[GSI] Functional Description The GS882Z818/36B is an 8Mbit Synchronous Static SRAM. GSIs NBT SRAMs, like ZBT, NtRAM, NoBL or other pipelined read/double late write or flow through read/single late write SRAMs, allow utilization of all available bus bandwidth by eliminating the need to insert deselect cycles when the device is switched from read to write cycles. Features • 512K x 18 and 256K x 36 configurations • User-configurable Pipelined and Flow Through mode • NBT (No Bus Turn Around) functionality allows zero wait • Read-Write-Read bus utilization • Fully pin-compatible with both pipelined and flow through NtRAM™, NoBL™ and ZBT™ SRAMs • IEEE 1149.1 JTAG-compatible Boundary Scan • On-chip write parity checking; even or odd selectable • ZQ mode pin for user selectable high/low output drive strength. • x16/x32 mode with on-chip parity encoding and error detection • Pin-compatible with 2M, 4M and 16M devices • 3.3 V +10%/–5% core power supply • 2.5 V or 3.3 V I/O supply • LBO pin for Linear or Interleave Burst mode • Byte write operation (9-bit Bytes) • 3 chip enable signals for easy depth expansion • Clock Control, registered, address, data, and control • ZZ Pin for automatic power-down • JEDEC-standard 119-Bump BGA package
