It stores calibration constants, device configuration, boot parameters, or small firmware patches that need field updates without reprogramming the main flash. ## 500 ns access, 5 ms page write — timing budget for the firmware loop Random read access is 500 ns max after the address byte, which sets the ceiling on back-to-back sequential reads across the I²C bus. The 1 MHz clock rate yields a raw 125 kbyte/s throughput on the bus, but the actual read rate is lower once the EEPROM's internal access time and the master's acknowledge polling are factored in. Page write completes in 5 ms typical — budget this into the firmware update routine: a full 64K x 8 rewrite takes roughly 320 ms if written page-by-page with no bus contention. The write cycle time is the same whether writing one byte or a full page, so burst writes are more efficient. ## 8-TSSOP footprint and rework considerations Housed in an 8-lead TSSOP (4.40 mm body width, 0.65 mm pitch), the package is small enough for dense layouts but still hand-reworkable with a hot-air station. The 0.65 mm pitch means the solder paste stencil aperture should be sized to avoid bridging between adjacent pins — a 0.30 mm stencil thickness with 1:1 aperture-to-pad ratio is a common starting point. Pin 1 is marked by a dot on the package top and a chamfered corner — both are visible under magnification after reflow, so orientation is clear even if the board silk screen is faint. The low pin count and wide lead span (relative to the body) make it forgiving for hand placement. ## Active lifecycle and compliance documentation No minimum order quantity restrictions apply beyond the reel increment.","metaTitle":"M24512-RDW6TP 512Kbit I²C EEPROM, 1 MHz, 8-TSSOP","metaDescription":"STMicroelectronics M24512-RDW6TP 512Kbit I²C EEPROM, 1 MHz clock, 500 ns access, 1.8-5.5 V supply, -40 to +85°C, 8-TSSOP.
