2.4.7
The ADS comes equipped with a PCMCIA card holder, U59. Most of the PCMCIA interface signals are
buffered including the data and address that are shared with other system peripherals. The card is powered
by a LTC1472CS power switch. Only 3.3V cards are supported. The CPLD controls the LTC1472CS. It
can turn VCC power ON and OFF and VPP power can be set to +5V or left unconnected (Hi-Z). These
default to OFF and unconnected at reset. You must supply a compatible PCMCIA card for use with the
i.MX27 ADS.
2.4.8
The ADS provides an ATA compatible interface designed to work with 1.8 inch mini hard drives. P13 is a
44 pin header designed to be compatible with ATA/ATAPI-6 standard. The mini hard drive installs into the
dual row, 2mm spaced connector which is on the bottom side of the ADS. Ribbon cable is not required.
Most of the ATA signals are multiplexed and then translated to 3.3V levels for the mini hard drive. The
CPLD controls the multiplexer enables and selects.
2.4.9
The ADS provides an ETM connector (P23) for connecting the ARM based i.MX27 CPU to an ARM
supplied ETM (Embedded Trace Macrocell). Since this capability is normally needed only during
development, the ETM functions are pin shared with other modules. Using these pins for ETM will
prohibit their use with the other modules. The modules include ATA and NAND flash.
2.4.10
The ADS has two specialized Samtec connectors (P8 and P9) designed to be compatible with Logic
Analyzer cables from HP that use the mating connector. All CPU connections required for memory
interfacing are brought to these connectors.

Make sure that input power is disconnected or switched off before the mini
hard drive is connected. Connecting it with power applied can damage the
mini hard drive and the ADS board.
