DS30325B-page 5 PIC16F7X 1.0 DEVICE OVERVIEW This document contains device specific information about the following devices: • PIC16F73 • PIC16F74 • PIC16F76 • PIC16F77 PIC16F73/76 devices are available only in 28-pin pack- ages, while PIC16F74/77 devices are available in 40-pin and 44-pin packages. All devices in the PIC16F7X family share common architecture, with the following differences: • The PIC16F73 and PIC16F76 have one-half of the total on-chip memory of the PIC16F74 and PIC16F77 • The 28-pin devices have 3 I/O ports, while the 40/44-pin devices have 5 • The 28-pin devices have 11 interrupts, while the 40/44-pin devices have 12 • The 28-pin devices have 5 A/D input channels, while the 40/44-pin devices have 8 • The Parallel Slave Port is implemented only on the 40/44-pin devices The available features are summarized in Table 1-1. Block diagrams of the PIC16F73/76 and PIC16F74/77 devices are provided in Figure 1-1 and Figure 1-2, respectively. The pinouts for these device families are listed in Table 1-2 and Table 1-3. Additional information may be found in the PICmicro™ Mid-Range Reference Manual (DS33023), which may be obtained from your local Microchip Sales Represen- tative or downloaded from the Microchip website. The Reference Manual should be considered a complemen- tary document to this data sheet, and is highly recom- mended reading for a better understanding of the device architecture and operation of the peripheral modules.
