Intel N80C51RA-20 is an 8-bit microcontroller featuring the robust 8051 CPU family. This CMOS device operates at a maximum clock frequency of 20MHz, offering a 512-byte on-chip data RAM and supporting 16-bit addressing. It provides 32 general-purpose I/O lines, one serial I/O port, and three timers. The N80C51RA-20 supports on-circuit emulation and includes low-power modes. This component is housed in a 44-terminal PQCC package (JESD-30 Code S-PQCC-J44) with a 1.27mm terminal pitch. It is designed for applications requiring a high-performance 8-bit architecture, commonly found in industrial automation, consumer electronics, and embedded control systems. The operating temperature range is 0°C to 70°C, with a supply voltage range of 4.0V to 6.0V.
