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 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 me...
