CY62137FV30 MoBL® 2-Mbit (128K x 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 by 90% 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 in the following conditions: Features ■ 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 ■ Wide voltage range: 2.20V–3.60V ■ Pin compatible with CY62137CV/CV25/CV30/CV33, CY62137V, and CY62137EV30 ■ 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) ■ Ultra low standby power ❐ Typical standby current: 1 μA ❐ Maximum standby current: 5 μA (Industrial) ■ Ultra low active power ❐ Typical active current: 1.6 mA at f = 1 MHz (45 ns speed) ■ Easy memory expansion with CE and OE features ■ Automatic power down when deselected ■ CMOS for optimum speed and power ■ Byte power down feature ■ Available in Pb free 48-Ball VFBGA and 44-pin TSOP II package Write to the device by taking 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 A16). 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 A16). Read from the device 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 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 CY62137FV30 is a high performance CMOS static RAM organized as 128K words by 16 bits.

Test conditions for all parameters, other than tri-state parameters, assume signal transition time of 3 ns (1V/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 “AC Test Loads and Waveforms” on page 4. 12. AC timing parameters are subject to byte enable signals (BHE or BLE) not switching when chip is disabled. Please see application note AN13842 for further clarification. 13. 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. 14. tHZOE, tHZCE, tHZBE, and tHZWE transitions are measured when the outputs enter a high impedance state. 15. If both byte enables are toggled together, this value is 10 ns. 16. The internal write time of the memory is defined by the overlap of WE, CE = VIL, BHE and/or BLE = VIL. All signals are ACTIVE to initiate a write and any of these signals terminate a write by going INACTIVE. The data input setup and hold timing are referenced to the edge of the signal that terminates the write.
