This document contains device specific information for the PIC16F91X. Additional information may be found in the “PICmicro® Mid-Range MCU Family Reference Manual” (DS33023), 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 PIC16F91X devices are covered by this data sheet. It is available in 28/40/44-pin packages. Figure 1-1 shows a block diagram of the PIC16F913/ 916 device and Table 1-1 shows the pinout description. Figure 1-2 shows a block diagram of the PIC16F914/ 917 device and Table 1-1 shows the pinout description.
