Table 15: Burst READ Cycle Timing Requirements
All tests performed with outputs configured for default setting of half drive strength, (BCR[5:4] = 01b).
Note:
1. A refresh opportunity must be provided every t
2. The High-Z timings measure a 100mV transition from either V
3. The Low-Z timings measure a 100mV transition away from the High-Z (VccQ/2) level toward either V
Address access time (fixed latency)
ADV# access time (fixed latency)
Burst to READ access time (variable latency)
CLK to output delay
Address hold from ADV# HIGH(fixed latency)
Burst OE# LOW to output delay
CE# HIGH between subsequent burst or mixed mode
operations
Maximum CE# pulse width
CE# or ADV# LOW to WAIT valid
CLK period
Chip select access time (fixed latency)
CE# setup time to active CLK edge
Hold time from active CLK edge
Chip disable to DQ and WAIT High-Z output
CLK rise or fall time
CLK to WAIT valid
Output HOLD from CLK
CLK HIGH or LOW time
Output disable to DQ High-Z output
Output enable to Low-Z output
Setup time to active CLK edge
Parameter
HIGH, or b) CE# HIGH for longer than 15ns.
CEM
. A refresh opportunity is satisfied by either of the following two conditions: a) clocked CE#
