PIC18F8723 FAMILY

1.0

DEVICE OVERVIEW

This document contains device-specific information for

the following devices:

The PIC18F8723 family of devices offers the

advantages of all PIC18 microcontrollers – namely, high

computational performance at an economical price –

with the addition of high-endurance, Enhanced Flash

program memory. In addition to these features, the

PIC18F8723 introduces design enhancements that

make these microcontrollers a logical choice for many

high-performance, power-sensitive applications.

1.1

Special Features

• 12-Bit A/D Converter: The PIC18F8723 family

implements a 12-bit A/D Converter. A/D Converters

in both families incorporate programmable acquisi-

tion time. This allows for a channel to be selected

and a conversion to be initiated, without waiting for

a sampling period and thus, reducing code

overhead.

1.2

Details on Individual Family

Members

Devices in the PIC18F8723 family are available in

64-pin and 80-pin packages. Block diagrams for the

two groups are shown in Figure 1-1 and Figure 1-2.

The devices are differentiated from each other in the

following ways:

• Flash program memory (96 Kbytes for

PIC18FX628 devices and 128 Kbytes for

PIC18FX723).

• A/D channels (12 for PIC18F6628/6723 devices

and 16 for PIC18F8628/8723 devices).

• I/O ports (seven bidirectional ports on

PIC18F6628/6723 devices and nine bidirectional

ports on PIC18F8628/8723 devices).

• External Memory Bus, configurable for 8 and

16-bit operation

All other features for devices in this family are identical.

These are summarized in Table 1-1.

The pinouts for all devices are listed in Table 1-2 and

Table 1-3.

Like all Microchip PIC18 devices, members of the

PIC18F8723 family are available as both standard and

low-voltage devices. Standard devices with Enhanced

Flash memory, designated with an “F” in the part

number (such as PIC18F6628), accommodate an

operating VDD range of 4.2V to 5.5V. Low-voltage

parts, designated by “LF” (such as PIC18LF6628),

function over an extended VDD range of 2.0V to 5.5V.

the PIC18F8723 family and PIC18F8722 fam-

ily devices, see the “PIC18F8722 Family Data

Sheet” (DS39646).
