Technical Context

The UPD78F1515AGC(R)-UEU-M1-AX implements the 78K0R CPU core with 16-bit architecture, Harvard memory organization, and instruction set compatible with earlier 78K0 devices. It integrates a 16-bit timer array unit (TAU) with capture/compare, watchdog timer (WDT), and real-time clock (RTC) with calendar function.

Peripheral integration includes a 10-bit ADC with sample-and-hold, programmable gain amplifier (PGA), and dual DAC outputs. The device supports multiple low-power modes (HALT, STOP, SNOOZE) and features a dedicated voltage regulator (REGC) for stable internal core voltage independent of VDD fluctuations.

FAQ

What is the maximum operating frequency of the UPD78F1515AGC(R)-UEU-M1-AX?

The UPD78F1515AGC(R)-UEU-M1-AX supports a maximum system clock frequency of 20 MHz when driven by an external crystal oscillator or the internal high-speed oscillator. This frequency is sustained across the full operating voltage range (2.7–5.5 V) and ambient temperature range (−40°C to +85°C), enabling deterministic real-time execution for motor control and metering algorithms.

Does the UPD78F1515AGC(R)-UEU-M1-AX include an integrated voltage regulator?

Yes, the UPD78F1515AGC(R)-UEU-M1-AX includes an on-chip voltage regulator controlled via the REGC pin. When enabled, it generates a stable 1.8 V core supply from the main VDD rail, reducing dependency on external LDOs and improving noise immunity in mixed-signal applications. A 10 μF ceramic capacitor must be connected to REGC for loop stability.

How many analog-to-digital converter channels does the UPD78F1515AGC(R)-UEU-M1-AX support?

The UPD78F1515AGC(R)-UEU-M1-AX supports 24 analog input channels for its 10-bit successive approximation ADC. These channels are distributed across Ports 2–5 (AD00–AD23) and can be selected dynamically via the ADPC register, allowing flexible sensor routing without hardware reconfiguration.

Can the UPD78F1515AGC(R)-UEU-M1-AX drive an LCD display directly?

Yes, the UPD78F1515AGC(R)-UEU-M1-AX integrates a static/dynamic LCD controller supporting up to 32 segments and 8 commons. It provides dedicated SEGxx and COMxx output pins plus VLC0–VLC3 bias voltage control, enabling direct connection to segment-type LCDs without external driver ICs in applications like energy meters and appliance displays.

What debug tools are compatible with the UPD78F1515AGC(R)-UEU-M1-AX?

The UPD78F1515AGC(R)-UEU-M1-AX is fully supported by Renesas' QB-MINI2 on-chip debug emulator and QB-78K0RLX3 in-circuit emulator. Both tools provide real-time debugging, flash programming, and trace capabilities through the standard 10-pin debug interface defined in the 78K0R/LG3 hardware manual.
