• Includes hardware peripherals such as DMA, LVD, POR, PWM, and WDT.
• Features an analog-to-digital converter with configurable 8-bit or 10-bit resolution.

Microcontrollers Applications

• General-purpose embedded control systems
• Industrial automation controllers
• Consumer appliance logic boards

Microcontrollers Procurement Notes

Verify the specific suffix #W0 against official Renesas documentation to confirm packaging configuration, as suffixes often denote tape-and-reel formats distinct from tray packaging. Confirm current lifecycle status directly with the manufacturer, as distributor listings may indicate limited availability or end-of-life conditions that require formal obsolescence notices.

Microcontrollers Selection Notes

Select this model when a 16-bit RL78 core is required with 48KB of flash and a 32-pin QFN footprint. Ensure the design accommodates the 1.6V to 5.5V supply range and utilizes the internal oscillator if external crystal resources are constrained. Verify pin compatibility with existing layouts due to the specific HWQFN-32 mechanical dimensions.

Microcontrollers Part Context

This component belongs to the RL78/G13 family, which targets low-power, high-performance applications. The R5F101B variant specifically offers a balance of memory capacity and I/O density suitable for cost-sensitive embedded designs requiring robust peripheral integration and wide voltage operation.
