IS61C512
IS61C512
64K x 8 HIGH-SPEED CMOS STATIC RAM
DESCRIPTION
The
ICSI
IS61C512 is a very high-speed, low power, 65,536
word by 8-bit CMOS static RAMs. They are fabricated using
ICSI
's high-performance CMOS technology. This highly
reliable process coupled with innovative circuit design
techniques, yields higher performance and low power con-
sumption devices.
When
CE1
is HIGH or CE2 is LOW (deselected), the device
assumes a standby mode at which the power dissipation can
be reduced down to 1 mW (typical) with CMOS input levels.
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.
The IS61C512 is available in 32-pin 300mil DIP, SOJ and
8*20mm TSOP-1 packages.
FEATURES
Pin compatible with 128K x 8 devices
High-speed access time: 15, 20, 25, 35 ns
Low active power: 500 mW (typical)
Low standby power
— 250 µW (typical) CMOS standby
Output Enable (OE) and two Chip Enable
(CE1 and CE2) inputs for ease in applications
Fully static operation: no clock or refresh
required
TTL compatible inputs and outputs
Single 5V (±10%) power supply
