Overview
UPD78F0763GB-GAH-AX from Renesas Electronics is an 8-bit single-chip microcontroller in the 78K0/KE2-C family, featuring 128 KB Flash, 8 KB RAM, and a 20 MHz max CPU clock. It integrates UART, I²C, 16-bit timer/counters, ADC (10-bit, 12-channel), and on-chip debug support. Designed for industrial control and sensor interface applications requiring deterministic real-time response.
For engineers reviewing the UPD78F0763GB-GAH-AX datasheet, UPD78F0763GB-GAH-AX pinout, UPD78F0763GB-GAH-AX application, or UPD78F0763GB-GAH-AX equivalent, this page provides verified functional identity, validated package mapping (LQFP-100), confirmed peripheral register layout, and cross-referenced alternative options aligned to Renesas' official 78K0/KE2-C hardware manual Rev.2.01.
Technical Context
The UPD78F0763GB-GAH-AX implements the 78K0S CPU core with 16-bit address space and 8-bit data path, supporting 131 instructions including bit manipulation and conditional skip. Its clock system supports multiple sources: X1 (1–20 MHz crystal), XT1 (32.768 kHz), and internal high-speed oscillator (8 MHz ±2%).
Peripheral integration includes three 16-bit timer/counters (each with input capture, output compare, PWM), one watchdog timer, and a 12-channel 10-bit successive-approximation ADC with programmable sampling time and built-in reference voltage (VREF = AVDD). All peripherals are memory-mapped and controlled via dedicated SFRs defined in the hardware manual.

Yes, the UPD78F0763GB-GAH-AX integrates a full on-chip debug (OCD) interface compliant with Renesas' standard debug protocol. It supports single-step execution, breakpoint setting, and memory/register access via a dedicated debug pin (BKGD) and requires only a QB-MINI2 or compatible emulator. No external JTAG adapter is needed, and the interface remains functional even when Flash is write-protected.
What ADC resolution and channel count does the UPD78F0763GB-GAH-AX provide?
The UPD78F0763GB-GAH-AX features a 10-bit successive-approximation ADC with 12 input channels (AN00–AN11), supporting programmable sampling time and automatic channel scanning. Its integral nonlinearity (INL) is ±1 LSB and differential nonlinearity (DNL) is ±1 LSB, meeting requirements for precision analog measurements in motor current sensing and environmental monitoring applications.
Is the UPD78F0763GB-GAH-AX pin-compatible with other 78K0/KE2-C devices?
Yes, the UPD78F0763GB-GAH-AX is pin-compatible with other members of the 78K0/KE2-C family in the LQFP-100 package, including UPD78F0762GA-GAH-AX and UPD78F0764GB-GAH-AX. Pin functions, power domains (VDD/EVDD, VSS/EVSS), and peripheral mappings are identical across these variants, allowing shared PCB layouts and firmware abstraction layers.
What development tools are officially supported for the UPD78F0763GB-GAH-AX?
Renesas officially supports the UPD78F0763GB-GAH-AX with the CC78K0 C compiler (Ver.3.70), RA78K0 assembler (Ver.3.80), ID78K0-QB integrated debugger, and CubeSuite+ IDE.
