CY7C1328G-133AXIKJ

Memory IC Overview

The CY7C1328G-133AXIKJ is a high-speed synchronous static random-access memory (SRAM) integrated circuit manufactured by Cypress Semiconductor. It provides a total storage capacity of 4.5 Mbit, organized as 256K words by 18 bits. The device supports a maximum clock frequency of 133 MHz and features a fast access time of 4 ns. It utilizes a parallel memory interface for data transfer. The component is housed in a 100-pin Thin Quad Flat Package (TQFP) with dimensions of 14x20 mm.

Memory IC Feature Summary

• Supports synchronous pipelined architecture for high-speed data processing
• Provides 18-bit wide data bus configuration
• Operates at clock frequencies up to 133 MHz
• Features low latency with 4 ns access time

Memory IC Applications

• High-performance computing systems requiring fast buffer memory
• Network infrastructure equipment such as routers and switches
• Telecommunications base stations and signal processing units
• Industrial automation controllers needing rapid data logging

Memory IC Procurement Notes

Verify the specific suffix 'KJ' corresponds to the 100-TQFP package and lead-free RoHS compliance status. Confirm that the manufacturer designation aligns with current Infineon ownership structures post-acquisition. Ensure the part number matches the exact 133 MHz speed grade and 4 ns access time specifications required for your timing constraints before finalizing orders.

Memory IC Selection Notes

Select this component when a wide 18-bit data path is necessary for word-aligned applications. The synchronous nature makes it suitable for systems requiring precise clock-domain crossing. Compare against asynchronous alternatives if power consumption during idle states is a primary concern. Ensure the PCB layout accommodates the 100-pin TQFP footprint and thermal requirements associated with high-frequency operation.

Memory IC Part Context

This device belongs to the CY7C1328G family of synchronous SRAMs. It shares architectural similarities with the CY7C1328A series but offers improved performance metrics. The 'G' suffix typically denotes specific process technology enhancements over earlier generations. It serves as a direct replacement for older generation Cypress SRAMs in existing designs requiring upgraded speed capabilities.

Memory IC Replacement Considerations

The CY7C1328A-133AI is a documented equivalent within the same product family. Verify pin compatibility and electrical characteristics before substitution. Ensure the replacement part meets the same 133 MHz operational frequency and 4 ns access time requirements.
