In addition, the AT89C51 is designed with static.
Three-Level Program Memory Lock 5. I have read and agree to the website terms and conditions.
Low-order address bits when interfacing with external memory. All these ports are 8-bit bi-directional ports, i.
Except P 0 which needs external pull-ups, rest of the ports have internal pull-ups. Read more in our Privacy Policy. It can be programmed to operate at different baud rates. It is not stored on this sites database. Programmable Serial Channel The product is already in the wishlist! Quartz crystal oscillator up to 24 MHz.
The on-chip Flash allows the program memory to be reprogrammed in-system or by a conventional nonvolatile memory programmer. Read from external data memory. It can be erased and program to a maximum of times. This high-density System-in-Package SiP integrates controller, power switches, and support components. Compatible with MCS Products 2. 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. Programming enable voltage; 12V during Flash programming.
Input receiver for serial communication. SPI Module of Arduino. Program pulse input during Flash programming. Write to external data memory.
