602-00032

Overview

The Parallax Inc. 602-00032 is a serial Electrically Erasable Programmable Read-Only Memory (EEPROM) integrated circuit designed for non-volatile data storage applications. This component features a storage capacity of 256 kilobits, organized as 32K x 8 bits, providing reliable retention of configuration parameters and user data without power. It utilizes an I2C bus interface for communication, supporting standard and fast mode operations with a maximum clock frequency of 400 kHz. The device operates within a supply voltage range of 1.8V to 5.5V, ensuring compatibility with various logic levels. Packaged in an 8-pin Dual Inline Package (DIP), it supports through-hole mounting and functions reliably across an industrial temperature range from -40°C to +85°C.

Feature Summary

• Provides non-volatile data storage with 256-kilobit capacity using electrically erasable technology
• Supports high-speed I2C serial communication with up to 400 kHz clock frequency
• Operates over a wide supply voltage range from 1.8V to 5.5V for broad system integration
• Designed for robust performance in industrial environments with extended temperature ratings

Applications

• Industrial control systems requiring persistent parameter storage
• Consumer electronics needing configuration memory
• Embedded devices utilizing I2C bus architectures
• Automotive instrumentation data logging

Procurement Notes

Verify the specific package variant and speed grade against the manufacturer's current datasheet before ordering. Confirm that the I2C address matches the target system design requirements. Ensure the operating voltage range aligns with the host microcontroller's logic levels. Check for any recent revisions to the RoHS compliance status or pinout definitions. Validate availability through authorized distributors to avoid counterfeit components.

Selection Notes

Select this component when a moderate storage density is required alongside simple serial connectivity. The I2C interface reduces pin count compared to parallel EEPROMs, saving board space. The wide voltage tolerance makes it suitable for mixed-signal designs. Consider the DIP package if prototyping or through-hole assembly is preferred over surface mount alternatives. Evaluate power consumption specifications if battery-operated applications are involved.

Part Context

This EEPROM belongs to Parallax Inc.'s broader memory portfolio, often paired with their Propeller microcontrollers and development boards. It serves as a companion storage solution for projects requiring persistent data retention beyond volatile RAM. The component is part of a series including variants like 602-00001 and 602-00013, differing primarily in storage capacity and organization while maintaining compatible interfaces.

Replacement Considerations

Direct substitutes include other 256K-bit I2C EEPROMs from manufacturers such as Microchip or STMicroelectronics. Verify pin compatibility and command set adherence before swapping. Alternative packages like SOIC or TSSOP may require adapter solutions if footprint changes are unacceptable.
