3.3.2
J2 (J3): PCMCIA
Integrated Ejector: FCI 95620-050CA
The 68-pin PCMCIA socket conforms to the PCMCIA standard for 5V-tolerant Type II cards, and
can also be run at 3.3 V. Normally, the socket is de-energized. The operating system is
responsible for turning on the socket when a card is inserted and turning it off when the card is
removed. Ejector hardware is standard. Vpp (pins 18 and 52), which is 12 V in older PCMCIA
implementations, is left unconnected in this implementation.
3.3.3
J3 (J9): Power, I/O, Serial 2 & 3, USB, Touch Screen and others
Board Connector: 2x25 shrouded header, 2 mm, Samtec STMM-125-02-G-D
Recommended Board-to-Cable Connector: TCSD series
Recommended Board-to-Board Connector: ESQT series (e.g. ESQT-125-02-F-D-500)

The LCD panel scan direction is selected by changing the voltage on the PNL_RL and PNL_UD
signals. These signals are pulled up on standard Bitsy G5 boards.
