Supplied in bulk (tube) packaging, it's suited for prototype runs or low-volume production where tape-and-reel isn't required. ## Active lifecycle — no end-of-life risk Microchip lists this part as Active in production, so you can design it into new builds without worrying about a last-time-buy window.","metaTitle":"Microchip AT93C46D-SP25DX EEPROM, 1Kbit, 3-Wire, 8-SOIC","metaDescription":"AT93C46D-SP25DX 1Kbit EEPROM from Microchip, 2 MHz clock, 1.8-5.5V supply, -40°C to +85°C.
