CY62126ESL MoBL 1-Mbit (64 K 16) Static RAM 1-Mbit (64 K 16) Static RAM addresses are not toggling. Placing the device into standby Features mode reduces power consumption by more than 99 percent when deselected (CE HIGH). The input and output pins (I/O Very high speed: 45 ns 0 through I/O ) are placed in a high impedance state when the 15 Wide voltage range: 2.2 V to 3.6 V and 4.5 V to 5.5 V device is deselected (CE HIGH), the outputs are disabled (OE HIGH), both Byte High Enable and Byte Low Enable are disabled Ultra low standby power (BHE, BLE HIGH) or during a write operation (CE LOW and WE Typical standby current: 1 A LOW). Maximum standby current: 4 A To write to the device, take Chip Enable (CE) and Write Enable Ultra low active power (WE) inputs LOW. If Byte Low Enable (BLE) is LOW, then data Typical active current: 1.3 mA at f = 1 MHz from I/O pins (I/O through I/O ) is written into the location 0 7 specified on the address pins (A through A ). If Byte High 0 15 Easy memory expansion with CE, and OE features Enable (BHE) is LOW, then data from I/O pins (I/O through 8 Automatic power down when deselected I/O ) is written into the location specified on the address pins 15 (A through A ). 0 15 Complementary metal oxide semiconductor (CMOS) for To read from the device, take Chip Enable (CE) and Output optimum speed and power Enable (OE) LOW while forcing the Write Enable (WE) HIGH. If Available in Pb-free 44-pin thin small outline package (TSOP) Byte Low Enable (BLE) is LOW, then data from the memory Type II package location specified by the address pins appear on I/O to I/O . If 0 7 Byte High Enable (BHE) is LOW, then data from memory Functional Description appears on I/O to I/O . See the Truth Table on page 11 for a 8 15 complete description of read and write modes. The CY62126ESL is a high performance CMOS static RAM The CY62126ESL device is suitable for interfacing with organized as 64K words by 16 bits. This device features processors that have TTL I/P levels. It is not suitable for advanced circuit design to provide ultra low active current. This processors that require CMOS I/P levels. Please see Electrical is ideal for providing More Battery Life (MoBL ) in portable Characteristics on page 4 for more details and suggested applications. The device also has an automatic power down alternatives. feature that significantly reduces power consumption when Logic Block Diagram DATA IN DRIVERS A 10 A 9 A 8 A 7 A 64 K 16 6 A 5 I/O I/O RAM Array 0 7 A 4 A 3 I/O I/O 8 15 A 2 A 1 A 0 COLUMN DECODER BHE WE CE OE BLE Cypress Semiconductor Corporation 198 Champion Court San Jose, CA 95134-1709 408-943-2600 Document Number: 001-45076 Rev. *F Revised June 4, 2013 ROW DECODER A 11 A 12 A 13 A 14 A 15 SENSE AMPS CY62126ESL MoBL Contents Pin Configuration .............................................................3 Truth Table ...................................................................... 11 Product Portfolio ..............................................................3 Ordering Information ...................................................... 12 Maximum Ratings .............................................................4 Ordering Code Definitions ......................................... 12 Operating Range ...............................................................4 Package Diagram ............................................................ 13 Electrical Characteristics .................................................4 Acronyms ........................................................................14 Capacitance ......................................................................5 Document Conventions ................................................. 14 Thermal Resistance ..........................................................5 Units of Measure ....................................................... 14 AC Test Loads and Waveforms .......................................5 Document History Page ................................................. 15 Data Retention Characteristics .......................................6 Sales, Solutions, and Legal Information ...................... 16 Data Retention Waveform ................................................6 Worldwide Sales and Design Support ....................... 16 Switching Characteristics ................................................7 Products ....................................................................16 Switching Waveforms ......................................................8 PSoC Solutions ......................................................... 16 Document Number: 001-45076 Rev. *F Page 2 of 16
