Product details
Overview
UPD78F0514AGAA-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 maximum operating frequency of 20 MHz. It integrates a 10-bit A/D converter with 16 channels, UART/SIO, I²C, and timer modules including 16-bit reload timers and watchdog timer. It targets embedded control applications such as industrial sensors and motor drive interfaces.
For engineers reviewing the UPD78F0514AGAA-GAM-G datasheet, UPD78F0514AGAA-GAM-G pinout, UPD78F0514AGAA-GAM-G application, or UPD78F0514AGAA-GAM-G equivalent, key selection criteria include Flash endurance (100,000 write/erase cycles), A/D conversion time (1.1 μs typical), operating voltage range (2.7–5.5 V), and support for on-chip self-programming via dedicated library.
Technical Context
The UPD78F0514AGAA-GAM-G implements the 78K0 CPU core with 16-bit address space and supports both conventional- and expanded-specification modes. Its peripheral set includes three 16-bit reload timers (TMRh/TMRl), one 8-bit interval timer, and a 16-bit real-time clock timer with calendar function.
It features dual power domains (VDD/EVDD) for analog/digital separation, AVREF/AVSS pins for A/D reference, and FLMD0 pin for boot mode selection. The device supports two oscillator configurations: high-speed (X1, 1–20 MHz) and sub-clock (32.768 kHz) for RTC operation.

FAQ
What is the maximum operating frequency of the UPD78F0514AGAA-GAM-G?
The UPD78F0514AGAA-GAM-G supports a maximum system clock frequency of 20 MHz when using an external crystal or ceramic resonator connected to the X1/X2 pins. This frequency enables a 1-μs instruction cycle time for most instructions, supporting real-time control tasks in motor drives and sensor systems. The device also supports sub-clock operation at 32.768 kHz for RTC functions independent of the main clock domain.
Does the UPD78F0514AGAA-GAM-G include a real-time clock (RTC)?
Yes, the UPD78F0514AGAA-GAM-G integrates a 16-bit real-time clock timer with calendar function, capable of tracking year, month, day, hour, minute, and second. It operates from a dedicated 32.768 kHz sub-clock oscillator, allowing accurate timekeeping during low-power STOP mode. The RTC includes alarm interrupt capability and supports leap-year correction in firmware.
How many A/D input channels does the UPD78F0514AGAA-GAM-G support?
The UPD78F0514AGAA-GAM-G features a 10-bit successive-approximation A/D converter with 16 selectable input channels. These channels are mapped across multiple ports (e.g., P20–P27, P40–P47), enabling simultaneous sampling of analog sensors such as temperature, voltage, and current. Conversion time is 1.1 μs at 20 MHz system clock, supporting up to ~900 kSPS aggregate throughput.
Is the UPD78F0514AGAA-GAM-G pin-compatible with other 78K0/KC2 devices?
Yes, the UPD78F0514AGAA-GAM-G shares the same 64-pin LQFP package and pin assignment with other 78K0/KC2 family members including UPD78F0511AGAA-GAM-G through UPD78F0515AGAA-GAM-G. This enables hardware reuse across variants differing only in Flash size (64 KB vs. 96 KB) and minor peripheral configuration-facilitating scalable design and migration paths without PCB redesign.
What development tools are supported for the UPD78F0514AGAA-GAM-G?
The UPD78F0514AGAA-GAM-G is fully supported by Renesas' legacy 78K0 toolchain, including the RA78K0 assembler (Ver. 4.01), CC78K0 C compiler (Ver. 4.00), QB-MINI2 on-chip debug emulator, and PM+ IDE. Flash programming is enabled via PG-FP5 programmer or on-chip self-programming using Renesas' supplied library (U17516E). Application notes U17739E and U17517E provide detailed guidance on Flash and EEPROM emulation implementation.
