Additional Details

The MT48LC16M16A2TG-7EIT SDRAM is specifically designed to meet the demands of applications operating in extreme temperature conditions. Its 16M x 16 organization provides a good balance between memory density and cost. The 143 MHz operating frequency (implied by the -7E speed grade) allows for high-speed data transfers, making it suitable for real-time applications. The programmable burst length feature allows optimization of data transfer based on specific system requirements. The auto-refresh feature maintains data integrity by automatically refreshing the memory cells, while the self-refresh mode minimizes power consumption when the system is idle. The four internal banks allow for interleaved memory access, improving overall system performance. The extended temperature range makes it well-suited for industrial and automotive applications where reliable operation in extreme conditions is critical. This SDRAM provides a robust and reliable memory solution for demanding environments.
