Nuvoton NT-M0564V Development Board
Testing the Nuvoton NuTiny-SDK-M0564 – development tool for the M0564 series microcontroller.
The M0564VG4AE is a Cortex-M0 microcontroller which can run at up to 72MHz, features 85 I/O pins, 256 KB Flash, 20 KB SRAM, 4KB ISP ROM and 2 KB SPROM(Security Protection ROM).
The 161 pages datasheet can be downloaded from here: http://www.nuvoton.com/resource-files/DS_M0564_Series_EN_Rev1.00.pdf
The whole Development Package can be downloaded from http://nuvoton.com/NuMicroDVD/
The archive contains some useful AppNotes, drivers for Keil and IAR, CooCox BSP, Datasheets and some useful stand-alone programs like ClockConfigure Tool, NuMicro PLL Generator Tool.
The next steps are: install and configure Keil, add packs, CMSIS… etc.
For Arduino Fans there is a NuMaker Uno Board based on NUC131 – another Cortex M0 ARM – https://direct.nuvoton.com/it/numaker-uno
The amazing small board – NXP LPC800 by NGX
The amazing small board – NXP LPC800
LPC800 series develeopment tool
I just get my hands on this board courtesy of Element14.
It’s amazing. Simple and efficient.
The small pin number is compensated in a great way: The Switch Matrix – it connects 6 pins to any available internal module.
Of course, programming can be done in bootloader mode, where every pin is reassigned according to the original layout.
LPC810 features:
- ARM Cortex-M0+
- Switch matrix for flexible configuration of each I/O pin function
- 2 USART interfaces, 1 SPI controller and 1 I²C-bus, with pin functions assigned through the switch matrix
- Self Wake-up Timer (WKT) clocked from either the IRC or a low-power, low-frequency internal oscillator
- CRC engine
- Boot ROM API support: boot loader, USART and I²C drivers in ROM, power profiles, Flash In-Application Programming (IAP) and In-System Programming (ISP)
The debugging options supported are SWD (10 pin connector), JTAG boundary scan and Micro Trace Buffer (MTB).
The quickest/cheapest programming method is via spi*ISP (6 pin connector) with a USB/Serial cable.

mbed – ARM Rapid Prototyping Tool
The mbed Comes in two flavors: CortexM3(NXP LPC1768) and CortexM0(NXP LPC11U24).
Here is the LPC1768 version, a 2×20 pin /2,54mm DIP board easy to use with breadboards.
- 1 ethernet port
- 3 serial ports (Rx/Tx)
- 2 SPI ports
- 2 I2C ports
- 6 Analog INs or 5 Analog INs + 1 Analog Out
- 1 CAN Port
- 6 PWM out
- 1 USB port (D+, D-) and the main USB-mini Port as a serial terminal
- 4 blue LEDs
Connected to USB shows up a 2MB FAT-FS storage with a preloaded web page which connects and autenthicates the user to the mbed.org website where resides the Free Online C Compiler and all other help pages, manuals, code examples, community contributed programs and libraries.
Loading a program is simple as drag-and-drop, you only need to drop the binary file on the MBED drive and the MBED Interface does all the programming after a board reset.

USER MANUALS: UM AND Getting Started
- Comment on U.S. Clings to Semiconductor Dominance as China Mounts Challenge by ubm112211 July 13, 2020In reply to IanD. usa seems , large amount of talents are in the software/internet corps. which left little can spare for semi dev. so even if US put some major investment in semis, it will end up with indian engs getting the benefit. that's one reason behind
- Comment on U.S. Clings to Semiconductor Dominance as China Mounts Challenge by ubm112211 July 13, 2020In reply to ubm112211. china is still in the process of getting it's 1st nand chip PRQed in year of 2020. nand was invented in 1991. which is a reflection of the efficiency of chinese system.
- Comment on U.S. Clings to Semiconductor Dominance as China Mounts Challenge by ubm112211 July 13, 2020luckily , the money spent by chinese , large amount of it getting wasted, by its in efficient system, lack of democracy , bureaucracy . so non of the system is perfect, just play to it's advantage. everyone got pressure though, no easy money in this world in the end.
