Product details
Overview
UPD78F1014GC-UEU-AX from Renesas Electronics is a 16-bit single-chip microcontroller in the 78K0R/KG3-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 UPD78F1014GC-UEU-AX datasheet, UPD78F1014GC-UEU-AX pinout, UPD78F1014GC-UEU-AX application, or UPD78F1014GC-UEU-AX equivalent, key selection considerations include Flash endurance (100k write/erase cycles), dual voltage domains (EVDD/EVSS for analog section), and 64-pin LQFP package with dedicated ADC reference pins (AVREF/AVSS).
Technical Context
The UPD78F1014GC-UEU-AX implements the 78K0R CPU core with 16-bit architecture, supporting 119 instructions and 16 MB address space. It integrates a programmable 8-bit watchdog timer, power-on reset circuit, and low-voltage detection (LVD) with 4 selectable thresholds (2.7–4.2 V).
Its peripheral set includes three 16-bit timer arrays (each with capture/compare/PWM output), a 10-bit ADC with sample-and-hold and hardware trigger synchronization, and dual serial interfaces (UART channel 0 with LIN support and I²C-compatible interface with SMBus timeout detection).
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F100PLGSP | RL78/G13 core, 64 KB Flash, 4 KB RAM, same 64-pin LQFP but no LIN UART; lower max clock (32 MHz vs 20 MHz effective due to 1.25-cycle/MHz RL78 efficiency) | Lacks integrated LIN physical layer - requires external transceiver for automotive body networks. | Select when migrating to Renesas' newer RL78 platform with lower power consumption (<120 μA/MHz) and enhanced ESD immunity (±6 kV HBM). |
| MB95560P-GSXE1 | Fujitsu FM3 family, 128 KB Flash, 16 KB RAM, 64-pin LQFP, but uses ARM Cortex-M0+ core and lacks 78K0R instruction compatibility | Requires full firmware rewrite; offers higher floating-point throughput but no native 78K0R toolchain support. | Select only for greenfield designs prioritizing ARM ecosystem tools and future scalability over legacy code reuse. |
Compared with R5F100PLGSP and MB95560P-GSXE1, the UPD78F1014GC-UEU-AX provides drop-in replacement capability for existing 78K0R-based designs, retains full toolchain continuity (RA78K0R assembler, CC78K0R compiler), and delivers verified LIN compliance without external components - making it optimal for cost-sensitive industrial upgrades.

FAQ
What is the maximum operating frequency of the UPD78F1014GC-UEU-AX?
The UPD78F1014GC-UEU-AX operates at a maximum CPU clock frequency of 20 MHz using the on-chip high-speed oscillator or external crystal. This frequency is 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 time-critical control loops such as motor commutation and sensor sampling.
Does the UPD78F1014GC-UEU-AX support in-system programming (ISP)?
Yes, the UPD78F1014GC-UEU-AX supports in-application programming (IAP) via its on-chip Flash memory. Using the built-in boot ROM and UART0 interface, firmware updates can be performed without removing the device from the PCB. The UPD78F1014GC-UEU-AX requires no external programming voltage and maintains full functionality during IAP operations, including ADC sampling and timer interrupts.
What analog reference options are available for the ADC in the UPD78F1014GC-UEU-AX?
The UPD78F1014GC-UEU-AX ADC supports three reference configurations: external reference applied to AVREF pin (2.0–5.5 V), internal bandgap reference (2.5 V ±3%), or VDD as reference. Selection is controlled via the ADPC register. The internal reference is factory-trimmed and stable over temperature, eliminating need for external precision references in cost-sensitive industrial sensor applications.
Is the UPD78F1014GC-UEU-AX qualified for automotive applications?
The UPD78F1014GC-UEU-AX is rated for industrial temperature range (−40 °C to +85 °C) and carries Renesas' "Standard" quality grade per documentation. While it is used in automotive body electronics (e.g., LIN door modules), it is not certified to AEC-Q100 Grade 2 or higher. For safety-critical automotive applications, Renesas recommends the RL78/F1x or RH850 families instead of the UPD78F1014GC-UEU-AX.
How many independent PWM channels does the UPD78F1014GC-UEU-AX support?
The UPD78F1014GC-UEU-AX supports up to six independent PWM output channels through its three 16-bit timer array units (TAU). Each TAU channel can generate complementary PWM pairs with programmable dead-time insertion, enabling direct drive of 3-phase inverter bridges. All six channels are synchronized to a common trigger source, ensuring phase-aligned switching in motor control applications.
