1. Description
ATA6285N and ATA6286N 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
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. 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 typi-
cally 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.
