MoBL® CY62128E 1-Mbit (128K x 8) Static RAM Features Functional Description The CY62128E[1] is a high performance CMOS static RAM organized as 128K words by 8 bits. This device features advanced circuit design to provide ultra low active current. This 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 percent when deselected (CE1 HIGH or CE2 LOW). The eight input and output pins (IO0 through IO7) are placed in a high impedance state when the device is deselected (CE1 HIGH or CE2 LOW), the outputs are disabled (OE HIGH), or a write operation is in progress (CE1 LOW and CE2 HIGH and WE LOW) ■ 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 ■ Voltage range: 4.5V to 5.5V ■ Pin compatible with CY62128B ■ Ultra low standby power ❐ Typical standby current: 1 μA ❐ Maximum standby current: 4 μA (Industrial) ■ Ultra low active power ❐ Typical active current: 1.3 mA at f = 1 MHz ■ Easy memory expansion with CE1, CE2, and OE features ■ Automatic power down when deselected ■ CMOS for optimum speed and power ■ Offered in standard Pb-free 32-pin STSOP, 32-pin SOIC, and 32-pin TSOP I packages To write to the device, take Chip Enable (CE1 LOW and CE2 HIGH) and Write Enable (WE) inputs LOW. Data on the eight IO pins (IO0 through IO7) is then written into the location specified on the address pins (A0 through A16). To read from the device, take Chip Enable (CE1 LOW and CE2 HIGH) and Output Enable (OE) LOW while forcing Write Enable (WE) HIGH. Under these conditions, the contents of the memory location specified by the address pins appear on the IO pins.

Test conditions for all parameters other than tri-state parameters assume signal transition time of 3ns (1V/ns) or less, timing reference levels of 1.5V, input pulse levels of 0 to 3V, and output loading of the specified IOL/IOH as shown in the “” on page 4. 13. At any given temperature and voltage condition, tHZCE is less than tLZCE, tHZOE is less than tLZOE, and tHZWE is less than tLZWE for any given device. 14. tHZOE, tHZCE, and tHZWE transitions are measured when the outputs enter a high impedance state. 15. The internal Write time of the memory is defined by the overlap of WE, CE = 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.
