The ability to use functions such as the data transfer controller (DTC), event link controller (ELC), and data operation circuit (DOC) to perform data processing and transfer, and implement long-interval timers, all without the need for CPU intervention, helps to further reduce power consumption during intermittent system operation by approximately 30 percent. In the low-power operation mode, the RL78/I1D Group has an operating current level much lower than that of competing products, and it wakes up from the stop-mode state very quickly. The MCU alone can make a substantial contribution to the overall power efficiency of the system.

To help reduce system cost and allow for greater compactness, the new RL78/I1D Group integrates general-purpose differential input operational amplifiers, a 12-bit A/D converter, and a comparator. This brings together on a single chip all the analog peripheral functions required to interface with sensors.

Features:

－ Innovative snooze mode functions enabling data processing and transfer without CPU intervention

－ Dynamic switching of the operation mode to match the system status

－ On-chip analog peripheral functions necessary for detecting minute sensor signals
