ATA8201/ATA8202
UHF ASK/FSK Receiver
DATASHEET
Features
● Transparent RF receiver ICs for 315MHz (Atmel® ATA8201) and 433.92MHz
(Atmel ATA8202) with high receiving sensitivity
● Fully integrated PLL with low phase noise VCO, PLL, and loop filter
● High FSK/ASK sensitivity:
● –105dBm (Atmel ATA8201, FSK, 9.6Kbits/s, Manchester, BER 10-3
● –114dBm (Atmel ATA8201, ASK, 2.4Kbits/s, Manchester, BER 10-3)
● –104dBm (Atmel ATA8202, FSK, 9.6Kbits/s, Manchester, BER 10-3)
● –113dBm (Atmel ATA8202, ASK, 2.4Kbits/s, Manchester, BER 10-3)
● Supply current: 6.5mA in Active Mode (3V, 25°C, ASK Mode)
● Data rate: 1Kbit/s to 10Kbits/s Manchester ASK, 1Kbit/s to 20Kbits/s Manchester
FSK with four programmable bit rate ranges
● Switching between modulation types ASK/FSK and different data rates possible in
≤ 1ms typically, without hardware modification on board to allow different
modulation schemes
● Low standby current: 50µA at 3V, 25°C
● ASK/FSK receiver uses a low-IF architecture with high selectivity, blocking, and low
intermodulation (typical 3-dB blocking 68.0dBC at ±3MHz/74.0dBC at ±20.0MHz,
system I1dBCP = –31dBm/system IIP3 = –24dBm)
● Telegram pause up to 52ms supported in ASK Mode
● Wide bandwidth AGC to handle large out-of-band blockers above the system
I1dBCP
● 440-kHz IF frequency with 30-dB image rejection and 420-kHz IF bandwidth to
support PLL transmitters with standard crystals or SAW-based transmitters
● RSSI (received signal strength indicator) with output signal dynamic range of 65dB
● Low in-band sensitivity change of typically ±2.0dB within ±160-kHz center
frequency change in the complete temperature and supply voltage range
● Sophisticated threshold control and quasi-peak detector circuit in the data slicer
● Fast and stable XTO start-up circuit (> –1.4 kΩ worst-case start impedance)
● Clock generation for microcontroller
● ESD protection at all pins (±4kV HBM, ±200V MM, ±500V FCDM)

Conditions for the sensitivity measurement:
The given sensitivity values are valid for Manchester-modulated signals. For the sensitivity measurement the distance from
edge to edge must be evaluated. As can be seen in Figure 6-1 on page 21, in a Manchester-modulated data stream, the time
segments TEE and 2 × TEE occur.
To reach the specified sensitivity for the evaluation of TEE and 2 × TEE in the data stream, the following limits should be used
(TEE min, TEE max, 2 × TEE min, 2 × TEE max).
