CY7C1325B-117BGC

Memory IC Overview

The CY7C1325B-117BGC is a 4.5-Mbit (256K x 18) synchronous static random-access memory (SRAM) device manufactured by Cypress Semiconductor Corp. It operates with a single 3.3V power supply and supports clock frequencies up to 117 MHz, featuring a 7 ns access time. The component utilizes a parallel interface and employs NoBL™ architecture for flow-through operation. It is housed in a 119-pin plastic ball grid array (PBGA) package measuring 14x22 mm.

Memory IC Feature Summary

• No Bus Latency (NoBL) architecture eliminates dead cycles between write and read operations.
• Flow-through operation allows data transfer on every clock cycle without wait states.
• Registered inputs support high-speed synchronous performance.
• Byte Write capability enables selective updating of data bytes.

Memory IC Applications

• High-performance cache memory systems
• Network routing and switching equipment
• Industrial control applications

Memory IC Procurement Notes

Verify the specific suffix BGC confirms the 119-PBGA package and 117 MHz speed grade against official datasheets. Confirm RoHS compliance status as older Cypress batches may differ. Ensure the supplier provides traceability documentation for this discontinued or legacy part number to guarantee authenticity and proper handling specifications.

Memory IC Selection Notes

Select this component when a 256K x 18 organization is required with synchronous flow-through performance. It serves as a pin-compatible alternative to ZBT devices while offering lower voltage operation at 3.3V. Consider the 119-ball BGA footprint for board space constraints and verify thermal requirements for the PBGA enclosure during design integration.

Memory IC Part Context

This device belongs to the CY7C1325 family of Synchronous SRAMs. It shares architectural similarities with other NoBL devices but is distinct in its 4.5-Mbit density and 18-bit word width. The BGC suffix specifically denotes the 119-ball BGA packaging option, differentiating it from TQFP or LQFP variants within the same electrical specification family.

Memory IC Replacement Considerations

Official substitutes include CY7C1325G-117BGC and CY7C1357B-100BGC. Verify pin compatibility and electrical parameters before substitution. Note that manufacturer transitions from Cypress to Infineon may affect long-term availability and documentation standards.
