IS62C1024L
128K x 8 LOW POWER CMOS STATIC RAM
FEATURES
DESCRIPTION
The ICSI IS62C1024L is a low power,131,072-word by 8-bit
CMOS static RAM. It is fabricated using ICSI's high-
performance CMOS technology. This highly reliable process
coupled with innovative circuit design techniques, yields higher
performance and low power consumption devices.
High-speed access time: 35, 45, 55, 70 ns
Low active power: 450 mW (typical)
Low standby power: 150 µW (typical) CMOS
standby
Output Enable (OE) and two Chip Enable
(CE1 and CE2) inputs for ease in applications
When CE1 is HIGH or CE2 is LOW (deselected), the device
assumes a standby mode at which the power dissipation can
be reduced by using CMOS input levels.
Fully static operation: no clock or refresh
required
Easy memory expansion is provided by using two Chip Enable
inputs, CE1 and CE2. The active LOW Write Enable (WE)
controls both writing and reading of the memory.
TTL compatible inputs and outputs
Single 5V (±10%) power supply
The IS62C1024L is available in 32-pin 600mil DIP, 450mil SOP
and 8*20mm TSOP-1 packages.

Notes:
1. Stress greater than those listed under ABSOLUTE MAXIMUM RATINGS may cause
permanent damage to the device. This is a stress rating only and functional operation of the
device at these or any other conditions above those indicated in the operational sections of
this specification is not implied. Exposure to absolute maximum rating conditions for

and output loading specified in Figure 1a.
2. Tested with the load in Figure 1b. Transition is measured ±500 mV from steady-state voltage. Not 100% tested.
3. The internal write time is defined by the overlap of CE1 LOW, CE2 HIGH and WE LOW. All signals must be in valid states to
initiate a Write, but any one can go inactive to terminate the Write. The Data Input Setup and Hold timing are referenced to the
rising or falling edge of the signal that terminates the Write.
4. Tested with OE HIGH.
