23LC512T-I/SN

The 23A512/23LC512 are 512Kbit 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) and SQI (Serial Quad Interface) is supported if your application needs faster data rates. This device also supports unlimited reads and writes to the memory array. The 23A512/23LC512 is available in standard packages including 8-lead SOIC, PDIP and advanced 8-lead TSSOP. The 23A512/23LC512 is designed to interface directly with the Serial Peripheral Interface (SPI) port of many of today's popular microcontroller families. It may also interface with microcontrollers that do not have a built-in SPI port by using discrete I/O lines programmed properly in firmware to match the SPI protocol. In addition, the 23A512/23LC512 is also capable of operating in SDI/SQI high speed SPI mode.
