AT89C51-12PC Product Details

AT89C51-12PC Overview


The microprocessor is convenient for international shipping since it is packaged in PDIP. uPs/uCs/Peripheral ICs are a MICROCONTROLLER. To date, there have been 40 terminations. You should be able to turn on and run the embedded microprocessor with a voltage supply of 5V. An architecture based on 8 bits is used. The embedded microprocessor is a typical Microcontrollers. To transfer data, there is a bandwidth of 8b. If the temperature is higher than 70°C, the microprocessor should not operate. A total of 40 pins are injected into the CPU microprocessor's body. It is expected that the CPU will reach a top frequency of 12MHz. It is possible to use the micro processor from 5V. It is designed with 0 RAM (Random-Access Memory). A voltage greater than 6V should not normally be applied to the embedded microprocessor. It is recommended to feed the CPU microprocessor with a voltage of 4V. By using 32 I/Os, CPU programs transfer data. Memory size on the CPU is 4kB. CPU activity is measured by the 2 counters. This CPU microprocessor has 32 programmable I/Os for I/O transfer.
