Intrinsix SoC Silicon IP I2C Slave Interface

The Intrinsix I2C Slave Interface Silicon IP module is a gate efficient implementation of the Philips I2C, v2.1 specification.  The host port is a generic 8-bit interface that is readily adapted to industry standard bus architectures.  The I2C Slave Interface is a valuable component of the Intrinsix AMBA SoC Platform.

I2C Slave Interface Module capabilities: 

• Implements Philips Fast Mode (0 - 400kbps) I2C specification v2.1

• Fully synchronous design, supports full scan

• Built in 16-bit clock pre-scalar

• Built in digital filtering for glitch rejection per Philips I2C specification v2.1

• Available as RTL in industry standard formats

• 1,000 gates using 0.130μm TSMC

• 108 Slices on Xilinx Spartan 3 FPGA
