FAQ

What is the maximum operating frequency of the MB95F478KPMC1-G-SNE2?

The MB95F478KPMC1-G-SNE2 supports a maximum machine clock frequency of 16.25 MHz, achievable using the main PLL clock or external clock source. At this frequency, minimum instruction execution time is 61.5 ns, and interrupt processing time is 0.6 µs - enabling responsive real-time control in display-driven applications.

Does the MB95F478KPMC1-G-SNE2 support in-system programming?

Yes - the device supports asynchronous serial programming via its 1-wire on-chip debug interface. This allows firmware updates without removing the MCU from the PCB, using standard UART-level signals and Cypress's proprietary protocol for flash programming and verification.

How many LCD bias voltage pins does the MB95F478KPMC1-G-SNE2 provide?

The MB95F478KPMC1-G-SNE2 provides up to four LCD bias voltage pins (VB1–VB4), matching its maximum 8-COM LCD configuration. These pins connect to external resistive divider networks or integrated LCD bias generators to establish proper segment-to-common voltage ratios for clear display contrast.

Can the MB95F478KPMC1-G-SNE2 operate from a single 3.3 V supply?

Yes - the device operates across 2.7 V to 5.5 V, making it compatible with both 3.3 V and 5 V systems. At 3.3 V, all peripherals including LCD driver, ADC, and UART remain fully functional; however, maximum machine clock frequency is reduced to 12.5 MHz when using main CR clock at 12.5 MHz.
