Atmel Simplifies Design-in Process with Introduction of New Easy-to-Use Transparent RF ASK Receiver for Wireless Data Control Applications.Business Editors/High-Tech Writers HEILBRONN, Germany--(BUSINESS WIRE)--March 26, 2002 Atmel(R) Corporation (Nasdaq:ATML ATML Automatic Test Markup Language ATML Automated Test Markup Language ) announced today the availability of a new RF data control receiver which is easy to use and thus simplifies design-ins. The receiver is transparent, which means that incoming data is directly forwarded to the output, the conventional first-time data validation and comparison is done by an external microcontroller as usual for consumer and industrial systems. The T5744 is an ASK (Amplitude Shift Keying) receiver and fits for almost all kinds of modulations schemes including Manchester, Biphase and most PWM (Pulse Width Modulation) A modulation technique that generates variable-width pulses to represent the amplitude of an analog input signal. Like its fixed-width pulse density modulation (PDM) cousin, the output switching transistor is on more of the time for a protocols. The new device targets industrial and consumer applications such as data transmission and remote keyless entry systems (garage door opener A garage door opener is a motorized device that opens and closes garage doors. Most are controlled by switches on the garage wall, as well as by remote controls carried in the garage owner's cars. or car opener, telemetering etc.), wireless entertainment devices like keyboards and mice as well as TV, VCR VCR: see videocassette recorder.

The T5744 operates in the frequency range of 300 MHz to 450 MHz and is designed for the demands of low-cost RF data communication systems with data rates of maximum 10 kHz. The device offers high sensitivity, especially at these low data rates.

To create a complete RF data communication system, the receiver IC seamlessly operates together with Atmel's RF PLL transmitters U274xB and T575x. As programming is not necessary, the circuit is easy to use in any application and design-ins can be realized quickly. The single-ended RF input allows unproblematic adaptation to a l/4 antenna or to a printed antenna on the board. Only a few external circuits and almost no RF components on the PC board are required. The replacement of currently used RF receivers by the T5744 is very simple, only two pins, the data pin and the standby pin, have to be connected to a microcontroller. To reduce the current consumption of 7 milliampere mil·li·am·pere n.

Samples of the new receiver IC T5744 in SO20 and SSO20 packages are available now, high-volume production is running. Pricing starts at US$1.39 (10k).
