LP62S4096E-T Series
512K X 8 BIT LOW VOLTAGE CMOS SRAM
Features
General Description
„ Power supply range: 2.7V to 3.6V
„ Access times: 55ns / 70ns (max.)
„ Current:
Very low power version: Operating: 30mA (max.)
Standby:
10μA (max.)
„ Full static operation, no clock or refreshing required
„ All inputs and outputs are directly TTL-compatible
„ Common I/O using three-state output
„ Data retention voltage: 2V (min.)
„ Available in 32-pin TSSOP 36-ball CSP package
The LP62S4096E-T is a low operating current 4,194,304-bit
static random access memory organized as 524,288 words by 8
bits and operates on a low power supply range: 2.7V to 3.3V. 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.
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.

WE is high for Read Cycle.
Device is continuously enabled, CE1 = VIL or CE2= VIH.
Address valid prior to or coincident with CE1 transition low or CE2 transition high.
OE = VIL.
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) of a low CE1 or high CE2 , and a low WE .
3. tWR is measured from the earliest of CE1 or WE going high or CE2 going low WE going high to the end of the Write
cycle.
4. If the CE1 low or 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 level is high or low.
7. Transition is measured ±500mV from steady state. This parameter is sampled and not 100% tested.
