47C16-I/P

Overview

The Microchip Technology 47C16-I/P is a static random access memory component classified as EERAM, offering a storage capacity of 16 kbit. It features an organization of 2k x 8 and supports I2C interface communication with a maximum clock frequency of 1 MHz. The device operates within a supply voltage range of 2.7 V to 5.5 V and has a maximum power consumption of 400 uA. It is housed in a PDIP-8 package designed for through-hole mounting and functions reliably across an industrial temperature range from -40°C to +125°C.

Feature Summary

• Integrates EEPROM and SRAM technologies into a single non-volatile memory solution
• Utilizes standard I2C serial interface for simplified system connectivity
• Provides high endurance and data retention characteristics suitable for critical data logging

Applications

• Industrial control systems requiring persistent parameter storage
• Data logging applications in harsh environmental conditions
• Embedded systems needing reliable configuration data retention

Procurement Notes

Verify the specific suffix against official Microchip documentation to confirm package type and temperature grade. Ensure the I2C address matches your system design requirements. Confirm that the through-hole PDIP-8 package aligns with your PCB layout constraints. Cross-reference the datasheet revision date to ensure compatibility with current manufacturing standards.

Selection Notes

Select this component when non-volatile storage is required without the complexity of external flash controllers. The integrated architecture simplifies board design by combining volatile speed with non-volatile retention. Consider the I2C bus limitations and pin count if multiple devices are used on the same bus. Evaluate the operating voltage range against your system's power supply rails.

Part Context

This part belongs to the Microchip 47L/47C series of EERAM devices, which combine the benefits of EEPROM and SRAM. These components are designed to provide fast read/write speeds similar to SRAM while retaining data like EEPROM. The series is widely used in applications demanding high reliability and frequent data updates.

Replacement Considerations

Check for direct substitutes within the 47L04 or 47C04 series if lower capacity suffices. Verify pin-to-pin compatibility with other EERAM packages before substitution. Consult official Microchip change notices for any pinout or functional updates.
