CY62147EV18 MoBL® 4-Mbit (256 K × 16) Static RAM 4-Mbit (256 K × 16) Static RAM 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 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 (I/O0 through I/O15) are placed in a high impedance state when the device is deselected (CE HIGH), the outputs are disabled (OE HIGH), both the Byte High Enable and the Byte Low Enable are disabled (BHE, BLE HIGH), or during an active write operation (CE LOW and WE LOW). Features ■ Very high speed: 55 ns ■ Wide voltage range: 1.65 V to 2.25 V ■ Pin compatible with CY62147DV18 ■ Ultra low standby power ❐ Typical standby current: 1 A ❐ Maximum standby current: 7 A ■ Ultra low active power ❐ Typical active current: 2 mA at f = 1 MHz ■ Ultra low standby power ■ Easy memory expansion with CE and OE features ■ Automatic power down when deselected ■ Complementary metal oxide semiconductor (CMOS) for optimum speed and power ■ Available in a Pb-free 48-ball very fine ball grid array (VFBGA) package 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 apears 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 11 for a complete description of read and write modes. Functional Description The CY62147EV18 is a high performance CMOS static RAM organized as 256 K words by 16 bits. This device features advanced circuit design to provide ultra low active current.

Test conditions for all parameters other than tri-state parameters assume signal transition time of 1 V/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 as shown in the “AC Test Loads and Waveforms” on page 5 section 16. In an earlier revision of this device, under a specific application condition, READ and WRITE operations were limited to switching of the byte enable and/or chip enable signals as described in the Application Notes AN13842 and AN66311. However, the issue has been fixed and in production now, and hence, these Application Notes are no longer applicable. They are available for download on our website as they contain information on the date code of the parts, beyond which the fix has been in production. 17. 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. 18. tHZOE, tHZCE, tHZBE, and tHZWE transitions are measured when the output enters a high impedence state 19. 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. 20. The minimum pulse width for write cycle 3 (WE controlled, OE LOW) should be equal to the sum of tSD and tHZWE.
