Overview
R5F102AAGSP#30 from Renesas Electronics is a 30-pin LSSOP ultra-low-power 16-bit RL78/G12 microcontroller designed for industrial embedded control in temperature-critical environments. It integrates 16 KB code flash, 2 KB data flash, 2 KB RAM, 8-channel 10-bit ADC, and dual UART/CSI/I²C serial interfaces - all operating at 1.8–5.5 V with true low-power consumption (63 μA/MHz) and -40°C to +105°C extended temperature range (G-grade).
For engineers reviewing the R5F102AAGSP#30 datasheet, R5F102AAGSP#30 pinout, R5F102AAGSP#30 application, or R5F102AAGSP#30 equivalent, this page delivers verified technical context, validated pin functions, real-world use-value per application, and two confirmed alternative parts with documented functional and application-level differences.
Technical Context
The R5F102AAGSP#30 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting minimum instruction execution time of 0.04167 µs at 24 MHz (high-speed on-chip oscillator), 1 MB address space, and four banks of 8-bit general-purpose registers. Its power management includes HALT, STOP, and SNOOZE modes plus on-chip POR and 12-level LVD.
It features dual DMA channels, CRC operation, RAM/SFR guard safety functions, and a voltage regulator (REGC pin) enabling stable internal supply. The peripheral set includes TAU timer with 8 channels (7 PWM-capable), window watchdog timer, 12-bit interval timer, and programmable clock/buzzer outputs (PCLBUZ0/PCLBUZ1), all configured via PIOR register for flexible I/O redirection.

Applications
| Industrial Motor Control | Smart HVAC Sensor Node |
|---|---|
Use Scenario: Closed-loop speed regulation of BLDC fans using hall-effect feedback and PWM-driven gate drivers.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F102AAASP#30 | G-grade (-40°C to +105°C) same package and memory, but A-grade (-40°C to +85°C) variant; identical peripherals and pinout | Not rated for extended industrial ambient; unsuitable where cabinet temperatures exceed +85°C | Select only if end-equipment operates strictly within consumer-grade thermal envelope |
| R5F103AAGSP#30 | No data flash (0 KB), no DMA, no CRC/RAM/SFR guard, reduced serial interface count (UART×1, CSI×1, I²C×0) | Lacks non-volatile parameter storage and safety features; insufficient for firmware-over-the-air or functional-safety designs | Choose when cost sensitivity outweighs data retention and safety requirements |
Compared with R5F102AAGSP#30, the R5F102AAASP#30 offers identical functionality at lower thermal rating, while R5F103AAGSP#30 sacrifices data flash, DMA, and safety peripherals - making the original part uniquely suited for robust, field-upgradable industrial edge nodes requiring long-term parameter persistence and runtime integrity checks.

The R5F102AAGSP#30 supports a maximum system clock of 24 MHz using its high-speed on-chip oscillator, achieving 31 DMIPS performance. When using an external crystal (X1/X2), the maximum frequency is 20 MHz under VDD ≥ 2.7 V, or 16 MHz at 2.4–2.7 V, ensuring timing compliance across voltage and temperature conditions.
Does the R5F102AAGSP#30 include hardware data flash with background operation?
Yes, the R5F102AAGSP#30 integrates 2 KB of data flash memory with background operation (BGO) capability, allowing CPU instruction execution from program memory while simultaneously rewriting data flash - essential for firmware parameter updates without interrupting real-time control loops.
What safety features are implemented in the R5F102AAGSP#30?
The R5F102AAGSP#30 includes CRC calculation hardware, RAM guard, and SFR guard - all confirmed in the RL78/G12 datasheet for R5F102 products. These features detect memory corruption and prevent unauthorized register access, supporting IEC 61508 SIL2-ready designs in industrial control systems.
Can the R5F102AAGSP#30 operate from a 1.8 V supply?
Yes, the R5F102AAGSP#30 is fully specified for 1.8 V to 5.5 V operation, including all peripherals and flash programming. At 1.8 V, it supports up to 8 MHz main system clock (LS mode) and retains full functionality of ADC, timers, and serial interfaces - enabling compatibility with low-voltage battery-powered equipment.
How many UART interfaces does the R5F102AAGSP#30 support?
The R5F102AAGSP#30 supports two independent UART interfaces: UART0 (on P11/P12) and UART2 (on P13/P14). Both channels operate concurrently, enabling simultaneous communication with host processors and external modems or wireless modules without software multiplexing.
