PIC16F83/PIC16F84 pdf datashee

The PIC16F8X fits perfectly in applications ranging
from high speed automotive and appliance motor
control to low-power remote sensors, electronic locks,
security devices and smart cards. The Flash/EEPROM
technology makes customization of application
programs (transmitter codes, motor speeds, receiver
frequencies, security codes, etc.) extremely fast and
convenient. The small footprint packages make this
microcontroller series perfect for all applications with
space limitations. Low-cost, low-power, high
performance, ease-of-use and I/O flexibility make the
PIC16F8X very versatile even in areas where no
microcontroller use has been considered before
(e.g., timer functions; serial communication; capture,
compare and PWM functions; and co-processor
applications).
The serial in-system programming feature (via two
pins) offers flexibility of customizing the product after
complete assembly and testing. This feature can be
used to serialize a product, store calibration data, or
program the device with the current firmware before
shipping.
