Notes: 1) Control Signals: each card shall present a load to the socket no larger than 50 pF 10 at a DC current of 700

μ A

low state and 150

μ A high state, including pull-resistor. The socket shall be able to drive at least the following

load 10 while meeting all AC timing requirements: (the number of sockets wired in parallel) multiplied by (50 pF

with DC current 700

μ A low state and 150 μ A high state per socket).

2) Resistor is optional.

3) Status Signals: the socket shall present a load to the card no larger than 50 pF 10 at a DC current of 400

μ A low

state and 100

μ A high state, including pull-up resistor. The card shall be able to drive at least the following load

while meeting all AC timing requirements: 50 pF at a DC current of 400

μ A low state and 100 μ A high state.

4) Status Signals: the socket shall present a load to the card no larger than 50 pF 10 at a DC current of 400

μ A low

state and 100

μ A high state, including pull-up resistor. The card shall be able to drive at least the following load

while meeting all AC timing requirements: 50 pF at a DC current of 400

μ A low state and 100 μ A high state.

5) Status Signals: the socket shall present a load to the card no larger than 50 pF 10 at a DC current of 400

μ A low

state and 100

μ A high state, including pull-up resistor. The card shall be able to drive at least the following load

while meeting all AC timing requirements: 50 pF at a DC current of 400

μ A low state and 1100 μ A high state.

6) BVD2 was not defined in the JEIDA 3.0 release. Systems fully supporting JEIDA release 3 SRAM cards shall

pull-up pin 45 (BVD2) to avoid sensing their batteries as “Low.”

7) Address Signals: each card shall present a load of no more than 100pF 10 at a DC current of 450

μ A low state and

150

μ A high state. The host shall be able to drive at least the following load 10 while meeting all AC timing

requirements: (the number of sockets wired in parallel) multiplied by (100pF with DC current 450

μ A low state

and 150

μ A high state per socket).

8) Data Signals: the host and each card shall present a load no larger than 50pF 10 at a DC current of 450

μ A and

150

μ A high state. The host and each card shall be able to drive at least the following load 10 while meeting all

AC timing requirements: 100pF with DC current 1.6mA low state and 300

μ A high state. This permits the host to

wire two sockets in parallel without derating the card access speeds.

9) Reset Signal: This signal is pulled up to prevent the input from floating when a CFA to PCMCIA adapter is used

in a PCMCIA revision 1 host. However, to minimize DC current drain through the pull-up resistor in normal

operation the pull-up should be turned off once the Reset signal has been actively driven low by the host.

Consequently, the input is specified as an I2Z because the resistor is not necessarily detectable in the input

current leakage test.

10) Host and card restrictions for CF Advanced Timing Modes and Ultra DMA modes: Additional Requirements for

CF Advanced Timing Modes and Ultra DMA Electrical Requirements for additional required limitations on the

implementation of CF Advanced Timing modes and Ultra DMA modes respectively.

Additional Requirements for CF Advanced Timing Modes

The CF Advanced Timing modes include PCMCIA I/O and Memory modes that are 100ns or faster and True

IDE PIO Modes 5,6 and Multiword DMA Modes 3,4.

When operating in CF Advanced timing modes, the host shall conform to the following requirements:

Only one CF device shall be attached to the CF Bus.

The host shall not present a load of more than 40pF to the device for all signals, including any cabling.

The maximum cable length is 0.15 m (6 in). The cable length is measured from the card connector to the host

controller. 0.46 m (18 in) cables are not supported.

The -WAIT and IORDY signals shall be ignored by the host.

Devices supporting CF Advanced timing modes shall also support slower timing modes, to ensure operability with

systems that do not support CF Advanced timing modes
