The 5 ms write cycle time per word or page governs firmware-update throughput: a full 128-Kbit page write (16K x 8) takes about 320 ms at the page level. For a data logger writing 32 bytes every event, the EEPROM keeps up with 200 events/second before the write-cycle latency becomes the bottleneck. ## Supply voltage, temperature grade, and compliance The ROHS3 compliance means it ships without the six restricted substances plus four phthalates, clearing EU and UKCA import gates without an exemption declaration. ## Sourcing posture and drop-in alternatives The Tape & Reel (TR) and Cut Tape (CT) packaging options let you order reel quantities for production or cut tape for prototyping without a minimum-order surcharge.","metaTitle":"STMicroelectronics M95128-WMN6TP 128Kbit SPI EEPROM, 20 MHz","metaDescription":"STMicroelectronics M95128-WMN6TP 128Kbit SPI EEPROM, 20 MHz clock, 2.5-5.5V supply, -40°C to 85°C, 8-SOIC.
