32K X 8 BIT LOW VOLTAGE CMOS SRAM
General Description
Preliminary
Features
n External Operating Voltage: 2.7V to 3.6V
n Access times: 55ns (max.): for VCC = 3.0V to 3.6V
70ns (max.): for VCC = 2.7V to 3.6V
n Current: Operating (ICC1): -55 series 18mA (typ.)
-70 series 12mA (typ.)
Standby (ISB1): 0.05mA (typ.)
n Extended operating temperature range: -40ºC to
+85ºC for -LLU series
The A62L256 is a low operating current 262,144-bit static
random access memory organized as 32,768 words by 8
bits and operates on a low power voltage: 2.7V to 3.6V.
Inputs and three-state outputs are TTL compatible and
allow for direct interfacing with common system bus
structures.
Minimum standby power is drawn by this device when
CE is at a high level, independent of the other input
n Full static operation, no clock or refreshing required
n All inputs and outputs are directly TTL-compatible
n Common I/O using three-state output
n Data retention voltage: 2.0V (min.)
levels.
Data retention is guaranteed at a power supply voltage
as low as 2.0V.
n Available in 28-pin DIP, SOP and TSOP (forward and
reverse type) packages
