IS42S16160G-7BLI-TR

Product Overview

The IS42S16160G-7BLI-TR from ISSI, Integrated Silicon Solution Inc, is a 256Mbit SDRAM memory IC with a volatile DRAM format and a parallel interface. Its memory organization is 16M x 16, arranging the 256Mbit array as 16 million 16-bit words. The device operates from a 3V to 3.6V supply and supports a 143 MHz clock frequency with a 5.4 ns access time. It is packaged in a 54-TFBGA (8x8) surface-mount package, with an operating temperature range of -40°C to 85°C (TA). The parallel interface and 16-bit word organization connect the memory array to a system controller.

• Consumer electronic devices using a 3V to 3.6V surface-mount DRAM

Design & Procurement Notes

When selecting this device, map the 16M x 16 organization and parallel interface to the host controller address and data buses. The 143 MHz clock frequency and 5.4 ns access time require attention to timing closure and signal integrity. The 3V to 3.6V supply range and 54-TFBGA (8x8) surface-mount package affect the power rail, PCB land pattern, and thermal path. The -40°C to 85°C (TA) range defines the operating environment. Confirm controller compatibility with the parallel SDRAM interface and 143 MHz timing before integration.
