Product details

Parametric profile for the BOM engineer

Organised as 64K x 8 bits (512 Kbit total), the 25LC512-M/SN communicates over an SPI bus at up to 20 MHz clock frequency — fast enough for configuration storage or data logging in most embedded applications without saturating the bus. The operating temperature range of -55°C to +125°C qualifies it for harsh environments — avionics, downhole instrumentation, or engine-bay modules where commercial-grade parts would fail.

Supplied in Tube packaging, which is the typical format for manual pick-and-place or small-batch assembly; for high-volume reels, the tape-and-reel variant (25LC512-M/SNT) is the ordering code to specify.
