IS46R16160D-6TLA1

Memory IC Overview

The IS46R16160D-6TLA1 is a 256-Mbit DDR SDRAM manufactured by ISSI. It features a 16M x 16 organization and operates at a maximum clock frequency of 167 MHz (Speed Grade -6). The device utilizes a 2.5V ± 0.2V power supply with SSTL_2 compatible I/Os. It is housed in a 66-pin TSOP-II package and supports an automotive temperature range of -40°C to +85°C.

Memory IC Feature Summary

• Double-data rate architecture enabling two data transfers per clock cycle
• Four internal banks for concurrent operations
• Supports programmable CAS latency, burst length, and burst type
• Includes Auto Refresh and Self Refresh modes

Memory IC Applications

• Automotive electronic systems
• Network and communication equipment
• Consumer electronics requiring high-speed memory

Memory IC Procurement Notes

Verify the specific speed grade (-6) and package configuration (66-pin TSOP-II) against system requirements. Confirm that the automotive temperature rating (-40°C to +85°C) aligns with the operational environment. Ensure compatibility with SSTL_2 signaling standards and 2.5V power supplies during integration.

Memory IC Selection Notes

Select this component when a 256-Mbit density with a 16-bit interface is required. The -6 speed grade provides up to 167 MHz operation. Consider the 66-pin TSOP-II package for board space constraints. Verify that the controller supports DDR SDRAM initialization sequences and SSTL_2 termination requirements.

Memory IC Part Context

This part belongs to the IS43/46R16160D series of 256-Mbit DDR SDRAMs from ISSI. The 'IS46' prefix typically denotes automotive-grade variants, while 'D' indicates the specific speed bin. The suffix '6TLA1' specifies the -6 speed grade, TSOP-II package, lead-free composition, and automotive temperature range.

Memory IC Replacement Considerations

Direct replacements within the same family include other speed grades like IS46R16160D-5TLA1 or different package options such as the 60-ball BGA variant IS46R16160D-6BLA1. Ensure pinout and electrical characteristics match before substitution.
