Featured here is a low-cost, compact wireless transceiver module with SPI for embedded applications. The module comes with a 128-byte EEP ROM to save the data used for frequency calibration. It contains a 64-byte FIFO buffer, which can relieve the MCU's load while processing the data.

• Wireless RF module 315MHz/433MHz/470MHz/868MHz/915MHz ISM Band FSK module.
• Low cost and small size.
• Data rate: 250kbps.
• Transceiver is a compact surface-mounted half-duplex FSK module.
• It is a low-cost small-size wireless module with SPI for embedded applications.
• There is an external 128 bytes EEPROM to save the data used for frequency calibration.
• MCU will read the data in EEPROM After power-on to calibrate the frequency.
• It contains 64 byte FIFO buffer, which can relieve the MCU's load while processing the data.
• This makes it possible for a low-cost MCU to implement high-speed data transmission task.
• The RF data rate can reach 150kbps.
• The module with optional FEC , CRC and Manchester encoding can realize stable and reliable data transmission in busy ISM band.
• The module is completely shielded and designed for operation under the European and US radio regulations for license-free use.
• Main applications: intelligent home control system, wireless RFID tag.
• Wireless sensor, POS terminal, industrial data transmission, automatic data collection system, wireless remote control, wireless AMR for water, gas and hot, electricity and other meters.
