Texas Instruments TMS27C040-15JE Overview

The Texas Instruments TMS27C040-15JE is a high-performance, 4-megabit (512K x 8) UV erasable and programmable read-only memory (EPROM) integrated circuit. This device is designed for applications requiring large non-volatile memory storage and where the data is typically programmed into the device only once or infrequently updated. It is particularly well-suited for program storage in systems where fast read access is required.

Key Features

• Memory Size: 4 Megabit (512 K x 8)
• Access Time: 150 ns
• Single 5V Power Supply: Simplifies the power design for the system, making it ideal for a wide range of applications.
• Package: The TMS27C040-15JE comes in a 32-lead JEDEC-standard plastic cerdip (CDIP) package, which is known for its durability and reliability in harsh environments.
• Extended Temperature Range: It operates over an extended temperature range, making it suitable for industrial applications.
• Industry-Standard Pinout: This device follows the industry-standard pinout for EPROMs, allowing for easy integration into existing designs without the need for board changes.

Applications

With its robust design and large storage capacity, the TMS27C040-15JE is ideal for a variety of applications, including:

• Embedded systems
• Microprocessor-based systems
• Computer BIOS chips
• Industrial control systems
• Telecommunication equipment
• Automotive electronics

Programming and Erasure

The TMS27C040-15JE is designed to be programmed by a variety of EPROM programmers available in the market. The programming process is straightforward and can be easily integrated into the product manufacturing process. For erasure, the device requires exposure to ultraviolet (UV) light, which can be achieved using a standard EPROM eraser. This feature allows for the reuse of the device after testing or if updates are necessary.

Reliability and Quality

As with all Texas Instruments products, the TMS27C040-15JE is manufactured to the highest quality standards. Texas Instruments' commitment to quality ensures that this EPROM provides reliable storage for critical data in a wide range of operating conditions.
