Clock Speed The Microchip Technology Inc. 25AA512 is a 512 Kbit Byte and Page-level Write Operations: serial EEPROM memory with byte-level and page-level - 128-byte page serial EEPROM functions. It also features Page, Sector - 5 ms max. and Chip erase instructions typically associated with - No page or sector erase required Flash-based products. These instructions are not Low-Power CMOS Technology: required for byte or page write operations. The memory - Max. Write Current: 7 mA at 5.5V is accessed via a simple Serial Peripheral Interface - Read Current: 10 mA at 5.5V, 20 MHz (SPI) compatible serial bus. The bus signals required - Standby Current: 1A at 2.5V (Deep power- are a clock input (SCK) plus separate data in (SI) and down) data out (SO) lines. Access to the device is controlled by Electronic Signature for Device ID a Chip Select (CS) input. Self-Timed Erase and Write cycles: Communication to the device can be paused via the - Page Erase (5 ms, typical) hold pin (HOLD). While the device is paused, transi- - Sector Erase (10 ms/sector, typical) tions on its inputs will be ignored, with the exception of - Bulk Erase (10 ms, typical) Chip Select, allowing the host to service higher priority Sector Write Protection (16K byte/sector): interrupts. - Protect none, 1/4, 1/2 or all of array Packages Built-In Write Protection: 8-Lead DFN-S, 8-Lead PDIP, 8-Lead SOIC and - Power-on/off data protection circuitry 8-Lead SOIJ - Write enable latch - Write-protect pin High Reliability: Package Types (not to scale) - Endurance: 1 Million erase/write cycles - Data Retention: >200 years DFN PDIP/SOIC/SOIJ - ESD Protection: 4000V (MF) (P, SN, SM) Temperature Ranges Supported: 1 CS 8 VCC CS 1 8 VCC - Industrial (I):-40C to +85C 2 SO 7 HOLD SO 2 7 HOLD RoHS Compliant 3 WP 6 SCK 3 6 WP SCK Automotive AECQ-100 Qualified VSS SI 4 4 5 VSS 5 SI Pin Function Table Name Function CS Chip Select Input SO Serial Data Output WP Write-Protect VSS Ground SI Serial Data Input SCK Serial Clock Input HOLD Hold Input VCC Supply Voltage 2007-2021 Microchip Technology Inc.
