Overview
The Microchip Technology 47L04T-E/ST is a 4-kbit synchronous EERAM device organized as 512k words by 8 bits. It operates with an I2C interface and supports a maximum clock frequency of 1 MHz. The component functions within a supply voltage range of 2.7 V to 3.6 V, drawing a maximum power current of 400 uA. It features a 400 ns access time and is rated for industrial temperature operation from -40°C to +85°C. The device utilizes a TSSOP-8 surface-mount package.
Feature Summary
- Combines SRAM speed with EEPROM non-volatility through synchronous EERAM technology
- Supports standard I2C communication protocol for system integration
- Provides low-power operation suitable for battery-constrained applications
Applications
- Data logging in industrial monitoring systems
- Configuration storage in embedded controllers
- Parameter retention in portable electronic devices
Procurement Notes
Verify the specific suffix 'T' indicates tape-and-reel packaging when ordering. Confirm the '-E' designation aligns with the required industrial temperature range specifications. Ensure the I2C address configuration matches the target system design requirements before finalizing procurement.
Selection Notes
Select this component for designs requiring fast random access memory performance with non-volatile data retention. The synchronous I2C interface simplifies timing constraints compared to asynchronous alternatives. Consider the TSSOP-8 package dimensions for PCB layout compatibility and thermal management needs.
Part Context
This part belongs to the Microchip 47L04 series of synchronous EERAMs. It serves as a bridge between volatile SRAM and traditional EEPROM technologies. The series offers high endurance and instant write capabilities without page programming delays typical of flash memory solutions.
Replacement Considerations
Consult official Microchip documentation for verified cross-reference part numbers. Verify pinout compatibility and electrical parameter alignment before substituting any alternative components.
