As one member of the low-power, high-integration family of Telink wireless SoC solution, the TLSR8368 is dedicated to 2.4GHz RF System-On-Chip solution, such as wireless keyboard, non-audio remote control applications, etc.

The TLSR8368 integrates an advanced 2.4GHz RF transceiver, a powerful 32-bit MCU, 16KB on-chip OTP, 6KB on-chip SRAM, a 10bit ADC, a quadrature decoder (QDEC), four-channel PWM, abundant I/O interfaces, and nearly all of the peripheral blocks needed to construct a powerful 2.4GHz RF System-On-Chip solution. Few external components are needed to satisfy customers’ ultra-low cost requirements.

The TLSR8368 is RoHS-compliant and 100% lead (Pb)-free.
