The LY62W6416BML-45SLI is a 1Mbit (64K x 16-bit) ultra-low-power CMOS SRAM from Lyontek Inc. operating at 2.7V to 5.5V with 45 ns access time. The wide voltage range enables use in both 3.3V and 5V systems. The BML variant in 44-pin TSOP II package supports byte-wise control via LB# and UB# signals for upper\/lower byte selection.<\/p>\n

The device features upper\/lower byte control via LB# and UB# signals for flexible 8-bit or 16-bit bus access. Ultra-low standby current of 5 \u00b5A typical makes it suitable for battery-backed applications in both 3.3V and 5V systems.","working_principle":"The LY62W6416B is a fully static asynchronous SRAM with 16-bit data bus. LB# and UB# signals enable individual byte access: LB# low enables DQ0-DQ7 (lower byte), UB# low enables DQ8-DQ15 (upper byte). Both can be active simultaneously for full 16-bit access. Read: CE# low, OE# low, WE# high. Write: CE# low, WE# low with appropriate byte select. The wide supply range (2.7-5.5V) supports mixed-voltage system designs.","pin_description":"
