Product Attributes

Introduction

The WL2800 series is a single-chip wireless transceiver operating in the 2.400 ~ 2.4836 GHz worldwide ISM band. The chip integrates an RF transceiver, frequency synthesizer, crystal oscillator, modem, and other functional modules, with support for one-to-many networking and ACK-based communication modes. Transmit output power, operating channel, and communication data rate are all configurable. Multiple peripheral passive components (resistors, capacitors, and inductors) have been integrated on-chip, facilitating FCC and other regulatory certifications.

Features

• Low power consumption: TX mode (0dBm) operating current 12.9mA; RX mode operating current 9.7mA; sleep current 1.53μA.
• Minimal external components: supports 4 peripheral components including 1 crystal oscillator and 3 SMD capacitors; supports dual-layer or single-layer PCB design with PCB microstrip antenna option; built-in partial link-layer communication protocol; minimal register configuration for ease of use.
• Excellent performance: RX sensitivity -96.5 / -95 / -92 / -90dBm at 125K / 250K / 1M / 2Mbps; maximum TX output power up to 13dBm; strong interference immunity, high adjacent channel rejection, excellent receiver selectivity, easy FCC and other certifications.
• 3-wire/4-wire SPI interface
• SPI interface rate up to 4Mbps
• Maximum data length 128 bytes (4-level FIFO)
• SOP8 package
• 1M / 2Mbps mode requires crystal accuracy ±40ppm & CL = 12pF; 125K / 250kbps mode requires crystal accuracy ±20ppm & CL = 12pF; BLE advertising packet mode requires crystal accuracy ±10ppm & CL = 12pF.
• Operating voltage: 1.7 ~ 3.6V
• Operating temperature: -40 ~ +125°C
