47C16T-E/ST

Overview

The Microchip Technology 47C16T-E/ST is a 16 Kbit Electrically Erasable and Read-Only Memory (EERAM) integrated circuit. It features a memory organization of 2K x 8 bits and utilizes an I2C interface with a maximum clock frequency of 1 MHz. Designed for extended industrial temperature ranges, this component operates at a supply voltage of 5.0V. The device is housed in a TSSOP-8 surface-mount package and includes a word/page write cycle time of 1 ms.

Feature Summary

• Combines SRAM speed with EEPROM non-volatility using EERAM technology
• Supports standard I2C communication protocol for system integration
• Rated for extended industrial operating temperature conditions

Applications

• Industrial automation data logging
• Process automation control systems
• High-power module configuration storage

Procurement Notes

Verify the specific suffix 'E' confirms the extended industrial temperature rating and 'ST' denotes the TSSOP-8 package. Confirm the 5.0V operating voltage requirement matches the target circuit design. Ensure I2C bus compatibility with the host controller before procurement.

Selection Notes

Select this part when non-volatile storage with fast access speeds is required in harsh environments. The 16 Kbit capacity suits moderate data retention needs. Verify that the 1 MHz I2C speed meets system timing requirements and that the 5.0V supply aligns with available power rails.

Part Context

This component belongs to the 47C16 series of EERAM devices from Microchip Technology. These parts are designed to replace traditional EEPROMs where write endurance and speed are critical. The series offers a robust solution for applications requiring frequent data updates without the latency associated with conventional flash memory technologies.

Replacement Considerations

The 47C16-I/ST serves as a similar variant within the same family, differing primarily in the temperature grade designation.
