47C04-I/P

Overview

The Microchip Technology 47C04-I/P is a 4 kbit Static Random Access Memory (SRAM) device categorized as an EERAM, combining SRAM speed with EEPROM non-volatility. It features a 512 x 8 organization and communicates via an I2C interface with a maximum clock frequency of 1 MHz. The component operates within a supply voltage range of 4.5 V to 5.5 V and supports through-hole mounting in a PDIP-8 package. It ensures data retention for up to 200 years and functions reliably across an industrial temperature range from -40°C to +125°C.

Feature Summary

• Integrates static RAM performance with non-volatile storage capabilities to eliminate the need for external battery backup circuits.
• Utilizes a standard two-wire I2C serial interface for simplified system integration and reduced pin count requirements.
• Provides extended industrial temperature operation suitable for demanding environmental conditions without compromising data integrity.

Applications

• Industrial control systems requiring persistent configuration storage
• Embedded devices needing fast access to non-volatile parameters
• Automotive electronics operating under strict thermal constraints

Procurement Notes

Verify the specific suffix designation against official Microchip documentation to confirm package type and temperature grade. Ensure compatibility with existing PCB footprints for the PDIP-8 through-hole configuration. Confirm that the I2C address settings align with system bus requirements before finalizing procurement orders.

Selection Notes

Select this component when high-speed random access is required alongside permanent data retention in a low-pin-count package. The 4.5 V to 5.5 V operating range makes it suitable for standard 5 V logic systems. Consider the PDIP-8 form factor if prototyping or applications necessitate through-hole assembly methods over surface mount alternatives.

Part Context

This part belongs to the 47C04 series of serial EERAMs manufactured by Microchip Technology. The series combines the speed of SRAM with the non-volatility of EEPROM. The 'I' suffix indicates an industrial temperature rating, while '/P' denotes the PDIP-8 package style. This family is designed for applications requiring frequent data updates without the wear-out limitations of traditional flash memory.

Replacement Considerations
