The W27C4096-12 is a 4-Megabit, 512K x 8, CMOS OTP (One-Time Programmable) EPROM manufactured by Winbond Electronics. This memory device is used for applications requiring permanent storage of data or code, where the contents do not need to be changed after programming.

Applications

• Embedded systems
• Microcontroller program storage
• Look-up tables
• Code storage for legacy systems
• Industrial control systems

Features

• 4-Megabit Density: Provides 4 megabits of non-volatile storage capacity.
• OTP Technology: One-Time Programmable, meaning it can only be programmed once.
• CMOS Technology: Low power consumption.
• Fast Access Time: 120ns access time for quick data retrieval.
• 512K x 8 Organization: Organized as 512 Kilobytes by 8 bits.

Benefits

• Permanent Data Storage: Ensures data retention even when power is removed, and can't be accidently overwritten.
• Low Power Consumption: CMOS technology minimizes power usage, extending battery life in portable applications.
• Fast Data Access: Quick access time improves system performance.
• Reliable Operation: Designed for robust and reliable data storage.
• Simple Interface: Easy to interface with microcontrollers and other digital circuits.

Additional Details

The W27C4096-12 is programmed using standard EPROM programmers. Once programmed, the data is permanently stored and cannot be erased. It operates within a specified voltage range (typically 5V). Detailed specifications, including access times, programming voltage, and operating temperature ranges, are available in the device's datasheet. It is commonly used in applications where the data or code is fixed and does not require updating.
