CY14B101KA-ZS45XI

Memory IC Overview

The CY14B101KA-ZS45XI is a non-volatile SRAM (nvSRAM) manufactured by Infineon Technologies. It features a storage capacity of 1 Mbit organized as 128K x 8 bits with an 8-bit data bus width. The device supports parallel interface access with a maximum access time of 45 ns. It operates within a supply voltage range of 2.7 V to 3.6 V and functions at temperatures between -40°C and +85°C. The component is housed in a 44-pin TSOP-II package.

Memory IC Feature Summary

• Combines SRAM speed with non-volatile data retention for seamless power-loss protection
• Eliminates the need for external battery backup circuits or complex write sequences
• Supports industrial temperature ranges for reliable operation in demanding environments

Memory IC Applications

• Industrial automation control systems requiring persistent configuration data
• Telecommunications equipment needing rapid state recovery after power interruption
• Medical devices storing critical calibration parameters without battery maintenance

Memory IC Procurement Notes

Verify current production status as this specific part number may be subject to discontinuation notices. Confirm package compatibility and lead times with authorized distributors. Ensure design-in includes appropriate decoupling capacitors for stable 3V operation. Check for end-of-life notifications prior to final procurement decisions.

Memory IC Selection Notes

Select this component when fast random access memory is required alongside non-vatility. Compare against standard SRAM plus EEPROM solutions for size and cost efficiency. Consider the 45 ns access speed relative to system clock requirements. Evaluate the TSOP-II footprint constraints against available PCB space.

Memory IC Part Context

This nvSRAM belongs to the CY14B101 family, offering 1 Mbit density. It serves as a drop-in replacement for volatile SRAM in applications where data loss during power cycles is unacceptable. The technology bridges the gap between fast volatile memory and slower non-volatile alternatives like Flash.

Memory IC Replacement Considerations

Check for direct pin-compatible substitutes within the CY14B101 series such as different speed grades or package options. Verify if newer generations from Infineon offer improved endurance or lower power consumption while maintaining functional equivalence.
