10 pcs - 25AA512-I/SN Microchip 25AA512-I/SN, 512kbit Serial EEPROM Memory, 250ns 8-Pin SOIC Serial-SPI

25AA512/25LC512 SPI Serial EEPROMMicrochip’s 25AA512/25LC512 family of devices are 32 Kbit SPI Serial EEPROMs available in a variety of package, temperature and power supply variants. Featured are Page, Sector and Chip Erase functions typically associated with Flash based products.The Serial Peripheral Interface (SPI) is utilised to provide the required Clock Input (SCK), Data In (SI) and Data Out (SO) signals. The operation of these devices can be paused via a Hold pin (HOLD) which causes inputs to be ignored with the exception higher priority interrupts defined via the Chip Select (CS) pin.Features20 MHz maximum Clock SpeedByte and Page-level Write Operations (5 ms maximum): No page or sector erase required128-byte PageMaximum Write Current: 5 mA at 5.5V, 20 MHzRead Current: 10 mA at 5.5V, 20 MHzStandby Current: 1μA at 2.5V (Deep power-down)Electronic Signature for Device IDSelf-Timed Erase and Write Cycles: Page Erase (5 ms typical), Sector Erase (10 ms/sector, typical) and Bulk Erase (10 ms, typical)Sector Write Protection (16K byte/sector): Protect none, 1/4, 1/2 or all of arrayBuilt-In Write Protection: Power-on/off data protection circuitry, Write enable latch Write-protect pinEndurance: 1 Million erase/write cyclesData Retention: >,200 yearsESD Protection: >,4000VEEPROM Serial Access - Microchip
