The LY62256SL-70LL is a 256Kbit (32K x 8-bit) Low-Power CMOS Static RAM from Lyontek Inc. operating at 3.0V to 3.6V with 70 ns access time. It provides fully static operation with no clocks or refresh required, byte-wide I\/O, and data byte control via LB# and UB# signals for x16 variants. The LL (Low-power Low-voltage) variant features ultra-low standby current.<\/p>\n
