memory. The onboard flash memory can endure a minimum of 1000
erase-write cycles. So you can reprogram and reuse the PIC chip at
least 1000 times. The program retention time, if you decide not to
rewrite the program, is approximately 40 years. The 18-pin 16F84
chip devotes 13 of its pins to I/O. Each pin may be independently
programmed as an input or output. The pin’s status (I/O direction
control) may also be changed on the fly via programming. Other
features include power on reset, power-saving sleep mode, power-
up timer, and code protection. Additional features and architecture
details of the PIC 16F84 will be given as we continue.
