DESCRIPTION
The Microchip Technology Inc. 23LCV1024 is a 1-Mbit Serial SRAM device. Access to the device is controlled through a Chip Select (CS) input. Additionally, Serial Dual Interface (SDI) is supported if the application needs faster data rates. This device also supports unlimited reads and writes to the memory array and supports data backup via an external battery/coin cell connected to VBAT (pin 7).
