Microchip Technology, Inc. 512Kb SPI Serial SRAM with Battery Backup en559070

Description
The Microchip Technology Inc. 23LCV512 are 512 Kbit Serial SRAM devices. 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 the device is controlled through a Chip Select (CS) input. Additionally, SDI (Serial Dual Interface) is supported if your application needs faster data rates. The SRAM can be battery backed via the Vbat pin essentially making the SRAM non-volatile. The device also supports unlimited read and write cycles to the array. The 23LCV512 is available in standard packages including 8-lead SOIC, PDIP and advanced 8-lead TSSOP. Additional Features SPI-compatible Bus Interface- 20 MHz Clock rate- SPI/SDI Mode Low-Power CMOS Technology:- Read Current: 3 mA at 3.6V, 20 MHz- Standby Current: 4 uA Max. at +85°C Unlimited read and write cycles Zero write time 64K x 8-bit organization- 32 Byte Page Battery-backed SRAM Support via Vbat Pin- Automatic switchover to Vbat Sequential Mode reads and writes High Reliability Temperature Ranges Supported: -40C to +85C Pb-Free and RoHS Compliant, Halogen Free 8 Lead SOIC, TSSOP and PDIP Packages
