CYM1851V33

851V33 PRELIMINARY CYM1851V33 1,024K x 32 3.3V Static RAM Module Features High-density 3.3V 32-megabit SRAM module 32-bit Standard Footprint supports densities from 16K x 32 through 1M x 32 High-speed SRAMs — Access time of 12 ns Low active power — 3.3W (max.) at 12 ns 72 pins Available in ZIP, SIMM, or angled SIMM format Functional Description The CYM1851V33 is a 3.3V high-performance 32-megabit static RAM module organized as 1,024K words by 32 bits. This module is constructed from eight 1,024K x 4 SRAMs in SOJ packages mounted on an epoxy laminate substrate. Four chip selects are used to independently enable the four bytes. Reading or writing can be executed on individual bytes or any combination of multiple bytes through proper use of selects. The CYM1851V33 is designed for use with standard 72-pin SIMM sockets. The pinout is downward compatible with the 64-pin JEDEC ZIP/SIMM module family (CYM1821, CYM1831, CYM1836, and CYM1841). Thus, a single moth...
