The MikroE SRAM Click Board™ is a storage add-on board that carries the 23LC1024 IC, which allows the user to add 1Mbit of additional SRAM (static RAM) memory to the device. Based on low-power CMOS technology, the 23LC1024 chip outlines the memory in 8-bit instruction registers and 32-byte pages (128K x 8-bit). For Read and Write operations, this highly-reliable chip offers byte, page, and sequential operating modes. The sequential mode enables Read/Write operation for an entire memory array.
It supports unlimited Read/Write cycles to the memory array with zero Write time. It operates at a clock rate of 20 MHz for all the three Read/Write modes. Communicating through SPI-Compatible bus interface, the board also has an additional Hold pin functionality in place of the default RST pin. SRAM Click Board™ can be used with either 3.3V or 5V power supply.
