DATA SHEET: SD3503 Target Applications Z-WAVE MODEM SOC Gateways TVs Set-Top Boxes USB sticks ITU-T G.9959 compliant devices (Short range narrowband digital radio- communication transceivers) Features QFN32 5x5 mm solution to run stack and application Low BOM 2.3 to 3.6 V operations 1 A sleep mode Maintain Z-Wave network presence within USB power-down mode current budget Radio Features The SD3503 modem SoC is designed for easy integration and time to Sensitivity -104dBm market. It is an ideal solution for Controllers in in applications such as TVs, Transmit power 5dBm Set Top Boxes, Gateways, and USB sticks. Z-Wave has a ten year track Z-Wave 9.6/40/100 kbit/s data rates record of backwards compatibility. SD3503 continues to build on this (actual use depends on region) legacy that enables all generations of Z-Wave to communicate seamlessly All Z-Wave sub-1GHz frequency bands in a Z-Wave Network. and protocols supported, currently The SD3503 Modem SoC is a Z-Wave Modem solution. Silicon Labs is spanning from 865.2 to 926 MHz providing the SD3503 firmware as binaries. The firmware exposes the well Multi-channel and RSSI listen before talk documented and proven Z-Wave Serial-API both on USB and UART. support (actual use depends on region) Microcontroller Features EEPROM Cycle optimized 8051 microcontroller SPI 128-bit AES security processor and hardware random number generator USB / UART FLASH, XRAM, 256 byte IRAM, 128 byte data-retention RAM, 256 byte data NVM Flash loader in ROM Cold start power up time in less than 1 ms Figure 1: Application example Programmable via USB, UART, Over-The-Air Firmware upgrades can be performed through UART or USB as new Battery monitor features become available in the future. Existing users of the Z-Wave Serial-API can easily upgrade to the SD3503 Modem SoC while reusing the host application. DSH12469-15 2/2018 1 Datasheet: SD3503 The SD3503 provides hardware-assisted frequency agility, enabling the module to switch away from a noisy channel without any communication overhead.

Due to its patented multi-channel support and excellent interference blocking performance, the SD3503 provides superior robustness. The Z-Wave system uses frequency agility, frame acknowledgement, retransmission, collision avoidance, frame checksum check, and sophisticated mesh routing for reliable full home coverage. Products based on the SD3503 are fully interoperable with existing Z-Wave solutions.
