CY7C1371D-100AXIT

Memory IC Overview

The CY7C1371D-100AXIT is a 9-Mbit (256K x 36) synchronous flow-through SRAM manufactured by Infineon Technologies. It utilizes the No Bus Latency (NoBL) architecture to support unlimited true back-to-back read/write operations without wait states, transferring data on every clock cycle. The device operates at a maximum frequency of 100 MHz with an access time of 8.5 ns. It features registered inputs, byte write capability, and three chip enables for depth expansion. The component supports 3.3V/2.5V I/O power supplies and includes automatic power-down via ZZ mode or CE deselect.

Memory IC Feature Summary

• No Bus Latency (NoBL) architecture eliminates dead cycles between write and read cycles
• Registered inputs enable synchronous flow-through operation
• Byte Write capability allows selective data updates
• Automatic Power-down feature available using ZZ mode or CE deselect

Memory IC Applications

• Systems requiring frequent Write-Read transitions
• High-throughput data processing applications
• Back-to-back memory access scenarios

Memory IC Procurement Notes

Verify the specific suffix AXIT against official Infineon documentation to confirm package type and tape-and-reel configuration. Confirm RoHS compliance status and lead-free specifications directly from the current datasheet revision. Ensure the operating voltage range matches system requirements before procurement.

Memory IC Selection Notes

Select this component when zero-wait-state performance is critical for system throughput. The NoBL architecture is suitable for designs needing continuous data transfer without insertion of wait states. Verify pin compatibility if replacing ZBT devices. Consider the 100 TQFP package constraints for PCB layout.

Memory IC Part Context

This part belongs to the Cypress/Infineon Synchronous SRAM family featuring NoBL technology. It is functionally equivalent to ZBT devices but offers improved throughput through registered inputs and self-timed output buffers. The series supports both linear and interleaved burst orders for flexible memory interfacing.

Memory IC Replacement Considerations

The CY7C1371D is pin-compatible and functionally equivalent to ZBT devices. Verify specific substitute part numbers such as CY7C1371KV33 variants in official Infineon cross-reference lists.
