• Manufacturer Part Number: TS256MDOM40V-S
• Description: Transcend 40-pin Ide Flash Module
• 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 is
