Product description
BG337 is a high performance and low cost
Sub1GHz ISM band module wireless transceiver. This device integrates high speed
pipeline 8051 MCU, 16KBytes In-system programmable flash memory, 4KB SRAM,
various powerful functions and excellent performance of Sub1GHz GFSK/FSK
transceiver. BG337 has various operating modes, making it highly suited for
systems where ultra-low power consumption is required.BG337 has an 8bit ADC for
RSSI and 8 channel 12bit ADC for general purpose. Three kinds of serial
communication port (SPI, I2C and UART) can interact with other device(s).BG337 is one of AMICCOM sub1GHz family. It integrates AMICCOM sub1GHz transceiver well and offers a low cost solution with advanced radio features such as high output power amplifier up to 19 dBm (433MHz band, excluding LPF and HPF) and low noise receiver (-110dBm @50Kbps). Therefore, BG337 is very suitable for long LOS (line-of-sight) applications without the need to add an external LNA or PA.The on-chip data rate divider supports programmable on-air data rates from 2K to 250Kbps to satisfy different systemrequirements. For a battery powered system, BG337 supports fast settling time to reduce average power consumption.
