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.

55ns (Max.) at Vcc = 5.0V  
70ns (Max.) at Vcc = 5.0V  
• Automatic power down when chip is deselected  
• Three state outputs and TTL compatible  
• Fully static operation  
The BS62LV1025 has an automatic power down feature, reducing the  
power consumption significantly when chip is deselected.  
The BS62LV1025 is available in DICE form, JEDEC standard 32 pin  
450mil Plastic SOP, 300mil Plastic SOJ, 600mil Plastic DIP,  
8mmx13.4mm STSOP and 8mmx20mm TSOP.  
• Data retention supply voltage as low as 1.5V  
• Easy expansion with CE2, CE1, and OE options
