General Description
The chip enable input is provided for POWER-DOWN
and device enable and an output enable input is included
for easy interfacing.
Data retention is guaranteed at a power supply voltage
as low as 2.0V.
The LP61L1008A is a high speed 1,048,576-bit static
random access memory organized as 131,072 words by
8 bits and operates on a single 3.3V power supply.
Inputs and three-state outputs are TTL compatible and
allow for direct interfacing with common system bus
structures.

Notes: 1. tAS is measured from the address valid to the beginning of Write.
2. A Write occurs during the overlap (tWP) of a low CE and a low WE .
3. tWR is measured from the earliest of CE or WE going high to the end of the Write cycle.
4. If the CE low transition with the WE low transition or after the WE transition, outputs remain in a high
impedance state.
5. tCW is measured from the later of CE going low to the end of Write.
6. OE is continuously low. ( OE = VIL)
7. Transition is measured ±500mV from steady state. This parameter is sampled and not 100% tested.
