CY62148EV30 MoBL 4-Mbit (512 K 8) Static RAM 4-Mbit (512 K 8) Static RAM Features Functional Description Very high speed: 45 ns The CY62148EV30 is a high performance CMOS static RAM organized as 512 K words by 8 bits. This device features Wide voltage range: 2.20 V to 3.60 V advanced circuit design to provide ultra low active current. This Temperature range: is ideal for providing More Battery Life (MoBL ) in portable Industrial: 40 C to +85 C applications such as cellular telephones. The device also has an Automotive-A: 40 C to +85 C automatic power down feature that significantly reduces power consumption. Placing the device into standby mode reduces Pin compatible with CY62148DV30 power consumption by more than 99 percent when deselected (CE HIGH). The eight input and output pins (I/O through I/O ) Ultra low standby power 0 7 are placed in a high impedance state when the device is Typical standby current: 1 A deselected (CE HIGH), the outputs are disabled (OE HIGH), or Maximum standby current: 7 A (Industrial) during a write operation (CE LOW and WE LOW). Ultra low active power To write to the device, take Chip Enable (CE) and Write Enable Typical active current: 2 mA at f = 1 MHz (WE) inputs LOW. Data on the eight I/O pins (I/O through I/O ) 0 7 is then written into the location specified on the address pins (A Easy memory expansion with CE and OE features 0 through A ). 18 Automatic power down when deselected To read from the device, take Chip Enable (CE) and Output Complementary metal oxide semiconductor (CMOS) for Enable (OE) LOW while forcing Write Enable (WE) HIGH. Under optimum speed and power these conditions, the contents of the memory location specified by the address pins appear on the I/O pins. Available in Pb-free 36-ball very fine-pitch ball grid array (VFBGA), 32-pin thin small outline package (TSOP) II, and 1 32-pin small outline integrated circuit (SOIC) packages Logic Block Diagram I/O 0 A 0 INPUT BUFFER IO 0 A 1 I/O 1 A 2 IO 1 A 3 I/O 2 A 4 IO 2 A 5 I/O 3 A 6 512K x 8 IO 3 A 7 I/O 4 A 8 ARRAY IO 4 A 9 I/O 5 A 10 IO 5 A 11 I/O 6 A 12 IO 6 I/O 7 CE POWER IO 7 COLUMN DECODER WE DOWN OE Note 1.
