Infineon Technologies MB95F263KPFT-G-SNE2

Overview

MB95F263KPFT-G-SNE2 from Cypress Semiconductor is an 8-bit Flash microcontroller in the MB95260H series featuring the F2MC-8FX CPU core, 12 KB on-chip Flash memory, 496 bytes RAM, and LIN-UART interface. It supports dual-bank Flash operation, hardware/software watchdog timers, and operates with main clock frequencies up to 16.25 MHz (machine clock) for real-time control in automotive body electronics.

For engineers reviewing the MB95F263KPFT-G-SNE2 datasheet, MB95F263KPFT-G-SNE2 pinout, MB95F263KPFT-G-SNE2 application, or MB95F263KPFT-G-SNE2 equivalent, key selection criteria include its 17-pin I/O count (15 CMOS + 2 N-ch open-drain), 8/10-bit ADC with 6 channels, 8/16-bit composite timer, and LIN master/slave capability in a 20-pin TSSOP package.

Technical Context

This MCU implements the F2MC-8FX core with 136 basic instructions, 1–3 byte instruction length, and support for 1-/8-/16-bit data operations. Its clock system includes selectable main sources (main OSC up to 16.25 MHz, external clock up to 32.5 MHz, or main CR at 1/8/10 MHz) and subclock options (32.768 kHz OSC, external, or 50–200 kHz sub-CR).

The device integrates LIN-UART with full-duplex double buffering, enabling both clock-synchronized and asynchronous serial transfer. It supports wake-up from Stop/Sleep/Watch/Time-base timer modes via edge-triggered external interrupts (6 channels), and features dual-operation Flash with 100,000 program/erase cycles and 20-year data retention.

FAQ

What is the maximum operating frequency of the MB95F263KPFT-G-SNE2?

The device supports a maximum external clock input of 32.5 MHz, yielding a maximum machine clock frequency of 16.25 MHz. This is achieved using the external clock source option; with main OSC, max machine clock is 8.125 MHz. All timing specifications in the datasheet are validated at 16.25 MHz machine clock.

Does MB95F263KPFT-G-SNE2 support in-system programming via LIN-UART?

No - in-system programming requires the dedicated TEST pin and 1-wire serial debug interface. LIN-UART supports only application-level data communication; it cannot be used for Flash programming. The on-chip debug controller mandates TEST pin activation and proprietary command sequence.

How many LIN nodes can be addressed using the built-in LIN-UART?

The LIN-UART itself does not assign node addresses; address handling is implemented in firmware. The peripheral supports standard LIN 2.2 frame formatting and checksum calculation, enabling implementation of up to 16 slave nodes (per LIN specification) when paired with appropriate physical layer transceivers and master arbitration logic.

Is the Flash memory security feature enabled by default after programming?

No - Flash security must be explicitly enabled via dedicated security register write during programming. Once activated, it prevents read-out of Flash contents and disables debug access via TEST pin. Disabling requires full chip erase; no backdoor or override mechanism exists per design.
