CY62147EV30 MoBL® 4-Mbit (256K x 16) Static RAM ■ Very high speed: 45 ns ■ Temperature ranges ❐ Industrial: –40°C to +85°C ❐ Automotive-A: –40°C to +85°C ❐ Automotive-E: –40°C to +125°C 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 when addresses are not toggling. Placing the device into standby mode reduces power consumption by more than 99% when deselected (CE HIGH or both BLE and BHE are HIGH). The input and output pins (IO0 through IO15) are placed in a high impedance state when: ■ Wide voltage range: 2.20V to 3.60V ■ Deselected (CE HIGH) ■ Pin compatible with CY62147DV30 ■ Outputs are disabled (OE HIGH) ■ Ultra low standby power ❐ Typical standby current: 1 μA ❐ Maximum standby current: 7 μA (Industrial) ■ Both Byte High Enable and Byte Low Enable are disabled (BHE, BLE HIGH) ■ Write operation is active (CE LOW and WE LOW) ■ Ultra low active power ❐ Typical active current: 2 mA at f = 1 MHz ■ Easy memory expansion with CE [1] and OE features ■ Automatic power down when deselected ■ CMOS for optimum speed and power To write to the device, take Chip Enable (CE) and Write Enable (WE) inputs LOW. If Byte Low Enable (BLE) is LOW, then data from IO pins (IO0 through IO7) is written into the location specified on the address pins (A0 through A17). If Byte High Enable (BHE) is LOW, then data from IO pins (IO8 through IO15) is written into the location specified on the address pins (A0 through A17). ■ Available in Pb-free 48-ball VFBGA (single/dual CE option) and 44-pin TSOPII packages ■ Byte power down feature Features To read from the device, take 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 appear on IO0 to IO7. If Byte High Enable (BHE) is LOW, then data from memory appears on IO8 to IO15. See the Truth Table on page 9 for a complete description of read and write modes. Functional Description The CY62147EV30 is a high performance CMOS static RAM organized as 256K words by 16 bits. This device features advanced circuit design to provide ultra low active current. It is Logic Block Diagram For best practice recommendations, refer to the Cypress application note AN1064, SRAM System Guidelines.

AC timing parameters are subject to byte enable signals (BHE or BLE) not switching when chip is disabled. See application note AN13842 for further clarification. 14. At any 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 device. 15. tHZOE, tHZCE, tHZBE, and tHZWE transitions are measured when the outputs enter a high impedance state. 16. The internal write time of the memory is defined by the overlap of WE, CE = VIL, BHE, BLE, or both = 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 setup and hold timing must be referenced to the edge of the signal that terminates the write.
