AT73C209 Analog Companion power supply and audio interface IC designed for low-cost music players. The AT73C209 supplies the required voltages and currents to all the sections of these portable devices taking energy from a single alkaline battery, and also provides a high-quality audio interface.

The AT73C209 integrates power management and high-quality audio circuitry on a single chip. It has 2 linear regulators (LDO) and one very low input voltage and high-efficiency Step Up switching regulator (DC-DC) working down to 0.9V, thus particularly suited for 1 cell Alkaline/NiMh batteries. On the audio side, the AT73C209 offers an audio-quality 16-bit Stereo Audio DAC with headset driver and microphone preamplifier to interface with the recording stage of a MCU.

"The AT73C209 introduction confirms Atmel's strategy to provide analog companions for generic handheld applications," commented Michele Casetta, Marketing Manager for Atmel's Power Management and Analog Companions (PMAAC) Product Line. "The AT73C209 is one of the few ICs on the market that integrates 3-channel power supplies and a high-quality audio interface for music players. The AT73C209 is the first device on the market that can be supplied with a 1-cell Alkaline/NiMh battery or USB port, with automatic switch, and manage all the rest of the system."

"The AT73C209 can minimize the BOM by reducing the component count to only 3 ICs: (MCU + Memory + AT73C209). In the past the system consisted of at least 8 components due to the number of discrete analog devices," concluded Michele Casetta.

Availability and Pricing

Atmel offers the AT73C209 in a 7 x 7 mm, 32-pin QFN package in order to satisfy portable device manufacturers' minimum space requirements and low cost. The AT73C209 is priced at US$1.30 in quantities of 100K units. It is available now mounted on a reference design board or as engineering samples.

The DAC7714 is a quad, serial input, 12-bit, voltage output Digital-to-Analog Converter (DAC) with guaranteed 12-bit monotonic performance over the –40°C to +85°C temperature range. An asynchronous reset clears all registers to either mid-scale (800_H) or zero-scale (000_H), selectable via the RESETSEL pin. The device can be powered from a single +15V supply or from dual +15V and –15V supplies.

Low power and small size makes the DAC7714 ideal for process control, data acquisition systems, and closed-loop servo-control. The device is available in a SO-16 package, and is guaranteed over the –40°C to +85°C temperature range.

Prodigy^® Motion Control Card improves application flexibility with powerful new feature set including direct amplifier commutation signals for multi-axis and multiple motor types.

Lincoln, MA — The Prodigy^® Motion Cards from Performance Motion Devices, Inc. (PMD), designed with PMD's advanced Magellan™ Motion Control IC, provide board level, multi-axis motion control for DC brush, brushless DC, step, and microstepping motors. In addition to trace capture, Prodigy cards provide advanced motion control features including trajectory generation, servo loop closure, quadrature signal input, motor output signal generation, on-the-fly changes, commutation, and much more.

Key Updated Features Include...

• 4 axes motor control with direct amplifier commutation signals for brushless DC and microstepping motors, allowing the designers to use lower cost amplifiers.
  

• Servo loop rates of up to 50 µSec/Axis (20 kHz).
• Quadrature encoder rates up to 8 Mcount/Sec.

Prodigy cards are available in PCI and PC/104 configurations, and provide 1, 2, 3, or 4 axes of control. Prodigy-PCI and Prodigy-PC/104 utilize high density logic circuitry to provide cost-effective, advanced motion control functions programmed in C/C++ or Visual Basic language. The cards accept input parameters such as position, velocity, acceleration, and jerk from the host, and generate a corresponding trajectory. Instantaneous on-the-fly changes can be sent by the user, and external signal inputs can be used to program automatic profile changes.

Prodigy-PCI and Prodigy-PC/104 are available now. Prices start at $380 in OEM quantities.

Features:

• Uses PMD's advanced Magellan Motion Control IC
