The datasheet says it's an ESP32. It also says that it's based on the Tensilica L106 CPU at up to 160MHz, while the ESP32 uses a Tensilica LX6 or LX7 (the ESP8266 is an L106) running up to 240MHz. It also has a block diagram that shows a RISC-V cpu.
So... I dunno. I don't think the datasheet is reliable
