CY62177DV30 MoBL 32-Mbit (2 M 16) Static RAM automatic power-down feature that significantly reduces power Features consumption. The device can also be put into standby mode when deselected (CE HIGH or CE LOW or both BHE and BLE Very high speed: 55 ns 1 2 are HIGH). The input/output pins (I/O through I/O ) are placed 0 15 Wide voltage range: 2.20 V3.60 V in a 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 Typical active current: 15 mA at f = f max Writing to the device is accomplished by taking Chip Enables Ultra low standby power (CE LOW and CE HIGH) and Write Enable (WE) input LOW. If 1 2 Byte Low Enable (BLE) is LOW, then data from I/O pins (I/O 0 Easy memory expansion with CE , CE and OE features 1 2 through I/O ), is written into the location specified on the address 7 Automatic power-down when deselected pins (A through A ). If Byte High Enable (BHE) is LOW, then 0 20 data from I/O pins (I/O through I/O ) is written into the location 8 15 Complementary metal oxide semiconductor (CMOS) for specified on the address pins (A through A ). 0 20 optimum speed/power Reading from the device is accomplished by taking Chip Enables Packages offered in a 48-ball fine ball grid array (FBGA) (CE LOW and CE HIGH) and Output Enable (OE) LOW while 1 2 forcing the Write Enable (WE) HIGH. If Byte Low Enable (BLE) is LOW, then data from the memory location specified by the Functional Description address pins will appear on I/O to I/O . If Byte High Enable 0 7 The CY62177DV30 is a high-performance CMOS static RAM (BHE) is LOW, then data from memory will appear on I/O to 8 organized as 2M words by 16 bits. This device features I/O .
