My exposure to the __Nuvoton MS51 microcontroller__ came about due to its use in a number of Pimoroni Breakout Garden products, initially their [IO Expander|https://shop.pimoroni.com/products/io-expander] board, which provides 6 PWM/digital and 8 analog IO pins, and programmed via Python on a Raspberry Pi using a single I2C connection. Very handy.
Back in October 2020 I sent a [message|https://forums.pimoroni.com/t/development-using-the-nuvoton-ms51/15182/2] into the Pimoroni forum regarding the use of the [Nuvoton MS51 microcontroller|https://www.nuvoton.com/export/resource-files/TRM_MS51_16KBFlash_Series_EN_Rev1.03.pdf] on their [IO Expander Breakout Garden board|https://shop.pimoroni.com/products/io-expander]. The MS51 is an [MCS-51/8051-compatible|https://en.wikipedia.org/wiki/Intel_MCS-51] microcontroller, using the same 1980s-era 8 bit architecture.

A bit later Pimoroni released a pair of RGB LED knob controllers, a [RGB Encoder|https://shop.pimoroni.com/products/rgb-encoder-breakout] and [RGB Potentiometer|https://shop.pimoroni.com/products/rgb-potentiometer-breakout] that internally use the MS51. Recently they even added a tiny [Super Dinky Blinky|https://shop.pimoroni.com/products/super-dinky-blinky] LED blinker board that uses it, even providing github links and instructions on how to hack/reprogram the device. So it's clear Pimoroni have some engineers on staff who like the MS51 as a general-purpose controller.

I've also contacted their sales department to see about the price for purchase of the IAR IDE for a quantity of one. The installer included a "dongle driver" so I'm hoping they don't use dongle-based license management (yuck). At least for the trial license there's no dongle. If the commercial price of the KEIL IDE ($395) is any indication, the IAR one might be rather expensive. I hope to get a quote from their sales rep, otherwise I'll be limited to 4K code files.
