IS61LP6432A-133TQLI-TR

Memory IC Overview

The IS61LP6432A-133TQLI-TR is a 2 Mbit synchronous static random access memory (SRAM) organized as 64K words by 32 bits. Manufactured by ISSI, this component operates with a maximum clock frequency of 133 MHz and features a 4 ns access time. It utilizes a parallel interface and functions within a supply voltage range of 3.135 V to 3.6 V. The device supports Single Data Rate (SDR) data transfer modes and is housed in a 100-pin LQFP package measuring 14x20 mm. It is designed for surface mount installation and operates reliably across an extended temperature range from -40°C to +85°C.

Memory IC Procurement Notes

Verify the specific suffix 'TR' against official ISSI documentation to confirm tape-and-reel packaging status, as distributor listings may vary. Confirm RoHS compliance details directly with the manufacturer or authorized channels. Ensure the ordering part number matches the exact speed grade and package variant required for your design. Cross-reference the datasheet revision date to ensure all electrical characteristics align with current specifications before finalizing procurement.

Memory IC Selection Notes

Select this component when a 2 Mbit capacity with 32-bit width is required for synchronous applications. The 133 MHz speed grade suits designs needing moderate-to-high bandwidth without excessive power consumption. Consider the 100-pin LQFP footprint for PCB layout constraints. Verify that the 3.3V I/O logic levels match the system's processor or controller interface requirements. Evaluate thermal management needs given the operational temperature range and power dissipation characteristics.

Memory IC Part Context

This part belongs to the IS61LP6432A family of synchronous SRAMs from ISSI. It shares architectural similarities with other members like the IS61LP6436A series but differs in data width organization. The 'LQFP' designation indicates the leaded quad flat package type, distinct from TQFP or BGA variants found in other product lines. This specific model represents a standard offering for general-purpose high-speed memory applications within the ISSI portfolio.

Memory IC Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Consult ISSI technical support or authorized distributors for qualified alternatives. Ensure any replacement maintains identical pinout, voltage levels, and timing parameters to guarantee compatibility.
