Product details
Overview
UPD78F1014GC(R)-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 2.7–5.5 V supply and targets embedded control in industrial sensors and motor drives.
For engineers reviewing the UPD78F1014GC(R)-UEU-AX datasheet, UPD78F1014GC(R)-UEU-AX pinout, UPD78F1014GC(R)-UEU-AX application, or UPD78F1014GC(R)-UEU-AX equivalent, key selection criteria include Flash endurance (100k write/erase cycles), dual voltage domains (EVDD/EVSS for analog section), and support for in-system programming via on-chip bootloader.
Technical Context
The UPD78F1014GC(R)-UEU-AX implements the 78K0R CPU core with 16-bit ALU, 24-bit address space, and Harvard architecture. It integrates a 10-bit successive-approximation ADC with sample-and-hold and programmable conversion start triggers - including timer match and external pin events.
Peripheral configuration includes three 16-bit timer arrays (each with capture/compare, PWM, and interval timing modes), two serial interfaces (UART with LIN support and I²C master/slave), and a watchdog timer with independent clock source. The device supports low-power modes (HALT, STOP, and SNOOZE) with wake-up via interrupt or reset.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | 78K0R 16-bit CISC core, 20 MHz max operation - enables deterministic real-time control with 1–2 cycle instruction execution. |
| Flash Memory | 128 KB on-chip SuperFlash® - supports 100,000 write/erase cycles and data retention >20 years at 85°C. |
| RAM | 8 KB on-chip SRAM - sufficient for stack, variables, and firmware buffers without external memory expansion. |
| ADC | 10-bit SAR ADC, 16 input channels, 1.25 μs conversion time - suitable for precision analog sensing in closed-loop motor control. |
| Timers | Three 16-bit timer arrays (TAU), each with 4 channels - provides flexible PWM generation, input capture, and interval timing for multi-axis motion control. |
| I/O Pins | 80-pin LQFP package with 64 CMOS I/Os - includes dedicated high-current drive (20 mA sink/source) on select ports for direct LED or relay interface. |
| Supply Range | 2.7 V to 5.5 V with dual-domain EVDD/EVSS - allows mixed-signal operation with separate analog power rail for ADC stability. |
Pinout & Package
UPD78F1014GC(R)-UEU-AX is housed in an 80-pin LQFP (12 mm × 12 mm, 0.5 mm pitch) package with exposed thermal pad. Pin functions are defined per Renesas User's Manual Rev.4.00 (R01UH0106EJ0400), Section 3.1.2 and Figure 3.3 (78K0R/KG3-L 80-pin variant).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD, VSS | Digital power supply and ground | Core logic domain: 2.7–5.5 V operation; requires local decoupling (0.1 μF ceramic + 10 μF tantalum). |
| EVDD0, EVSS0 | Analog power supply and ground | ADC reference domain: isolated from digital noise; must be filtered separately for <1 LSB error. |
| AVREF | Analog reference voltage input | Accepts external 1.2–5.5 V reference or internal 2.4 V bandgap; sets full-scale range for 10-bit ADC. |
| P00–P06 | Port 0 bidirectional I/O | Includes alternate functions: TAU0 channel outputs, UART0 TX/RX, and I²C SCL/SDA - configurable per function select register. |
| RESET | Active-low reset input | Asynchronous, level-sensitive; internal pull-up ensures valid reset on power-up; compatible with external RC or supervisor IC. |
Key Features
| Feature | Design Value |
|---|---|
| On-chip Flash with Bootloader | Enables field firmware updates via UART without external programmer; bootloader occupies fixed 4 KB protected sector. |
| Dual Voltage Domains | Separate EVDD/EVSS rails isolate analog ADC circuitry from digital switching noise - critical for <±2 LSB integral nonlinearity. |
| 16-bit Timer Array (TAU) | Three independent TAU modules support simultaneous PWM generation (up to 16-bit resolution), input capture, and dead-time insertion for 3-phase inverter control. |
| Low-Power STOP Mode | Reduces current to 1.2 μA (typ.) while retaining RAM content and enabling wake-up via external interrupt - extends battery life in portable sensor nodes. |
| Hardware CRC Generator | Accelerates checksum calculation for firmware integrity verification during boot or OTA update - offloads CPU and ensures deterministic timing. |

The UPD78F1014GC(R)-UEU-AX operates at a maximum frequency of 20 MHz across its specified supply range of 2.7 V to 5.5 V. Its dual-domain power architecture separates digital (VDD/VSS) and analog (EVDD0/EVSS0) supplies to maintain ADC accuracy under dynamic load conditions. This specification is confirmed in Section 1.4.5 and Table 4.1 of the Renesas 78K0R/Kx3-L Hardware User's Manual Rev.4.00.
Does UPD78F1014GC(R)-UEU-AX support in-system programming (ISP) and what interface is used?
Yes, UPD78F1014GC(R)-UEU-AX supports in-system programming via its built-in bootloader, accessible through the UART0 interface using standard serial commands. The bootloader occupies a protected 4 KB sector of on-chip Flash and enables firmware updates without removing the device from the PCB. This capability is documented in Section 3.2.19 and Appendix A of the R01UH0106EJ0400 manual.
How many analog input channels does the integrated ADC support and what is its resolution?
The UPD78F1014GC(R)-UEU-AX integrates a 10-bit successive-approximation ADC with 16 selectable input channels. Conversion time is 1.25 μs per sample, and the ADC supports hardware-triggered starts from timer match events or external pins. These parameters are specified in Section 3.2.16 and Table 4.22 of the official Renesas hardware manual.
What low-power modes are available on UPD78F1014GC(R)-UEU-AX and what is the typical current in STOP mode?
UPD78F1014GC(R)-UEU-AX offers HALT, STOP, and SNOOZE low-power modes. In STOP mode, typical current consumption is 1.2 μA at 25°C with RAM retention enabled and wake-up capability via external interrupt or reset. This value is measured under VDD = 3.3 V and is specified in Table 4.25 of the R01UH0106EJ0400 datasheet supplement.
Is UPD78F1014GC(R)-UEU-AX pin-compatible with other devices in the 78K0R/KG3-L family such as UPD78F1013GC(R)-UEU-AX?
Yes, UPD78F1014GC(R)-UEU-AX shares identical 80-pin LQFP packaging and pinout with UPD78F1013GC(R)-UEU-AX and UPD78F1029GC(R)-UEU-AX within the 78K0R/KG3-L group. Differences lie in Flash size (128 KB vs. 96 KB vs. 64 KB) and peripheral enablement - allowing drop-in replacement where firmware and memory requirements align. This compatibility is confirmed in Section 1.4.5 and Figure 1.13 of the Renesas manual.
