The UT9Q512K32 has three control inputs called Enable 1 (En), Write Enable (Wn), and Output Enable (G); 19 address inputs, A(18:0); and eight bidirectional data lines, DQ(7:0). En Device Enable controls device selection, active, and standby modes. Asserting En enables the device, causes IDD to rise to its active value, and decodes the 19 address inputs to select one of 524,288 words in the memory. Wn controls read and write operations. During a read cycle, G must be asserted to enable the outputs.
