47L16-I/W16K

Overview

The Microchip Technology 47L16-I/W16K is a 16-kbit Static Random Access Memory (SRAM) device belonging to the 47L16 series. It operates within a supply voltage range of 2.7 V to 3.6 V and supports an industrial temperature range from -40°C to +85°C. The component utilizes an I2C interface with a maximum clock frequency of 1 MHz and features a memory organization of 2 k x 8 bits.

Feature Summary

• Integrates non-volatile EERAM technology for data retention without power
• Supports standard I2C serial communication protocols
• Designed for operation in industrial temperature environments

Applications

• Industrial sensor data logging
• Configuration storage in embedded systems
• Non-volatile parameter retention in low-power devices

Procurement Notes

Verify the specific suffix W16K against official Microchip documentation to confirm wafer-level packaging or special ordering requirements. Confirm RoHS compliance status through the manufacturer's datasheet. Ensure compatibility with existing I2C bus configurations before procurement.

Selection Notes

Select this component when non-volatile SRAM functionality is required within the 16-kbit capacity range. Verify that the 3.0 V nominal operating voltage aligns with the system power rails. Ensure the I2C interface speed requirements do not exceed the specified 1 MHz limit.

Part Context

This part belongs to the Microchip 47L16 family of EERAM devices, which combine the speed of SRAM with the non-volatility of EEPROM. These components are designed to replace traditional volatile memory solutions where data persistence is critical without the complexity of flash programming cycles.

Replacement Considerations

Consult official Microchip substitution guides for verified alternatives. Generic SRAM replacements may lack non-volatile retention capabilities.
