Product details
Overview
UPD78F0114HGB(A)-8ES from Renesas Electronics is an 8-bit Flash-based microcontroller in the 78K0/KC1+ family, featuring 64 KB on-chip Flash memory, 4 KB RAM, a 16-bit timer/counter with PWM output, UART and I²C interfaces, and operation at up to 16 MHz. It integrates a 3–4 MHz internal RC oscillator, power-on reset (2.1 V ±0.1 V), and on-chip debug support - designed for embedded control in industrial sensors and motor-driven appliances.
For engineers reviewing the UPD78F0114HGB(A)-8ES datasheet, UPD78F0114HGB(A)-8ES pinout, UPD78F0114HGB(A)-8ES application, or UPD78F0114HGB(A)-8ES equivalent, key selection criteria include Flash self-programming capability, single-supply operation (2.7–5.5 V), internal oscillator configurability, and compatibility with RA78K0 assembler and CC78K0 C compiler toolchains.
Technical Context
This MCU implements the 78K0 CPU core with 16-bit address space, supports both external crystal (X1/X2) and internal RC oscillation modes, and includes a dedicated on-chip debug interface accessible via QB-78K0MINI emulator. Its interrupt system handles up to 32 sources with 4 priority levels, and its peripheral set includes a 10-bit ADC (8 channels), watchdog timer, and serial interface controller supporting UART/I²C protocols.
The device uses a single 2.7–5.5 V supply for both core and I/O, eliminating dual-rail design complexity. Flash memory supports block erase and byte programming with option byte configuration for oscillator stop control, POC threshold, and debug enable - enabling field firmware updates without external programming hardware.

FAQ
What is the maximum operating frequency of the UPD78F0114HGB(A)-8ES?
The UPD78F0114HGB(A)-8ES supports a maximum system clock frequency of 16 MHz when using an external crystal oscillator. With its internal RC oscillator, it operates at 3–4 MHz - configurable via option byte settings. The CPU executes instructions in a minimum of 0.125 µs per cycle at 16 MHz, enabling responsive real-time control in applications such as motor drive and sensor polling. This timing behavior is confirmed in the 78K0/KC1+ User's Manual (U16961EJ4V0UD).
Does the UPD78F0114HGB(A)-8ES support in-system programming?
Yes, the UPD78F0114HGB(A)-8ES supports full in-system programming (ISP) of its 64 KB on-chip Flash memory. It implements a self-programming function that allows firmware updates via UART or custom bootloader without removing the device from the target board. Block erase and byte-write capabilities are controlled through dedicated SFRs and protected by option byte configuration - a feature explicitly documented in the 78K0/KC1+ Flash Memory Self Programming User's Manual.
What debug tools are compatible with the UPD78F0114HGB(A)-8ES?
The UPD78F0114HGB(A)-8ES includes an on-chip debug interface compatible with the QB-78K0MINI On-Chip Debug Emulator (document U17029E). This enables real-time debugging, breakpoint insertion, register inspection, and memory read/write during active execution. Unlike earlier 78K0/KC1 devices, the UPD78F0114HGB(A)-8ES does not require external debug headers - the interface uses dedicated pins (e.g., CL1/CL2, RESET) shared with functional roles, as specified in Chapter 2 of U16961EJ4V0UD.
What is the power supply voltage range for the UPD78F0114HGB(A)-8ES?
The UPD78F0114HGB(A)-8ES operates from a single supply voltage ranging from 2.7 V to 5.5 V - covering standard 3.3 V and 5 V logic domains without level translation. This single-rail architecture simplifies power design and improves noise immunity between analog and digital sections. The device includes a dedicated power-on clear (POC) circuit triggering at 2.1 V ±0.1 V, ensuring reliable initialization even under brown-out conditions, as detailed in Section 1.4 of the 78K0/KC1+ User's Manual.
Is the UPD78F0114HGB(A)-8ES qualified for industrial temperature operation?
Yes, the UPD78F0114HGB(A)-8ES is rated for industrial temperature operation from −40°C to +85°C and classified under Renesas' "Standard" quality grade - approved for use in industrial robots, machine tools, and factory automation equipment. Its qualification aligns with the "Standard" category defined in Renesas documentation (e.g., Document No. C11531E), which explicitly lists industrial robots and machine tools among recommended applications. No additional customer qualification is required for these use cases.
