*Stresses greater than those listed under "Absolute Maximum Ratings" may cause permanent damage to the device. This is a stress rating only, and functional operation of the device at these or any other conditions above those indicated in the operational sections of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect reliability.
**Maximum junction temperature depends upon package type, cycle time, loading, ambient temperature and airflow. See Micron Technical Note TN-05-14 for more information.
DescriptionThe Micron® SyncBurst™ SRAM family MT58L128L32D1 employs high-speed, low-power CMOS designs that are fabricated using an advanced CMOS process.
Micron's 4Mb SyncBurst SRAMs MT58L128L32D1 integrate a 256K x 18, 128K x 32, or 128K x 36 SRAM core with advanced synchronous peripheral circuitry and a 2-bit burst counter. All synchronous inputs pass through registers controlled by a positive-edge-triggered single clock input (CLK). The synchronous inputs of MT58L128L32D1 include all addresses, all data inputs, active LOW chip enable (CE#), two additional chip enables for easy depth expansion (CE2, CE2#), burst control inputs (ADSC#, ADSP#, ADV#), byte write enables (BWx#) and global write (GW#).
