General Description
The TLSR8266/TLSR8266F512/TLSR8266F128/TLSR8266F1K is Telink-developed BLE SoC
solution which is fully standard compliant and allows easy connectivity with Bluetooth Smart
Ready mobile phones, tablets, laptops. Telink BLE SoC supports BLE slave and master mode
operation, including broadcast, encryption, connection updates, and channel map updates.
It is RoHS-compliant and 100% lead (Pb)-free.
The TLSR8266/TLSR8266F512/TLSR8266F128/TLSR8266F1K is designed to offer high
integration, ultra-low power application capabilities. It integrates strong 32-bit MCU,
BLE/2.4GHz Radio, 16kB SRAM, 128/256/512kB external FLASH (TLSR8266) or 512kB internal
Flash (TLSR8266F512) or 128kB internal Flash (TLSR8266F128) or 1024kB internal Flash
(TLSR8266F1K), 14bit ADC with PGA, 6-channel PWM, three quadrature decoders, a
hardware keyboard scanner (Keyscan), abundant GPIO interfaces, multi-stage power
management module and nearly all the peripherals needed for Bluetooth Low Energy
applications development.
