Silicon Labs SD3502A-CNE3

Overview

The SD3502 is a general purpose Z-Wave® SoC with built-in microcontroller, making it ideal for single microcontroller products such as Thermostats, Door Locks, Light Dimmers, Remote controls and Sensors.Z-Wave has a ten year track record of backwards compatibility. SD3502 continues to build on this legacy that enables all generations of Z-Wave to communicate seamlessly in a Z-Wave Network.The SD3502 SoC addresses the need for increasingly user friendly and feature rich Home Control applications by introducing 128kB Flash and 16kB SRAM. Even complex applications using Secure Z-Wave® such as Door Locks can be fully contained in the SD3502, creating a very cost effective solution.The built in Key-scan and Infrared controllers are ideal building blocks for designing a Universal Remote Control supporting both learning and sending IR codes as well as Z-Wave commands.SD3502 provides hardware assisted frequency agility, enabling the chip to switch away from a noisy channel without any communication overhead.A low sleep current and hardware support for an ITU-T G.9959 compliant Frequently Listening (FL) sensor mode extends battery lifetimes and allows existing Z-Wave® products to experience up to double battery lifetime when switching to SD3502.Target Applications:• Thermostats• Locks• Light Dimmers• Sensors• Remote Controls• Smart Meters• Any ITU-T G.9959 compliant devices(Short range, narrowband, digital radio-communication transceivers)Radio Features:• Sensitivity -104dBm• Transmit power 5dBm• Z-Wave® 9.6/40/100 kbit/s data rates (actual use depends on region)• All Z-Wave® sub-1GHz frequency bands and protocols supported, currently spanning from 865.2 to 926 MHz• Multi-channel and RSSI listen before talk support (actual use depends on region)• External PA support for +20dBmMicrocontroller Features:• Cycle optimized 8051 microcontroller• 128-bit AES security processor and hardware random number generator• Memory for Z-Wave® stack and user applications: 128k byte FLASH, 16k byte XRAM, 128 byte IRAM, 256 byte dataretention RAM, 256 byte data NVM• Flash loader in ROM• Sleep mode 1 μA, Wake-up Timer + 700nA (typical) Bostock Electronics is an authorized Silicon Labs distributor.
