Overview

MB95F378LPMC2-G-SNE2 from Cypress Semiconductor is an 8-bit Flash microcontroller in the MB95370L series featuring the F2MC-8FX CPU core, 60 KB Flash memory, 2032 bytes RAM, 55 I/O ports (52 CMOS + 3 N-ch open-drain), and integrated LCD controller supporting 32 SEG × 4 COM (128-pixel) display. It operates at up to 16.25 MHz machine clock using main PLL or external clock sources and targets embedded control applications with LCD interfaces, such as industrial HMIs and appliance panels.

For engineers reviewing the MB95F378LPMC2-G-SNE2 datasheet, MB95F378LPMC2-G-SNE2 pinout, MB95F378LPMC2-G-SNE2 application, or MB95F378LPMC2-G-SNE2 equivalent, key selection criteria include its 60 KB Flash capacity, dual UART/SIO channels with full-duplex double buffering, 4-channel 8/10-bit ADC, hardware/software watchdog timers, and low-power standby modes (stop/sleep/watch/time-base timer).

Technical Context

The MB95F378LPMC2-G-SNE2 implements the F2MC-8FX CPU core with 136 basic instructions, 1–3 byte instruction length, and support for 1-/8-/16-bit data operations. Its minimum instruction execution time is 61.5 ns at 16.25 MHz machine clock, and interrupt processing time is 0.6 µs under the same condition.

It integrates a 32 SEG × 4 COM LCD controller with internal divider resistors and blinking function, two UART/SIO channels supporting NRZ format, LSB/MSB-first transfer, and baud rate generation, plus one I²C channel with master/slave capability, bus error detection, and wake-up functionality.

FAQ

What is the maximum operating frequency of the MB95F378LPMC2-G-SNE2?

The MB95F378LPMC2-G-SNE2 achieves a maximum machine clock frequency of 16.25 MHz using the main PLL clock or external clock source. Its minimum instruction execution time is 61.5 ns at this speed, and the CPU supports 136 basic instructions with 1–3 byte encoding. The device also allows lower-frequency operation via main CR clock (1/8/10/12.5 MHz) for reduced power consumption.

Does the MB95F378LPMC2-G-SNE2 support in-system programming?

Yes, the MB95F378LPMC2-G-SNE2 supports in-system programming via its 1-wire on-chip debug interface operating in asynchronous serial mode. This enables firmware updates without removing the chip from the board, using standard UART-level signals and no additional debug headers. Flash programming uses Embedded Algorithm commands with completion flag reporting and supports up to 100,000 erase/program cycles.

How many LCD segments can the MB95F378LPMC2-G-SNE2 drive directly?

The MB95F378LPMC2-G-SNE2 drives up to 32 SEG × 4 COM (128 pixels) directly through its integrated LCD controller. It provides four COM outputs and 32 SEG outputs, internal voltage divider resistors for bias generation, and software-controllable blinking function. Unlike earlier MB95310L-series variants, it does not support 40 SEG configurations.

What low-power modes are available and how do they differ?

The MB95F378LPMC2-G-SNE2 offers four low-power standby modes: Stop mode halts CPU and most peripherals while retaining RAM and register contents; Sleep mode stops CPU but keeps peripherals active; Watch mode disables CPU and most clocks except watch counter; Time-base timer mode runs only the time-base timer. All modes support wake-up via external interrupt or timer event, with typical current draw ranging from 0.3 µA (Stop) to 10 µA (Time-base timer).
