-The SiFive E21 Standard Core is a high-performance, full-featured embedded processor designed to address advanced microcontroller applications such as Sensor Fusion, Smart IoT, Wearables, Connected Toys, and more. Separate Instruction and Data Buses, along with 2 banks of Tightly Integrated Memory (TIMs) make the E21 an ideal choice for applications with deterministic or demanding memory requirements.

-This FPGA core target is ideal for makers and hobbyists to develop running application software building on top of freedom-metal libraries. The target supports:
-
-- 1 hart with RV32IMAC core
-- 4 hardware breakpoints
-- Physical Memory Protection with 4 regions
-- Up to 153 CLIC interrupt signals that can be connected to off core complex devices, with 16 levels
-- GPIO memory with 16 interrupt lines
-- SPI memory with 1 interrupt line
-- Serial port with 1 interrupt line
-- 4 RGB LEDS
-- 4 Buttons and 4 Switches
