ATA5831

In Production

Monolithic RF transceiver IC for the automotive and smart RF markets, providing industry's lowest power consumption, high sensitivity and high output power. Automotive applications include remote keyless entry (RKE), passive entry go (PEG), remote start (RS) and tire pressure monitoring (TPMS) systems. In addition, the ATA5831 is also suited for various Smart RF applications, for example, remote control systems such as garage door openers; or telemetering applications.
The device's superior RF functionalities (e.g., blocking capabilities, power management, and more) enable an extremely low current consumption. This permits to use smaller batteries to realize miniature designs, which is a key criteria for car key fob applications.
The RF transceiver IC provide high sensitivity at -123dBm (0.75kbit/s, FSK, Manchester code, at 433.92MHz) and -109dBm (at 20kbit/s, ASK, Manchester code, at 433.92MHz), respectively. The high output power of -12dBm to -14.5dBm is programmable in 0.4-dB steps. Both high sensitivity and high output power allow for extended RF transmission distances.
The ATA5831 combines RF functionality with a proven Microchip AVR® microcontroller core. Configuration via the EEPROM enables quick and seamless adaptation to the individual application needs. Programming is done via the SPI - even on-the-fly during operation.
The firmware is included in ROM, and the device provides additional Flash option for application-specific software needs.
