By combining a versatile 8-bit CPU with Flash on a monolithic chip, the Atmel AT89C51 is a powerful microcomputer which provides a highly flexible and cost effective solution to many embedded control applications.
The AT89C51 provides the following standard features: Reset pin; Active high.
Read from external data memory. In addition, the AT89C51 is designed with static. Port P 0 and P 2 are also used to provide low byte and high byte addresses, respectively, when connected to an external memory.
These ports are also bit addressable and so their bits can also be accessed individually. There are no questions yet, be the first to ask something for this product.
