Scalability provides design flexibility, making it easy to choose an MCU with the right combination of I/O memory size and functionality at the right price. This is in fact the strongest benefit provided by the R8C Family as a whole. The R8C line-up as shown here consists of multiple series. For general purpose and application-specific requirements, R8C offers the 1x, 2x and 3x series. Each series offers different levels of integration and performance. The map on the right hand side shows that these devices cover a very wide range of Flash memory sizes and pin counts. For those applications requiring a built-in LCD controller, designers can take advantage of the R8C/Lx series. The initial line-up of the R8C/Lx consists of high-end products ranging from 48KB to 128KB of Flash memory in packages as large as 100-pin. With these four series, the R8C Family offers over 1000 unique part numbers all having the compatible CPU and peripheral set.
