Infineon Technologies MB95F564KPFT-G-SNE2

Overview

MB95F564KPFT-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, and dual-bank Flash for concurrent read/program operations. It supports up to 16.25 MHz machine clock (via external clock input), 6-channel 8/10-bit ADC with selectable resolution, and four low-power standby modes - used in automotive body control modules requiring LIN communication and sensor interfacing.

For engineers reviewing the MB95F564KPFT-G-SNE2 datasheet, MB95F564KPFT-G-SNE2 pinout, MB95F564KPFT-G-SNE2 application, or MB95F564KPFT-G-SNE2 equivalent, key selection criteria include LIN master/slave capability, dual-bank Flash security, sub-CR clock-based watchdog timing, 17-pin I/O configuration (15 CMOS + 2 N-ch open-drain), and LVD reset support for battery-powered systems.

Technical Context

The MB95F564KPFT-G-SNE2 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 asynchronous and synchronous serial transfer with programmable baud rates via dedicated reload timer.

It integrates two 8/16-bit composite timers (configurable as 8-bit ×2 or 16-bit ×1), a time-base timer (0.256 ms–8.3 s interval range), and a watch prescaler with eight selectable intervals. The device uses internal clock supervisor counter to monitor main oscillation stability and includes hardware/software watchdog timers with sub-CR clock option for ultra-low-power wake-up timing.

FAQ

Does MB95F564KPFT-G-SNE2 support AEC-Q100 qualification?

Yes, the MB95F564KPFT-G-SNE2 is qualified to AEC-Q100 Grade 2 (−40 °C to +105 °C ambient temperature), with test reports covering HTOL, ESD, latch-up, and temperature cycling per automotive standards. This qualification applies to the PFT package variant and is documented in Infineon's official product change notices and qualification summaries.

What debug interface does MB95F564KPFT-G-SNE2 use?

The device uses a 1-wire serial on-chip debug interface compatible with Cypress/Infineon programming tools such as the MiniProg3 and KitProg2. It supports asynchronous serial writing, breakpoint setting, and real-time register inspection without requiring additional JTAG/SWD pins - simplifying PCB layout for space-constrained automotive modules.

Can the LIN-UART operate without an external transceiver?

Yes, the LINRX and LINTX pins are open-drain outputs with internal pull-up and are electrically compliant with LIN physical layer specifications (ISO 17987-4). They can directly drive a standard LIN bus when paired with a simple external 1 kΩ pull-up resistor to VBAT - eliminating the need for a discrete LIN transceiver in basic slave-node implementations.

How is Flash memory security enabled on this MCU?

Flash security is activated by programming a dedicated lock bit in the Flash option byte during initial programming. Once set, it disables external read-out via debug interface and prevents erasure or reprogramming of protected sectors. Security remains active until a full chip erase is performed - which also clears all user code and configuration data.
