Hs-Mode I2C Controller - 3.4 Mbps, Slave w/FIFO

Overview

Key Features

• I2C Slave Controller - Implements Slave-only protocol for smaller VLSI footprint:
• Slave–Transmitter
• Slave–Receiver
• Supports four I2C bus speeds:
• Hs-Mode (3.4+ Mb/s)
• Fast Mode Plus (1 Mbit/s)
• Fast Mode (400 Kb/s)
• Standard Mode (100 Kb/s)
• Digital Blocks optionally supplies a RTL Parameterized Register Array the user can use to construct their registers, or a Register Array / SDRAM / SRAM / Flash / FIFO Interface the user can use to connect to their existing designs, or an AHB / APB / AXI / Avalon Master interface the user can connect Memory or Peripherals to that are participating in the I2C transfer.
• DB-I2C-S-Hs-Mode Controller supports single register / memory access or burst access with address auto-increment capability.
• 7- or 10-bit addressing, General Call, SCL Low Wait States
• Enhanced SCL / SDA spike filtering capabilities
• 13 sources of internal interrupts with masking control
• Compliance with I2C specifications:
• Compliance with AMBA AXI / AHB/ APB Protocol Specifications
• Compliance with Avalon / Qsys Protocol Specifications
• Philips – The I2C-Bus Specification, Version 2.1, January 2000
• NXP Rev .5 October 9, 2012
• Fully-synchronous, synthesizable Verilog RTL core, with rising-edge clocking, no gated clocks, and no internal tri-states, for easy integration into FPGA or ASIC design flows.

Benefits

• The DB-I2C-S-Hs-Mode I2C Slave Controller IP Core targets embedded applications where the I2C Slave Controller connects to a bank of registers and a block of Control & Status Register bytes must be transferred to or from the registers, or a memory device such as SDRAM / SRAM / FLASH / FIFO or an AHB / APB / AXI / Avalon Bus Peripheral must be interfaced to the I2C Bus. The DB-I2C-S IP Core functions standalone, without the requirement for an embedded processor.
