This is a recycled and previously used W27C020-70 ROM, a reliable and cost-effective solution for your storage needs. This flash memory chip offers 2 megabit (256K x 8) of non-volatile storage, making it ideal for storing critical firmware, software, or data in a wide range of electronic applications.
Programming: This chip can be programmed with the Relatively Universal ROM Programmer (RURP) and is supported by the Firestarter software. Select the chip profile that matches this exact part and its datasheet programming voltage.
Typical uses: Electrically erasable parallel ROM for code in older digital systems. Programming requires the correct voltages.
Beware this IC needs a 14V erase and 12V programming voltage and is not programmable at 5V levels - luckily the Relatively Universal ROM Programmer shield will easily handle that.
Please be aware this is a used and discontinued IC and even though we test used IC's before reselling them, they should only be considered as a functional collector's item and comes with no guarantee it will keep functioning within the specs of the original datasheet.
The W27C020-70 provides fast and efficient read and write operations, allowing for quick access to your stored information. Its low power consumption ensures energy efficiency, making it suitable for battery-operated devices. With a sector erase and chip erase feature, you can easily manage and update your data.
This previously used EEPROM has been tested, but may need to have oxidation removed from pins before soldering or use in sockets.
It's an environmentally friendly option as it helps reduce electronic waste by repurposing previously used components.
Upgrade your storage capabilities with the W27C020-70 EEPROM, a sustainable choice for your electronic projects.
