ATA5785

The ATA5785 is a non-EEPROM version of the ATA5781. The ATA5785 is a monolithic RF receiver IC for the automotive and smart RF markets, providing industry's lowest power consumption and high sensitivity. Automotive applications include remote keyless entry (RKE), passive entry passive start (PEPS), remote start (RS) and tire pressure monitoring (TPMS) systems. In addition, the ATA5785 is also suited for various smart RF applications, for example, remote control systems such as garage door openers or telemetering applications.

The RF receiver IC provide high sensitivity at -122.5dBm typ. (0.75Kbit/s, FSK, Manchester code, at 433.92MHz) and -125dBm typ. (at 0.5Kbit/s, ASK, Manchester code, at 433.92MHz), respectively.

The ATA5785 achieves low power consumption through its superior blocking capabilities, which eliminate disturbances. With few disturbances, the digital logic is rarely awakened, resulting in a current consumption as low as 9.8mA typ. in receive mode (low-band, 310-318MHz, 418-477MHz, 1.2mA, 21ms cycle, 3-channel polling).

The ATA5785 combines RF functionality with a proven Microchip AVR® microcontroller core.

The ATA5785 is a ready-to-use version with integrated firmware.
