LP621024E-I Series
128K X 8 BIT CMOS SRAM
Features
General Description
„ Single +5V power supply
„ Access times: 55/70 ns (max.)
„ Current:
Very low power version: Operating: 70mA (max.)
Standby:
50μA (max.)
„ Full static operation, no clock or refreshing required
„ All inputs and outputs are directly TTL-compatible
„ Common I/O using three-state output
„ Output enable and two chip enable inputs for easy
application
„ Data retention voltage: 2V (min.)
„ Available in 32-pin SOP, TSOP and TSSOP
(8 X 13.4mm) packages
„ Pb-Free package only
„ All Pb-free (Lead-free) products are RoHS compliant
The LP621024E-I 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 5V 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 2V.

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 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.
