Cambridge-based Cyan Technology is shipping its latest family of low-power, feature-rich MCUsthe eCOG1X. With this latest product offering, Cyan says it is able to address new and more demanding applications including ePOS, telematics, security, access control, pay phones, consumer, motor control and networking.

According to the company, the eCOG1X MCUs are highly configurable, with options including combinations of USB 2.0 OTG, 10/100 Ethernet MAC and analog I/O. Each combination is available with different onboard memory options, with up to 512Kbytes of on-chip flash and 24Kbytes of SRAM. The 16bit, 70MHz devices also offer 42MIPS processing performance, tripling that of current eCOG1k devices.

Configurable peripherals
All Cyan MCUs offer reconfigurable and flexible peripherals. Using CyanIDE, the company's free development tool, designers can set up peripherals with little or no programming effort and link them to device pins that best suit the application. The latest release of CyanIDE, version 1.4, includes full support for the eCOG1X family whose new combinations of peripherals and higher core performance fulfill the requirements of more challenging applications.

"The 16bit eCOG1X has capabilities comparable to many 32bit MCUs for embedded communications, but is easier to use, features lower power consumption and requires considerably less development time," said Paul Barwick, Cyan's sales director. "The eCOG1X also has a significant USB capability. With minimal external components, the device is able to act as a USB 2.0 full-speed (12Mbps) device in host, peripheral or OTG modes. High-speed (480Mbps) data rates can also be achieved by adding a low-cost external ULPI PHY. The eCOG1X is the only 16bit MCU on the market today that can achieve this combination of USB modes and data rates."

The new MCU family also has a new analog section including two flexible 12bit DACs with a 4?s settling time; an LCD controller with support for direct and multiplexed drive of 1 to 4 backplane lines; and, the eICE built-in emulator that can program the internal flash. For motor control applications, there are dual ADCs that can simultaneously sample voltage and current analog inputs with between 6bits and 12bits resolution; and for three-phase motors there is a dedicated six-channel PWM timer function. With a fully configurable MMU and vectored interrupt modes, developers can have the real-time responsiveness needed for today's more demanding embedded applications.

Package options
The packages available include 68- and 100-pin QFN and 208-pin BGA, with further packages and options to be introduced throughout 2007. A comprehensive development environment is available along with a new release of CyanIDE. The unit selling price for eCOG1X products ranges from $4 to $10 in quantities of 10,000.

Cyan will showcase its latest MCU offerings at the International IC-China Conference & Exhibition in March.
