Functional Description
The V62C3802048L is a low power CMOS Static RAM organized as 262,144 words by 8 bits. 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 automatic power-down mode feature when deselected. Writing to the device is accomplished by taking Chip Enable 1 (CE1) with Write Enable (WE ) LOW, and Chip Enable 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-impedance state when the device is deselected: the outputs are disabled during a write cycle. The V62C3802048LL comes with a 1V data retention feature and Lower Standby Power. The V62C3802048L is available in a 32-pin 8 x 20 mm TSOP1/8 x 13.4mm STSOP and CSP type 48-fpBGA packages.
