Product details
Overview
UPD78F1176AGF-GAT-AX from Renesas Electronics is a 16-bit single-chip microcontroller in the 78K0R/KE3 family, featuring 128 KB Flash memory, 8 KB RAM, and integrated peripherals including 16-bit timer arrays, UART, I²C, and 10-bit ADC. It operates at up to 20 MHz with supply voltage range 2.7–5.5 V and targets embedded control in industrial HMI and motor drive subsystems.
For engineers reviewing the UPD78F1176AGF-GAT-AX datasheet, UPD78F1176AGF-GAT-AX pinout, UPD78F1176AGF-GAT-AX application, or UPD78F1176AGF-GAT-AX equivalent, key selection criteria include Flash endurance (100k write/erase cycles), operating temperature range (−40°C to +85°C), on-chip debug support via single-wire interface, and compliance with industrial-grade reliability standards.
Technical Context
The UPD78F1176AGF-GAT-AX implements the 78K0R CPU core with 16-bit ALU, 24-bit address space, and Harvard architecture supporting simultaneous instruction fetch and data access. It integrates a programmable low-voltage detector (LVD) with 4 selectable thresholds and a 32-bit watchdog timer with independent clock source.
Peripheral integration includes two 16-bit timer arrays (each with 4 channels), three serial interfaces (UART ×2, I²C ×1), and a 10-bit ADC with 16 input channels and hardware-triggered conversion sequencing - all accessible via dedicated SFRs and interrupt vectors mapped to fixed priority levels.
