Infineon Technologies CY95F564KPFT-G-UNE2

Overview

CY95F564KPFT-G-UNE2 from Cypress Semiconductor is an 8-bit Flash microcontroller in the MB95560H series featuring the F2MC-8FX CPU core, 20 KB Flash memory, 496 bytes RAM, LIN-UART interface, dual 8/16-bit composite timers, and 17 I/O ports (15 CMOS + 2 N-ch open-drain). It supports external clock up to 32.5 MHz (16.25 MHz machine clock), 8/10-bit A/D converter across 6 channels, and four low-power standby modes - used in automotive body control modules requiring LIN communication and deterministic real-time response.

For engineers reviewing the CY95F564KPFT-G-UNE2 datasheet, CY95F564KPFT-G-UNE2 pinout, CY95F564KPFT-G-UNE2 application, or CY95F564KPFT-G-UNE2 equivalent, key selection criteria include LIN master/slave capability, dual timer configuration flexibility, Flash security function, sub-CR clock support for watchdog timing, and LCC-32 package compatibility with board-level EMI constraints.

Technical Context

The CY95F564KPFT-G-UNE2 implements the F2MC-8FX core with 136 basic instructions, 1–3 byte instruction length, and 61.5 ns minimum execution time at 16.25 MHz machine clock. It integrates a clock supervisor counter that actively monitors main oscillation stability and triggers reset on failure.

Its LIN-UART supports full-duplex double-buffered operation with configurable baud rates via dedicated reload timer, enabling both clock-synchronous and asynchronous serial transfer - essential for ISO 17987-compliant automotive subnetworks where deterministic latency and error recovery are required.

FAQ

What is the maximum machine clock frequency supported by CY95F564KPFT-G-UNE2?

The device supports a maximum machine clock frequency of 16.25 MHz, achieved when using an external clock input up to 32.5 MHz with 2× division. This timing enables 61.5 ns minimum instruction execution and meets LIN 2.2A baud rate accuracy requirements across temperature and voltage ranges.

Does CY95F564KPFT-G-UNE2 support LIN slave functionality?

Yes, the integrated LIN-UART supports both master and slave roles per ISO 17987-4. It includes automatic sync field detection, checksum calculation, and frame buffering - allowing seamless integration into existing LIN clusters without external protocol translation.

How many analog input channels does CY95F564KPFT-G-UNE2 provide?

The device provides six analog input channels (AN0–AN5), each configurable for either 8-bit or 10-bit resolution. These share physical pins with general-purpose I/O, enabling flexible PCB layout while supporting sensor interfaces such as potentiometers, thermistors, and voltage monitoring.

Is the Flash memory in CY95F564KPFT-G-UNE2 protected against unauthorized access?

Yes, it includes a hardware-enforced Flash memory security function that blocks read-out of program memory contents via debug interface or serial programming. Once enabled, security cannot be disabled without full chip erase - satisfying OEM anti-cloning and IP protection mandates.
