Features

  • Wide voltage range: 2.7V–3.6V
  • Access Time: 55 ns, 70 ns
  • Ultra-low active power — Typical active current: 1mA @ f = 1 MHz — Typical active current: 14 mA @ f = fmax (For 55-ns) —Typical active current: 8 mA @ f = fmax (For 70-ns)
  • Ultra low standby power
  • Automatic power-down when deselected
  • CMOS for optimum speed/power Functional Description The M24L216128SA is a high-performance CMOS Pseudo Static RAM organized as 128K words by 16 bits that supports an asynchronous memory interf ace. This device features advanced circuit design to provide ultra-low active current. This is ideal for portable applications such as cellular telephones. The device can be put into standby mode when deselected ( CE HIGH or both BHE and BLE are HIGH). The input/output pins (I/O 0 through I/O 15) are placed in a high-impedance state when the chip is deselected ( CE HIGH), or when the outputs are disabled ( OE HIGH), or when both Byte High Enable and Byte Low Enable are disabled ( BHE , BLE HIGH), or during a write operation ( CE LOW and WE LOW). Writing to the device is accomplished by asserting Chip Enable ( CE LOW) and Write Enable ( WE ) input LOW. If Byte Low Enable (BLE ) is LOW, then data from I/O pins (I/O0 through I/O 7), is written into the location specified on the address pins (A0 through A16). If Byte High Enable ( BHE ) is LOW, then data from I/O pins (I/O 8 through I/O 15) is written into the location specified on the address pins (A 0 through A16). Reading from the device is accomplished by asserting Chip Enable ( CE LOW) 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 will appear on I/O 0 to I/O 7. If Byte High Enable( BHE ) is LOW, then data from memory will appear on I/O8 to I/O15. Refer to the truth table for a complete description of read and write modes. Logic Block Diagram

Test conditions for all parameters other than tri-state para meters assume signal transition time of 1 ns/V, timing referenc e levels of VCC(typ)/2, input pulse levels of 0V to V CC(typ.), and output loading of the specified IOL/IOH as shown in the “AC Test Loads and Waveforms” section. 11. t HZOE, tHZCE, tHZBE, and tHZWE transitions are measured when the outputs ente r a high impedance state.12.The internal Write time of the memory is defined by the overlap of WE , CE = V IL, BHE and/or BLE = V IL. All signals must be ACTIVE to initiate a write and any of these signals can terminate a writ e by going INACTIVE. The data input set-up and hold timing should be referenced to the edge of the signal that terminates the write. 13. High-Z and Low-Z parameters are characterized and are not 100% tested. 14. To achieve 55-ns performance, the read access should be CE controlled. In this case t ACE is the critical parameter and tSK is satisfied when the addresses are stable prior to chip enab le going active. For the 70-ns cycle, the addresses must be stable within 10 ns after the start of the read cycle.
