Product details
Overview
UPD78F0114M6GB-8ES-A 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, and a 16-bit timer/counter with PWM output capability. It operates at up to 20 MHz (50 ns min instruction cycle), supports 5V single-supply operation, and integrates UART, I²C, and 10-bit ADC for embedded control in industrial sensors and motor drive interfaces.
For engineers reviewing the UPD78F0114M6GB-8ES-A datasheet, UPD78F0114M6GB-8ES-A pinout, UPD78F0114M6GB-8ES-A application, or UPD78F0114M6GB-8ES-A equivalent, key selection criteria include Flash endurance (10,000 write/erase cycles), operating temperature range (−40°C to +85°C), and compatibility with RA78K0 assembler and CC78K0 C compiler toolchains.
Technical Context
The UPD78F0114M6GB-8ES-A implements the 78K0 CPU core with 16-bit ALU, 16-level hardware stack, and interrupt handling supporting 29 sources including external INT pins and peripheral-triggered events. Its memory architecture separates 64 KB program space (Flash) from 4 KB data RAM and includes dedicated SFR area for peripheral register access.
Peripheral integration includes a 10-bit, 16-channel ADC with conversion time of 1.2 µs, dual UARTs with LIN support, I²C master/slave mode, and three 16-bit timers - one with input capture/output compare and two with PWM generation - enabling precise timing control in closed-loop systems.

Pinout & Package
UPD78F0114M6GB-8ES-A is housed in a 64-pin LQFP package (10 mm × 10 mm, 0.5 mm pitch) with exposed thermal pad. Pin functions are defined per port group (P0–P7, P12, P13), each supporting configurable I/O, alternate peripheral functions, and internal pull-up resistors.
| Pin/Terminal | Circuit Role | Design Meaning |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 8-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F100PLAFB#50 | RL78/G13 core, 32 KB Flash, 4 KB RAM, lower power (120 µA/MHz), no on-chip LVD | Better suited for battery-powered devices; lacks integrated 5 V-tolerant I/O and high-speed PWM | Select when ultra-low power dominates over 5 V system compatibility and motor control precision |
| STM8S105K4T6C | STM8 core, 16 KB Flash, 2 KB RAM, 10-bit ADC (1.1 µs), single UART, no I²C | Lower cost but limited peripheral set; requires external level shifters for 5 V interfaces | Choose for cost-sensitive, low-complexity control where dual UART and I²C are unnecessary |
Compared with R5F100PLAFB#50 and STM8S105K4T6C, the UPD78F0114M6GB-8ES-A delivers higher Flash density, native 5 V I/O tolerance, and richer timer/PWM resources - making it optimal for industrial-grade 5 V systems requiring robust communication and analog integration without external support ICs.

FAQ
What is the maximum operating frequency of the UPD78F0114M6GB-8ES-A?
The UPD78F0114M6GB-8ES-A supports a maximum system clock frequency of 20 MHz, corresponding to a minimum instruction execution time of 50 ns. This timing is guaranteed under specified VDD (4.5 V to 5.5 V) and temperature (−40°C to +85°C) conditions, and applies when using either an external crystal (X1/X2) or the internal high-speed RC oscillator calibrated to 20 MHz.
Does the UPD78F0114M6GB-8ES-A support in-system programming?
Yes, the UPD78F0114M6GB-8ES-A supports in-system programming via its on-chip bootloader using the single-wire background debug (BDM) interface. No external VPP voltage is required, unlike mask ROM variants. Programming is performed through dedicated pins (e.g., P10 for BDI, P11 for BDO) using Renesas' PG-FP4 programmer or compatible tools such as ID78K0-QB.
What are the ADC performance specifications for the UPD78F0114M6GB-8ES-A?
The UPD78F0114M6GB-8ES-A features a 10-bit successive approximation ADC with 16 input channels, 1.2 µs conversion time, and ±2 LSB integral nonlinearity over the full −40°C to +85°C range. It includes an internal 2.5 V reference and supports simultaneous sampling on multiple channels via software-triggered or timer-triggered start.
Is the UPD78F0114M6GB-8ES-A pin-compatible with other 78K0/KC1 family members?
No, the UPD78F0114M6GB-8ES-A is not universally pin-compatible across the 78K0/KC1 family. While it shares the same 64-pin LQFP package with µPD78F0114(A) and µPD78F0114(A1), pin functions differ significantly from earlier mask ROM versions (e.g., µPD780114) due to added Flash-specific signals and reconfigured peripheral mappings - requiring PCB layout verification per Renesas' pin configuration diagrams.
What development tools are officially supported for the UPD78F0114M6GB-8ES-A?
Renesas officially supports the UPD78F0114M6GB-8ES-A with the RA78K0 Assembler Package (U11789E), CC78K0 C Compiler (U14298E), ID78K0-QB Ver. 2.81 Integrated Debugger (U16996E), and PG-FP4 Flash Memory Programmer (U15260E). These tools enable full firmware development, debugging, and field firmware updates without requiring third-party toolchain adaptation.
