DESCRIPTION
The BS616UV4010 is a high performance, Ultra low power CMOS Static
Random Access Memory organized as 262,144 words by 16 bits and
operates from a wide range of 1.8V 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 0.20uA and maximum access time of 70/100ns in 2.0V 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 BS616UV4010 has an automatic power down feature, reducing the
power consumption significantly when chip is deselected.
The BS616UV4010 is available in DICE form, JEDEC standard 44-pin
TSOP Type 2 package and 48-pin BGA package.

NOTES:
1. WE is high in read Cycle.
2. Device is continuously selected when CE = VIL.
3. Address valid prior to or coincident with CE transition low.
4. OE = VIL .
5. Transition is measured ± 500mV from steady state with CL = 5pF as shown in Figure 1B.
The parameter is guaranteed but not 100% tested.
