The SNR008 is a signal power, 8M-bit, read only memory. It is organized as 1M bytes, operates for single 3V power supply, support static standby mode. The SNR008 embedded two different interfaces, one is a standard 8-bit interface bus which compatible with SNL310, another one is a special 8-bit AD (address/data) bus which compatible with SNC710. SNR008 offers automatic power-down, with power-down controlled by the chip enable “CE\”. When chip enable goes to high, SNR008 will entry power-down mode in order to save the power consumption.
