Infineon Technologies MB95F354EPFT-G-SNE2

Overview

MB95F354EPFT-G-SNE2 from Cypress Semiconductor is an 8-bit F2MC-8FX microcontroller with 20 KB Flash, 496 bytes RAM, 22 I/O ports (18 CMOS, 3 N-ch open drain, 1 CMOS input), 6-channel 8/10-bit ADC, dual I²C, LIN-UART, and 2× 8/16-bit composite timers. It operates at up to 16.25 MHz machine clock using external clock source and targets embedded control in industrial sensors and motor drive interfaces.

For engineers reviewing the MB95F354EPFT-G-SNE2 datasheet, MB95F354EPFT-G-SNE2 pinout, MB95F354EPFT-G-SNE2 application, or MB95F354EPFT-G-SNE2 equivalent, key selection factors include Flash banked dual-operation capability, LIN-UART master/slave support, sub-CR clock-based watchdog timing, and 24-pin SOP package compatibility with on-chip debug via 1-wire serial interface.

Technical Context

The MB95F354EPFT-G-SNE2 implements the F2MC-8FX CPU core with 136 instructions, 8-bit data width, and 1–3 byte instruction length, enabling 61.5 ns minimum instruction execution at 16.25 MHz. Its interrupt system supports six external edge-selectable channels and delivers 0.6 µs latency under full clock speed.

Peripheral integration includes two configurable 8/16-bit composite timers with PWM, PWC, and input capture; one time-base timer with 0.256 ms–8.3 s range; and dual I²C channels-where one shares functionality with UART/SIO-supporting Standard-mode (100 kHz) and Fast-mode (400 kHz) operation with built-in wake-up.

FAQ

What debug interface does MB95F354EPFT-G-SNE2 support?

MB95F354EPFT-G-SNE2 supports 1-wire serial on-chip debug via pin P12/EC0/DBG. This interface enables asynchronous serial programming, real-time register inspection, and breakpoint control without requiring additional debug hardware or pins beyond the single debug line and standard VCC/VSS connections.

Does MB95F354EPFT-G-SNE2 support LIN 2.x protocol natively?

Yes-MB95F354EPFT-G-SNE2's LIN-UART peripheral supports LIN 2.x master and slave operation through dedicated reload timer control, automatic sync-break detection, and configurable baud rate generation. It handles both standard and extended checksum models and supports wakeup via dominant bus signal.

Can the ADC operate during low-power modes?

The ADC cannot convert in Stop mode but remains functional in Sleep, Watch, and Time-base timer modes. In Sleep mode, conversion completes in ~10 µs with typical current draw of 120 µA, enabling periodic sensor sampling without full wake-up, preserving overall system power efficiency.

What clock sources are available for the hardware watchdog timer?

The hardware watchdog timer supports two clock sources: the main oscillation clock (e.g., 10 MHz) for fast timeout (105 ms min), and the sub-CR clock (50–200 kHz) for ultra-low-power supervision during deep sleep. Selection is configured via dedicated control register bits at initialization.
