Infineon Technologies MB95F478KPMC2-G-SNE2

Overview

MB95F478KPMC2-G-SNE2 from Cypress Semiconductor is an 8-bit F2MC-8FX microcontroller with 60 KB Flash, 2032 bytes RAM, 59 I/O ports (55 CMOS + 4 N-ch open-drain), 3-channel UART/SIO, and integrated LCD controller supporting up to 28 SEG × 8 COM (224-pixel) drive. It operates at up to 16.25 MHz machine clock using main PLL or external clock sources and targets embedded control in industrial HMI and appliance displays.

For engineers reviewing the MB95F478KPMC2-G-SNE2 datasheet, MB95F478KPMC2-G-SNE2 pinout, MB95F478KPMC2-G-SNE2 application, or MB95F478KPMC2-G-SNE2 equivalent, key selection criteria include its dual-bank Flash architecture enabling concurrent read/program operations, software-selectable 8/10-bit ADC resolution across 8 channels, and hardware/software watchdog timers with sub-CR clock source support for robust low-power system supervision.

Technical Context

The MB95F478KPMC2-G-SNE2 implements the F2MC-8FX CPU core with 136 basic instructions, 1–3 byte instruction length, and 61.5 ns minimum execution time at 16.25 MHz. It integrates a clock supervisor counter to monitor main clock oscillation stability and supports four standby modes-stop, sleep, watch, and time-base timer-with wake-up via edge-triggered external interrupts on eight channels.

Its peripheral set includes two 8/16-bit composite timers (configurable as 8-bit ×2 or 16-bit ×1), two 8/16-bit PPG channels, one 16-bit reload timer, one event counter, one time-base timer (0.256 ms–8.3 s range), and one I²C master/slave interface with bus error detection and arbitration. The LCD controller provides programmable bias resistor (10 kΩ or 100 kΩ), frame-sync interrupt, blinking, and inverted display functions.

FAQ

What is the maximum operating frequency of the MB95F478KPMC2-G-SNE2?

The MB95F478KPMC2-G-SNE2 supports a maximum machine clock frequency of 16.25 MHz, achievable using the main PLL clock or an external clock source up to 32.5 MHz. This corresponds to a minimum instruction execution time of 61.5 ns and enables real-time response for time-critical peripherals like UART and PWM.

Does this MCU support in-system programming without removing it from the board?

Yes, the MB95F478KPMC2-G-SNE2 supports in-system programming via its 1-wire serial debug interface in asynchronous mode. This allows firmware updates and debugging directly on the target PCB without requiring socketing or external programmers, reducing manufacturing and service overhead.

How many LCD segments and commons can be driven, and what bias options are available?

The MCU supports LCD configurations up to 28 SEG × 8 COM (224 pixels). Bias resistor value is software-selectable between 10 kΩ and 100 kΩ, allowing dynamic contrast adjustment based on temperature, supply voltage, or display type without external components.

Is there hardware support for detecting main clock failure?

Yes, the MB95F478KPMC2-G-SNE2 includes a built-in clock supervisor counter that actively monitors main clock oscillation stability. If oscillation stops or falls outside tolerance, it triggers a reset-ensuring deterministic recovery in safety-critical or unattended operation scenarios.
