AS6C4008-55SINTR

Memory IC Overview

The AS6C4008-55SINTR is a 4 Mbit (512K x 8) asynchronous static random-access memory manufactured by Alliance Memory. It operates within a voltage range of 2.7 V to 5.5 V and features a maximum access time of 55 ns. The device utilizes a parallel interface and is housed in a 32-pin Thin Shrink Small Outline Package (TSOP). Designed for industrial applications, it supports a minimum operating temperature of -40°C and a maximum of +85°C. The component draws a maximum supply current of 60 mA and includes moisture sensitivity classification.

Memory IC Procurement Notes

Verify the specific suffix 'IN' against the manufacturer's official datasheet to confirm lead-free status and RoHS compliance details. Ensure the TSOP-32 package dimensions match the target PCB footprint requirements. Confirm that the 55 ns speed grade aligns with the system timing constraints before finalizing procurement.

Memory IC Selection Notes

Select this component when a high-density 4 Mbit SRAM solution is required for designs supporting both 3.3 V and 5 V logic levels. The TSOP-32 surface-mount package facilitates automated assembly processes. Verify that the 60 mA active current consumption fits within the power budget of the host system.

Memory IC Part Context

This part belongs to the AS6C4008 series of asynchronous SRAMs. It provides non-volatile-like retention characteristics without the complexity of flash programming cycles. The 512K x 8 organization offers a balance between density and pin count for general-purpose memory applications.

Memory IC Replacement Considerations

Cross-reference with other manufacturers offering 512K x 8 asynchronous SRAMs in TSOP-32 packages. Verify pinout compatibility and electrical specifications such as access time and voltage ranges before substituting.
