Transcend Industrial CF Card  
(TS128M ~ 16GCF100I)  
Signal Name  
Dir.  
O
Pin  
Description  
-VS1  
-VS2  
33  
40  
Voltage Sense Signals. -VS1 is grounded on the Card and sensed by the Host  
so that the CompactFlash Storage Card CIS can be read at 3.3 volts and -VS2 is  
reserved by PCMCIA for a secondary voltage and is not connected on the Card.  
(PC Card Memory Mode)  
-VS1  
This signal is the same for all modes.  
-VS2  
(PC Card I/O Mode)  
-VS1  
This signal is the same for all modes.  
-VS2  
(True IDE Mode)  
-WAIT  
(PC Card Memory Mode)  
O
42  
The -WAIT signal is driven low by the CompactFlash Storage Card to signal the  
host to delay completion of a memory or I/O cycle that is in progress.  
-WAIT  
(PC Card I/O Mode)  
This signal is the same as the PC Card Memory Mode signal.  
In True IDE Mode, except in Ultra DMA modes, this output signal may be used  
as IORDY.  
IORDY  
(True IDE Mode – Except  
Ultra DMA Mode)  
In True IDE Mode, when Ultra DMA mode DMA Write is active, this signal is  
asserted by the host to indicate that the device is read to receive Ultra DMA  
data-in bursts. The device may negate -DDMARDY to pause an Ultra DMA  
transfer.  
-DDMARDY  
(True IDE Mode – Ultra DMA  
Write Mode)  
DSTROBE  
(True IDE Mode – Ultra  
DMA Read Mode)  
In True IDE Mode, when Ultra DMA mode DMA Write is active, this signal is the  
data out strobe generated by the device. Both the rising and falling edge of  
DSTROBE cause data to be latched by the host. The device may stop  
generating DSTROBE edges to pause an Ultra DMA data-out burst.  
-WE  
I
36  
This is a signal driven by the host and used for strobing memory write data to the  
registers of the CompactFlash Storage Card when the card is configured in the  
memory interface mode. It is also used for writing the configuration registers.  
(PC Card Memory Mode)  
-WE  
In PC Card I/O Mode, this signal is used for writing the configuration registers.  
(PC Card I/O Mode)  
-WE  
In True IDE Mode, this input signal is not used and should be connected to VCC  
by the host.  
(True IDE Mode)
