SiFive E2 Series Cores in ESP32-C3!

This looks pretty exciting.

CPU ESP32-C3 series is equipped with a low-power RISC-V 32-bit single-core processor with the following characteristics: • Four-stage pipeline architecture, supporting a clock frequency of 160MHz • RV32IMC ISA • Supporting 32-bit multipliers and 32-bit dividers • Supports up to 32 vectored interrupts with a total of 7 priority levels • Supports up to 8 hardware breakpoints/watch points • Supports up to 16 PMP areas • JTAG interface for debugging

Seems like 400 KB RAM, which is pretty handy for microcontroller kinds of things.

Can’t wait to get my hands on one. Bouffalo Labs also is standardizing with SiFive chips with BL70x and BL602.

Given it has an FPU, it must be the E24 core.
