Beijing, September 12, 2013 - Leaders at the Global Microcontroller and Touch Solutions (NASDAQ: ATML) today announced the launch of special designs designed for automobile and intelligent radiofrequency (RF) market New series low power consumption, high performance RF receiver.
With the lowest power consumption, high sensitivity and excellent band-exterior obstruction performance, three new equipment (ATA5781, ATA5782 and ATA5783) will become ideal for many automotive applications, including: remote control keyless access control (RKE ), Passive Gate Prohibition System (PEG) / Passive Access Control, Passive Start System (PEPS), Remote Start System (RS), and Tire Monitoring System (TPMS). In addition, the new RF receiver series can also perfectly match a wide range of intelligent RF applications, including various types of remote control systems such as garage doorholders or telemetry applications.
ATA5781, ATA5782 and ATA5783 The power consumption in the reception mode is only 9.8mA, while the power consumption of the same product is 12mA. The reduction in power consumption can reduce the battery power consumption, thereby extending the battery life when the parking and receiver is turned on. These devices have extremely high sensitivity, when IFBW (medium bandwidth) is set to its lowest value 25kHz, the sensitivity is typical to -122.5 dBm. This can extend the role of RF communication.
RF blocking performance is an indicator of evaluating the anti-interference capability of the receiver. The interference source often appears in the wild. The ATA578X series excellent obstruction performance can greatly reduce the false wake up of strong electricity. In addition, they can also prevent shortening and communication failures of RF action from RF interference sources.
These new devices provide a dual path to support FSK and ASK reception by combining RF functions, a advanced state machine and an Atmel AVR® microcontroller core, providing a dual path to the FSK and ASK reception, and has extremely flexible. Customers can quickly configure up to 5 services including RKE, RS, PEPS, and TPMS in idle mode via SPI (Serial Extreme Interface). Therefore, customers no longer need to operate in the production site, thereby helping to save production time and cost. Dual Path Receive features and flexibility allow customer to adjust the receiver for behavior of each application. Customers can optimize power consumption because they can adjust the polling scheme as needed. If you need to adjust for specific customers, the designer can add an existing firmware with Flash (ATA5782) or User ROM (ATA5783).
The new RF receiver series includes:
• ATA5781: Integrated firmware, Alteration of RF receiver ICs available
• ATA5782: The firmware is built into the read-only memory (ROM). The Flash option is used to meet the software requirements of the specific application.
• ATA5783: ATA5782 cost optimization version, customer software is hidden in the ROM.
Atmel's RF combinations include receivers and transceivers (ATA5831 / 32/33), which have compatibility in terms of pins, functions, and RF matching, ensuring maximum reuse in the development of one-way and two-way systems. This reduces the workload of system designers. In order to further reduce the complexity of development and production work, shorten the product's listing time, and the terminal application engineer can use the same printed circuit board design in one-way and two-way automobile access control systems.
Supply information
The ATMEL ATA5781, ATA5782 and ATA5783 samples were started with 5mm x 5mm QFN32, and the price was now available for $ 1.90 (50,000 pieces). The automotive access tool bag (ATAK51003-V1) used to provide design support and shortening the product is also started.
