Product details

The R5F51101AGFM#30 is a Renesas RX110 32-bit MCU clocked at 32 MHz, built around the RX core. It packs 32 KB of Flash and 10 KB of RAM, enough for a single motor-control loop, a sensor-fusion algorithm, or a Modbus RTU gateway node. The 50 GPIOs give headroom for parallel sensor inputs and a local display interface. The 14-channel 12-bit ADC captures analog feedback from current shunts or thermistors without an external converter. Connectivity covers I²C, SCI (UART), and SPI, so it ties into common sensor modules and serial displays.

Industrial temperature range — where it lives on the board

The POR and LVD blocks handle power-up sequencing and brownout recovery.

Store the reels in a dry cabinet — the 64-LQFP is moisture-sensitive, and a bake cycle before reflow adds cost if the seal is broken.

Frequently asked questions

Where can I buy R5F51101AGFM#30?

This part is sourced to order through independent distribution. Submit an RFQ for current pricing and lead time on your target quantity.

What is the closest functional equivalent to R5F51101AGFM#30?

The R5F51103AGFM#30 is a pin-compatible sibling in the same RX110 series, also 32 MHz with 50 I/O and the same peripheral set. The difference is program memory: the R5F51103AGFM#30 carries 48 KB Flash versus 32 KB on this part. If your firmware fits in 32 KB, the R5F51101AGFM#30 is the cost-optimized choice.
