The 5 ms page write cycle is the time the part is busy after a write; the master must poll the acknowledge or wait this interval before sending the next command. At 128 Kbytes, a full-chip rewrite at one byte per write would take over 10 minutes — use the page-write mode (up to 64 bytes per cycle) to cut that to under 3 seconds. ## Package and footprint — 8-SOIJ The 8-SOIC (0.209\", 5.30 mm width) package with the supplier device code 8-SOIJ is a standard narrow-body SOIC-8 footprint. The 'J' suffix indicates a JEDEC-standard SOIC with a 1.27 mm pitch — the same land pattern as the common SOIC-8. The 5.30 mm body width is the narrow version, so the pad spacing matches the standard 0.050-inch pitch. Tape & Reel packaging is the production-friendly format for pick-and-place; the Cut Tape option works for prototypes or low-volume builds.","metaTitle":"Microchip 24LC1025T-E/SM 1Mbit I²C EEPROM, 400 kHz","metaDescription":"Microchip 24LC1025T-E/SM 1Mbit I²C EEPROM, 400 kHz, 2.5-5.5V, -40°C to +125°C, 8-SOIJ.
