AT29LV020-10JC

Memory IC Overview

The AT29LV020-10JC is a 3-volt-only in-system Flash programmable and erasable read-only memory (PEROM) manufactured by Atmel. It provides 2 megabits of storage organized as 256K x 8 bits. The device features a fast access time of 100 ns, an active current of 15 mA, and a CMOS standby current of 40 µA. It operates within the commercial temperature range of 0°C to 70°C and utilizes a 32-lead PLCC package.

Memory IC Feature Summary

• Supports single voltage 3V to 3.6V supply with software protected programming
• Features sector program operation with internal address and data latches for 256 bytes
• Includes two 8K byte boot blocks with independent lockout capabilities
• Provides hardware data protection via VCC sense and power on delay

Memory IC Applications

• In-system reprogrammability applications
• Systems requiring secure code booting from lower or higher memory addresses
• Embedded systems utilizing 3-volt logic interfaces

Memory IC Procurement Notes

Verify the manufacturer origin, as this component was originally produced by Atmel. Confirm that the specific ordering suffix matches the required package type and operating temperature range. Ensure compatibility with existing system designs, noting that this product family may not be recommended for new designs.

Memory IC Selection Notes

Select this component when a 3-volt only Flash memory solution with sector-based programming is required. Consider the 100 ns access speed and 2-megabit density for suitable performance levels. Evaluate the need for boot block lockout features if protecting critical startup code is necessary for the application.

Memory IC Part Context

This part belongs to the AT29LV020 series of 3-volt Flash memories. It shares architectural similarities with other densities in the line but offers specific 256K x 8 organization. The device utilizes advanced nonvolatile CMOS technology to achieve low power dissipation while maintaining high-speed read and write operations.

Memory IC Replacement Considerations

Check for alternative part numbers within the same series offering different access times or packages. Verify if newer generations from the manufacturer provide pin-compatible upgrades with improved endurance or additional features.
