• Manufacturer Part Number: TS1GDOM44H-S
• Description: 44-Pin IDE Flash Modules
• Manufacturer: Transcend Information, Inc.

Notes:
(1) Device address consists of -CS0, -CS1, and A[02::00]
(2) Data consists of D[15::00] (16-bit) or D[07::00] (8 bit)
(3) -IOCS16 is shown for PIO modes 0, 1 and 2. For other modes, this signal is ignored.
(4) The negation of IORDY by the device is used to extend the PIO cycle. The determination of whether the cycle
