the CLIÉ handhelds.
This specification applies to the following CLIÉ models:
PEG-NX series
PEG-NR series
PEG-T series
PEG-SJ series
PEG-SL series
Before using this guide, please take notice on the following.

(no link to the power button of the
main unit)
<Models except PEG-SL10>
5.5~3.4V (*Note 1) Max. 100mA
Peripherals communicate with the main unit under a stable
power supply with setting UNREG_OUT to 3.2V LDO. Refer
to "Serial I/F Schematic Example".
<PEG-SL10>
3.1±0.2V Max. 80mA
The supply capability decreases when the battery is getting
exhausted.

Peripheral detection
Connect to the resistance between CNT
and the GND terminals as is shown in
Table 4 .
Do not supply any voltage to this pin from the peripheral side.
18 GND
Ground for signal/power supply
(*Note) 1. Desired value on design: 3.4 ~ 5.2V with the allowance ±0.3V. 3.4 ~ 4.2V if no AC adaptor is connected.
It can drop down to 3.1V when the battery gets exhausted. It remains below 3.4V at the
time the "low battery" warning shows up.
2. The actual number of physical pins on the CLIÉ connector is 20; the two most outside pins are unused.

At the side of peripherlas, set RXD to "Hi-Z" if
DTR=L. As it is connected to IrDA as well, main
unit may drive if DTR=L.. Peripherals are to be
driven by push/pull output.
As it is connected to IrDA as well, it may drive to H
even if DTR=L.
At the side of peripherlas, set CTS to "Hi-Z" if
DTR=L. Peripherals are to be driven by push/pull
output.
