n DESCRIPTION
The BH62UV1600 is a high performance, ultra low power CMOS Static
Random Access Memory organized as 2,048K by 8 bits and operates in
a wide range of 1.65V to 3.6V supply voltage.
Advanced CMOS technology and circuit techniques provide both high
speed and low power features with typical operating current of 1.5mA at
1MHz at 3.6V/25OC and maximum access time of 70ns at 1.8V/85OC.
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 BH62UV1600 has an automatic power down feature, reducing the
power consumption significantly when chip is deselected.
The BH62UV1600 is made with two chips of 8Mbit SRAM by stacked
multi-chip-package.
The BH62UV1600 is available 48-ball BGA package.

NOTES:
1. WE is high in read Cycle.
2. Device is continuously selected when CE1 = VIL and CE2= VIH.
3. Address valid prior to or coincident with CE1 transition low and/or CE2 transition high.
4. OE = VIL.
5. Transition is measured ± 500mV from steady state with CL = 5pF.
The parameter is guaranteed but not 100% tested.
