NXP MCU Hits 1 GHz

Cluso99

Interesting little device. No internal Flash/NVRAM. 28nm.

i.MX RT1170 Crossover MCU Family - First Ghz MCU with Arm® Cortex®-M7 and Cortex-M4 Cores, 2MB internal SRAM.

A P2 at 28nm would slaughter it

Yes, interesting part... has a useful 2MB of on-chip SRAM, but in a BGA package.

Another interesting part is the 500MHz i.MX RT1010 - Flash-less, they call a low end part, sub $1 (in decent volumes) with a $10.10 eval board..

"The i.MX RT1010 MCU family is a low-cost,high-performance crossover MCU priced at sub-$1 (USD). In addition, starting
on 10/10/19, the MIMXRT1010-EVK will be available at a promotional price of $10.10 – for a limited time only."

Analog devices also offer 1GHz floating point DSPs 2000 MMAC 640 kB + 1024 kB SRAM
