 8/16-bit composite timers, three 8/16-bit PPG channels, and time-base timer-share configurable clock sources (seven internal + external), allowing synchronized waveform generation across multiple peripherals without CPU intervention.

FAQ

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

The CY95F636HNPMC-G-UNERE2 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 with multiplication rate 4, the PLL output is 16 MHz ±2%, which serves as the machine clock. Minimum instruction execution time is 61.5 ns at this frequency, confirmed in the datasheet's CPU functions section.

Does this MCU support hardware LIN physical layer or require an external transceiver?

CY95F636HNPMC-G-UNERE2 integrates a LIN-UART peripheral that implements the LIN protocol stack (up to LIN 2.2) in hardware, including automatic baud rate detection and frame handling. However, it does not include the LIN physical layer driver; an external LIN transceiver (e.g., TLE7259-3GE) is required for bus-level signaling and ESD protection.

How many I/O pins support analog input and what ADC resolution options are available?

The device provides eight dedicated analog input pins (P00–P07 labeled AN00–AN07) connected to its single 8/10-bit successive approximation register (SAR) ADC. Resolution is software-selectable per conversion: 8-bit mode offers faster sampling (up to 1 MSPS), while 10-bit mode provides higher precision (±1 LSB INL) for sensor measurement applications such as temperature or current sensing.

Is on-chip debug supported, and what interface does it use?

Yes, on-chip debug is supported via a 1-wire serial interface using the P12/DBG pin. This allows asynchronous serial programming, breakpoint setting, and real-time register/memory inspection without requiring a dedicated debug header or SWD/JTAG pins. The interface is documented in Chapter 25 of the CY95630H Hardware Manual and requires only VCC, VSS, and the DBG line connected to a compatible programmer.
