Flash 2 click is a mikroBUS™ add-on board for adding more Flash Memory to your target board microcontroller. It carries Microchip’s SST26VF064B flash-memory module with 64 Mbits capacity. It’s a highly reliable module with a specified minimum of 100,000 read and write cycles and with over 100 years of Data Retention. For data security, the module features a One-Time Programmable (OTP) 2 KB bit secure ID and a 64 bit unique, factory pre-programmed identifier. Additional software security measures include inidividual-block write Protection with permanent lock-down capability. Flash 2 click communicates with the target MCU through the mikroBUS™ SPI interface (CS#, SCK, MISO, MOSI) with additional functionality provided by the #HOLD pin (in place of default mikroBUS™ RST pin). The board is designed to use a 3.3V power supply.
