AT27C2048-90JU-T

Memory IC Overview

The AT27C2048-90JU-T is a 2 Mbit (128K x 16) one-time programmable read-only memory (OTP EPROM). It features a 90 ns access time and operates on a single 5V supply. The device utilizes a 44-lead PLCC package and supports industrial temperature ranges from -40°C to +85°C. Standby current is limited to 100 µA maximum, while active consumption reaches 35 mA at 5 MHz.

Memory IC Feature Summary

Low-power CMOS architecture with high-reliability technology
Integrated product identification code for automated programming
Direct upgrade path from legacy 512Kbit and 1Mbit EPROMs
CMOS and TTL compatible inputs and outputs

Memory IC Applications

High-performance 16-bit microprocessor systems
High-performance 32-bit microprocessor systems
Firmware storage applications requiring rapid programming

Memory IC Procurement Notes

Verify the manufacturer origin, as this component was originally produced by Atmel before acquisition by Microchip Technology. Confirm the specific suffix 'T' indicates tape and reel packaging if required for automated assembly processes. Ensure the ordering code matches the exact speed grade and package variant needed for the design.

Memory IC Selection Notes

Select this part when a 16-bit data bus organization is required for firmware storage in microprocessor systems. The 90 ns speed grade offers a balance between performance and power consumption. Consider the integrated product ID feature to simplify the programming workflow using industry-standard equipment without manual algorithm selection.

Memory IC Part Context

This component belongs to the AT27C2048 series of OTP EPROMs. It serves as a density upgrade over the AT27C516 and AT27C1024 devices. The device is designed for applications where non-volatile storage is needed without the complexity of mass media, providing direct word access without wait states.
