X1286V14IT1

Overview

The X1286V14IT1 is a non-volatile memory component manufactured by Renesas Electronics Corporation, belonging to the X1286 series. It features an SPI serial interface and is housed in a 14-TSSOP surface-mount package. The device operates within a supply voltage range of 2.7V to 5.5V and supports industrial temperature conditions from -40°C to +85°C. Key electrical characteristics include a typical access time of 70ns and a maximum active current of 40mA with standby current limited to 200μA. The memory architecture provides byte-alterable capabilities without requiring external high voltages or complex programming algorithms.

Feature Summary

• SPI Serial Interface for simplified system integration
• Non-Volatile Memory with 100-year data retention
• Single 5V Supply Operation (2.7V to 5.5V range)
• Self-timed Write Cycle with Page Write Support

Applications

• Industrial automation control systems
• Consumer electronics configuration storage
• Embedded systems requiring persistent parameter storage

Procurement Notes

Verify RoHS compliance status as historical records indicate potential non-compliance for specific manufacturing lots. Confirm end-of-life status and last-time-buy availability through authorized distributors. Ensure the selected package variant matches the 14-TSSOP footprint requirements for PCB layout compatibility.

Selection Notes

Select this component when a small-footprint, serial EEPROM is required for low-volume data logging or configuration storage. Compare against parallel EEPROMs if higher throughput is needed, or flash memory if larger block sizes are necessary. Verify that the 70ns access time meets the system clock speed requirements.

Part Context

This part belongs to the X1286 family of serial EEPROMs designed for cost-sensitive applications. It utilizes CMOS floating gate technology similar to other Intersil/Renesas memory products. The 14-TSSOP package offers a compact solution for space-constrained designs compared to traditional PLCC or SOIC packages.

Replacement Considerations

Check for direct pin-compatible replacements within the X1286 series with different resistance or speed grades. Verify functional equivalence with other SPI EEPROMs from vendors like Microchip or STMicroelectronics, ensuring voltage levels and command sets align.
