Clock VCC Range Packages Number (SDI) Backup Frequency 23 LCV1024 Yes Yes 20 MHz SN, ST, P. Features: Description: SPI-Compatible Bus Interface: The Microchip Technology Inc. 23 LCV1024 is a 1 Mbit - 20 MHz Clock rate Serial SRAM device. The memory is accessed via a - SPI/SDI mode simple Serial Peripheral Interface (SPI) compatible serial bus. The bus signals required are a clock input Low-Power CMOS Technology : (SCK) plus separate data in (SI) and data out (SO). - Read Current: 3 mA at , 20 MHz lines. Access to the device is controlled through a Chip - Standby Current: 4 A at +85 C Select (CS) input. Additionally, SDI (Serial Dual Inter- Unlimited Read and Write Cycles face) is supported if your application needs faster data External Battery Backup Support rates.
