CY7C0852AV-133AXI

Memory IC Overview

The CY7C0852AV-133AXI is a 4.5 Mbit (128K x 36) Synchronous Static Random Access Memory manufactured by Infineon Technologies, formerly Cypress Semiconductor. It operates at a maximum clock frequency of 133 MHz with an access time of 4 ns. The device utilizes a parallel interface and functions as volatile memory. It supports Single Data Rate (SDR) data transfer modes. The component is designed for surface mount installation in a TQFP-176 package. It requires a supply voltage between 3.135 V and 3.465 V, with a maximum power consumption of 300 mA. The operating temperature range spans from -40°C to +85°C.

Memory IC Feature Summary

• Synchronous operation with registered control, address, and data lines for minimal setup and hold times
• Internal self-timed write pulse width independent of R/W signal duration
• Burst counter on input address register allows internal address incrementing after external loading
• Power-down capability via chip enable signals to reduce static power consumption

Memory IC Applications

• High-speed data buffering in telecommunications systems
• Cache memory applications in embedded processing architectures
• Network switching equipment requiring low-latency data storage
• Industrial control systems utilizing synchronous logic interfaces

Memory IC Procurement Notes

Verify current availability status as the component may be subject to end-of-life restrictions or limited distribution channels. Confirm that the TQFP-176 package matches the target PCB footprint requirements. Ensure the 3.3V supply rail stability meets the specified voltage tolerance limits during operation. Check for moisture sensitivity classification compliance if the component has been stored in non-controlled environments prior to assembly.

Memory IC Selection Notes

Select this component when a 128K x 36 word organization is required for synchronous memory applications. The 133 MHz speed grade suits designs needing high throughput with single data rate transfers. Consider the TQFP-176 package constraints for board space limitations. Evaluate the 300 mA maximum current draw against the system's power budget capabilities. Verify compatibility with existing synchronous bus protocols before integration into the design architecture.

Memory IC Part Context

This part belongs to the Flex36 family of 3.3V synchronous dual-port RAMs, offering pipelined architecture for high-speed performance. The series includes various densities such as 1M, 2M, and 9M configurations. The CY7C0852AV specifically provides a 4.5 Mbit capacity optimized for wide-data-path applications. It represents a transition period product from Cypress Semiconductor to Infineon Technologies.

Memory IC Replacement Considerations

Check for direct pin-compatible substitutes within the same Flex36 family, such as the CY7C0851AV or CY7C0853AV, depending on specific feature requirements. Verify electrical parameter equivalence for any alternative sourcing options.
