Renesas UPD78F0515AGAA-GAM-G

Overview

UPD78F0515AGAA-GAM-G from Renesas Electronics is an 8-bit single-chip microcontroller in the 78K0/KC2 family, featuring 64 KB on-chip flash memory, 4 KB RAM, and a 16-bit timer/counter with PWM output capability. It operates at up to 20 MHz using an external crystal or internal high-speed oscillator and supports 5V operation for industrial control applications including motor drive interfaces and sensor-based embedded systems.

For engineers reviewing the UPD78F0515AGAA-GAM-G datasheet, UPD78F0515AGAA-GAM-G pinout, UPD78F0515AGAA-GAM-G application, or UPD78F0515AGAA-GAM-G equivalent, key selection criteria include its 64-pin LQFP package, 10-bit A/D converter with 16 channels, serial interface options (UART, CSI, I²C), and integrated watchdog timer with window function.

Technical Context

The UPD78F0515AGAA-GAM-G implements the 78K0 CPU core with 16-bit addressing, supporting 131 instructions and a 1- to 4-cycle execution time. Its peripheral set includes a 16-bit reload timer (RTU), 16-bit interval timer (IT), and a 16-bit real-time clock (RTC) with calendar function.

It integrates a 10-bit successive-approximation A/D converter with sample-and-hold circuitry, programmable conversion start triggers (software, timer, external pin), and built-in reference voltage (AVREF) input. The device also features dual voltage regulators: one for core logic (1.8 V) and another for I/O (5 V), enabling mixed-voltage operation.

FAQ

What is the maximum operating frequency of the UPD78F0515AGAA-GAM-G?

The UPD78F0515AGAA-GAM-G supports a maximum system clock frequency of 20 MHz when driven by an external crystal connected to X1/X2 pins. It also allows use of the internal high-speed oscillator (HSO) at 20 MHz without external components, though with ±2% accuracy over temperature and voltage. This frequency determines instruction execution speed, A/D conversion rate, and PWM resolution limits in real-time control applications.

Does the UPD78F0515AGAA-GAM-G include a hardware real-time clock (RTC)?

Yes, the UPD78F0515AGAA-GAM-G integrates a full-featured 16-bit real-time clock with calendar function supporting year/month/day/hour/minute/second counting and alarm generation. It operates from a dedicated 32.768 kHz sub-clock (X2 input) and retains time during STOP mode when backed by VBAT. This eliminates need for external RTC ICs in time-critical embedded applications such as data loggers and appliance timers.

How many A/D input channels does the UPD78F0515AGAA-GAM-G support?

The UPD78F0515AGAA-GAM-G features a 10-bit successive-approximation A/D converter with 16 selectable analog input channels (AN0–AN15), mapped across ports P1, P2, and P12. Each channel supports software, timer-triggered, or external pin-triggered conversion starts, and the result is stored in a 16-word result register array - enabling rapid sequential sampling for sensor fusion or motor phase current monitoring.

Is the UPD78F0515AGAA-GAM-G pin-compatible with other 78K0/KC2 microcontrollers?

Yes, the UPD78F0515AGAA-GAM-G shares the same 64-pin LQFP package and pin assignment with other 78K0/KC2 devices including UPD78F0513AGAA-GAM-G and UPD78F0511AGAA-GAM-G. Pin functions for power, reset, clocks, and all I/O ports are identical across this family, allowing hardware reuse and migration paths based on flash size, RAM, or peripheral configuration requirements without PCB redesign.

What low-power modes are supported by the UPD78F0515AGAA-GAM-G?

The UPD78F0515AGAA-GAM-G implements four low-power operating modes: HALT (CPU stopped, peripherals active), STOP (CPU and most peripherals halted, RTC and WDT running), IDLE (CPU halted, selected peripherals active), and SNOOZE (peripheral-triggered wake-up with minimal latency). In STOP mode, current consumption drops to 1.2 μA at 5 V and 25°C - enabling energy-efficient operation in battery-powered or thermally constrained designs.
