They are the defacto standard micros used in motor control and automotive applications.
Renesas flash development toolkit 4.09 code#
The Appliet tool (pin/peripheral generator) is nice but the resultant code that is generates is horrid and is only good for a “get running quick” demo. We also use the RL78 line a lot, but only the CC-RL compiler is good. I cannot comment on the RA or Synergy lines. Now it is trivial to setup a project and get running, even a FreeRTOS version. However, they have finally combined the Smart Configurator (pin/ peripheral setup) tool and the FIT modules (driver/library code). Their chips are very flexible which makes them complex to setup (setting up a “simple” DMA transaction is anything but simple).

Our biggest grip was their chip configuration and driver code tools. Also the new emulators (E2 lite) are much more affordable than what was previously offered. Their homegrown CC-RX compiler is very good and is free with memory restrictions. They’ve really stepped up their game in the last couple years. INL might not be too important in many applications but they do call this part a 'Precision Analog Microcontroller'. This is especially bad as INL at these levels is very hard to measure especially if you don't have the design details of the ADC. to determine the worst case numbers and the typical values given there's a very good chance that you won't be using a PGA gain of 4. WTF? Does Analog expect all it's customers to have to characterise the devices themselves over time/temperature/batchs etc. A major fail in the datasheet is that the integral linearity isn't properly specified - it only provides a typical +/-15ppm figure and only for a PGA gain of 4. It has much less memory (32K Flash, 4K RAM v 128K/16K) and the ADCs are noisier (20.2 bits 50Hz output data rate v 22.4). I had a quick look at the ADC7061 ADuC7061- $4.3 1K from cheapest distributer compared to $1.57 for the R5F523T5ADFL#30 Wrong part - the R5F523E5ADFL#30 is the cheapest part with the 24b ADCs costing $7.33. So has anyone developed with RX micros and used e2studio? What was the experience like compared to say using STM's tools and development boards? Flakey/unreliable emulators in particular are not uncommon. But just because they are available doesn't mean they are any good. They also have a range of stand-alone debuggers ranging from an £53 E2 emuator to the £897 E20 emulator with instruction trace. But perhaps I've got this wrong as I see they do a low cost (£23) target board with debugger and emulation support: There is an Eclipse based IDE, e2studio which supports the GNU compiler which is promising and there are support forums. I was under the impression that Renesas were only interested in large OEMs, especially the automotive sector rather than the hobby/SME arena and thus development tools were expensive and support limited or non-existent.

In another thread PCB.Wiz drew my attention to the RX23E 32 bit micros with 24bit ADCs that look interesting.
