Infineon Technologies CY95F564KNPF-G-UNE2

Overview

CY95F564KNPF-G-UNE2 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-operation Flash architecture. It supports up to 16.25 MHz machine clock frequency, 8/10-bit A/D conversion across 6 channels, and operates in four low-power standby modes - used in automotive body control modules requiring robust LIN communication and deterministic real-time response.

For engineers reviewing the CY95F564KNPF-G-UNE2 datasheet, CY95F564KNPF-G-UNE2 pinout, CY95F564KNPF-G-UNE2 application, or CY95F564KNPF-G-UNE2 equivalent, key selection criteria include LIN master/slave capability, dual-bank Flash for concurrent read/program, sub-CR clock support for watchdog timing, and N-ch open-drain I/O for direct LED/load driving in space-constrained automotive subsystems.

Technical Context

The device implements the F2MC-8FX CPU core with 136 basic instructions, 1–3 byte instruction length, and hardware support for multiplication/division and bit manipulation. Its clock system integrates selectable main oscillation (up to 16.25 MHz), external clock (32.5 MHz), and main CR clock (4–16 MHz via PLL multiplication), plus suboscillation (32.768 kHz) or sub-CR (50–150 kHz) sources.

Peripheral integration includes two 8/16-bit composite timers (configurable as 8-bit ×2 or 16-bit ×1), one time-base timer, one watch prescaler, full-duplex LIN-UART with double buffer and synchronous/asynchronous serial transfer, six external interrupt channels with edge-selectable wake-up, and on-chip debug via 1-wire serial control.

FAQ

What is the maximum operating frequency of the CY95F564KNPF-G-UNE2?

The device supports a maximum machine clock frequency of 16.25 MHz, achievable when using an external clock source up to 32.5 MHz with 2× division. At this speed, minimum instruction execution time is 61.5 ns, and interrupt processing time is 0.6 µs - enabling deterministic real-time response for automotive control loops.

Does CY95F564KNPF-G-UNE2 support LIN 2.2 or later specifications?

Yes - the integrated LIN-UART supports full LIN 2.2 compliance including master/slave operation, auto-baud detection, checksum calculation (classic/enhanced), and frame scheduling via reload timer. It meets ISO 17987-4 physical layer timing requirements when paired with a standard LIN transceiver.

How is Flash memory security implemented on this MCU?

Flash security is enforced via a dedicated lock bit that disables external read access through the on-chip debug interface. Once programmed, the Flash content cannot be extracted via serial programming or debug probes - protecting firmware IP and preventing unauthorized cloning in automotive ECU deployments.

What packaging and thermal characteristics apply to the WNP032 package?

The WNP032 (wettable flank QFN) package measures 5 mm × 5 mm with 0.5 mm pitch and features exposed thermal pad. Its θ_JA is 42°C/W on 2-layer PCB with 1-in² copper pour, enabling continuous operation up to 105°C ambient in automotive under-hood applications when properly mounted and heatsinked.
