Overview
UPD78F1512AGC-GAD-AX from Renesas Electronics is a 16-bit single-chip microcontroller in the 78K0R/LF3 family, featuring 128 KB on-chip Flash memory, 8 KB RAM, and integrated 10-bit ADC with 24 channels. It operates at up to 20 MHz, supports I²C, UART, and CSI interfaces, and targets embedded control in industrial sensors and motor drives.
For engineers reviewing the UPD78F1512AGC-GAD-AX datasheet, UPD78F1512AGC-GAD-AX pinout, UPD78F1512AGC-GAD-AX application, or UPD78F1512AGC-GAD-AX equivalent, key selection criteria include Flash endurance (100k write/erase cycles), operating voltage range (2.7–5.5 V), and support for low-power STOP mode with RTC wake-up capability.
Technical Context
The UPD78F1512AGC-GAD-AX implements the 78K0R CPU core with 16-bit architecture, Harvard memory organization, and instruction set compatible with earlier 78K0 devices. It integrates a 32-bit programmable watchdog timer, 16-bit multifunction timer array (MTU), and dedicated hardware for PWM generation and encoder input capture.
Its peripheral set includes a 10-bit ADC with sample-and-hold and scan mode, dual serial interface units supporting synchronous/asynchronous communication, and on-chip voltage regulator (REGC) enabling single-supply operation. The device uses SuperFlash® technology licensed from SST for reliable Flash programming.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F10PLGAFP#V0 | Same 78K0R/LF3 family, identical pinout and peripheral set, but with 96 KB Flash and 6 KB RAM | Suitable for cost-sensitive designs where firmware size ≤96 KB and RAM usage ≤6 KB | Select when reduced memory suffices and lower unit cost is prioritized over future firmware headroom |
| UPD78F1510AGC-GAD-AX | Pin-compatible variant with 96 KB Flash, 6 KB RAM, and same peripheral complement except missing one UART channel | Appropriate for simpler serial communication requirements (single UART + I²C only) | Choose when application does not require dual UART functionality and memory footprint is constrained |
Compared with UPD78F1512AGC-GAD-AX, R5F10PLGAFP#V0 offers identical real-time control capability at lower memory density, while UPD78F1510AGC-GAD-AX removes one UART to reduce cost - both retain the same MTU, ADC, and low-power architecture critical for industrial timing and sensing.

FAQ
What is the maximum operating frequency of the UPD78F1512AGC-GAD-AX?
The UPD78F1512AGC-GAD-AX supports a maximum system clock frequency of 20 MHz, achievable either via its internal high-speed oscillator or an external crystal/resonator. At this speed, the 78K0R CPU delivers 1.15 DMIPS per MHz, enabling deterministic real-time response for motor control loops and sensor data processing within strict timing budgets.
Does the UPD78F1512AGC-GAD-AX include on-chip Flash memory with EEPROM emulation capability?
Yes, the UPD78F1512AGC-GAD-AX includes 128 KB of on-chip Flash memory built with SuperFlash® technology, which supports EEPROM emulation through dedicated firmware routines provided in Renesas' application notes. This allows nonvolatile storage of calibration data, device configuration, or event logs without external EEPROM components.
What power supply configurations does the UPD78F1512AGC-GAD-AX support?
The UPD78F1512AGC-GAD-AX operates from a single 2.7 V to 5.5 V supply and integrates an on-chip voltage regulator (REGC) that generates a stable 3.3 V core voltage. When REGC is enabled, only one external capacitor is required - eliminating the need for discrete LDOs and simplifying power design for space-constrained industrial modules.
Can the UPD78F1512AGC-GAD-AX perform simultaneous analog measurements on multiple channels?
Yes, the UPD78F1512AGC-GAD-AX features a 10-bit ADC with hardware scan mode supporting up to 24 input channels. It can execute sequential conversions without CPU intervention, storing results in dedicated RAM buffers - enabling synchronized sampling for three-phase voltage/current monitoring or multi-sensor environmental arrays.
Is the UPD78F1512AGC-GAD-AX qualified for industrial temperature range operation?
Yes, the UPD78F1512AGC-GAD-AX is rated for operation across the industrial temperature range of −40°C to +85°C and classified as a "Standard" quality grade device per Renesas documentation, making it suitable for deployment in factory automation equipment, building management systems, and outdoor metering terminals without derating.
