Memory IC datasheet and documents for AT28C64X-15SI

AT28C64X-15SI

Memory IC Overview

The AT28C64X-15SI is a 64K (8K x 8) parallel EEPROM manufactured by Microchip Technology. It features a 150 ns access time and operates on a single 5V ± 10% power supply. The device utilizes CMOS technology, drawing 30 mA active current and less than 100 µA in standby mode. It supports byte write operations with internal address and data latches, offering end-of-write detection via DATA polling. The component is housed in a 28-lead SOIC package and is rated for industrial temperature ranges from -40°C to +85°C.

Memory IC Feature Summary

Self-timed byte write cycle with automatic clear before write
DATA polling capability for detecting write completion
CMOS and TTL compatible inputs and outputs
High reliability with extended endurance and data retention

Memory IC Applications

Nonvolatile data storage in embedded systems
Configuration memory for microprocessors
Device identification and tracking applications

Memory IC Procurement Notes

Verify the specific ordering suffix against official Microchip documentation to confirm package type and temperature range. Confirm that the 'X' designation aligns with the intended RDY/BUSY pin configuration, as this variant does not include the ready/busy output found in standard versions. Ensure compatibility with existing board layouts regarding the 28-lead SOIC footprint.

Memory IC Selection Notes

Select this component when a 150 ns access speed is required for 64K nonvolatile storage within an industrial environment. The absence of the RDY/BUSY pin distinguishes it from the standard AT28C64, necessitating reliance on DATA polling for write cycle monitoring. Consider the low standby current and high endurance specifications for long-term deployment scenarios.

Memory IC Part Context

This part belongs to the AT28C64 family of parallel EEPROMs produced by Microchip Technology. The series provides various access speeds and packaging options to suit different system requirements. The 'X' suffix indicates a specific pinout variation where the RDY/BUSY function is omitted, differing from the base AT28C64 model which includes this feature.
