General Description

The TLSR8358F64/TLSR8358F512 is dedicated to 2.4GHz RF System-On-Chip solution, such as RF ID, private network, Beacon applications, etc.

The TLSR8358F64/TLSR8358F512 integrates a power-balanced 32-bit MCU, 2.4GHz Radio, 48kB SRAM, 64kB (TLSR8358F64) or 512kB (TLSR8358F512) internal Flash, a general-purpose ADC with PGA, 6-channel PWM (1-channel IR/IR FIFO), one quadrature decoder (QDEC), flexible GPIO interfaces, and nearly all the peripherals needed for 2.4GHz RF System-On-Chip application development.

The TLSR8358F64/TLSR8358F512 has hardware OTA upgrades support and multiple boot switching, allowing convenient product feature roll outs and upgrades. The TLSR8358F64/TLSR8358F512 also includes multi-stage power management design allowing ultra-low power operation and making it the ideal candidate for power-constraint applications.
