602-20011

Overview

The Parallax Inc. 602-20011 is a serial EEPROM memory device designed for surface-mount applications, specifically identified as the BASIC Stamp 1 SMT variant. It features a storage capacity of 4 Kbit (512 bytes) organized in a 512 x 8 configuration. The component utilizes an SPI interface with a maximum clock frequency of 2 MHz. It operates within a supply voltage range of 2.7 V to 5.5 V and is housed in an 8-SOIC package.

Feature Summary

• Supports high-speed serial data transfer via SPI protocol
• Designed for compact surface-mount integration
• Compatible with BASIC Stamp 1 microcontroller environments

Applications

• Embedded data logging systems
• Configuration parameter storage for microcontrollers
• Non-volatile memory expansion for embedded devices

Procurement Notes

Verify current availability status as distribution may be limited. Confirm package type matches design requirements. Ensure voltage levels align with system specifications. Check for end-of-life status or obsolescence notices from the manufacturer before finalizing procurement plans.

Selection Notes

Select this component when a small, non-volatile memory solution is required for BASIC Stamp 1 projects. The SPI interface offers faster communication compared to I2C alternatives. Consider the 8-SOIC package constraints for PCB layout. Verify power supply stability within the specified operating range.

Part Context

This part belongs to Parallax's line of EEPROM memories tailored for their BASIC Stamp series. It serves as a dedicated storage solution for the BASIC Stamp 1 platform, providing reliable data retention in a compact form factor suitable for portable and embedded applications.

Replacement Considerations

Direct substitutes include other 4K-bit SPI EEPROMs in SOIC-8 packages. Verify pin compatibility and voltage tolerance. Alternative Parallax parts like 602-20032 offer higher capacity but may require interface adjustments.
