Description

Models 7P008IDE20, 7P016IDE20, 7P032IDE20, 7P040IDE20, 7P048IDE20 are Flash IDE drives. They are non-volatile mass memory storage systems, for mobile computing and industrial applications. Flashes drives fit into standard disk drive bays and use the industry standard IDE interface. They are light-weight, low profile devices.

System Features

-MS DOS compatible

-Low power

-Power down mode

-3V or 5V supply

-High reliability based on wear leveling system

-Automatic error detection and correction

-Block size 512 bytes

Drive Pin Explanation

Address bus (A0 to A2: input): In True IDE Mode only A [2 : 0] are used for selecting the one of eight registers in the Task File.

Data bus (D0 to D15: input/output): Data bus is D0 to D15. D0 is the LSB of the Even Byte of the Word. D8 is the LSB of the Odd Byte of the Word.

Card enable (-CE1, -CE2: input): In True IDE Mode -CE2 is used for select the Alternate Status Register and the Device Control Register while -CE1 is the chip select for the other task file registers.

I/O read (-IORD: input): -IORD is used for control of read data in the Task File area.

I/O write (-IOWR: input): -IOWR is used for control of data write in the Task File area.

Interrupt request (IRQ: output): In True IDE Mode the signal is the active high Interrupt Request to the host.

-IOIS16: (output) In True IDE Mode this output signal is asserted low when this device is expecting a word data transfer cycle.

Disk active/slave present (-DASP: input/output): In True IDE Mode -DASP is the Disk Active/Slave Present signal in the Master/Slave handshake protocol.

Reset (-RESET: input): By assertion of the RESET signal, all registers of this card are cleared and the RDY/-BSY signal turns to high level. In True IDE Mode -RESET is the active low hardware reset from the host.

Wait (-WAIT, IORDY: output):. In True IDE Mode this output signal may be used as IORDY. As for this controller, this output is high impedance state constantly.

Pass diagnostic (-PDIAG: input/output):. In True IDE Mode, -PDIAG is the Pass Diagnostic signal in the Master/Slave handshake protocol.

Card select (-CSEL: input): This internally pulled up signal is used to configure this device as a Master or a Slave when configured in the True IDE Mode. When this pin is grounded, this device is configured as a Master. When the pin is open, this device is configured as a Slave.

Master/Slave configuration: If the flash drive is being installed as a second drive (or Slave), pin 48 or pin 49 must be grounded. Pins 48 and 49 are inputs with pull up resistors and they are shorted internally. If both pins are open, the flash drive is configured as the Master drive or as the only one drive in the system. NOTE: Detailed description of flash drive functionality, including timing can be found in the technical specification for PCMCIA card: ATA20 series.
