M5M5V5636GP –16 18874368-BIT(524288-WORD BY 36-BIT) NETWORK SRAM DESCRIPTION The M5M5V5636GP is a family of 18M bit synchronous SRAMs organized as 524288-words by 36-bit. It is designed to eliminate dead bus cycles when turning the bus around between reads and writes, or writes and reads. Mitsubishi's SRAMs are fabricated with high performance, low power CMOS technology, providing greater reliability. M5M5V5636GP operates on 3.3V power/ 2.5V I/O supply or a single 3.3V power supply and are 3.3V CMOS compatible. APPLICATION High-end networking products that require high bandwidth, such as switches and routers. FUNCTION Synchronous circuitry allows for precise cycle control triggered by a positive edge clock transition. Synchronous signals include : all Addresses, all Data Inputs, all Chip Enables (E1#, E2, E3#), Address Advance/Load (ADV), Clock Enable (CKE#), Byte Write Enables (BWa#, BWb#, BWc#, BWd#) and Read/Write (W#). Write operations are controlled by the four Byte Write Enables (BWa# - BWd#) and Read/Write(W#) inputs. All writes are conducted with on-chip synchronous selftimed write circuitry. Asynchronous inputs include Output Enable (G#), Clock (CLK) and Snooze Enable (ZZ). The HIGH input of ZZ pin puts the SRAM in the power-down state.The Linear Burst order (LBO#) is DC operated pin. LBO# pin will allow the choice of eit...
