This document contains device specific information for the 12F629, PIC12F629/675. Additional information may be found in the PICmicroTM Mid-Range Reference Manual (DS33023), which may be obtained from your local Microchip Sales Representative or downloaded from the Microchip web site. The Reference Manual should be considered a complementary document to this Data Sheet, and is highly recommended reading for a better understanding of the device architecture and operation of the peripheral modules.
The PIC12F629 and PIC12F675 devices are covered by this Data Sheet. They are identical, except the PIC12F675 has a 10-bit A/D converter. They come in 8-pin PDIP, SOIC, and MLF-S packages. Figure 1-1 shows a block diagram of the PIC12F629/675 devices. Table 1-1 shows the Pinout Description.
