Product details
Overview
UPD78F0593GA-GAM-AX from Renesas Electronics is an 8-bit single-chip microcontroller in the 78K0/KC2-A family, featuring 64 KB on-chip Flash memory, 4 KB RAM, and a 16-bit timer/counter with capture/compare functionality. It operates at up to 20 MHz, supports 5 V operation, and integrates UART, I²C, and 10-bit ADC for embedded control in industrial sensors and motor drives.
For engineers reviewing the UPD78F0593GA-GAM-AX datasheet, UPD78F0593GA-GAM-AX pinout, UPD78F0593GA-GAM-AX application, or UPD78F0593GA-GAM-AX equivalent, this page delivers verified electrical specs, validated package mapping (LQFP-100), confirmed peripheral integration (ADC, UART, I²C), and real-world use context for rapid hardware/software co-design.
Technical Context
The UPD78F0593GA-GAM-AX implements the 78K0 CPU core with 16-bit address space and supports both internal high-speed oscillator (up to 20 MHz) and external crystal (X1/XT1) clock sources. Its clock generator includes programmable prescaler and subsystem clock division for flexible peripheral timing.
It features dual voltage domains: AVDD/AVSS for analog peripherals (10-bit ADC, AVREFP/AVREFM inputs) and VDD/VSS for digital logic. The device uses SuperFlash® technology for Flash endurance (>10,000 write/erase cycles) and includes on-chip debug support via QB-MINI2 interface.
