General Description
♦ TX current consumption @ 868.3MHz: 24mA @ The BC3602 is a high performance and low cost 10dBm POUT FSK/GFSK transceiver for wireless applications • High RX sensitivity (433.92MHz) in the 315MHz, 433MHz, 470MHz, 868MHz and 915MHz frequency bands. It incorporates a highly in- ♦ -120dBm at 2Kbps on-air data rate tegrated sub-1GHz transceiver and a baseband modem ♦ -110dBm at 50Kbps on-air data rate with programmable data rates from 2Kbps to 250Kbps. ♦ -103dBm at 250Kbps on-air data rate Data handling features include 64-byte TX/RX FIFO and packet handling such as CRC generation, Forward Error • High RX sensitivity (868.3MHz) Correction, Data whitening and Manchester encoding. ♦ -119dBm at 2Kbps on-air data rate The BC3602 is optimized for the very low power ♦ -109dBm at 50Kbps on-air data rate consumption applications. At 433MHz band, its RX ♦ -103dBm at 250Kbps on-air data rate mode is operated at 4.2mA and it delivers +10dBm • On-chip VCO and Fractional-N synthesizer with TX output power at 22mA current consumption. integrated loop ilter A low-noise low-IF receiver can achieve -119dBm • Supports low cost 16MHz crystal with integrated sensitivity of 2Kbps data rate at 433/868MHz bands. load capacitor A Class-E Power Amplifier can deliver up to +13dBm output power at 433/868MHz bands. A fully integrated • Programmable digital channel filter for optimum Fractional-N synthesizer can support a wide frequency performance at various data rates range with a fine resolution. Both loop filter and XO • AGC (Auto Gain Control) to achieve wide input load capacitors are integrared to on-chip to minimize range, up to +10dBm the requirement for external components. • AFC (Auto Frequency Compensation) for frequency External host MCU can access the BC3602 through drift due to X’tal aging a 3-wire or 4-wire SPI interface. The device supports • On-chip low power RC oscillator for WOR (Wake- short strobe commands to reduce the loading of the on-RX) and WOT (Wake-on-TX) functions host MCU while maintaining wireless communication • Physical TX/RX FIFO buffers: TX 64 bytes, link. RX 64 bytes Additional link layer features like RSSI for channel • Simple FIFO/Block FIFO/Extend FIFO assessment, auto-acknowledgement and auto-resend, (up to 255 bytes)/In inite FIFO modes WOT and WOR, etc., facilitate microcontroller based • Programmable threshold for carrier detection ISM bands wireless link applications. • Frame synchronization recognition for both FIFO mode and Direct mode Rev. 1.00 1 July 29, 2019 Rev. 1.00 PB July 29, 2019 Document Outline Features General Description Block Diagram Pin Assignment Pin Description Absolute Maximum Ratings D.C.
