DEVICE OVERVIEW
This document contains device-specific information for
the operation of the PIC16F84A device. Additional
information may be found in the PICmicro Mid-Range
Reference Manual, (DS33023), which may be down-
loaded from the Microchip website. The Reference
Manual should be considered a complementary docu-
ment to this data sheet, and is highly recommended
reading for a better understanding of the device archi-
tecture and operation of the peripheral modules.
The PIC16F84A belongs to the mid-range family of the
PICmicro microcontroller devices. A block diagram of
the device is shown in Figure 1-1.
The program memory contains 1K words, which trans-
lates to 1024 instructions, since each 14-bit program
memory word is the same width as each device instruc-
tion. The data memory (RAM) contains 68 bytes. Data
EEPROM is 64 bytes.
There are also 13 I/O pins that are user-configured on
a pin-to-pin basis. Some pins are multiplexed with other
device functions. These functions include:
External interrupt
Change on PORTB interrupt
Timer0 clock input
Table 1-1 details the pinout of the device with descrip-
tions and details for each pin.
