FAQ

What is the maximum operating frequency of the UPD78F0514AGAA-GAM-E2-G?

The UPD78F0514AGAA-GAM-E2-G supports a maximum CPU clock frequency of 20 MHz. This can be achieved using either the internal high-speed oscillator or an external crystal/resonator connected to the X1/X2 pins. At 20 MHz, the instruction cycle time is 0.05 μs for single-cycle instructions, enabling fast real-time response in control loops and communication protocols.

Does the UPD78F0514AGAA-GAM-E2-G include a hardware real-time clock (RTC)?

Yes, the UPD78F0514AGAA-GAM-E2-G includes a dedicated on-chip real-time clock (RTC) with calendar function supporting year/month/day/hour/minute/second. It operates using the sub-clock oscillator (32.768 kHz) and retains timekeeping in STOP mode with ≤1 μA current draw. This eliminates the need for external RTC ICs in time-critical embedded applications.

What package type and pin count does the UPD78F0514AGAA-GAM-E2-G use?

The UPD78F0514AGAA-GAM-E2-G uses a 64-pin LQFP package (10 mm × 10 mm, 0.5 mm pitch) with an exposed thermal pad. This package is mechanically and electrically identical to other 78K0/KC2 variants such as UPD78F0513AGAA-GAM-E2-G, enabling PCB layout reuse across family members with compatible memory requirements.

Can the UPD78F0514AGAA-GAM-E2-G perform in-system programming of its Flash memory?

Yes, the UPD78F0514AGAA-GAM-E2-G supports in-system programming (ISP) of its 64 KB on-chip Flash memory using the on-chip self-programming library. No external programmer is required - firmware updates can be performed via UART or other serial interface using user-developed bootloader code compliant with Renesas Application Note U17516E.

What is the A/D converter resolution and channel count on the UPD78F0514AGAA-GAM-E2-G?

The UPD78F0514AGAA-GAM-E2-G features a 10-bit successive-approximation A/D converter with 8 input channels. Conversion time is 1.2 μs (typical) at 20 MHz CPU clock. Input channels are multiplexed across Port 0 (P00–P03), Port 1 (P10–P13), and Port 2 (P20–P21), allowing flexible analog signal routing without external multiplexers.
