FAQ

What is the maximum operating frequency of the CY95F778LPMC1-G-UNE2?

The CY95F778LPMC1-G-UNE2 supports a maximum machine clock frequency of 16.25 MHz, achievable using either the main PLL clock or an external clock input. At this frequency, the F2MC-8FX core achieves a minimum instruction execution time of 61.5 ns. The main oscillation clock is rated up to 16.25 MHz, and the external clock input accepts signals up to 32.5 MHz, with internal division applied to derive the machine clock.

Does the CY95F778LPMC1-G-UNE2 support in-system programming (ISP)?

Yes, the CY95F778LPMC1-G-UNE2 supports in-system programming via its on-chip debug interface using 1-wire serial control. It enables asynchronous serial writing to Flash memory without removing the device from the target board. Programming requires the dedicated debug pin (DBG) and compatible Cypress/Infineon programming tools such as the MiniProg3 or KitProg2, with no external high-voltage supply needed.

How many LCD segments and commons does this MCU support?

The CY95F778LPMC1-G-UNE2 supports two LCD configurations: 32 SEG × 4 COM (128 pixels) or 28 SEG × 8 COM (224 pixels). This is implemented through dedicated SEG0–SEG27 and COM0–COM7 pins. The internal divider resistor value (10 kΩ or 100 kΩ) is software-selectable to optimize contrast across varying supply voltages and ambient temperatures.

Is there a built-in low-voltage detection (LVD) circuit in this device?

No, the CY95F778LPMC1-G-UNE2 does not include a built-in low-voltage detection circuit. LVD functionality is present only on the "E" variants (e.g., CY95F778E), not the "L" series. The "L" suffix indicates the absence of LVD, making this variant suitable for applications where external supervision or fixed-supply operation eliminates the need for on-chip brown-out protection.
