Digital Blocks Extends its I2C Controller IP Core Family with More Enhanced Capabilities & System-Level Features

The DB-I2C IP Core Family targets applications with full CPU off-load requirements and deep system-level integration capabilities.

GLEN ROCK, New Jersey, June 17, 2014 – Digital Blocks, a leading developer of silicon-proven semiconductor Intellectually Property (IP) soft cores for system-on-chip (SoC) ASIC, ASSP, & FPGA developers with Embedded Processor & Peripherals requirements, announces 2014 extensions to its DB-I2C-MS / DB-I2C-M / DB-I2C-S I2C Controller IP Core family, with the following enhanced system-level features & integration capabilities:

  • Full range of I2C Bus Speeds: Standard mode (100 Kb/s), Fast mode (400 Kb/s), Fast mode plus (1 Mbit/s), Ultra-Fast-mode (5 Mbit/s) & Hs mode (3.4+ Mb/s)
  • Finite State machine control unit to completely off-load the I2C transfer from the CPU
  • CPU Interface via parameterized FIFO with support for APB / AHB / AXI / AXI-lite / Avalon interconnect fabrics
  • DMA transfer between the I2C Bus & Memory (SDRAM / SRAM / FLASH)
  • Direct interface to user Registers within ASIC / ASSP / FPGA, for Master/Slave transfer across the I2C Bus
  • Enhanced SCL / SDA spike filtering capabilities
  • Enhanced Repeated Start capabilities

The DB-I2C family contains I2C compliant features: Multi-Mastering, Clock Synchronization, Arbitration, SCL held low by Slave, Repeated Start, 7/10-bit addressing, & General Call capabilities as well as 100 Kbs, 400 Kbps, 1 Mbps, 3.4 Mbps, & 5 Mbps I2C bus speeds.
