IDT7MPV6253

NOTES:
1. 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.

The IDT7MPV6253/55/56 modules belong to a family of secondary caches intended for use with PowerPC CPUbased systems. The IDT7MPV6253 uses IDT's 71V256 32K The IDT logo is a registered trademark of Integrated Device Technology, Inc. PowerPC is a trademark of IBM.

In addition, each of the modules uses the IDT 71216 16K x 15 Cache-Tag static RAM and IDT FCT logic. Extremely high speeds are achieved using IDT's high-reliability, low cost CMOS technology.

The low profile card edge package of IDT7MPV6253 allows 178 signal leads to be placed on a package 5.06" long, a maximum of 0.250" thick and a maximum of 1.08" tall. The module of IDT7MPV6253 space savings versus discrete components allows the OEM to design additional functions onto the system or to shrink the size of the motherboard for reduced cost.

All inputs and outputs are LVTTL-compatible, and operate from separate 5V (±5%) and 3.3V (+10/-5%) power supplies. Multiple GND pins of IDT7MPV6253 and on-board decoupling capacitors ensure maximum protection from noise.
