AT27LV512A-70JC

Memory IC Overview

The AT27LV512A-70JC is a 524,288-bit (64K x 8) one-time programmable read-only memory manufactured by Microchip Technology. It features a fast access time of 70 ns and supports dual voltage operation with a low-voltage range of 3.0V to 3.6V or a standard 5V ± 10% supply range. The device operates within commercial temperature limits from 0°C to 70°C and is housed in a 32-lead PLCC package.

Memory IC Feature Summary

• Dual voltage capability for 3.3V portable systems and 5V host compatibility
• Rapid programming algorithm ensuring reliable byte-level writes
• Integrated product identification code for automated programming
• High reliability CMOS technology with ESD protection

Memory IC Applications

• Battery-powered portable electronic systems
• Industrial control logic storage
• Embedded firmware retention
• Consumer electronics configuration data

Memory IC Procurement Notes

Verify the specific suffix 'JC' confirms the 70 ns speed grade and commercial temperature range. Ensure the ordering code matches the required 32-lead PLCC package type. Confirm that the component is sourced as an OTP device requiring dedicated programming equipment before final procurement decisions.

Memory IC Selection Notes

Select this component when a non-volatile, one-time programmable solution is required for 64Kx8 bit storage. It is suitable for designs needing flexibility between 3.3V and 5V power rails without level shifting. Consider the Rapid programming algorithm if manufacturing throughput is a priority over reprogrammability.

Memory IC Part Context

This part belongs to the AT27LV series of low-voltage OTP EPROMs. It is functionally compatible with the JEDEC standard AT27C512R but offers reduced power consumption. The device utilizes Atmel's high-reliability CMOS technology to provide performance comparable to 5V parts while maintaining low standby currents.

Memory IC Replacement Considerations

The AT27C512R is a documented electrically compatible alternative. Verify pinout and voltage requirements match the existing design constraints before substitution.
