Introduction

AI Translation

The WL2405 is a single-chip wireless transceiver operating in the globally recognized 2.400~2.4836 GHz ISM band. The chip integrates functional modules including an RF transceiver, frequency synthesizer, crystal oscillator, and modem, and supports one-to-many networking and communication modes with ACK. Transmit output power, operating channel, and communication data rate are all configurable. Multiple peripheral passive components (resistors, capacitors, and inductors) have been integrated into the chip, facilitating FCC and other certifications.

Features

AI Translation
  • Operating voltage range: 2.0V~3.6V
  • 2Kx14 bits EPROM
  • 128 bytes SRAM
  • 8-level program stack
  • One 8-bit up counter Timer0 with programmable prescaler
  • Two 10-bit down counters (Timer1, Timer3) with selectable auto-reload or continuous count-down modes
  • 38/57KHz IR carrier frequency selectable; carrier polarity also selectable based on data
  • Built-in WDT with software-controlled enable/disable
  • Built-in POR circuit
  • Built-in LVR function
  • Built-in RFC function
  • Dual-clock mechanism with on-the-fly switching between high-speed and low-speed oscillation. High-speed oscillation: E_HXT (external high-speed crystal oscillation above 6MHz), E_XT (external crystal oscillation 455K~6MHz), I_HRC (internal high-speed RC oscillation 1~20MHz). Low-speed oscillation: E_LXT (external low-speed crystal oscillation 32KHz), I_LRC (internal low-speed RC oscillation 32KHz)
  • Eight hardware interrupts: Timer0 overflow, Timer1 borrow, Timer3 borrow, WDT, PA/PB input change-of-state, two external interrupt inputs, low-voltage detection
  • Low power consumption — TX mode (0dBm) operating current 13.7mA; RX mode operating current 12.3mA; sleep current 2uA
  • Excellent performance — RX sensitivity of -96.5 / -95 / -92 / -90dBm at 125K / 250K / 1M / 2M bps; maximum TX output power up to 8dBm; strong interference immunity with high adjacent channel rejection and excellent receiver selectivity; easy FCC and other certification compliance
