Overview
UPD78F1011GK(R)-GAK-M1-AX from Renesas Electronics is a 16-bit single-chip microcontroller in the 78K0R/KF3-L family, featuring 128 KB on-chip Flash memory, 8 KB RAM, and integrated peripherals including 10-bit ADC (16 channels), UART, I²C, and 16-bit timer arrays. It operates at up to 20 MHz with supply voltage range 2.7–5.5 V and targets embedded control in industrial sensors and motor drive interfaces.
For engineers reviewing the UPD78F1011GK(R)-GAK-M1-AX datasheet, UPD78F1011GK(R)-GAK-M1-AX pinout, UPD78F1011GK(R)-GAK-M1-AX application, or UPD78F1011GK(R)-GAK-M1-AX equivalent, key selection criteria include Flash endurance (100k write/erase cycles), operating temperature range (−40°C to +85°C), and compatibility with RA78K0R toolchain and QB-78K0RKX3C emulator.
Technical Context
The UPD78F1011GK(R)-GAK-M1-AX implements the 78K0R CPU core with 16-bit ALU, 24-bit address space, and Harvard architecture. It supports three power-saving modes - HALT, STOP, and SNOOZE - with wake-up via external interrupt or peripheral event. On-chip voltage regulator (REGC pin) enables single-supply operation from 2.7–5.5 V.
Peripheral integration includes a 16-channel, 10-bit successive-approximation ADC with programmable sampling time and conversion trigger sources (timer, external pin, software), plus dual UARTs with LIN support and two I²C interfaces supporting master/slave mode and 100/400 kHz rates.

FAQ
What is the maximum operating frequency of the UPD78F1011GK(R)-GAK-M1-AX?
The UPD78F1011GK(R)-GAK-M1-AX operates at a maximum CPU clock frequency of 20 MHz, achievable using the on-chip PLL or external crystal oscillator. This frequency is fully supported across the full −40°C to +85°C temperature range and 2.7–5.5 V supply voltage, enabling deterministic real-time response in industrial control loops.
Does the UPD78F1011GK(R)-GAK-M1-AX support in-circuit debugging?
Yes, the UPD78F1011GK(R)-GAK-M1-AX supports full in-circuit debugging via the on-chip debug interface compatible with the QB-78K0RKX3C emulator. It enables breakpoints, watchpoints, register inspection, and flash programming without requiring dedicated debug pins beyond the standard SWD/JTAG-compatible header.
What is the Flash endurance specification for the UPD78F1011GK(R)-GAK-M1-AX?
The UPD78F1011GK(R)-GAK-M1-AX guarantees 100,000 write/erase cycles per Flash sector and 10 years of data retention at +85°C. This endurance rating applies to all 128 KB of on-chip Flash memory and is validated under Renesas' industrial-grade qualification standards.
Can the UPD78F1011GK(R)-GAK-M1-AX operate from a single 3.3 V supply?
Yes, the UPD78F1011GK(R)-GAK-M1-AX operates reliably from a single 3.3 V supply. Its 2.7–5.5 V operating range allows direct connection to standard 3.3 V regulators, and the internal voltage regulator (controlled via REGC pin) can be disabled to use external 3.3 V for both digital and analog domains.
Which development tools are officially supported for the UPD78F1011GK(R)-GAK-M1-AX?
Renesas officially supports the RA78K0R assembler, CC78K0R C compiler (Ver. 2.00), ID78K0R-QB integrated debugger, and QB-78K0RKX3C in-circuit emulator for the UPD78F1011GK(R)-GAK-M1-AX. These tools are documented in User's Manual U18549E, U18548E, and U17839E respectively.
