AT89C51-12PC Overview
The embedded microprocessor has been packed in PDIP for convenient overseas shipping. In terms of uPs and uCs as well as peripheral ICs, this is a MICROCONTROLLER. A total of 40 terminations have been recorded. Using a 5V voltage supply, the microprocessor should turn on and run. 8-Bit is its architecture. This microprocessor is a typical Microcontrollers. The size of data Bus of the CPU is based on 8b-bit system. Temperatures above 70°C are not suitable for operating the microprocessor. Embedded microprocessor bodies are injected with 40 pins. CPU frequency should reach 12MHz. In this case, 5V is the starting point. There is 128B RAM (Random Access Memory) built in. Microprocessors should never be supplied with voltages above 6V in normalcircumstances. A voltage of 4V is recommended for feeding the embedded microprocessor. In CPU programs, data is transferred by 32 I/Os. There is 4kB memory on the CPU. 2 counters are used to help tell how busy the CPU is. This embedded microprocessor has 32 programmable I/Os for data transfer.
