EM358x

High-Performance, Integrated ZigBee/802.15.4 System-on-Chip Family

Silicon Labs

The Ember EM358x is a fully integrated System-on-Chip that integrates a 2.4GHz, IEEE 802.15.4-2003-compliant transceiver, 32-bit ARM® Cortex®-M3 microprocessor, flash and RAM memory, and peripherals of use to designers of ZigBee-based systems. The transceiver uses an efficient architecture that exceeds the dynamic range requirements imposed by the IEEE 802.15.4-2003 standard by over 15 dB. The integrated receive channel filtering allows for robust co-existence with other communication standards in the 2.4GHz spectrum, such as IEEE 802.11-2007 and Bluetooth. The integrated regulator, VCO, loop filter, and power amplifier keep the external component count low. An optional high performance radio mode (boost mode) is software-selectable to boost dynamic range. The integrated 32-bit ARM® Cortex®-M3 microprocessor is highly optimized for high performance, low power consumption, and efficient memory utilization.

Product Description

Including an integrated MPU, it supports two different modes of operation privileged mode and user mode. This architecture could allow for separation of the networking stack from the application code, and prevents unwanted modification of restricted areas of memory and registers resulting in increased stability and reliability of deployed solutions. The EM358x has either 256 or 512kB of embedded flash memory and either 32 or 64kB of integrated RAM for data and program storage. The Ember software for the EM358x employs an effective wear-leveling algorithm that optimizes the lifetime of the embedded flash. To maintain the strict timing requirements imposed by the ZigBee and IEEE 802.15.4-2003 standards, the EM358x integrates a number of MAC functions, AES128 encryption accelerator, and automatic CRC handling into the hardware. The MAC hardware handles automatic ACK transmission and reception, automatic backoff delay, and clear channel assessment for transmission, as well as automatic filtering of received packets. The Ember Packet Trace Interface is also integrated with the MAC, allowing complete, non-intrusive capture of all packets to and from the EM358x with Ember development tools. The EM358x offers a number of advanced power management features that enable long battery life. A high-frequency internal RC oscillator allows the processor core to begin code execution quickly upon waking. Various deep sleep modes are available with less than 2µA power consumption while retaining RAM contents. To support user-defined applications, on-chip peripherals include optional USB, UART, SPI, TWI, ADC, and general-purpose timers, as well as up to 24 GPIOs.
