Zilog Inc. and CMX Systems have announced the availability of the CMX-MicroNet TCP/IP stack and the CMX-RTX RTOS ported to the Zilog eZ80Acclaim!, and the CMX-Tiny+ RTOS and CMX-MicroNet TCP/IP stack ported to the Z8 Encore!TM microcontrollers.

The collaboration between Zilog and CMX will provide customers an "off-the-shelf" solution for adding low cost TCP/IP connectivity to embedded systems designs. According to Michael Gershowitz, director of MicroDevices Product Marketing for Zilog, "The eZ80Acclaim! microcontroller family, with its built-in 10/100 Ethernet and FLASH memory, becomes a complete solution when combined with the CMX-MicroNet and CMX-RTX products."

CMX-MicroNet is a very small footprint TCP/IP software stack that has been developed to provide Internetworking connectivity tools to designers working with embedded processors, while the CMX-RTX is a fast RTOS targeting embedded applications that require an RTOS. Meanwhile, the CMX-Tiny+ is a reduced version of CMX-RTX that offers RTOS services for applications with limited ROM/RAM resources.

The eZ80F91 microcontroller from the eZ80Acclaim! Family of MCUs is based on the industry standard Z80 architecture. Featuring 50MHz operations and 16MB of linear memory addressing, the device has on-chip 10/100 Ethernet MAC and DMAs that handle network data packets efficiently. Overall system cost is reduced due to integration of 256KB of Flash memory and 16KB of RAM.

The Z8 Encore! microcontrollers include five configurations with up to 64KB (up to 512Kb) of high-speed Flash. Features include the 20MHz eZ8 CPU core, up to 4KB of linear register SRAM, and a comprehensive suite of peripherals including an on-chip DMA controller, up to 12 channels of 10-bit A/D, SPI, I2C, two 9-bit UART ports with integrated Infrared Data Association (IrDA)-compliant encoder/decoders, up to four 16-bit counter timers, and a single-pin, On-Chip Debugger.
