The I2C Master IP Controller implements an I2C Master fully compliant to the I2C-bus specification and user manual Rev. 5 – 9 October 2012 for Standard-mode, Fast-mode and Fast-mode Plus (Fm+). The Inter-Integrated Circuit (I2C) is a multi-master, multi-slave, single-ended, serial computer bus invented by Philips Semiconductor (now NXP Semiconductors). The I2C bus is typically used for attaching lower-speed peripheral ICs to processors and microcontrollers.

The I2C Slave IP Controller implements an I2C Slave fully compliant to the I2C-bus specification and user manual Rev. 5 – 9 October 2012 for Standard-mode, Fast-mode and Fast-mode Plus (Fm+). The Inter-Integrated Circuit (I2C) is a multi-master, multi-slave, single-ended, serial computer bus invented by Philips Semiconductor (now NXP Semiconductors). The I2C bus is typically used for attaching lower-speed peripheral ICs to processors and microcontrollers.

The Universal Asynchronous Receiver/Transmitter (UART) is a hardware device that translates data between parallel and serial forms. UARTs are commonly used in conjunction with communication standards such as TIA (formerly EIA) RS-232, RS-422 or RS-485. The universal designation indicates that the data format and transmission speeds are configurable. The electric signaling levels and methods (such as differential signaling etc.) are handled by a driver circuit external to the UART.

The SPI Master IP Core implements an SPI Master fully compliant to the SPI Standard (Motorola’s M68H11 Reference Manual).

The SPI Slave IP Core implements an SPI Slave fully compliant to the SPI Standard (Motorola’s M68H11 Reference Manual).
