SRAM click - example

SRAM click lets you add 1 Mbit of additional SRAM memory to your devices, via the 23LC1024 chip. It organizes the memory in 8-bit instruction registers and 32-byte pages. Three operating modes for reading and writing data are available: byte, page, and sequential (the last one allows read/write for entire memory array). The clock rate for all three modes is up to 20MHz. The board communicates with the target MCU through the mikroBUS™ SPI interface (MISO, MOSI, SCK, CS) with additional HOLD functionality provided through the default mikroBUS™ RST pin. SRAM click is designed to use either a 3.3V or 5V power supply.
