This family introduces a new line of low-voltage LCD

microcontrollers with Universal Serial Bus (USB). It

combines all the main traditional advantage of all

PIC18 microcontrollers, namely, high computational

performance and a rich feature set at an extremely

competitive price point. These features make the

PIC18F97J94 family a logical choice for many

high-performance applications, where cost is a primary

consideration.

1.1 Core Features

1.1.1 TECHNOLOGY

All of the devices in the PIC18F97J94 family incorporate

a range of features that can significantly reduce power

consumption during operation. Key items include:

• Alternate Run Modes: By clocking the controller

from the Timer1 source or the Internal RC oscilla-

tor, power consumption during code execution

can be reduced.

• Multiple Idle Modes: The controller can also run

with its CPU core disabled but the peripherals still

active. In these states, power consumption can be

reduced even further.

• On-the-Fly Mode Switching: The power-managed

modes are invoked by user code during operation,

allowing the user to incorporate power-saving ideas

into their application’s software design.

• XLP: An extra low-power Sleep, BOR, RTCC and

Watchdog Timer.

1.1.2

OSCILLATOR OPTIONS AND

FEATURES

All of the devices in the PIC18F97J94 family offer differ-

ent oscillator options, allowing users a range of choices

in developing application hardware. These include:

• Two Crystal modes (HS, MS)

• One External Clock mode (EC)

• A Phase Lock Loop (PLL) frequency multiplier,

which allows clock speeds of up to 64 MHz.

• A fast Internal Oscillator (FRC) block that provides

an 8 MHz clock (±0.15% accuracy) with Active

Clock Tuning (ACT) from USB or SOSC source.

- Offers multiple divider options from 8 MHz to

500 kHz

- Frees the two oscillator pins for use as

additional general purpose I/O

• A separate Low-Power Internal RC Oscillator

(LPRC) (31 kHz nominal) for low-power,

timing-insensitive applications.

The internal oscillator block provides a stable reference

source that gives the family additional features for

robust operation:

• Fail-Safe Clock Monitor (FSCM): This option

constantly monitors the main clock source against a

reference signal provided by the internal oscillator.

If a clock failure occurs, the controller is switched to

the internal oscillator, allowing for continued

low-speed operation or a safe application

shutdown.

• Two-Speed Start-up (IESO): This option allows

the internal oscillator to serve as the clock source

from Power-on Reset, or wake-up from Sleep

mode, until the primary clock source is available.
