PIC16F84-04P

The PIC16F84-04P is one member of the PIC16F8X series.It has the following features including (1)In-Circuit Serial Programming (ICSP™) - via two pins (ROM devices support only Data EEPROM programming);(2)Watchdog Timer (WDT) with its own on-chip RC oscillator for reliable operation;(3)Oscillator Start-up Timer (OST);(4)Power saving SLEEP mode;(5)Selectable oscillator options;(6)Power-up Timer (PWRT).

The PIC16F84-04P 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 PIC16F84-04P with the current firmware before shipping.

The devices PIC16F84-04P with Flash program memory allow the same device package to be used for prototyping and production. In-circuit reprogrammability allows the code to be updated without the device being removed from the end application. This is useful in the development of many applications where the device may not be easily accessible, but the prototypes may require code updates. This is also useful for remote applications where the code may need to be updated (such as rate information).These devices are offered in the lower cost plastic package, even though the device can be erased and reprogrammed. This allows the same device PIC16F84-04P to be used for prototype development and pilot programs as well as production.
