Freescale Semiconductor powers ColdFire processors with new companion IC

To support the new ColdFire families, Freescale has developed a low-cost companion power management integrated circuit (IC), the MC34710.

MC34710 improves cost efficiency and development time for industrial control and network connectivity device designers

PHOENIX - May 17, 2004 - Freescale Semiconductor Inc., a wholly owned subsidiary of Motorola Inc. (NYSE:MOT), has developed an analog power management integrated circuit (IC) specifically designed to support its latest ColdFire® processor families.

The MC34710 supports numerous designs based on ColdFire technology and is ideal for embedded industrial and network control applications that need multiple voltages for the microprocessor and user circuitry, including point -of -sale terminals, network -attached storage, medical instrumentation and security/access control systems.

The device combines dual adjustable output voltages and built -in voltage sequencing to meet the power management needs of finer -geometry processors that require multiple operating voltages. With a high level of power management integration, the MC34710 has two regulators, supervisory capabilities and protection functions normally found in more expensive solutions. This helps minimize external circuitry, reducing board complexity and parts count.

Users can set voltages or alter them to reduce overall power dissipation under microprocessor control. This allows designers to move between ColdFire devices with differing voltages or to other microcontroller families without changing power supply design.

MC34710 Features
- 5V or 3.3V at 1A switching regulator
- 3.3V/2.5V/1.8V/1.5V @ 500mA low -noise linear regulator
- Integrated oscillator and charge pump circuitry
- On -chip thermal shutdown and error reset circuitry
- Start -up power sequencing, fault detection and system reset/POR capability
- Simple feature configuration via three package pins
- Low -cost 32 -pin thermally enhanced SOIC package

Price and Availability
Samples of the MC34710 power management IC are expected in July 2004. For limited sampling now, contact a Freescale representative. Suggested list price for 10,000 units is $1.35 (USD).
