The ATA6286C is a embedded ultra-low-power AVR 8-bit microcontroller ICs with integrated RF transmission and LF receiving functionality for wake-up purposes in a small QFN32 package. The RF transmission is based on well-known IPs for 432MHz to 448MHz frequency range with a typical output power up to 6dBm. They are suited for ASK and FSK modulation with up to 20Kbaud data rate in Manchester mode. The integrated programmable 125kHz LF receiver channel has extremely low current consumption in active listening mode. As a result, the LF receiver is particularly well suited for wake-up purposes. The programmable AVR 8-bit Flash microcontroller includes 8KB of in-system self-programmable Flash memory and 320 bytes of EEPROM thus allowing the system integrator to install field programmable firmware to meet flexible system requirements on different platforms. The ATA6286C is configurable to meet extremely low-power requests in sleep mode, measurement mode and transmission mode. The ATA6286Cis suited for powering single cell battery applications. Therefore, a single LiMnO2 battery coin cell can supply a whole system. The AVR 8-bit Flash microcontroller also delivers a dedicated integrated simple capacitive sensor interface, as well as an on-chip calibratable temperature sensor.
