To meet the needs of a wide range of applications in this area, Renesas provides different levels of Program and Data Flash memory. At the low-end of the scale is the R8C2J with as little as 2KB of program memory and no Data Flash option. At the other extreme, in 24-pin packages, the R8C/3Gx provides 4K of Data Flash in addition to its 32KB of Program Flash. Some devices such as 2J and 2H offer analog comparators as their only analog interface. For those applications requiring analog to digital conversion, the R8C/28, 29 is an ideal candidate. If there is a need for a low-pin count solution with a D/A converter, users can select R8C/3xG. The number of input to output options also varies even within the same package. For example, the 2J provides up to 12 I/O, while the R8C/28-29 has 16, and both are offered in a 20-pin package. Finally, the last difference to point out is related to standby power consumption. In general, R8C/2x groups can achieve sub 1µA current consumption and still be able to retain all contents in RAM. The 0.8µA shown here is the typical value at 5V operation. This low-power consumption makes these devices ideal for battery operated applications.
