Easy memory expansion is provided by an active LOW CE1 , an active HIGH CE2, an active LOW OE, and Tri-state I/O’s. This device has an a- utomatic power-down mode feature when deselected. Writing to the device is accomplished by taking Chip E- nable 1 (CE1 ) with Write Enable (WE) LOW, and Chip En- able 2 (CE2) HIGH. Reading from the device is performed by taking Chip Enable 1 (CE1) with Output Enable (OE) LOW while Write Enable (WE) and Chip Enable 2 (CE2) is HIGH. The I/O pins are placed in a high-imped- ance state when the device is deselected: the outputs are d- isabled during a write cycle. TheV62C2801024LL comes with a 1V data retention feature and Lower Standby Power. The V62C2801024L is available in a 32pin 8 x 20 mm TSOP1 / STSOP / 48-fpBGA packages. 32-Pin TSOP1 / STSOP / 48-fpBGA (See nest page) Logic Block Diagram 1024 X 1024 INPUT BUFFER COLUMN DECODER CONTROL CIRCUIT I/O8 I/O1 OE WE CE1 CE2 A10 A11 A12 A13 A14 A15 A16 A8 A7 A6 A5 A4 A3 A2 A1 A0 A9 REV. 1.1 April 2001 V62C2801024L(L) 1 |
