Micron Technology, Inc. Memory MT48H4M16LFB4-8 IT

The MT48H4M16LFB4-8 IT is a 64Mbit mobile synchronous DRAM memory chip from Quarktwin Technology Ltd. It features a fully synchronous operation with all signals registered on the positive edge of the system clock, allowing for internal pipelined operation and the ability to change column addresses every clock cycle. The memory chip supports programmable burst lengths of 1, 2, 4, 8, or full page, and includes auto precharge and self-refresh modes, which can be standard or low power. This memory operates with a low voltage power supply of 1.8V for both VDD and VDDQ, and is compatible with LVTTL inputs and outputs. It has an extended operating temperature range of -25¬8C to +85¬8C and an industrial range of -40¬8C to +85¬8C. The device is packaged in a 54-ball FBGA format measuring 8mm x 8mm, and offers options for lead-free packaging. The timing specifications include a cycle time of 8ns at a clock frequency of 125 MHz with a CAS latency of 3. Engineers considering this memory chip should note its features for power-saving modes, including partial array self-refresh and deep power-down modes, which can be beneficial in mobile applications where power efficiency is critical.
