DESCRIPTION
The IN25АА020N/D
are a 2K
(256x8)
serial Electrically Erasable PROM with SPI interface.
*
The IN25АА040N/D
are a
4K (512x8)
serial Electrically Erasable PROM with SPI interface (SPI).
The ICs is purposed for reading, writing & nonvolatile data storage in electronic units with SPI interface. ICs
are realized in SO-8 (
MS-012АA) and DIP-8 (MS-001BA)
