Freescale expands ColdFire microcontroller line-up
31 October 2007
DSP, Micros & Memory
Freescale has added 10 highly integrated microcontrollers (MCUs) to its extensive 32-bit ColdFire portfolio. These latest ColdFire additions provide developers with a range of cost-effective, low-power connectivity options, coupled with comprehensive software tools.
Four Ethernet-enabled devices have been added to the MCF5223x family, giving developers more performance options. These Ethernet MCUs feature an on-chip Ethernet controller with a 10/100 Ethernet PHY. By embedding the Ethernet PHY on chip, designers can lower system cost, save board space and reduce the number of components in their design. Freescale is supporting the Ethernet MCU family with comprehensive software solutions, including a complementary RFC-compliant TCP/IP stack that supports a wide range of protocols.
Four USB-enabled devices have been added to the MCF5221x family, giving designers more memory and performance options. The on-chip USB on-the-go (OTG) module featured throughout the device family gives designers the option of using the module in USB device or host modes. The MCF5221x family also integrates USB transceivers on-chip, eliminating the need for an external component and simplifying system design. This family has a 6 μA current draw in standby mode and 10 μA current draw in low-power run mode. Freescale is supporting the USB MCU family with comprehensive software solutions, including a complementary USB stack that enables USB host and device modes of operation. The USB stack also supports several HID, CDC to UART, and host mass storage projects, and interfaces directly to CodeWarrior Development Studio.
Lastly, two 32-bit devices have been added to the recently announced Flexis QE family, providing developers with more memory options. Based on the V1 ColdFire core, the two MCF51QE32 devices provide ultra-low-power solutions for power-sensitive applications, such as battery-powered systems and portable devices. Drawing 370 nA of current in the lowest power stop mode, these latest QE devices are designed to reduce power consumption and heat dissipation and address the growing market for energy-efficient 'green' products. These latest MCF51QE32 devices are pin-for-pin compatible with the rest of the Flexis QE devices, providing an easy migration path to higher memory densities.
