Low Power Consumption

As mentioned earlier, the RX140 consumes less power than previous products. Here is a side-by-side comparison of the RX140 against the RX130. At a clock rate of 32 MHz, the RX140 reduces the active current by over 30% from the RX130. Of course, if the RX140 is run at its full clock rate of 48 MHz, the current will be higher, but this will allow customers to trade off performance and current draw by varying the clock rate to achieve their active power consumption targets. For standby current, the RX140 drops to 0.21 µA from the RX130 value of 0.37 µA, over 40% reduction. So, the RX140 will be even more appealing to battery powered and battery backup applications. In addition, the RX140 will add a Snooze mode, enabling peripheral operation without waking the CPU, giving the customer more options to reduce their overall system power consumption.
