MX66C1024
5V Low Power CMOS SRAM 128 x 8 Bit
n DESCRIPTION
n FEATURES
The MX66C1024 is a high performance, extremely low power
CMOS
Static Random Access Memory organized as 131,072 words by 8
bits and operates at 5.0V supply voltage.
• Vcc operation voltage : 5V
• Low power consumption :
45mA (Max.) write current
2mA (Max.) read current
Advanced CMOS technology and circuit techniques provide both
high speed and low power features with a typical CMOS standby
current of 0.005uA and maximum access time of 70ns and 100ns
Easy memory expansion is provided by an active LOW chip
enable (CE1), an active HIGH chip enable (CE2), and active
LOW output enable (OE) and three-state output drivers.
The MX66C1024 has an automatic power down feature, reducing
the power consumption significantly when chip is deselected.
The MX66C1024 is available in the JEDEC standard 32 pin
SOP, STSOP and TSOP.
0.6uA (Typ.) CMOS standby current
• High speed access time :
-70

• Input levels are CMOS-compatible
• Automatic power down when chip is deselected
• Three state outputs
• Fully static operation
• Data retention supply voltage as low as 1.2V
• Easy expansion with CE2, CE1, and OE options
