EMC643SP16CKDT-70LF-SU

Memory IC Overview

The EMC643SP16CKDT-70LF-SU is a 64Mbit (4 Meg x 16 bit) CellularRAM device featuring a multiplexed address/data bus. It supports both asynchronous and burst operations with random access times of 70ns. The device operates on VCC and VCCQ supplies ranging from 1.7V to 1.95V. Burst mode supports clock rates up to 133MHz with variable or fixed initial latencies. Low-power features include temperature compensated self refresh, partial array refresh, and deep power-down modes. The component is housed in a 49-ball FBGA package.

Memory IC Feature Summary

Multiplexed address/data bus reduces signal count while maintaining high bandwidth
Supports seamless burst operation with transparent self-refresh mechanism
Configurable low-power modes including deep power-down and partial array refresh
On-chip voltage sensor for automatic power-up initialization

Memory IC Applications

Low-power portable applications
Wireless devices requiring pseudo-static RAM alternatives
Systems needing high-speed synchronous burst transfers

Memory IC Procurement Notes

Verify the specific suffix 'DT' corresponds to the 49-ball FBGA package configuration as listed in the ordering information table. Confirm that the industrial temperature range variant is required if operating conditions extend below -30°C, as the standard SU suffix denotes wireless range. Ensure supply voltages remain within the 1.7V to 1.95V specification during procurement validation.

Memory IC Selection Notes

Select this component when a high-density alternative to SRAM is needed for portable systems. It is suitable for designs requiring a multiplexed interface to minimize pin counts. Consider the 133MHz burst capability for high-bandwidth requirements. Verify that the system controller supports the CellularRAM control signals such as ADV# and WAIT for proper synchronization.

Memory IC Part Context

This part belongs to the EMC643SP16CKx-SU family of 64M CellularRAM products developed by Jeju Semiconductor Corporation. These devices are CMOS pseudo-static random access memories designed for low-power applications. The family includes variations in packaging and temperature ranges, sharing the same core DRAM architecture and interface specifications.
