CY7C1440KV33-250BZXI

Memory IC Overview

The CY7C1440KV33-250BZXI is a 36-Mbit (1M × 36) pipelined synchronous SRAM manufactured by Infineon Technologies. It supports bus operations up to 250 MHz with a maximum clock-to-output time of 2.5 ns. The device utilizes a 3.3 V core power supply and accepts 2.5 V or 3.3 V I/O supplies. It features registered inputs and outputs for high-performance 3-1-1-1 access rates, user-selectable burst sequences, and separate processor and controller address strobes. The component is available in Pb-free 165-ball FBGA packages.

Memory IC Feature Summary

• Integrated on-chip error correction code (ECC) to reduce soft error rate
• Registered inputs and outputs enabling pipelined operation
• User-selectable burst counter supporting interleaved or linear burst sequences
• Synchronous self-timed writes with global write capability

Memory IC Applications

• Secondary cache systems utilizing linear burst sequences

Memory IC Procurement Notes

Verify the specific ordering suffix BZXI against official Infineon documentation to confirm package type and lead-free status. Confirm that the 250 MHz speed grade matches system timing requirements. Ensure voltage levels align with the specified 3.3 V core and 2.5 V/3.3 V I/O options before procurement.

Memory IC Selection Notes

Select this component when a 1M × 36 organization is required for pipelined synchronous SRAM applications. Consider the 250 MHz speed grade for high-frequency data processing needs. Verify compatibility with the 165-ball FBGA package constraints and ensure the design supports the necessary 3.3 V core and dual-voltage I/O requirements.

Memory IC FAQ

How does the device handle burst sequences?

The device provides a two-bit wraparound burst counter that implements either an interleaved or linear burst sequence, which is user-selectable via the MODE input.

What is the function of the ZZ pin?

The ZZ pin is an asynchronous sleep input. Asserting it HIGH places the SRAM in a power conservation sleep mode while preserving data integrity.
