General Description
The A62S8308 is a low operating current 2,097,152-bit
static random access memory organized as 262,144
words by 8 bits and operates on a low power supply
voltage from 2.7V to 3.6V.
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
a device enable and an output enable input are included
for easy interfacing.
Data retention is guaranteed at a power supply voltage
as low as 2V.

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 CE1, a high CE2 and a low WE .
3. tWR is measured from the earliest of CE1 or WE going high or CE2 going low to the end of the Write cycle.
4. 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 CE1 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.
