27C256-17/J

Overview

The Microchip Technology 27C256-17/J is a CMOS electrically programmable read-only memory (EPROM) device. It provides a storage capacity of 256 kilobits, organized as 32K words by 8 bits. The component features a parallel interface and supports a maximum clock frequency of 5 MHz. It operates within a voltage range of 4.5 V to 5.5 V. The package type is LCC-32. The access time is specified at 170 ns. The data retention period is documented as exceeding 200 years.

Feature Summary

CMOS technology for low power consumption
High-speed performance with fast access times
Separate chip enable and output enable controls
Auto ID aids automated programming

Applications

Industrial systems requiring reduced power consumption
Reliable embedded memory solutions
Automated programming environments

Procurement Notes

Verify the specific suffix J indicates industrial temperature range compliance (-40°C to +85°C). Confirm package details match LCC-32 requirements. Check export restrictions if applicable. Ensure programming equipment supports the high-speed express algorithm. Validate RoHS status against project specifications.

Selection Notes

Select this part for applications needing non-volatile storage with high reliability. Consider the 170 ns access speed for system timing constraints. Evaluate the LCC-32 package for surface mount compatibility. Compare power consumption metrics against other EPROM options. Verify voltage supply stability within the 4.5 V to 5.5 V range.

Part Context

This component belongs to the 27C256 series of 256K-bit EPROMs from Microchip Technology. It shares architectural similarities with other devices in the family, such as the AT27C256R. The series is designed for general-purpose memory applications where data retention and low standby current are critical factors for long-term system operation.
