![]() ![]() ![]() It has also connector for in-circuit serial programming (ICSP) with buffered I/O. It supports EEPROM, FLASH and FRAM with 1.8V, 2.5V, 3.3V and 5V power supply. Professional serial memory programmer for I2C, SPI and uWire devices. SPI bus timing If CPOL and CPHA are both ‘0’ (defined as Mode 0) data is sampled at the leading rising edge of the clock. The SCK, MOSI, and MISO signals can be shared by slaves while each slave has a unique SS line. SPI Interface As shown in Figure 1, a standard SPI connection involves a master connected to slaves using the serial clock (SCK), Master Out Slave In (MOSI), Master In Slave Out (MISO), and Slave Select (SS) lines. The Serial Peripheral Interface (SPI) bus was developed by Motorola to provide full-duplex synchronous serial communication between master and slave devices. SPI (Serial Peripheral Interface) is an interface bus commonly used for communication with flash memory, sensors, real-time clocks (RTCs), analog-to-digital converters, and more. ![]()
