CY62167DV30 MoBL 16-Mbit (1 M 16) Static RAM 16-Mbit (1 M 16) Static RAM automatic power-down feature that significantly reduces power Features consumption by 99% when addresses are not toggling. The device can also be put into standby mode when deselected (CE Thin small outline package (TSOP-I) configurable as 1 HIGH or CE LOW or both BHE and BLE are HIGH). The 1 M 16 or as 2 M 8 SRAM 2 input/output pins (I/O through I/O ) are placed in a 0 15 Wide voltage range: 2.2 V3.6 V high-impedance state when: deselected (CE HIGH or CE 1 2 LOW), outputs are disabled (OE HIGH), both Byte High Enable Ultra-low active power: and Byte Low Enable are disabled (BHE, BLE HIGH), or during Typical active current: 2 mA at f = 1 MHz a Write operation (CE LOW, CE HIGH and WE LOW). 1 2 Ultra-low standby power Writing to the device is accomplished by taking Chip Enables (CE LOW and CE HIGH) and Write Enable (WE) input LOW. If Easy memory expansion with CE , CE and OE features 1 2 1 2 Byte Low Enable (BLE) is LOW, then data from I/O pins (I/O 0 Automatic power-down when deselected through I/O ), is written into the location specified on the address 7 pins (A through A ). If Byte High Enable (BHE) is LOW, then 0 19 Complementary metal oxide semiconductor (CMOS) for data from I/O pins (I/O through I/O ) is written into the location 8 15 optimum speed / power specified on the address pins (A through A ). 0 19 Available in Pb-free and non Pb-free 48-ball very fine-pitch ball Reading from the device is accomplished by taking Chip Enables grid array (VFBGA) and 48-pin TSOP I package (CE LOW and CE HIGH) and Output Enable (OE) LOW while 1 2 forcing the Write Enable (WE) HIGH. If Byte Low Enable (BLE) Functional Description is LOW, then data from the memory location specified by the address pins appear on I/O to I/O . If Byte High Enable (BHE) 0 7 The CY62167DV30 is a high-performance CMOS static RAM is LOW, then data from memory appear on I/O to I/O . See the 8 15 organized as 1M words by 16-bits. This device features truth table at the back of this data sheet for a complete advanced circuit design to provide ultra-low active current.
