Renesas UPD78F1510AGC-GAD-AX

Overview

UPD78F1510AGC-GAD-AX from Renesas Electronics is a 16-bit single-chip microcontroller in the 78K0R/Lx3 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 drive subsystems.

For engineers reviewing the UPD78F1510AGC-GAD-AX datasheet, UPD78F1510AGC-GAD-AX pinout, UPD78F1510AGC-GAD-AX application, or UPD78F1510AGC-GAD-AX equivalent, key selection considerations include its 100-pin LQFP package, 2.7–5.5 V supply range, built-in voltage regulator (REGC), and support for low-power STOP mode with RTC wake-up capability.

Technical Context

The UPD78F1510AGC-GAD-AX implements the 78K0R CPU core with 16-bit architecture, Harvard memory organization, and instruction set compatible with earlier 78K0 series. It integrates a programmable 8-bit watchdog timer, 16-bit multifunction timer array (TAA), and dedicated PWM output channels for motor control.

Its analog subsystem includes a 10-bit ADC with sample-and-hold, selectable reference sources (AVREF/AVDD), and hardware-triggered conversion sequencing. The device uses a single 2.7–5.5 V supply with internal voltage regulation via REGC pin, eliminating need for external LDO in many applications.

FAQ

What is the maximum operating frequency of the UPD78F1510AGC-GAD-AX?

The UPD78F1510AGC-GAD-AX operates at a maximum CPU clock frequency of 20 MHz using its on-chip high-speed oscillator or external crystal. This frequency is fully supported across the full −40 °C to +85 °C industrial temperature range and 2.7–5.5 V supply voltage, with timing margins verified per Renesas Hardware User's Manual Rev.5.01.

Does the UPD78F1510AGC-GAD-AX support in-circuit debugging?

Yes, the UPD78F1510AGC-GAD-AX supports on-chip debugging via the QB-MINI2 emulator and ID78K0R-QB integrated debugger. It implements the standard 78K0R debug interface with SWD-like serial wire protocol, allowing full breakpoint, watchpoint, and register inspection capabilities without requiring dedicated debug pins beyond RESET and CLK.

What is the purpose of the REGC pin on the UPD78F1510AGC-GAD-AX?

The REGC pin on the UPD78F1510AGC-GAD-AX controls the internal voltage regulator that generates the 3.3 V EVDD supply from the main VDD rail. When driven high, it enables the regulator; an external 1 μF ceramic capacitor must be connected between EVDD and EVSS to ensure stable operation and noise suppression for analog and digital peripherals.

Can the UPD78F1510AGC-GAD-AX drive an LCD display directly?

Yes, the UPD78F1510AGC-GAD-AX includes a built-in LCD controller with four voltage-level outputs (VLC0–VLC3) supporting static or multiplexed (up to 4-common) segment LCDs. This eliminates the need for external LCD driver ICs in applications such as smart meters and industrial HMI panels.

Is the UPD78F1510AGC-GAD-AX pin-compatible with other devices in the 78K0R/Lx3 family?

The UPD78F1510AGC-GAD-AX is pin-compatible with other 100-pin LQFP variants in the 78K0R/LF3 subgroup (e.g., UPD78F1500A, UPD78F1501A), sharing identical pin functions for power, reset, clocks, and primary I/O ports. Peripheral-specific pins (e.g., VLC, COM) are consistent across LF3 members, enabling shared PCB layouts.
