SPI Slave Serial Interface Controller

General Description

Slave serial interface compatible with the popular SPI™ standard. Permits an SPI Master to communicate with your FPGA, ASIC or SoC. The SPI Slave supports up to 512 custom registers that are accessible using a set of simple SPI read and write commands.

Key Design Features

- Fully SPI compliant
- Simple command interface
- Configurable number of 8-bit config registers (max 256)
- Configurable number of 8-bit status registers (max 256)
- Configurable clock polarity (CPOL)
- Configurable clock phase (CPHA)
- Typical FPGA comms up to 50 Mbits/s

Applications

- Inter-chip board-level communications
- Simple method to add SPI-accessible control registers to your FPGA, ASIC or SoC
- Serial comms at higher data rates than other protocols such as UART, I2C and USB1.x
