Description and Features
The RoHS-compliant series with internal Flash is dedicated to 2.4 GHz RF System-On-Chip solution, such as wireless mouse and wireless USB dongle. This SoC has hardware OTA upgrades support, allowing convenient product feature roll outs and upgrades. The SoC also includes a full range of on-chip peripherals for interfacing with external components such as LEDs, sensors, keyboards, and motors. This makes it an ideal single-chip solution for HID (Human Interface Devices) application. The SOC integrates a power-balanced 32-bit MCU, 2.4 GHz Radio, 32 KB (16K+16K) SRAM, 128 KB internal Flash, 14-bit ADC, 6-channel PWM (1-channel IR/IR FIFO/IR DMA FIFO), one quadrature decoder (QDEC), abundant and flexible GPIO interfaces, and nearly all the peripherals needed for 2.4 GHz RF System-On-Chip application development. The SoC also includes multi-stage power management design allowing ultra-low power operation and making it the ideal candidate for power-constraint applications. With the high integration level of 8355, few external components are needed to satisfy customers’ ultra low cost requirements.
