CY7C13451G-100BZXET

Memory IC Overview

The CY7C13451G-100BZXET is a 4-Mbit (128K × 36) synchronous flow-through static random-access memory manufactured by Infineon Technologies. It operates with a 3.3 V core supply and supports 2.5 V or 3.3 V I/O supplies. The device features an 8.0 ns maximum access time at a 100 MHz clock frequency, delivering high-performance 2-1-1-1 access rates. It utilizes a 165-ball FBGA package and includes user-selectable burst counter modes for Intel Pentium interleaved or linear burst sequences.

Memory IC Feature Summary

• Supports secondary cache applications with selectable linear or interleaved burst sequences via the MODE input pin.
• Integrates separate Processor Address Strobe (ADSP) and Controller Address Strobe (ADSC) inputs for flexible system interfacing.
• Features asynchronous output enable and ZZ sleep mode for power conservation while maintaining data integrity.
• Includes on-chip two-bit wrap-around burst counter that automatically increments addresses during burst accesses.

Memory IC Applications

• High-speed microprocessor secondary cache systems
• Systems requiring Intel Pentium compatible interleaved burst sequences
• Controller-based architectures utilizing dedicated address strobes

Memory IC Procurement Notes

Verify the specific suffix 'E' corresponds to automotive qualification grades if required by your application environment. Confirm the 'T' suffix indicates tape-and-reel packaging rather than tray distribution. Ensure the 165-ball FBGA footprint matches your PCB design constraints. Cross-reference the latest datasheet revision for any errata regarding the ZZ pin connection requirements.

Memory IC Selection Notes

Select this component when a 36-bit data width is necessary for processor interfaces. The dual voltage capability allows compatibility with both 2.5 V and 3.3 V I/O logic levels. The synchronous flow-through architecture minimizes glue logic requirements compared to asynchronous alternatives. Consider the 165-ball FBGA package size against available board space and thermal dissipation capabilities.

Memory IC Part Context

This part belongs to the Cypress/Infineon CY7C13451G family of 4-Mbit synchronous SRAMs. It shares architectural similarities with other members in the Standard Sync series but is distinct in its 128K x 36 organization. The device represents a transition from older Cypress designs now maintained under Infineon Technologies.

Memory IC Replacement Considerations

Publicly confirmed substitute part numbers are not provided in the source material. Verify compatibility with existing designs before considering alternative vendors or pin-compatible upgrades.

Memory IC FAQ

How is the burst sequence order determined?

The burst sequence is determined by the MODE input pin. A LOW selects a linear burst sequence, while a HIGH or floating state selects an interleaved burst sequence compatible with Intel Pentium processors.

What is the function of the ZZ pin?

The ZZ pin is an asynchronous input that places the device into a non-time critical sleep mode when asserted HIGH. Data integrity is preserved, and two clock cycles are required to enter or exit this mode.
