5V ± 5% power supplys for core I/O (VCC + VCCQ)  Double Word Write Control  Clock-controlled and registered addresses, data I/Os and control signals  Packaging: • 119 bump BGA package  Low capacitive bus loading WED2ZL64512S DESCRIPTION The WEDC SyncBurst - SRAM family employs highspeed, low-power CMOS designs that are fabricated using an advanced CMOS process.
WEDC’s 32Mb Sync SRAM integrate two 512K x 32 SRAMs into a single BGA package to provide 512K x 64 conﬁguration.
All synchronous inputs pass through registers controlled by a positive-edge-triggered single-clock input (CK).
The NBL or No Bus Latency Memory utilizes all the bandwidth in any combination of operating cycles.
Address, data inputs, and all control signals except output enable are synchronized to input clock.
Output Enable controls the outputs at any given time and to Asynchronous Input.
Write cycles are internally self-timed and initiated by the rising edge of the clock input.
This feature eliminates complex off-chip write pulse generation and provides increased timing ﬂexibility for incoming signals.
NOTE: NBL = No Bus Latency is equivalent to the industry ZBT™ devices.
