High-precision IEEE 1588 MCU and module

6 February 2008 DSP, Micros & Memory

IEEE 1588 is a clock synchronisation standard for communication devices, which has seen a dramatic increase in interest over the past year.

It is today seen as a fundamental cornerstone for future communication systems - wired and wireless, professional and consumer. IEEE 1588 enables these to be synchronised to GPS accuracy and enables the quality of service required for future communication systems. A company called Imsys is addressing these new, demanding applications with the introduction of the IM3220-BA10 MCU and the single board reference module that have been shown to deliver telecom, ITU G.8261, compliance.

The IM3220 combines features of traditional CISC architectures and efficient use of resources with FPGA flexibility for the predefined application of time synchronisation. It reduces the cost of the external (local) oscillator when high precision time is communicated by the IEEE 1588 protocol. The MCU, measuring 24 x 45 mm, supports two 10/100 Ethernet ports, three UARTs at 920 Kbps, I²C or SPI port, and eight DMA channels with a sustained 83 MBps throughput.

According to Imsys, the IM3220's unique memory-centric architecture reduces the program memory requirements by 75 to 80% compared to a RISC architecture, while consuming less than 10% of the power of competing solutions.

Imsys' complete offering includes RTOS, TCP/IP-stack, fail-safe Flash file system, and an IEEE 1588 protocol stack.
