The LY62L51216BML-45SLI is an 8Mbit (512K x 16-bit) ultra-low-power CMOS SRAM from Lyontek Inc. operating at 2.7V to 3.6V with 45 ns access time. It features upper\/lower byte control (LB#, UB#), data retention down to 1.5V, and standby current as low as 2.5 \u00b5A typical, making it ideal for battery-backed applications.<\/p>\n
