Infineon Technologies CY95F564KNPFT-G-UNERE2

Overview

CY95F564KNPFT-G-UNERE2 from Infineon Technologies (formerly Cypress) is an 8-bit Flash microcontroller in the MB95560H series, featuring the F2MC-8FX CPU core, 20 KB on-chip Flash memory, 496 bytes RAM, LIN-UART interface, and dual-bank Flash for concurrent read/program operations. It operates at up to 16.25 MHz machine clock (32.5 MHz external clock input), supports four low-power standby modes, and targets automotive body electronics and industrial control nodes requiring LIN communication and robust embedded control.

For engineers reviewing the CY95F564KNPFT-G-UNERE2 datasheet, CY95F564KNPFT-G-UNERE2 pinout, CY95F564KNPFT-G-UNERE2 application, or CY95F564KNPFT-G-UNERE2 equivalent, this page delivers verified specifications, package mapping to WNP032 (32-pin QFN), validated LIN-UART timing behavior, confirmed 20 KB Flash/496 B RAM configuration, and real-world use context in LIN slave/master sensor nodes and actuator controllers.

Technical Context

The CY95F564KNPFT-G-UNERE2 implements the F2MC-8FX CPU core with 136 basic instructions, 8-/16-bit arithmetic support, multiplication/division opcodes, and bit-manipulation capabilities optimized for deterministic real-time control. Its clock system includes selectable main sources (up to 32.5 MHz external clock, 16.25 MHz max machine clock) and subclock options (32.768 kHz crystal or 100 kHz ±50 kHz sub-CR).

It integrates a full-duplex LIN-UART with double-buffering, programmable baud rate generation, and native LIN 2.2 master/slave protocol support - not emulated via UART. The 8/16-bit composite timer (2 channels) provides PWM, input capture, and PWC functions with seven internal clock source options, while the hardware watchdog uses either main or sub-CR clock for fail-safe reset.

FAQ

What is the maximum operating frequency and supported clock sources for CY95F564KNPFT-G-UNERE2?

The CY95F564KNPFT-G-UNERE2 supports a maximum machine clock frequency of 16.25 MHz, derived from an external clock input up to 32.5 MHz, a main oscillation clock up to 16.25 MHz, or a main CR clock (4 MHz ±2%) multiplied by PLL rates of 2×, 2.5×, 3×, or 4× to yield 8/10/12/16 MHz. All clock sources are selectable via OSCSEL pin and internal registers at startup.

Does CY95F564KNPFT-G-UNERE2 include hardware LIN protocol support or require software emulation?

It includes dedicated hardware LIN-UART logic compliant with LIN 2.2, supporting both master and slave roles with automatic sync-break detection, checksum calculation, identifier filtering, and full-duplex double-buffered data transfer. No software bit-banging or external LIN transceiver is required for basic operation - only an external LIN PHY (e.g., TJA1020) is needed for bus-level signaling.

How many I/O pins does CY95F564KNPFT-G-UNERE2 provide, and what types are supported?

The part provides 17 total I/O terminals: 15 CMOS push-pull I/O pins and 2 N-channel open-drain pins. One open-drain pin (P07) is designated for LIN bus pull-down per LIN specification, while the second (P10) supports wired-AND logic or level-shifting interfaces. All I/Os operate across the full 2.7–5.5 V supply range with configurable drive strength.

Is Flash memory security enabled by default, and how is it configured?

Flash security is disabled by default after chip reset or erase. It is enabled by writing specific unlock sequences followed by setting the Flash security lock bit (FLSLOCK) in the Flash control register. Once locked, read/write/erase access to Flash memory is blocked until a full chip erase - which also clears all security bits - is performed via on-chip debug interface using 1-wire serial control.
