Description:The RX113 Group microcontrollers have built-in communications functions such as USB and IrDA, a capacitive touch sensor (CTSU), a segment LCD, and a serial sound interface (SSI). They offer a single-chip solution for industrial and measuring devices that have low current supply capabilities, or for user interfaces for system control in home appliances, healthcare devices, and so on.
Renesas recommends using a POR circuit with a 1 kΩ resistor, a 10 μF capacitor, and a diode (e.g., 1N4148) to ensure a clean power-on reset. This circuit helps to prevent latch-up and ensures that the device resets properly.
The R5F51138ADLJ#2A has a flexible clock system that can be configured using the Clock Generator (CG) module. You can select the clock source (e.g., internal oscillator, external clock, or PLL), set the clock frequency, and configure the clock dividers using the CG registers. Refer to the datasheet and the Renesas clock configuration tool for more information.
The R5F51138ADLJ#2A has an operating temperature range of -40°C to +125°C. However, the device can be operated at a reduced frequency and voltage at higher temperatures. Refer to the datasheet for more information on temperature derating.
The R5F51138ADLJ#2A has a built-in WDT that can be enabled and configured using the WDT registers. You can set the WDT timeout period, enable or disable the WDT, and configure the WDT reset behavior using the WDT control registers. Refer to the datasheet for more information on WDT configuration.
The maximum current consumption of the R5F51138ADLJ#2A depends on the operating frequency, voltage, and peripheral usage. According to the datasheet, the typical current consumption is around 10 mA at 5 V and 20 MHz. However, this value can increase depending on the specific application and usage. Refer to the datasheet for more information on power consumption.
