DESCRIPTION
The 1+51 IC62C1024 is a low power,131,072-word by 8-bit
CMOS static RAM. It is fabricated using 1+51's high-
performance CMOS technology. This highly reliable process
coupled with innovative circuit design techniques, yields higher
performance and low power consumption devices.
When CE1 is HIGH or CE2 is LOW (deselected), the device
assumes a standby mode at which the power dissipation can
be reduced by using CMOS input levels.
Easy memory expansion is provided by using two Chip Enable
inputs, CE1 and CE2. The active LOW Write Enable (WE)
controls both writing and reading of the memory.
The IC62C1024 is available in 32-pin 600mil DIP, 450mil SOP
and 8*20mm TSOP-1 packages.

Notes:
1. WE is HIGH for a Read Cycle.
2. The device is continuously selected. OE, CE1 = VIL, CE2 = VIH.
3. Address is valid prior to or coincident with CE1 LOW and CE2 HIGH transitions.
