The BC3602 is a high performance and low cost
FSK/GFSK transceiver for wireless applications
in the 315MHz, 433MHz, 470MHz, 868MHz and
915MHz frequency bands. It incorporates a highly in-
tegrated sub-1GHz transceiver and a baseband modem
with programmable data rates from 2Kbps to 250Kbps.
Data handling features include 64-byte TX/RX FIFO and
packet handling such as CRC generation, Forward Error
Correction, Data whitening and Manchester encoding.
@10dBm POUT
• High RX sensitivity (433.92MHz)
♦
-120dBm at 2Kbps on-air data rate
♦
-110dBm at 50Kbps on-air data rate
♦
-103dBm at 250Kbps on-air data rate
• High RX sensitivity (868.3MHz)
♦
-119dBm at 2Kbps on-air data rate
The BC3602 is optimized for the low power
consumption applications. At 433MHz band, its RX
mode is operated at 4.2mA and it delivers +10dBm
TX output power at 22mA current consumption.
A low-noise low-IF receiver can achieve -119dBm
sensitivity of 2Kbps data rate at 433/868MHz bands.
A Class-E Power Amplifier can deliver up to +13dBm
output power at 433/868MHz bands. A fully integrated
Fractional-N synthesizer can support a wide frequency
range with a fine resolution. Both loop filter and XO
load capacitors are integrared to on-chip to minimize
the requirement for external components.

-109dBm at 50Kbps on-air data rate
♦
-103dBm at 250Kbps on-air data rate
• On-chip VCO and Fractional-N synthesizer with
integrated loop filter
• Supports low cost 16MHz crystal with integrated
load capacitor
• Programmable digital channel filter for optimum
performance at various data rates
• AGC (Auto Gain Control) to achieve wide input
range, up to +10dBm
• AFC (Auto Frequency Compensation) for frequency
drift due to X’tal aging
External host MCU can access the BC3602 through
a 3-wire or 4-wire SPI interface. The device supports
short strobe commands to reduce the loading of the
host MCU while maintaining wireless communication
link.
• On-chip low power RC oscillator for WOR (Wake-
on-RX) and WOT (Wake-on-TX) functions
• Physical TX/RX FIFO buffers: TX 64 bytes,
RX 64 bytes
Additional link layer features like RSSI for channel
assessment, auto-acknowledgement and auto-resend,
WOT and WOR, etc., facilitate microcontroller based
ISM bands wireless link applications.
• Simple FIFO/Block FIFO/Extend FIFO
(up to 255 bytes)/Infinite FIFO modes
• Programmable threshold for carrier detection
• Frame synchronization recognition for both FIFO
mode and Direct mode
