CY7C1383B-100BZI

Memory IC Overview

The CY7C1383B-100BZI is a 9-Mbit (256K x 36/512K x 18) Synchronous Flow-Through SRAM manufactured by Cypress Semiconductor. It operates with a 3.3V core supply and supports 2.5V or 3.3V I/O levels. The device features a synchronous architecture with registered inputs, enabling flow-through operation without wait states. It includes a user-selectable burst counter for Intel Pentium interleaved or linear sequences and offers fast clock-to-output access times of 8.5 ns for the 100-MHz version.

Memory IC Feature Summary

• Synchronous flow-through architecture eliminates dead cycles between write and read operations
• User-selectable burst counter supporting Intel Pentium interleaved or linear burst sequences
• Registered inputs enable continuous data transfer on every clock cycle
• Asynchronous output enable allows flexible control of data bus driving

Memory IC Applications

• High-speed microprocessor cache memory interfaces
• Network router and switch buffering systems
• Industrial automation controller memory modules

Memory IC Procurement Notes

Verify the specific suffix BZI to confirm the package type and temperature range against the official datasheet. Ensure voltage requirements match the system design, as the device supports both 2.5V and 3.3V I/O supplies. Confirm availability status directly with authorized distributors, as lead times may vary based on production schedules and regional stock levels.

Memory IC Selection Notes

Select this component when a synchronous flow-through interface is required to minimize glue logic in high-performance designs. Consider the 256K x 36 organization for wide data paths or the 512K x 18 configuration for standard widths. Verify that the 100-MHz speed grade meets the system clock requirements and that the operating temperature range aligns with the environmental conditions of the target application.

Memory IC Part Context

This part belongs to the CY7C13xxB family of Synchronous Flow-Through SRAMs from Cypress. These devices are designed to replace asynchronous static RAMs in high-speed applications by providing zero-wait-state performance. The family typically includes variants with different densities and speed grades, all sharing similar pinouts and functional characteristics to facilitate easy upgrades.

Memory IC Replacement Considerations

Check for direct pin-compatible alternatives within the same Cypress family, such as the CY7C1363B series, which shares similar architectural features. Ensure any substitute maintains the synchronous flow-through capability and compatible voltage levels to avoid redesigning the interface logic.
