This NXP evaluation board (including integrated debugger and available for around $49) is based on the MIMXRT1015DAF5A, which is the consumer version [0..95°C] of the 500MHz Cortex-M7 base part with double-precision VFPv5 FPU in 100 pin LQFP. It has 128k of internal RAM, high speed USB (with integrated PHY), 4 low power UARTs, 2 I2C controllers, 3 synchronous audio interfaces, 2 SPI interfaces, 1 FlexSPI interface (connected to 16MByte QSPI flash), 1 ADC, a True Random Number Generator, plus various other features.
The processor's budget price for 10'000 pieces is $1.48 (low quantity distributor price for 100 pieces under $4), potentially making it very attractive for low cost products requiring high processing performance, USB and audio.
A 24MHz crystal on the board allows for accurate generation of up to 500MHz processor and 480MHz USB clocks.
The µTasker target for the MIMXRT1015 allows immediate use of the board for various functions with simple control of performance/consumption as well as the ability to switch operation between this and other i.MX board/processors and Kinetis parts. Accurate simulation of the device in VisualStudio combined with integrated µTasker application functionality ensures reliable, low footprint product development solutions with minimum effort, risk and investment.
