2. Soldering the headers Before using your click board , make sure to solder 1x8 male headers to both left and right side of the board. Two 1x8 male headers are included with the board in the package. 1 SRAM click 2 3 4. Essential features The 23LC1024 IC 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 Turn the board upside down so that Turn the board upward again. Make sure three modes is up to 20MHz. The HOLD pin, the bottom side is facing you upwards. to align the headers so that they are when pulled low, suspends data transmission Place shorter pins of the header into the perpendicular to the board, then solder the mid-sequence (without causing the reset of appropriate soldering pads. pins carefully. the entire sequence). 1.

The board communicates Once you have soldered the headers your with the target MCU through the mikroBUS board is ready to be placed into the desired BOARD SPI interface (MISO, MOSI, SCK, CS) with mikroBUS socket. Make sure to align the cut www.mikroe.com additional HOLD functionality provided in the lower-right part of the board with the through the default mikroBUS RST pin. markings on the silkscreen at the mikroBUS SRAM click is designed to use either a 3.3V socket.
