The Sequential Read bus signals required are a clock input (SCK) plus High Reliability: separate data in (SI) and data out (SO) lines. Access to - Endurance: 1,000,000 erase/write cycles the device is controlled through a Chip Select (CS) - Data retention: >200 years input. - ESD protection: >4000V Communication to the device can be paused via the RoHS Compliant hold pin (HOLD). While the device is paused, transitions on its inputs will be ignored, with the Temperature Ranges exception of Chip Select, allowing the host to service - Industrial (I): -40Cto +85C higher priority interrupts. - Extended (E): -40C to +125C Automotive AEC-Q100 Qualified Note 1: 25XX128 is used in this document as a Packages generic part number for the 25AA128/ 25LC128 devices. 8-Lead DFN, 8-Lead PDIP, 8-Lead SOIC, 8-Lead SOIJ and 8-Lead TSSOP TSSOP Rotated TSSOP PDIP/SOIC/SOIJ DFN 11 88 VCC 1 8 VCC CS CS CS 1 8 VCC 1 8 HOLD SCK SO 22 77 SO 2 7 HOLD HOLD SO 2 7 VCC 2 7 HOLD SI 3 6 SCK 3 6 VSS 3 6 SCK 33 66 SCK WP WP CS WP 4 5 SI 4 5 4 5 SI SO WP VSS VSS 44 55 SI VSS 2003-2021 Microchip Technology Inc.
