25AA512

The 25AA512/25LC512 (25XX512*)(512 Kbit SPI Bus Serial EEPROM) possesse the features of 20 MHz max. Clock Speed, Low-Power CMOS Technology(Max. Write Current: 5 mA at 5.5V, 20 MHz; Read Current: 10 mA at 5.5V, 20 MHz; Standby Current: 1A at 2.5V (Deep power-down)), Byte and Page-level Write Operations(128-byte page; 5 ms max.; No page or sector erase required), Electronic Signature for Device ID, Self-Timed Erase and Write cycles(Page Erase (5 ms, typical); Sector Erase (10 ms/sector, typical); Bulk Erase (10 ms, typical)), Sector Write Protection (16K byte/sector)(Protect none, 1/4, 1/2 or all of array), High Reliability(Endurance: 1 Million erase/write cycles), Built-In Write Protection(Power-on/off data protection circuitry; Write enable latch; Write-protect pin), Temperature Ranges Supported(Industrial (I): -40°Cto +85°C; Automotive (E): -40°C to +125°C), Pb-free and RoHS Compliant.
The Microchip Technology Inc. 25AA512/25LC512 (25XX512*) is used in this document as a generic part number for the 25AA512, 25LC512 devices.)a 512 Kbit serial EEPROM memory with byte-level and page-level serial EEPROM functions. 25AA512/25LC512 (25XX512*) also features Page, Sector and Chip erase functions typically associated with Flash-based products. These functions are not required for byte or page write operations. The memory is accessed via a simple Serial Peripheral Interface (SPI) compatible serial bus. The bus signals required are a clock input (SCK) plus separate data in (SI) and data out (SO) lines. Access to thedevice is controlled by a Chip Select (CS) input. Communication to the device can be paused via the hold pin (HOLD). While the device is paused, transitions on its inputs will be ignored, with the exception of Chip Select, allowing the host to service higher priority interrupts. The 25AA512/25LC512 (25XX512*) is available in standard packages including 8-lead PDIP, SOIC, and advanced 8-lead DFN package. All packages are Pb-free and RoHS compliant.
Pin Function terms of 25AA512/25LC512 (25XX512*) are also be known here, Chip Select Input(CS), Serial Data Output(SO), Write-Protect(WP), Ground(Vss), Serial Data Input(SI), Serial Clock Input(SCK), Hold Input(HOLD), Supply Voltage(Vcc).
