- colechristensen 1y agoFrom the link >Espressif Systems (SSE: 688018.SH) announced ESP32-C5, the industry’s first RISC-V SoC that supports 2.4 GHz and 5 GHz dual-band Wi-Fi 6, along with Bluetooth 5 (LE) and IEEE 802.15.4 (Zigbee, Thread) connectivity. Today, we are glad to announce that ESP32-C5 is now in mass production.
- hughc 1y agoThis wording is ambiguous- it's the first to support 5GHz, but it's not their first RISC-V core.
- bobmcnamara 1y agoXtensa is a dead end, they said so on ESP32.com when someone pointed out the FPU ABI bottleneck
- platevoltage 1y agoI'm sure you're right. The current s3 chip is based on Xtensa, but it was released in 2020, so I guess the OP's statement is correct.
- bobmcnamara 1y agoEdit: dead end for espressif. Still gonna be in a bunch of DSPs and stuff
- snvzz 1y agoEspressif made a decisive shift to RISC-V[0], effectively abandoning Tensilica. ESP32-S3 was, AIUI, their last non RISC-V chip. It was announced in 2020 and released in 2022. 0. https://www.hackster.io/news/espressif-s-teo-swee-ann-confirms-a-shift-to-risc-v-by-default-unless-we-have-some-special-needs-5e365d49bcc5 https://www.hackster.io/news/espressif-s-teo-swee-ann-confir...
