General Description
The LP61L1024 is a low operating current 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. Two chip enable inputs are 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.

Notes: 1. 2. 3. 4.
tAS is measured from the address valid to the beginning of Write. A Write occurs during the overlap (tWP) of a low CE1, a high CE2 and a low WE . tWR is measured from the earliest of CE1 or WE going high or CE2 going low to the end of the Write cycle. If the CE1 low transition or the CE2 high transition occurs simultaneously 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 or CE2 going high 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.
