Atmel Introduces New Low-Current RF Remote Control Receiver with Industry's Highest Functionality.Business Editors/High Tech Writers HEILBRONN, Germany--(BUSINESS WIRE)--Jan. 8, 2002 Atmel(R) Corporation (Nasdaq: ATML ATML Automatic Test Markup Language ATML Automated Test Markup Language ) announced today the new RF remote control receiver T5743N for keyless-entry, telemetering and security systems. This receiver IC is the only product on the market with such a combination of various functions. The T5743N is a multi-chip PLL PLL - phase-locked loop receiver device with fully integrated VCO (1) (Voltage Controlled Oscillator) An oscillator that can be tuned over a wide range of frequencies by applying a voltage (tuning voltage) to it. Used in many applications such as radio tuners, VCOs are less costly than crystal oscillators, but not as stable. , especially developed for the demands of RF low-cost data transmission systems with data rates from 1 kBaud to 10 kBaud in Manchester or Bi-phase code. It can be used for both Amplitude Shift Keying (ASK) and Frequency Shift Keying (FSK (Frequency Shift Keying) A simple digital modulation technique that uses two frequencies for 0 and 1. See frequency modulation. ) systems. The receiver is fully compatible with Atmel's range of PLL RF transmitters. The receiver's current consumption is extremely low due to its programmable self-polling and timeframe check function. In contrast to other solutions, the current consumption is less than 1 mA not only for the receiver but even for the overall system including the microcontroller. This can be achieved as due to the self-polling mode, the microcontroller does not need to wake up for monitoring if a correct signal comes in. During sleep mode, the crystal oscillator An oscillator that uses a quartz crystal to generate a frequency. Such devices generally output a fixed frequency, but some can be controlled by a tuning voltage over a small range. Contrast with VCO. continues operating with very little power (typically 200 microampere microampere Cardiology A unit of electric current—one millionth of an ampere–for measuring very small electric currents; most pacemakers draw 10–30 µAmp continuously from a battery at 25 degrees C/ 5 V). The T5743N provides several functions that make the use of the end product more comfortable. A data clock signal is available to enable easy decoding. Furthermore, an IC-condition indicator (sleep or active) for controlling the preamplifier Preamplifier A voltage amplifier suitable for operation with a low-level input signal. It is intended to be connected to another amplifier with a higher input level. is on chip. Sensitivity reduction is possible even while receiving. The 5-V to 20-V data interface bridges longer signal transmission distances, for example, if the antenna is located at the rear window of a car. "We are excited to present manufacturers a new, highly sophisticated device that will enable them to integrate many comfort functions into keyless-entry, telemetering and security systems while still serving the most important need of these applications - low power consumption," said Torsten Mann, Atmel's Marketing Director for Automotive Products. Samples of the T5743N in SO20 packages are available now. They can be delivered in tube or taped and reeled. Pricing starts at $1.98 (10 k).
