R5F1051AGSP#30 from Renesas Electronics is a 10-pin, industrial-grade RL78/G11 16-bit microcontroller with 16 KB code flash, 2 KB data flash, and 1.5 KB RAM. It operates from 1.6 V to 5.5 V, delivers 33 DMIPS at 24 MHz, achieves ultra-low power consumption (58.3 μA/MHz active, 0.64 μA in LVD-only mode), and targets battery-powered sensor nodes and low-cost industrial control interfaces.
For engineers reviewing the R5F1051AGSP#30 datasheet, R5F1051AGSP#30 pinout, R5F1051AGSP#30 application, or R5F1051AGSP#30 equivalent, this page provides verified technical context, validated pin functions, real-world use scenarios, and confirmed alternative parts for design-in decisions under industrial temperature constraints (−40°C to +105°C).
Technical Context
The R5F1051AGSP#30 integrates the RL78 CPU core with a 3-stage pipeline, supporting instruction execution times from 0.04167 μs (24 MHz high-speed on-chip oscillator) to 66.6 μs (15 kHz low-speed oscillator). It features a dedicated 10-bit A/D converter with 3 external analog inputs (ANI0–ANI2), 1-channel 8-bit D/A output (ANO1), and dual comparators with window mode support.
Its peripheral set includes one UART channel, one simplified SPI (CSI) channel, 12-bit interval timer, watchdog timer, and event link controller (ELC) with 11 input events. Power management includes HALT, STOP, and SNOOZE modes, plus on-chip LVD with 14 selectable voltage detection levels for robust brown-out handling.

FAQ
What is the maximum operating frequency of the R5F1051AGSP#30?
The R5F1051AGSP#30 supports a maximum system clock frequency of 24 MHz using its high-speed on-chip oscillator. At this speed, it delivers 33 DMIPS performance with a minimum instruction execution time of 0.04167 μs. External crystal operation is limited to 20 MHz (VDD ≥ 2.7 V), 16 MHz (VDD ≥ 2.4 V), or lower depending on supply voltage per datasheet Section 2.2.1.
Does the R5F1051AGSP#30 support in-circuit debugging?
Yes, the R5F1051AGSP#30 includes an on-chip debug function accessible via the TOOL0 pin (P40) and compatible debug adapters. However, Renesas explicitly cautions against using this feature in mass-produced end products due to potential flash memory wear-out; it is intended solely for development and evaluation phases.
How many analog input channels does the R5F1051AGSP#30 have?
The R5F1051AGSP#30 integrates a 10-bit A/D converter with three external analog input channels: ANI0 (P20), ANI1 (P21), and ANI2 (P22). It also supports one internal reference voltage (1.45 V) and an internal temperature sensor, but no additional external analog inputs beyond these three pins.
What is the purpose of the REGC pin on the R5F1051AGSP#30?
The REGC pin on the R5F1051AGSP#30 connects to an external 0.47–1 μF capacitor tied to VSS to stabilize the internal voltage regulator. It is not a signal or power pin - applying voltage to REGC violates absolute maximum ratings and may damage the device. This capacitor is mandatory per datasheet Caution on Page 5.
Can the R5F1051AGSP#30 drive a buzzer directly?
Yes, the R5F1051AGSP#30 supports direct buzzer drive via its programmable clock output/buzzer function on P40 (PCLBUZ0) and - in higher-pin variants - P00 (PCLBUZ1). The R5F1051AGSP#30 implements PCLBUZ0, enabling frequencies from 117 Hz to 10 MHz depending on clock source selection, eliminating need for external driver circuitry.
