Designed to work with a wide variety of SPI bus variants, the core supports run-time control of several SPI protocol parameters. For example, the SPI frame width can be 1 to 4 bytes, the
most significant bit position in a frame, serial clock phase and polarity are all software- programmable. In master mode the core can control up to 32 slaves. A software controllable clock generator derives the serial clock for master mode, by dividing the frequency of a clock line dedicated for that purpose
The CAN protocol uses a multi-master bus configuration for the transfer of frames be- tween nodes of the network and manages error handling with no burden on the host processor. The core enables the user to set up economic and reliable links between vari- ous components. It appears as a memory-mapped I/O device to the host processor, which accesses the CAN core to control the transmission or reception of frames.
The CAN core is easy to use and integrate, featuring programmable interrupts, data and baud rates; a configurable number of independently programmable acceptance filters; and a generic processor interface or optionally an AMBA APB, or AHB-Lite interface. It imple- ments a flexible buffering scheme, allowing fine-tuning of the core size to satisfy the requirements of each specific application

109.850 K μm^2
It is used to generate a stable, high-speed clock from an external slower clock signal. It integrates one Voltage-Controlled Oscillator (VCO), one Phase-Frequency Detector (PFD), one Low-Pass Filter (LPF), one 8-bit programmable divider, and other associated support circuitries. This PLL supports an operating voltage ranging from 0.81 V to 0.99 V with an operating junction temperature ranging between -40 °C and 125 °C. This IP uses the input operating frequency of PFD ranging from 6 MHz to 25 MHz and generates the output frequency ranging from 25 MHz to 1300 MHz.
The jitter performance of a PLL is highly dependent on the floor plan of ASIC. Because PLL is a sensitive cell when integrated into an ASIC design, the best way to maximize its capacity is to keep PLL away from the noisy blocks in the core region, such as the memory block and the high-driving logic circuit, and the I/O region, such as the high-driving I/O. This PLL must be placed around the I/O area. Providing sufficient space between this PLL and the noisy blocks is a simple and effective approach to reduce the coupled substrate noise.
