• Includes hardware data protection mechanisms such as Vcc sense and power-on delay.
• Features two designated 8K-byte boot blocks with independent programming lockout capabilities.
• Provides DATA polling and Toggle Bit functions for end-of-program cycle detection.

Memory IC Applications

• In-system reprogrammable code storage
• Boot block applications requiring secure code protection
• Embedded systems utilizing 3-volt logic interfaces

Memory IC Procurement Notes

Verify the manufacturer designation, as this component was originally produced by Atmel Corporation before its acquisition by Microchip Technology. Confirm that the PLCC package type matches the specific board layout requirements. Ensure the system design accounts for the 'Not Recommended for New Designs' status indicated in the official documentation.

Memory IC Selection Notes

Select this component when a 3-volt only operation is required for legacy designs or specific maintenance scenarios. The 200 ns access speed suits moderate-speed asynchronous applications. Consider the industrial temperature variant if operating conditions exceed the commercial range limits defined in the datasheet specifications.

Memory IC Part Context

This part belongs to the AT29LV010A series of 3-volt Flash memories manufactured using advanced nonvolatile CMOS technology. The series offers various access times and package options, including TSOP configurations. The device provides software-protected programming and sector erase operations without requiring high input voltages.

Memory IC Replacement Considerations

Official documentation explicitly recommends using the AT29BV010A as the replacement for new designs. Verify pin compatibility and voltage level tolerances when transitioning from the LV series to the BV series components.
