1. Description

ATA6285 and ATA6286 are highly integrated smart RF micro transmitter ICs for

315 MHz and 433 MHz, suited for ASK and FSK with typically 20 Kbits/s data rate in

Manchester mode. 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 × 5 mm). The ATA6285 and ATA6286 include a

dedicated ADC interface for simple capacitive sensors as well as an on-chip tempera-

ture 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 sys-

tem integrator to install field-programmable firmware to enable system flexibility on

different platforms. ATA6285 and ATA6286 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 consump-

tion 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. ATA6285 and ATA6286

support TPMS-specific low-current modes even with an active brown-out detection

and an interval timer.
