The field-proven SiFive Essential family is already in use in billions of products including mobile phones, sensors, SSDs, FPGA platforms, surveillance cameras, smartwatches and more. The newest addition to the SiFive Essential family, SiFive Essential Gen4, brings higher performance, improved power efficiency and more flexible interfaces, with configuration and integration options to cover virtually any possibility.

To help customers manage power, performance, and area, the new generation of SiFive Essential products offers new code density extensions and advanced power management options. Additionally, SiFive Essential Gen4 supports WorldGuard, a fine-grain security model for isolated code execution and data protection.

SiFive Essential Gen4 is designed with flexibility in mind, enabling customers to choose whether to use a SiFive Essential Gen4 processor as a microcontroller in its own right (where it's the main processor in the system) or use it as a core alongside a different CPU. Additionally, SiFive Essential Gen4 offers support for AMBA ACE, a protocol for bidirectional data coherency that enables customers to create systems with multiple clusters of SiFive Essential processors.

The new generation of SiFive Essential products enables customers to tailor their designs and configure a processor that best fits the power, area, and performance for specific market requirements, ranging from the smallest area and power efficient 2-3 stage MCU up to a fully featured, superscalar, Linux-capable design, with all of the design points in between.
