Memory IC datasheet and documents for AT29C256-70JC
Memory IC Overview
The AT29C256-70JC is a 256K (32K x 8) five-volt-only Flash programmable and erasable read-only memory manufactured by Microchip Technology. It features a fast access time of 70 ns with an active current of 50 mA and a CMOS standby current of 300 µA. The device supports page programming for 64 bytes, hardware and software data protection, and operates within commercial temperature ranges.
Memory IC Feature Summary
- Supports in-system reprogrammability using only 5V supply voltages without requiring high input voltages.
- Features internal program control and timers to automate erase and program cycles.
- Includes hardware and software mechanisms to protect against inadvertent writes during power transitions or noise events.
Memory IC Applications
- In-system code storage for microcontrollers
- Data logging applications requiring frequent updates
- Configuration storage in industrial equipment
Memory IC Procurement Notes
Verify the specific package type required for your design, as the JC suffix indicates a 32-lead PLCC package. Confirm that the commercial temperature range meets your operational environment requirements. Ensure your system provides stable 5V power to meet the specified voltage tolerances.
Memory IC Selection Notes
Select this component when a 70 ns access speed is required for 256K nonvolatile storage. It is suitable for designs needing single 5V operation and page programming capabilities. Consider the PLCC package constraints if surface mount alternatives are preferred.
Memory IC Part Context
This part belongs to the AT29C series of 5V-only Flash memories from Microchip Technology. It is designed to replace older EPROMs and EEPROMs in systems requiring faster write speeds and higher endurance. The device utilizes CMOS technology for low power consumption while maintaining TTL compatibility.
Memory IC Replacement Considerations
Check for AT29C256 variants with different access times or packages. Verify pinout compatibility with existing designs before substitution.
