The devices combine the functionality of the RF transmitter ICs ATA5756/ATA5757 with the programmable low-power AVR 8-bit Flash microcontroller in a single QFN32 package 5 mm x 5 mm . The ATA6285N and ATA6286N include a dedicated ADC interface for simple capacitive sensors as well as an on-chip temperature sensor. Three sensor interfaces are available for a capacitive range of 2 pF to 16 pF, where one channel can be configured as motion wake-up in the range of 3 pF to 5 pF. The ICs are suited for use in tire pressure monitoring TPMS sensor gauges in combination with external sensor devices. The programmable AVR 8-bit Flash microcontroller includes 8 Kbytes of in-system self-programmable Flash memory and an 320-Bytes EEPROM, thus allowing the system integrator to install field-programmable firmware to enable system flexibility on different platforms. ATA6285N and ATA6286N can be configured to guarantee extremely low power consumption in sleep mode and measurement mode. They also include a programmable 125 kHz wake-up receiver channel for extremely low current consumption in listening mode. The ICs are designed for use in applications with typically less then 10 passive components one external crystal for the sensor gauge, several capacitors, a single LiMnO2 battery coin cell, a single-ended antenna for the data transmission and an LF ferrite coil for the wake-up channel. ATA6285N and ATA6286N support TPMS-specific low-current modes even with an active brown-out detection and an interval timer.
