Infineon Technologies CY95F564KNPFT-G111UNERE2

Overview

CY95F564KNPFT-G111UNERE2 from Infineon Technologies (formerly Cypress) is an 8-bit Flash microcontroller in the MB95560H series, featuring the F2MC-8FX CPU core, 20 KB Flash, 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 input), supports four low-power standby modes, and targets automotive body electronics and industrial control nodes.

For engineers reviewing the CY95F564KNPFT-G111UNERE2 datasheet, CY95F564KNPFT-G111UNERE2 pinout, CY95F564KNPFT-G111UNERE2 application, or CY95F564KNPFT-G111UNERE2 equivalent, key selection criteria include LIN bus master/slave capability, 17-pin I/O count (15 CMOS + 2 N-ch open-drain), 8/10-bit ADC with 6 channels, 2-channel 8/16-bit composite timer, and integrated clock supervisor counter.

Technical Context

The device implements the F2MC-8FX CPU core with 136 basic instructions, 8-bit instruction width, and 1–3 byte variable-length encoding, enabling 61.5 ns minimum instruction execution at 16.25 MHz. Its LIN-UART supports full-duplex double-buffered communication with both synchronous and asynchronous serial transfer modes.

Flash memory uses dual-operation architecture: program/erase in one bank while reading from the other. The on-chip clock supervisor counter monitors main oscillation stability, and the hardware watchdog timer accepts sub-CR clock (50–150 kHz) as a fail-safe timing source independent of the main clock domain.

FAQ

Does CY95F564KNPFT-G111UNERE2 support LIN 2.2 physical layer compliance?

Yes. The integrated LIN-UART supports LIN 2.2-compliant signaling with programmable slew rate control, recessive/dominant voltage threshold detection, and automatic sync-break detection. It meets ISO 17987-4 electrical specifications when paired with a standard LIN transceiver such as TLE7259-3GE.

What is the maximum allowable clock frequency for external CLKIN operation?

The external clock input (CLKIN) supports frequencies up to 32.5 MHz. At this input rate, the internal machine clock runs at 16.25 MHz-the maximum specified for reliable operation of all peripherals including ADC conversion and LIN bit timing.

Can the dual-bank Flash be used to implement a bootloader with atomic firmware updates?

Yes. The dual-bank architecture allows one bank to execute active firmware while the other receives new code via LIN or UART. Upon successful CRC verification, the boot vector is redirected-ensuring zero-downtime updates without risk of bricking the device during power loss.

Is the sub-CR clock (100 kHz) factory-trimmed for accuracy?

No. The sub-CR clock has a typical frequency of 100 kHz with a guaranteed range of 50–150 kHz across temperature and voltage. It is not trimmed but is sufficiently stable for watchdog timeout and wake-up timing where absolute precision is not required.
