2 / 9 page MOSEL-VITELIC MS62256H Pin Descriptions A0 - A14 Address Inputs These 15 address inputs select one of the 32768 8-bit words in the RAM. E Chip Enable Input E is active LOW. The chip enable must be active to read from or write to the device. If it is not active, the device is deselected and is in a standby power mode. The DQ pins will be in the high-impedance state when deselected. G Output Enable Input The output enable input is active LOW. If the output enable is active while the chip is selected and the write enable is inactive, data will be present on the DQ pins and they will be enabled. The DQ pins will be in the high impedance state when G is inactive. W Write Enable Input The write enable input is active LOW and controls read and write operations. With the chip enabled, when W is HIGH and G is LOW, output data will be present at the DQ pins; when W is LOW, the data present on the DQ pins will be written into the selected memory location. DQ0 - DQ7 Data Input/Output Ports These 8 bidirectional ports are used to read data from or write data into the RAM.

Stresses greater than those listed under ABSOLUTE MAXIMUM RATINGS may cause permanent damage to the device. This is a stress rating only and functional operation of the device at these or any other conditions above those indicated in the operational sections of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect reliability and degrade performance characteristics. |
