AT27C512R-15RC

Memory IC Overview

The AT27C512R-15RC is a 524,288-bit (64K x 8) one-time programmable read-only memory manufactured by Microchip Technology. It operates on a single 5V ±10% supply and features a maximum access time of 150 ns. The device utilizes high-reliability CMOS technology with low power consumption, drawing a maximum of 20 mA in active mode and 100 μA in standby. It is housed in a 28-lead SOIC package and supports commercial temperature ranges from 0°C to 70°C.

Memory IC Feature Summary

• Supports Rapid Programming Algorithm for efficient byte programming
• Includes integrated product identification code for manufacturer verification
• Features CMOS and TTL compatible inputs and outputs
• Provides hardware and software data protection via write protect pin

Memory IC Applications

• Firmware storage in microprocessor systems
• Industrial control applications
• Commercial embedded systems
• Automotive electronics requiring specific temperature grades

Memory IC Procurement Notes

Verify the ordering suffix RC corresponds to the 28-lead Plastic Gull Wing Small Outline (SOIC) package configuration. Confirm the temperature range designation matches the required operational environment, as suffixes indicate Commercial, Industrial, or Automotive ratings. Ensure compatibility with standard JEDEC packages for PCB layout integration.

Memory IC Selection Notes

Select this component when a non-volatile, one-time programmable memory solution is required for firmware storage. The 150 ns speed grade suits systems where minimal wait states are acceptable. Consider the 28-lead SOIC package for surface-mount assembly requirements. Evaluate power constraints against the specified active and standby current limits.

Memory IC Part Context

This part belongs to the AT27C512R series of OTP EPROMs originally designed by Atmel Corporation and now produced by Microchip Technology Inc. following the acquisition. The series offers various speed grades and package options to accommodate different system performance and physical layout needs.

Memory IC Replacement Considerations

Compatible substitutes include AT27C512R-15PC, AT27C512R-15TC, and AT27C512R-15JI, provided the package type and temperature range align with system requirements.
