47C04-E/P

Overview

The Microchip Technology 47C04-E/P is a static random access memory (SRAM) device with a storage capacity of 4 kbit, organized as 512 words by 8 bits. It features an I2C interface and operates within a supply voltage range of 4.5 V to 5.5 V. The component has a maximum clock frequency of 1 MHz and a maximum access time of 400 ns. It supports through-hole installation in a PDIP-8 package and functions across an extended temperature range from -40°C to +125°C.

Feature Summary

• Integrates non-volatile EEPROM functionality with volatile SRAM for data retention during power loss
• Utilizes standard I2C serial communication protocol for simplified system integration
• Designed for operation in extended industrial and automotive temperature environments

Applications

• Data logging systems requiring persistent storage
• Configuration memory for embedded controllers
• Industrial control units operating in harsh thermal conditions

Procurement Notes

Verify the specific suffix E/P confirms the extended temperature grade and PDIP-8 through-hole packaging. Confirm the manufacturer is Microchip Technology. Ensure the datasheet matches the 47C04 series specifications for 5V operation and I2C compatibility before procurement.

Selection Notes

Select this part when a low-pin-count serial memory solution is required for 5V logic systems. The PDIP-8 package suits prototyping or applications where surface mount technology is not feasible. Verify that the I2C bus speed requirements align with the 1 MHz maximum clock frequency specification.

Part Context

This component belongs to the 47C04 series of EERAM devices, which combine SRAM speed with EEPROM persistence. It serves as a compact, serial-accessible memory solution for microcontroller-based designs needing reliable data storage without complex external interfaces.

Replacement Considerations

Check for other suffixes such as /ST for surface mount variants or /I for industrial temperature grades within the same 47C04 family.
