IS43R16160B-6TL

Memory IC Overview

The IS43R16160B-6TL is a 256Mb DDR SDRAM manufactured by ISSI. It features a 16-bit data bus width and an organization of 16M x 16 across four banks. The component supports a maximum clock frequency of 167 MHz with a CAS latency of 3 or 2.5, and an access time of 6 ns. It operates within a voltage range of 2.3V to 2.7V and functions in commercial temperatures from 0°C to +70°C. The device utilizes a 66-pin TSOP II package.

Memory IC Feature Summary

• Double data rate architecture enabling two data transfers per clock cycle
• Four-bank operation controlled by bank address pins for row hiding
• SSTL_2 interface with differential clock input and DLL alignment
• Programmable burst length and type via mode register settings

Memory IC Applications

• General purpose memory systems requiring high-speed data transfer
• Embedded applications utilizing synchronous DRAM interfaces
• Consumer electronics supporting DDR SDRAM standards

Memory IC Procurement Notes

Verify the specific suffix '6TL' against the manufacturer's current datasheet to confirm pinout and electrical characteristics match your design requirements. Ensure compatibility with SSTL_2 signaling levels and verify that the 66-pin TSOP II package dimensions fit your PCB layout constraints before finalizing orders.

Memory IC Selection Notes

Select this component when a 256Mb capacity with a 16-bit interface is required. The -6 speed grade provides 167 MHz performance suitable for standard DDR applications. Consider the commercial temperature range limits and ensure the system power supply can maintain stability between 2.3V and 2.7V during all operational states.

Memory IC Part Context
