+The SiFive E20 Standard Core is an extremely efficient implementation of the E2 Series configured for very low area and power. The E20 brings the power of the RISC-V software ecosystem to efficiently address traditional 8-bit and 32-bit microcontroller applications such as IoT, Analog Mixed Signal, and Programmable Finite State Machines.
+
+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 RV32IMC core
+- 4 hardware breakpoints
+- 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

+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
