General Description
The chip enable input is provided for POWER-DOWN,
device enable. Two byte enable inputs and an output
enable input are included for easy interfacing.
Data retention is guaranteed at a power supply voltage
as low as 2V.
The A62S8316 is a low operating current 4,194,304-bit
static random access memory organized as 262,144
words by 16 bits and operates on low power supply
voltage from 2.7V to 3.6V. It is built using AMIC’s high
performance CMOS process.
Inputs and three-state outputs are TTL compatible and
allow for direct interfacing with common system bus
structures.

2. Device is continuously enabled CE = VIL, HB = VIL and, or LB = VIL.
3. Address valid prior to or coincident with CE and ( HB and, or LB ) transition low.
4. OE = VIL.
5. Transition is measured ±500mV from steady state. This parameter is sampled and not 100% tested.

Notes: 1. tAS is measured from the address valid to the beginning of Write.
2. A Write occurs during the overlap (tWP, tBW) of a low CE , WE and ( HB and, or LB ).
3. tWR is measured from the earliest of CE or WE or ( HB and, or LB ) going high to the end of the Write cycle.
4. OE level is high or low.
5. Transition is measured ±500mV from steady state. This parameter is sampled and not 100% tested.
