It operates at up to 20 MHz with supply voltage range of 2.7 V to 5.5 V and targets embedded control in industrial sensors and motor drive interfaces.

For engineers reviewing the UPD78F1011GK(R)-GAK-AX datasheet, UPD78F1011GK(R)-GAK-AX pinout, UPD78F1011GK(R)-GAK-AX application, or UPD78F1011GK(R)-GAK-AX equivalent, key selection considerations include Flash endurance (100,000 write/erase cycles), operating temperature range (−40°C to +85°C), and compatibility with Renesas' QB-78K0RKX3C in-circuit emulator for debug and programming.

Technical Context

The UPD78F1011GK(R)-GAK-AX implements the 78K0R CPU core with 16-bit architecture, supporting 16-MHz maximum operation via internal high-speed oscillator or external crystal (1–20 MHz). It integrates dual voltage domains (EVDD0/EVSS0 for analog peripherals; VDD/VSS for digital logic) and features programmable low-voltage detection (LVD) with 12 selectable thresholds between 1.6 V and 4.2 V.

Its peripheral set includes three 16-bit timer arrays (each with capture/compare/PWM output), a watchdog timer with independent clock source, and hardware multiplier/divider unit. The device supports in-application programming (IAP) using on-chip Flash with sector erase granularity and supports secure boot via ROM-based bootloader.

FAQ

What is the maximum operating frequency of the UPD78F1011GK(R)-GAK-AX?

The UPD78F1011GK(R)-GAK-AX supports a maximum CPU clock frequency of 20 MHz, achievable using either the internal high-speed oscillator (with trimming) or an external crystal/resonator up to 20 MHz. This frequency enables deterministic real-time response for motor control and sensor processing tasks while maintaining low power consumption at lower operating speeds.

Does the UPD78F1011GK(R)-GAK-AX support in-system programming (ISP)?

Yes, the UPD78F1011GK(R)-GAK-AX supports in-application programming (IAP) via its on-chip Flash memory. Using the built-in ROM bootloader or user-implemented firmware routines, the UPD78F1011GK(R)-GAK-AX can reprogram its own Flash sectors without requiring external programming hardware - enabling field firmware updates and configuration storage.

What are the analog voltage supply requirements for the UPD78F1011GK(R)-GAK-AX ADC?

The UPD78F1011GK(R)-GAK-AX requires separate analog supplies: EVDD0 and EVSS0 must be connected to clean, low-noise sources. EVDD0 powers the ADC, PGA, and comparators; it must be within 2.7–5.5 V and decoupled with ≥1 μF ceramic capacitor close to the pin. AVREF sets the ADC reference and may be internal (2.5 V) or external (1.0–5.5 V).

Is the UPD78F1011GK(R)-GAK-AX pin-compatible with other devices in the 78K0R/KF3-L family?

Yes, the UPD78F1011GK(R)-GAK-AX shares identical 64-pin LQFP pinout and electrical characteristics with other 78K0R/KF3-L devices including UPD78F1010GK(R)-GAK-AX and UPD78F1012GK(R)-GAK-AX. This allows direct substitution within the same package variant, provided firmware and Flash size requirements align with the target device.

What debug tools are officially supported for the UPD78F1011GK(R)-GAK-AX?

The UPD78F1011GK(R)-GAK-AX is fully supported by the QB-78K0RKX3C in-circuit emulator, which provides real-time debugging, flash programming, and trace capabilities. It is also compatible with the RA78K0R assembler and CC78K0R C compiler toolchain, and integrates with Renesas' e² studio IDE for seamless development workflow.
