Product details
Overview
R5F102AADSP#V0 from Renesas is a 30-pin LSSOP packaged RL78/G12 16-bit MCU with 16 KB code flash, 2 KB data flash, and 2 KB RAM, operating at 1.8–5.5 V and delivering 31 DMIPS at 24 MHz. It integrates an 8/10-bit 8-channel ADC, dual UART (UART0 + UART1), CSI00/CSI11, IIC00/IIC11, TAU timer with 8 channels, DMA controller (2 ch), CRC engine, and operates across –40°C to +85°C for industrial applications.
For engineers reviewing the R5F102AADSP#V0 datasheet, R5F102AADSP#V0 pinout, R5F102AADSP#V0 application, or R5F102AADSP#V0 equivalent, key selection criteria include its industrial-grade temperature range (–40°C to +85°C), on-chip 2 KB data flash with 1M rewrite cycles, dual UART support, integrated CRC and RAM/SFR guard safety features, and low-power HALT/STOP/SNOOZE modes enabling battery-powered sensor nodes and smart actuators.
Technical Context
The R5F102AADSP#V0 implements the RL78 CPU core with CISC architecture, 3-stage pipeline, and 1 MB address space. It supports high-speed on-chip oscillator (1–24 MHz, ±1.0% accuracy at –20°C to +85°C) and external crystal (1–20 MHz), with dedicated low-speed 15 kHz on-chip oscillator for watchdog operation.
Its peripheral set includes TAU0 with 8 timer channels (supporting PWM, input capture, output compare), SAU0 with 4 channels for UART/CSI/IIC, and dual serial interfaces (UART0 + UART1) plus two independent I²C modules (IIC00 and IIC11), all configurable via Peripheral I/O Redirection Register (PIOR).

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F102AADSP#V0 | Same package, same pinout, identical peripherals - only differs in ROM number coding (AA vs AADSP); confirmed as identical functional part per Renesas ordering matrix | No functional difference - used interchangeably in production BOMs | Select R5F102AADSP#V0 only if legacy design documentation references that variant; otherwise prefer R5F102AADSP#V0 for traceability |
| R5F103AADSP#V0 | Omits 2 KB data flash, DMA, CRC, RAM/SFR guard; UART/I²C count reduced to single instance; oscillator accuracy ±5.0% (vs ±1.0%) | Suitable for cost-sensitive, non-safety-critical consumer applications where background data logging or functional safety is not required | Choose only when data flash, CRC, or industrial temp stability are unnecessary - avoids over-specifying for simple control tasks |
Compared with R5F102AADSP#V0, R5F102AADSP#V0 is functionally identical and interchangeable, whereas R5F103AADSP#V0 removes critical industrial features (data flash, DMA, CRC, guard logic) and relaxes oscillator tolerance - making it unsuitable for applications requiring field firmware updates or functional safety compliance.

FAQ
What is the maximum operating frequency and corresponding DMIPS rating for R5F102AADSP#V0?
The R5F102AADSP#V0 achieves a maximum operating frequency of 24 MHz using its high-speed on-chip oscillator, delivering 31 DMIPS performance. This is measured under HS (high-speed main) mode with VDD = 2.7–5.5 V. The minimum instruction execution time is 0.04167 µs at 24 MHz, confirming deterministic real-time behavior suitable for motor control loops and sensor fusion algorithms.
Does R5F102AADSP#V0 support background data flash programming while executing application code?
Yes, R5F102AADSP#V0 supports Background Operation (BGO) for its 2 KB data flash memory. This allows the CPU to execute instructions from code flash while simultaneously erasing or writing data flash sectors - essential for logging operational data or storing calibration parameters without interrupting real-time tasks.
What safety features are integrated into R5F102AADSP#V0 beyond basic watchdog and voltage detection?
R5F102AADSP#V0 includes CRC calculation hardware, RAM guard, and SFR guard - features absent in the R5F103 series. These detect unintended memory writes, prevent accidental register corruption, and validate firmware integrity, making R5F102AADSP#V0 suitable for IEC 61508 SIL-2–capable subsystems in industrial control applications.
Can R5F102AADSP#V0 operate reliably at 1.8 V supply voltage with full peripheral functionality?
Yes, R5F102AADSP#V0 is fully specified for operation at 1.8 V across its entire industrial temperature range (–40°C to +85°C). All peripherals - including 8/10-bit ADC, UART, I²C, and TAU timers - remain functional at minimum VDD, enabling direct interfacing with 1.8 V logic and ultra-low-power battery systems.
How many UART and I²C interfaces does R5F102AADSP#V0 provide, and are they independently configurable?
R5F102AADSP#V0 provides two UART channels (UART0 and UART1) and two I²C channels (IIC00 and IIC11), each with dedicated SDA/SCL pins and independent clock sources. They are fully configurable via the Peripheral I/O Redirection Register (PIOR), allowing flexible pin assignment without hardware redesign - e.g., routing UART1 to P13/P14 while retaining IIC00 on P60/P61.
