General Description
The BC3601 is a high performance and low cost CMOS
RF FSK/GFSK transceiver for wireless applications
in the 315MHz, 433MHz, 470MHz, 868MHz and
915MHz ISM (Industrial, Scientific and Medical)
frequency bands. It incorporates a baseband modem
with a programmable data rate from 2Kbps to 250Kbps.
Data handling features include 64-byte TX/RX
FIFO, packet handling, CRC generation, Forward
Error Correction and data whitening, Manshester
encoding.
The BC3601 supports short standby settling time,
X’tal settling time and on-chip regulator settling time
to meet low average power consumption requirements.
The integrated high performance 17dBm TX PA and
high sensitivity receiver make the device suitable for
long range wireless communication.
All critical RF function blocks are integrated in
the device to minimise the external component
requirements. The RF synthesizer contains a VCO
(Voltage Controlled Oscillator), an internal loop
filter and a low noise fractional-N PLL with high
channel frequency resolution. In the RX mode, two
IF (Intermedia Frequency)/complex bandpass filter
bandwidth combinations are selectable for optimum
performance between low and high (≥100K) data rate
applications.
External host MCU can access the BC3601 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.
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.
