DATA SHEET: SD3502 Target Applications GENERAL PURPOSE Z-WAVE WIRELESS MICROCONTROLLER Thermostats Locks Light Dimmers Sensors Remote Controls Smart Meters Any ITU-T G.9959 compliant devices (Short range, narrowband, digital radio- communication transceivers) Features Single chip solution to run stack and application Low BOM The SD3502 is a general purpose Z-Wave SoC with built-in SD3402 pin and SW compatible microcontroller, making it ideal for single microcontroller products such as 2.3 to 3.6 V battery operations Thermostats, Door Locks, Light Dimmers, Remote controls and Sensors. Low power: sleep current 1 A Low power: Frequently listening slaves Z-Wave has a ten year track record of backwards compatibility. SD3502 (FLIRS) network node consumes 44 A continues to build on this legacy that enables all generations of Z-Wave to 2ch, 76 A 3ch communicate seamlessly in a Z-Wave Network. Radio Features The SD3502 SoC addresses the need for increasingly user friendly and feature rich Home Control applications by introducing 128kB Flash and Sensitivity -104dBm 16kB SRAM. Even complex applications using Secure Z-Wave such as Transmit power 5dBm Door Locks can be fully contained in the SD3502, creating a very cost Z-Wave 9.6/40/100 kbit/s data rates effective solution. (actual use depends on region) The built in Key-scan and Infrared controllers are ideal building blocks for All Z-Wave sub-1GHz frequency bands designing a Universal Remote Control supporting both learning and and protocols supported, currently sending IR codes as well as Z-Wave commands. spanning from 865.2 to 926 MHz Multi-channel and RSSI listen before talk SD3502 provides hardware assisted frequency agility, enabling the chip to support (actual use depends on region) switch away from a noisy channel without any communication overhead. External PA support for +20dBm A low sleep current and hardware support for an ITU-T G.9959 compliant Microcontroller Features Frequently Listening (FL) sensor mode extends battery lifetimes and allows existing Z-Wave products to experience up to double battery lifetime Cycle optimized 8051 microcontroller when switching to SD3502. 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 data- retention RAM, 256 byte data NVM Flash loader in ROM Sleep mode 1 A, Wake-up Timer + 700nA (typical) DSH12206-13 1/2018 1 Datasheet: SD3502 Cold start power up time in less than 1 ms Programmable via USB, UART, SPI, Over-The-Air 23 GPIOs, USB 2.0, UART, SPI 4 channel 12 bit rail-to-rail ADC 88-key matrix scan hardware Dimmer and PWM generators IR code generator and learning HW 4 channel LED PWM generator S D 35 02 Z - W A V E Q FN 48 W I R E L E S S M I C R OC ON TR OLL E R Brown Out Power On ADC Reset Reset 128kB Wake Up 12kB XRAM 4kB XRAM Flash Memory Timer 128B XRAM Timer 0/1 System Clock (persistent) IR code 4ch LED Interrupt AES 256B IRAM SFR gen/learn PWM Controller Z-Wave Wireless Transceiver GP Timer / Power Frame PWM Control Handler 8051 CPU Core Slow Timer Dimmer Watchdog 256BData Phy Timer 3ch RF FLIRS SPI M/S USB 2.0 NVM Key-pad Sys Tic Timer UART I/O Interfaces Scanner Figure 1: Architecture (kB=1024 byte) DESCRIPTION The SD3502 Z-Wave chip is a complete wireless solution for applications in home control, home security monitoring, home energy management, and AV control, consisting of an integrated multi-band, multi-channel, multi-speed RF transceiver, an 8051 microcontroller, a comprehensive set of peripherals, SRAM, 128k-byte FLASH, and data-NVM memory for sharing between a user application and the Z-Wave protocol. Thanks to its patented multi-channel support and excellent interference blocking performance, the SD3502 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 SD3502 are fully interoperable with existing Z-Wave solutions. 2 DSH12206-13 1/2018
