Overview

MB95F564KPF-G-SNE2 from Infineon Technologies (formerly Cypress) 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 8/10-bit ADC with 6 channels. It operates at up to 16.25 MHz machine clock frequency and supports four low-power standby modes for automotive body electronics control.

For engineers reviewing the MB95F564KPF-G-SNE2 datasheet, MB95F564KPF-G-SNE2 pinout, MB95F564KPF-G-SNE2 application, or MB95F564KPF-G-SNE2 equivalent, key selection criteria include LIN bus master/slave capability, 17-pin I/O configuration (15 CMOS + 2 N-ch open-drain), on-chip debug via 1-wire serial control, and integrated low-voltage detection reset - all confirmed in the official Infineon MB95560H Series datasheet (Doc #002-04629 Rev. *E).

Technical Context

The MB95F564KPF-G-SNE2 implements the F2MC-8FX CPU core with 136 basic instructions, 1–3 byte instruction length, and support for 16-bit arithmetic, multiplication/division, and bit manipulation - enabling efficient real-time control in resource-constrained systems. Its clock system includes selectable main sources (main oscillation up to 16.25 MHz, external clock up to 32.5 MHz, or main CR clock at 4–16 MHz via PLL multiplication) and subclock options (32.768 kHz crystal or 50–150 kHz sub-CR).

It integrates a full-duplex LIN-UART with double-buffering, supporting both asynchronous serial communication and clock-synchronous transfer, and features dual 8/16-bit composite timers with PWM, input capture, and PWC functions - configurable per channel as either two 8-bit timers or one 16-bit timer using seven internal/external clock sources.

FAQ

What is the maximum operating frequency and corresponding machine cycle time for MB95F564KPF-G-SNE2?

The device supports an external clock input up to 32.5 MHz, yielding a maximum machine clock frequency of 16.25 MHz. At this rate, the minimum instruction execution time is 61.5 ns, verified in the datasheet's AC characteristics table (Section 24.4). This timing enables deterministic response for LIN frame processing and PWM generation with sub-microsecond jitter.

Does MB95F564KPF-G-SNE2 support LIN 2.2 physical layer compliance out-of-the-box?

Yes - the integrated LIN-UART supports LIN 2.2 protocol features including auto-baud rate detection, checksum calculation (classic/enhanced), and frame synchronization. However, physical layer compliance requires pairing with a certified LIN transceiver (e.g., TLE7259-2G); the MCU itself handles protocol stack execution and timing-critical bit sampling.

How many I/O pins support N-ch open-drain configuration, and what is their voltage tolerance?

Two I/O pins (P00 and P01) are configurable as N-ch open-drain outputs, rated for 5.5 V absolute maximum. These pins tolerate voltages beyond VDD and are intended for wired-AND bus interfaces, LED sinking, and driving external level shifters - confirmed in Section 10 "I/O Circuit Type" of the datasheet.

Is on-chip debug supported via SWD or JTAG, or only through the 1-wire interface?

Debug is exclusively supported via the 1-wire serial interface using the TEST pin; no SWD or JTAG is implemented. The interface enables flash programming, register inspection, and breakpoint insertion in asynchronous mode - documented in Section 14 "On-chip debug" and validated by Infineon's F2MC-8FX debug specification.
