47V CY62147CV25/30/33 MoBL™ 256K x 16 Static RAM Features • High Speed — 55 ns and 70 ns availability • Voltage range: — CY62147CV25: 2.2V–2.7V — CY62147CV30: 2.7V–3.3V — CY62147CV33: 3.0V–3.6V • Pin Compatible with CY62147V • Ultra-low active power — Typical active current: 1.5 mA @ f = 1 MHz • • • • — Typical active current: 5.5 mA @ f = fmax (70 ns speed) Low standby power Easy memory expansion with CE and OE features Automatic power-down when deselected CMOS for optimum speed/power cantly reduces power consumption by 80% when addresses are not toggling. 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). 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). 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. The CY62147CV25/30/33 are available in a 48-ball FBGA package. Functional Description The CY62147CV25/30/33 are high-performance CMOS static RAMs organized as 256K words by 16 bits.

Test conditions assume signal transition time of 5 ns or less, timing reference levels of VCC(typ.)/2, input pulse levels of 0 to VCC(typ.), and output loading of the specified IOL/IOH and 30-pF load capacitance. 9. 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. 10. If both byte enables are toggled together this value is 10 ns. 11. tHZOE, tHZCE, tHZBE, and tHZWE transitions are measured when the outputs enter a high impedance state. 12. 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.
