47C16T-I/SN

Overview

The Microchip 47C16T-I/SN is a 16Kbit SRAM memory IC with EEPROM backup, organized as 2048 x 8 bits. It features an I2C interface with a clock frequency of 1 MHz and access time of 400 ns. The device operates on a supply voltage range of 4.5 V to 5.5 V with a maximum supply current of 400 uA. It is housed in an 8-pin SOIC package and supports industrial temperature ranges from -40°C to +85°C.

Feature Summary

• Combines SRAM speed with EEPROM non-volatility for data retention without battery support
• Utilizes standard I2C serial interface for simplified system integration
• Operates within wide industrial temperature specifications

Applications

• Data logging systems requiring persistent storage
• Industrial control units needing configuration retention
• Embedded sensors maintaining calibration data

Procurement Notes

Verify the exact suffix against official Microchip documentation to confirm package type and temperature grade. Ensure compatibility with I2C bus voltage levels before integration. Confirm availability through authorized distributors as lead times may vary. Check for specific ordering prefixes if tape and reel quantities are required for automated assembly processes.

Selection Notes

Select this component when non-volatile storage is needed without external batteries. The I2C interface reduces pin count compared to parallel alternatives. Verify that the 1 MHz clock speed meets system timing requirements. Consider the 8-pin SOIC package constraints for PCB layout space and thermal management needs during selection.

Part Context

This part belongs to Microchip's EERAM family, integrating SRAM and EEPROM on a single die. It eliminates the need for separate non-volatile memory chips and backup power circuits. The series offers various organization sizes and package options to suit different embedded memory applications efficiently.

Replacement Considerations

Check for 47C16T-E/SN for extended temperature variants. Verify 47C16-I/SN for potential pin-compatible alternatives without EEPROM backup. Consult official substitution guides for any functional differences in interface protocols or voltage tolerances.
