PIC18F65J94

8-Bit LCD Flash Microcontroller with USB and XLP Technology

Microchip Technology 

1.3 Other Special Features

• Communications: The PIC18F97J94 family

incorporates a range of serial communication

peripherals, including USB, four Enhanced

Addressable USARTs with IrDA, and two Master

Synchronous Serial Port MSSP modules capable

of both SPI and I2C™ (Master and Slave) modes

of operation.

• CCP Modules: PIC18F97J94 family devices

incorporate up to seven Capture/Compare/PWM

(CCP) modules. Up to six different time bases can

be used to perform several different operations at

once.

• ECCP Modules: The PIC18F97J94 family has

three Enhanced CCP (ECCP) modules to

maximize flexibility in control applications:

- Up to eight different time bases for

performing several different operations at

once

- Up to four PWM outputs for each module –

for a total of 12 PWMs

- Other beneficial features, such as polarity

selection, programmable dead time,

auto-shutdown and restart, and Half-Bridge

and Full-Bridge Output modes

• 12-Bit A/D Converter: The PIC18F97J94 family

has a software selectable, 10/12-bit

Analog-to-Digital (A/D) Converter. It 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, reducing code overhead.

• Charge Time Measurement Unit (CTMU): The

CTMU is a flexible analog module that provides

accurate differential time measurement between

pulse sources, as well as asynchronous pulse

generation.

• Together with other on-chip analog modules, the

CTMU can precisely measure time, measure

capacitance or relative changes in capacitance, or

generate output pulses that are independent of

the system clock.

• LP Watchdog Timer (WDT): This enhanced

version incorporates a 22-bit prescaler, allowing

an extended time-out range that is stable across

operating voltage and temperature. See

Section 31.0 “Electrical Characteristics” for

time-out periods.

• Real-Time Clock and Calendar Module

(RTCC): The RTCC module is intended for appli-

cations requiring that accurate time be maintained

for extended periods of time, with minimum to no

intervention from the CPU.

• The module is a 100-year clock and calendar with

automatic leap year detection. The range of the

clock is from 00:00:00 (midnight) on January 1,

2000 to 23:59:59 on December 31, 2099.

PIC18F97J94 FAMILY

1.4 Details on Individual Family

Members

Devices in the PIC18F97J94 family are available in

64-pin, 80-pin and 100-pin packages. Block diagrams

for the two groups are shown in Figure 1-1, Figure 1-2

and Figure 1-3.

The devices are differentiated from each other in these

ways:

• Flash Program Memory:

- PIC18FX5J94 – 32 Kbytes

- PIC18FX6J94 – 64 Kbytes

- PIC18FX6J99 – 96 Kbytes

- PIC18FX7J94 – 128 Kbytes

• Data RAM:

- All devices – 4 Kbytes

• I/O Ports:

- PIC18F6XJ9X (64-pin devices) – seven

bidirectional ports

- PIC18F8XJ9X (80-pin devices) – nine

bidirectional ports

- PIC18F9XJ9X (100-pin devices) – eleven

bidirectional ports

• A/D Channels:

- PIC18F6XJXX (64-pin devices) – 16 channels

- PIC18F8XJXX (80-pin devices) – 24 channels

- PIC18F9XJXX (100-pin devices) – 24 channels

All other features for devices in this family are identical.

These are summarized in Table 1-1, Table 1-2 and

Table 1-3.

The pinouts for all devices are listed in Table 1-4.
