Very Low Power/Voltage CMOS SRAM
128K X 8 bit
BSI
BS62LV1025
DESCRIPTION
FEATURES
The BS62LV1025 is a high performance, very low power CMOS
Static Random Access Memory organized as 131,072 words by 8 bits
and operates from a wide range of 4.5V to 5.5V supply voltage.
Advanced CMOS technology and circuit techniques provide both high
speed and low power features with a typical CMOS standby current of
0.4uA and maximum access time of 55ns in 5V operation.
• Vcc operation voltage : 4.5V ~ 5.5V
• Very low power consumption :
Vcc = 5.0V C-grade : 35mA (Max.) operating current
I- grade : 40mA (Max.) operating current
0.4uA (Typ.) CMOS standby current
• High speed access time :
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 BS62LV1025 has an automatic power down feature, reducing the
power consumption significantly when chip is deselected.
