The 80-LQFP package provides 65 general-purpose I/O lines, enough to interface with a keypad, a small character display, and a handful of sensors or actuators without external port expanders. ## Temperature range and supply tolerance for factory-floor reliability On-chip peripherals include DMA, LVD, POR, PWM, and WDT — the watchdog and brown-out reset alone reduce the need for external supervisor ICs in safety-conscious designs. ## Connectivity and analog integration The UPD78F1156AGC-GAD-AX integrates 3-wire SIO, I²C, LINbus, and UART/USART interfaces, covering the common serial protocols for sensor hubs, motor drive feedback, and LIN-node applications in automotive-adjacent designs. The 8-channel 10-bit ADC and dual 8-bit DAC allow direct connection to analog sensors and actuators — a thermistor front-end or a small-signal amplifier output can feed the ADC without an external converter.","metaTitle":"Renesas UPD78F1156AGC-GAD-AX 16-bit MCU, 256KB Flash","metaDescription":"Renesas 78K0R/Kx3 MCU, 16-bit core at 20 MHz, 256 KB flash, 12 KB RAM, -40 to 85°C.
