The PTM will now spend a few minutes introducing the product variants in more detail. The first set of devices shown here is the R8C/2x Series grouped by pin count – the second number inside the boxes represent the models with data flash. Starting from the left, the R8C/24, 25 groups were the first devices introduced in the 2x Series. The R8C/24 and 25 are 100% compatible, with the exception of the data flash only available in the latter group. Next is the R8C/22 and 23 variations  These groups come in 48-pin packages and offer flash sizes as large as 128KB. Originally designed for automotive applications, these devices include CAN interfaces and are also available in industrial grade. Right below it are the 20 and 21 groups. These are 100% compatible with the 22 and 23 groups, but do not include CAN. Down and to the left on the chart are the 32- and 20-pin options; 26, 27 and 28 ,29 respectively. Besides lower flash sizes these devices offered less functionality than the 24 and 25 making them a good fit for lower-cost designs. The next wave of products started with 80- and 64-pin packages. At the very top, R8C/2C and 2D can be considered the superset devices under the R8C/2x series. These products add additional functions such as D/A, 16-bit timers, and up to 20 channels of A/D. Both groups are ideal for main system control which requires many I/Os and large flash. The two sets of groups with a green outline are part of the R8C application-specific line-up. Based on the experience and success of the R8C/24,25 in the motor control space, Renesas decided to develop the R8C/2K,2L which are fully optimized for this application. The parts include an additional 16-bit timer used for the motor's feedback sensors and come in a 32-pin package which is better suited for single board motor control systems. Right below those parts are the R8C/2E,2F. These 32-pin devices incorporate two channels of D/A converters, which can be connected internally to two separate analog comparators; a feature useful for lighting control applications. To address lower-end system requirements, Renesas developed the R8C/2G, 2H and 2J groups. These devices outlined in yellow have been optimized for cost – they only offer non-data flash options, include simple comparator circuits as the only analog interface and incorporate a lower 8MHz internal oscillator. These devices are great options for very cost sensitive applications while offering compatibility with the rest of the series. Next is the R8C/3x Series. While these devices maintain backward compatibility with R8C/2x, they incorporate major enhancements making them a great complement to the R8C family. Key features of the 3x series include: expansion of operating voltage range from 1.8V to 5.5V, added performance through the Data Transfer Controller, co-processing capabilities with its Data Flash Background Operation, larger RAM to ROM ratio, and CAN in 64- and 80-pin packages.
