DESCRIPTION
The BH62UV1601 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/25
O
C and maximum access time of 55ns at
1.65V/85
O
C.
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 BH62UV1601 has an automatic power down feature, reducing
the power consumption significantly when chip is deselected.
The BH62UV1601 is made with two chips of 8Mbit SRAM by stacked
multi-chip-package.
The BH62UV1601 is available in 48-ball BGA package.
