CY62147DV30 4-Mbit (256K x 16) Static RAM Features vanced circuit design to provide ultra-low active current. This is ideal for providing More Battery Life™ (MoBL®) in portable applications such as cellular telephones. The device also has an automatic power-down feature that significantly reduces power consumption. The device can also be put into standby mode reducing power consumption by more than 99% when deselected (CE HIGH or both BLE and BHE are HIGH). The input/output pins (I/O0 through I/O15) are placed in a high-impedance state when: deselected (CE HIGH), outputs are disabled (OE HIGH), both Byte High Enable and Byte Low Enable are disabled (BHE, BLE HIGH), or during a write operation (CE LOW and WE LOW). • Temperature Ranges — Industrial: –40°C to +85°C — Automotive-A: –40°C to +85°C — Automotive-E: –40°C to +125°C • Very high speed: 45 ns • Wide voltage range: 2.20V–3.60V • Pin-compatible with CY62147CV25, CY62147CV30, and CY62147CV33 Writing to the device is accomplished by taking Chip Enable (CE) and Write Enable (WE) inputs LOW. If Byte Low Enable (BLE) is LOW, then data from I/O pins (I/O0 through I/O7), is written into the location specified on the address pins (A0 through A17). If Byte High Enable (BHE) is LOW, then data from I/O pins (I/O8 through I/O15) is written into the location specified on the address pins (A0 through A17). • Ultra-low active power — Typical active current: 1.5 mA @ f = 1 MHz — Typical active current: 8 mA @ f = fmax • Ultra low standby power • Easy memory expansion with CE, and OE features • Automatic power-down when deselected Reading from the device is accomplished by taking Chip Enable (CE) and Output Enable (OE) LOW while forcing the Write Enable (WE) HIGH. If Byte Low Enable (BLE) is LOW, then data from the memory location specified by the address pins will appear on I/O0 to I/O7. If Byte High Enable (BHE) is LOW, then data from memory will appear on I/O8 to I/O15. See the truth table at the back of this data sheet for a complete description of read and write modes. • CMOS for optimum speed/power • Available in Pb-free and non Pb-free 48-ball VFBGA and non Pb-free 44-pin TSOPII • Byte power-down feature Functional Description[1] The CY62147DV30 is available in a 48-ball VFBGA, 44 Pin TSOPII packages.

At any given temperature and voltage condition, tHZCE is less than tLZCE, tHZBE is less than tLZBE, tHZOE is less than tLZOE, and tHZWE is less than tLZWE for any given device. 16. tHZOE, tHZCE, tHZBE, and tHZWE transitions are measured when the outputs enter a high impedence state. 17. The internal Write time of the memory is defined by the overlap of WE, CE = VIL, BHE and/or BLE = VIL. All signals must be ACTIVE to initiate a write and any of these signals can terminate a write by going INACTIVE. The data input set-up and hold timing should be referenced to the edge of the signal that terminates the write.
