Description

A/D converted data is sent to the host CPU.

Normalized data is sent to the host CPU.

Asynchronous serial communications

External switches are used to set the initial communication rate. See the “External

Switch Settings” charts. However, the LC19001A010 does not support 19200-bps

communication at 8 MHz. The rate can be changed by command.

External switches are used to set the initial communication format. See the

“External Switch Settings” charts.

10 MHz: Maximum normalized data rate: 150 p/s

Maximum source data rate: 190 p/s

(When the baud rate is 19200)

8 MHz: Maximum normalized data rate: 120 p/s

Maximum source data rate: 150 p/s

(When the baud rate is 9600)

Note: The above values apply when no menu area is registered.

See the “Coordinate Data Format” charts.

When the pen is down, coordinate values are output one point at a time.

While the pen remains down, coordinate values are output continuously.

140 mW (MAX) At a 10-MHz operating frequency, with the pen down

Sleep: CPU operation is stopped, but all other circuits operate.

Stop: The oscillator circuit is stopped.

Methods for switching modes:

Direct

Auto

There are two types of command that are used to switch to the low power modes

as follows:

Direct: The LC19001A010 switches to the low power mode after the command is

accepted.

Auto: After the last coordinate input, if there is no input for a preset time, the

LC19001A010 switches to the low power mode.

Transition times

• Transition from normal mode to low power mode: about 5 µs

• Transition from low power mode to normal mode:

Sleep mode: about 5 µs

Stop mode: The oscillator stabilization period plus 5 µs

3.3 to 6 V

An 8 MHz clock frequency must be used when the drive voltage is 3.3 V.
