The CV1800B in the Milk-V Duo looks very cool - but it's not an MCU.
According to the product page it actually even has an auxiliary MCU in it, in addition to its two high-performance processors.
- brucehoult 2y agoIt's a full-featured applications processor at MCU prices. Just compare it to the $23.80 Teensy 4.0 which has 1 MB RAM (vs 64 MB) and runs a Cortex M7 at 600 MHz. That is definitely an MCU. And, when it came out, very good value for money -- I love mine. But the $3 Duo blows it away in pretty much every way. If you want to talk about just the chip, the MIMXRT1062DVL6B in the Teensy goes for $14.48 qty 1, $9.17 qty 960. https://www.digikey.com/en/products/detail/nxp-usa-inc/MIMXRT1062DVL6B/13635843 https://www.digikey.com/en/products/detail/nxp-usa-inc/MIMXR... The CV1800B goes for $18 for 5 chips, $3.60 each. https://arace.tech/products/sophon-cv1800b-5pcs https://arace.tech/products/sophon-cv1800b-5pcs "can't be made economically with 64 bits [etc]". Yeah it can.
