DESCRIPTION:
The IDT7MP4045/4145 is a 256K x 32 static RAM module constructed on an epoxy laminate (FR-4) substrate using 8 256K x 4 static RAMs in plastic SOJ packages. Availability of four chip select lines (one for each group of two RAMs) provides byte access. The IDT7MP4045 is available with access time as fast as 10ns with minimal power consumption. The IDT7MP4045 is packaged in a 64 pin FR-4 ZIP (Zigzag In-line vertical Package)or a 64 pin SIMM (Single In-line Memory Module) where as the 7MP4145 is packaged in a 72 pin SIMM (Single In-line Memory Module). The 4045 ZIP configuration allows 64 pins to be placed on a package 3.65 inches long and 0.365 inches wide. The 7MP4045 ZIP is only 0.585 inches high, this low profile package is ideal for systems with minimum board spacing while the SIMM configuration allows use of edge mounted sockets to se...
