NOTES:
1. Stresses greater than those listed under ABSOLUTE MAXIMUM RATINGS may cause permanent damage to the device.

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, IDT7MP4045 low profile package is ideal for systems with minimum board spacing while the SIMM configuration allows use of edge mounted sockets to secure the module.

All inputs and outputs of the IDT7MP4045/4145 are TTLcompatible and operate from a single 5V supply. Full asynchronous circuitry requires no clocks or refresh for operation and provides equal access and cycle times for ease of use. Identification pins are provided for applications in which different density versions of the module are used. In IDT7MP4045 way, the target system can read the respective levels of PD pins to determine a 256K depth.

The contact pins of IDT7MP4045 are plated with 100 micro-inches of nickel covered by 30 micro-inches minimum of selective gold.
