BS62LV2563JC Overview

Very Low Power/Voltage CMOS SRAM 32K X 8 bit

BSI
FEATURES
Very Low Power/Voltage CMOS SRAM
32K X 8 bit
DESCRIPTION
BS62LV2563
• Wide Vcc operation voltage : 2.4V ~ 3.6V
• Very low power consumption :
Vcc = 3.0V C-grade : 20mA (Max.) operating current
I- grade : 25mA (Max.) operating current
0.01uA (Typ.) CMOS standby current
• High speed access time :
-70
70ns (Max.) at Vcc = 3.0V
• Automatic power down when chip is deselected
• Three state outputs and TTL compatible
• Fully static operation
• Data retention supply voltage as low as 1.5V
• Easy expansion with CE and OE options
The BS62LV2563 is a high performance, very low power CMOS
Static Random Access Memory organized as 32,768 words by 8 bits
and operates from a wide range of 2.4V to 3.6V supply voltage.
Advanced CMOS technology and circuit techniques provide both high
speed and low power features with a typical CMOS standby current of
0.01uA and maximum access time of 70ns in 3V operation.
Easy memory expansion is provided by an active LOW chip
enable (CE), and active LOW output enable (OE) and three-state
output drivers.
The BS62LV2563 has an automatic power down feature, reducing the
power consumption significantly when chip is deselected.
The BS62LV2563 is available in the JEDEC standard 28 pin
330mil Plastic SOP, 300mil Plastic SOJ, 600mil Plastic DIP and
8mmx13.4mm TSOP (normal type).
