IC/Module: 23K640 64K SPI Bus Low-Power SRAM
The 23K640 is a 64 Kbit SRAM device that access memory via a simple SPI compatible serial bus. The bus signals required are a clock input (SCK) with separate data in (SI) and data out (SO) lines. Access to the device is controlled through a Chip Select (CS) input. It has a hold pin (HOLD) to pause communication to the device.
The Serial RAM Board can be easily connected to a development system’s port through a 2x5 connector CN1. It also has an onboard jumper J1 that can be set to appropriate positions to connect to 3.3V and 5V development system. The DIP switch is used to set which pins are used for MISO/MOSI/SCK, and the silkscreen marking describes the settings required for specific MikroElektronika development systems with a matching IDC10 header.
