ATA5831/ATA5832/ATA5833

UHF ASK/FSK Transceiver

SUMMARY DATASHEET

Features

● AVR^®microcontroller core with 1Kbyte SRAM and 24Kbyte RF library in firmware

(ROM)

● Atmel^®ATA5831: 20Kbyte of user flash

● Atmel ATA5832: 20Kbyte of user ROM

● Atmel ATA5833: No user memory — RF library in firmware only

● Supported frequency ranges

● Low-band 310MHz to 318MHz, 418MHz to 477MHz

● High-band 836MHz to 956MHz

● 315.00MHz/433.92MHz/868.30MHz and 915.00MHz with one 24.305MHz crystal

● Low current consumption

● 9.8mA for RXMode (low-band), 1.2mA for 21ms cycle three-channel polling

● 9.4mA/13.8mA for TXMode (low-band, Pout = 6dBm/10dBm)

● Typical OFFMode current of 5nA (maximum 600nA at Vs = 3.6V and T = 85°C)

● Programmable output power –12dBm to +14.5dBm (0.4dB step)

● Supports the 0dBm class of ARIB STD-T96

● ASK shaping to reduce spectral bandwidth of modulated PA output signal

● Input 1dB compression point

● –48dBm (full sensitivity level)

● –20dBm (active antenna damping)

● Programmable channel frequency with fractional-N PLL

● 93Hz resolution for low-band

● 185Hz resolution for high-band

● FSK deviation ±0.375kHz to ±93kHz

● FSK sensitivity (Manchester coded) at 433.92MHz

● –108.5dBm at 20Kbit/s

● –111dBm at 10Kbit/s

● –114dBm at 5Kbit/s

f = ± 20kHz

f = ± 10kHz

f = ± 5kHz

BWIF = 165kHz
