AT27C2048-15VI

Memory IC Overview

The AT27C2048-15VI is a 2-Megabit (128K x 16) one-time programmable read-only memory manufactured by Microchip Technology. It features a fast read access time of 150 ns and operates on a single 5V ± 10% power supply. The device is housed in a 40-lead VSOP package and supports industrial temperature ranges from -40°C to +85°C. Key electrical characteristics include a maximum active current of 35 mA at 5 MHz and a standby current of 100 µA.

Memory IC Feature Summary

• High-speed data retrieval with access times as low as 55 ns
• Low-power CMOS operation for efficient energy usage
• Integrated product identification code for automated programming
• Rapid programming algorithm for reduced write cycle duration

Memory IC Applications

• Firmware storage in high-performance microprocessor systems
• Data retention in 16-bit and 32-bit computer architectures
• Industrial control system logic storage
• Automotive electronic module configuration

Memory IC Procurement Notes

Verify the specific suffix 'VI' corresponds to the Industrial temperature range (-40°C to +85°C) and the 40-lead VSOP package format. Confirm that the ordering code matches the required 150 ns speed grade. Ensure compatibility with existing 5V logic levels and check for moisture sensitivity handling requirements during assembly.

Memory IC Selection Notes

Select this component when a 16-bit data bus interface is required for firmware storage. The VSOP package is suitable for applications needing surface-mount technology with space constraints. Consider the 150 ns access time against system clock speeds to determine if wait states are necessary. Verify that the programming equipment supports the Rapid™ algorithm and 13V VPP requirement.

Memory IC Part Context

This part belongs to the AT27C2048 family of 2-Megabit OTP EPROMs. It serves as a direct upgrade path for smaller density devices like the AT27C516 and AT27C1024. The family maintains pin-out compatibility across different speed grades and package types, facilitating design-in flexibility for various memory capacity needs.

Memory IC Replacement Considerations

Compatible substitutes include other AT27C2048 variants with different speed grades or packages, such as AT27C2048-55VI or AT27C2048-90PC. Cross-referencing with JEDEC standard EPROM pinouts ensures functional interchangeability within the same density class.
