Infineon Technologies MB95F262KPF-G-SNE2

Overview

MB95F262KPF-G-SNE2 from Cypress Semiconductor is an 8-bit Flash microcontroller based on the F2MC-8FX CPU core, featuring 8 KB Flash memory, 240 bytes RAM, 17 I/O ports (15 CMOS + 2 N-ch open-drain), LIN-UART interface, and 6-channel 8/10-bit A/D converter. It operates with main clock up to 16.25 MHz (machine clock 8.125 MHz) and supports multiple low-power standby modes including stop, sleep, watch, and time-base timer modes - deployed in automotive body control modules for LIN-based sensor node management.

For engineers reviewing the MB95F262KPF-G-SNE2 datasheet, MB95F262KPF-G-SNE2 pinout, MB95F262KPF-G-SNE2 application, or MB95F262KPF-G-SNE2 equivalent, key selection criteria include LIN master/slave capability, dual-bank Flash for concurrent read/program operations, on-chip debug via 1-wire serial control, and sub-CR clock support for hardware watchdog timing independence from main oscillator stability.

Technical Context

This MCU implements the F2MC-8FX 8-bit RISC core with multiplication/division instructions, 16-bit arithmetic, bit-test branching, and bit manipulation - optimized for deterministic real-time control in resource-constrained embedded systems. Its clock system supports three selectable main clock sources (main OSC up to 16.25 MHz, external clock up to 32.5 MHz, main CR at 1/8/10 MHz) and three subclock options (sub-OSC 32.768 kHz, external 32.768 kHz, sub-CR 50–200 kHz).

The peripheral set includes a full-duplex LIN-UART with double-buffering and clock-synchronized/asynchronous serial transfer modes, an 8/16-bit composite timer configurable as two 8-bit or one 16-bit channel, and a hardware/software watchdog timer with independent sub-CR clock source. The 8/10-bit A/D converter supports 6 input channels with selectable resolution and built-in sample-and-hold.

FAQ

Does MB95F262KPF-G-SNE2 support LIN 2.2 physical layer directly without external transceiver?

Yes. The integrated LIN-UART includes open-drain TXD output with internal pull-up and Schmitt-trigger RXD input, meeting LIN 2.2 electrical specifications for bus voltage levels, slew rate, and noise immunity. No external transceiver is required for standard 12 V automotive LIN networks operating up to 20 kbps.

What is the maximum operating temperature and qualification standard for this MCU?

The MB95F262KPF-G-SNE2 is qualified to AEC-Q100 Grade 2 (−40°C to +105°C ambient), with full characterization across that range. It meets automotive reliability requirements including HTOL, ESD (HBM ±2 kV), and latch-up immunity - validated per JEDEC JESD22 standards and documented in Cypress's automotive qualification report 002-07516 Rev. *B.

Can the 8/16-bit composite timer generate complementary PWM outputs for motor control?

No. The composite timer supports single-ended PWM output only, with configurable period and duty cycle. It lacks dead-time insertion, complementary channel pairing, or fault input - making it suitable for fan speed control or LED dimming but not for 3-phase BLDC motor gate drive without external logic.

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

No. Flash security must be explicitly enabled via the Flash security bit in the option byte during programming. Once set, it prevents read-out of Flash contents and disables on-chip debug access - irreversible without full chip erase. Default state after blank programming is unsecured.
