Atmel Announces a Low Cost RF Wireless System Chip Set Targeted at the High-Growth UHF Unlicensed ISM Band
SAN JOSE, Calif.--(BUSINESS WIRE)--Dec. 16, 2002--
Two-Chip Solution Yields Complete 2-Way Radio Frequency System:
Transmitter, Receiver and Microcomputer
Atmel(R) Corp. (Nasdaq:ATML) announced today the availability of a
UHF RF wireless on/off key transceiver chip set based on Atmel's
AT86RF401 Smart RF microtransmitter and its T5744 receiver. The
microtransmitter's powerful AVR(R)-based core enables it to be paired
with the T5744 receiver and supervise 2-way on/off keyed
communications in the unlicensed ISM band (300MHz - 450MHz). Both
chips minimize external component count through high levels of
integration. As a result, with +6dB of output power on the
microtransmitter and -110dB of input sensitivity on the receiver, a
high performance, low-cost, 2-way RF wireless system can be realized.
These features make this chip set ideally suited for low-cost,
low-data rate, 2-way remote sensing applications, such as temperature,
pressure, and motion as well as remote control applications, like home
appliance and lighting, energy management and monitoring, and security
systems.
Jim Goings, Atmel's Smart RF Marketing and Applications Manager,
pointed out, "The AT86RF401 Smart RF microtransmitter has a relatively
unknown but powerful design attribute that allows its interrupt-based
bit timer to encode serial data on the RF carrier during transmission
as well as decode demodulated serial data from the receiver. Anytime
you can get two features for the price of one, you're adding value for
your customer."
The AT86RF401 Smart RF microtransmitter contains an AVR
microcomputer with 2KB of Flash program memory and 128B of EEPROM data
memory. Its Flash can be updated easily and quickly with the
customer's software anytime before, during or after the assembly
process, using its built-in In System Programmability (ISP)
capabilities. This eliminates costly obsolescence associated with
masked ROM solutions and moves the product to market swiftly.
The microtransmitter's integrated PLL-based RF transmitter is
intricately linked to the AVR microcomputer core. This places many key
RF parameters, including VCO tuning, output power, and carrier
modulation, under software control. Control and flexibility like this
enables the user to quickly and easily optimize a design.
The T5744 receiver offers high sensitivity at data rates to 10KHz
and has an integrated Received Signal Strength Indicator (RSSI) output
to enable signal strength determination of the received signals. Its
architecture supports all kinds of modulation schemes, including
Manchester, Biphase and most Pulse Width Modulation (PWM) protocols.
The chip set is available now and is intended to minimize PCB area
with space saving TSSOP20 (TX) and SO20/SSO20 (RX) packages. Chip set
pricing starts at $3.23 per pair in quantities of 10,000 units.
An evaluation kit featuring a fully operational system including a
receiver board and transmitter board, samples of the AT86RF401 and
T5744 chip set, and the necessary tools to enable the development of a
2-way RF wireless system is available now. The kit can be ordered by
contacting any Atmel distributor. Reference part number
ATAK4015744U/E, where the U suffix indicates a 315MHz system and the E
suffix indicates a 433.92MHz system. The kit sells for $279.
