1.0

DEVICE OVERVIEW

This document contains device-specific information for

the following devices:

This family offers the advantages of all PIC18

microcontrollers

–

namely,

high

computational

performance at an economical price. In addition to

these features, the PIC18F6393/6493/8393/8493

family

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: This module incorporates

programmable acquisition time, allowing for a

channel to be selected and a conversion to be

initiated without waiting for a sampling period and

thus, reduces code overhead.

1.2

Details on Individual Family

Members

Devices in the PIC18F6393/6493/8393/8493 family are

available

64-pin

(PIC18F6X93)

and

80-pin

(PIC18F8X93) packages. Block diagrams for the two

groups are shown in Figure 1-1 and Figure 1-2,

respectively.

The devices are differentiated from each other in the

following ways:

• I/O Ports:

- 64-pin devices – 7 bidirectional ports

- 80-pin devices – 9 bidirectional ports

• LCD Pixels:

- 64-pin devices – 128 (32 SEGs x 4 COMs)

pixels can be driven

- 80-pin devices – 192 (48 SEGs x 4 COMs)

pixels can be driven

• Flash Program Memory:

- PIC18FX393 devices – 8 Kbytes

- PIC18FX493 devices – 16 Kbytes

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

PIC18F6393/6493/8393/8493 family are available as

both standard and low-voltage devices. Standard

devices with Flash memory, designated with an “F” in

the part number (such as PIC18F6393), accommodate

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

parts, designated by “LF” (such as PIC18LF6490),

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