CY62147EV30 MoBL® 4-Mbit (256K x 16) Static RAM Features 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 percent when deselected (CE HIGH or both BLE and BHE are HIGH). The input and output pins (I/O0 through I/O15) are placed in a high impedance state when: Very high speed: 45 ns Temperature ranges ❐ Industrial: –40 °C to +85 °C ■ Wide voltage range: 2.20 V to 3.60 V ■ Pin compatible with CY62147DV30 ■ Ultra low standby power ❐ Typical standby current: 1 A ❐ Maximum standby current: 7 A (Industrial) ■ Ultra low active power ❐ Typical active current: 2 mA at f = 1 MHz [1] and OE features ■ Easy memory expansion with CE ■ ■ ■ Automatic power-down when deselected ■ Complementary metal oxide semiconductor (CMOS) for optimum speed and power ■ Available in Pb-free 48-ball very fine ball grid array (VFBGA) (single/dual CE option) and 44-pin thin small outline package (TSOP) II packages ■ Byte power-down feature ■ Deselected (CE HIGH) ■ Outputs are disabled (OE HIGH) ■ Both Byte High Enable and Byte Low Enable are disabled (BHE, BLE HIGH) ■ Write operation is active (CE LOW and WE LOW) 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 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). 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 I/O0 to I/O7. If Byte High Enable (BHE) is LOW, then data from memory appears on I/O8 to I/O15. See the Truth Table on page 10 for a complete description of read and write modes. For best practice recommendations, refer to the Cypress application note AN1064, SRAM System Guidelines. Functional Description The CY62147EV30 is a high performance CMOS static RAM (SRAM) organized as 256K words by 16 bits.
