IN25АА020N, IN25АА020D, IN25АА040N, IN25АА040D
NONVOLATILE ELECTRICALLY ERASABLE PROM WITH SERIAL
PERIPHERAL INTERFACE (SPI).
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)
