CY62138FV30 MoBL 2-Mbit (256 K 8) Static RAM 2-Mbit (256 K 8) Static RAM Features Functional Description Very high-speed: 45 ns The CY62138FV30 is a high performance CMOS static RAM organized as 256K words by 8 bits. This device features Temperature ranges advanced circuit design to provide ultra low active current. This Industrial: 40 C to 85 C is ideal for providing More Battery Life (MoBL ) in portable Automotive-A: 40 C to 85 C applications such as cellular telephones. The device also has an automatic power down feature that significantly reduces power Wide voltage range: 2.20 V to 3.60 V consumption. Place the device into standby mode reducing Pin compatible with CY62138CV25/30/33 power consumption when deselected (CE HIGH or CE LOW). 1 2 To write to the device, take Chip Enable (CE LOW and CE Ultra low standby power 1 2 HIGH) and Write Enable (WE) inputs LOW. Data on the eight I/O Typical standby current: 1 A pins (I/O through I/O ) is then written into the location specified 0 7 Maximum standby current: 5 A on the address pins (A through A ). 0 17 Ultra low active power To read from the device, take Chip Enable (CE LOW and CE 1 2 Typical active current: 1.6 mA at f = 1 MHz HIGH) and Output Enable (OE) LOW while forcing Write Enable (WE) HIGH. Under these conditions, the contents of the memory Easy memory expansion with CE , CE , and OE Features 1 2 location specified by the address pins appear on the I/O pins. Automatic power down when deselected The eight input and output pins (I/O through I/O ) are placed in 0 7 a high impedance state when the device is deselected (CE Complementary metal oxide semiconductor (CMOS) for 1 HIGH or CE LOW), the outputs are disabled (OE HIGH), or Optimum speed and power 2 during a write operation (CE LOW and CE HIGH and WE 1 2 Offered in Pb-free 36-ball VFBGA, 32-pin TSOP II, 32-pin LOW).
