Product details
Overview
R5F103AADSP#V0 from Renesas Electronics is a 30-pin LSSOP packaged 16-bit RL78/G12 microcontroller for industrial embedded control, featuring 16 KB code flash, 2 KB RAM, 10-bit 8-channel ADC, 1.8–5.5 V operation, and ultra-low power consumption (63 μA/MHz). It integrates UART0, CSI00, IICA0, TAU0 with 8 timer channels, and operates across –40°C to +85°C.
For engineers reviewing the R5F103AADSP#V0 datasheet, R5F103AADSP#V0 pinout, R5F103AADSP#V0 application, or R5F103AADSP#V0 equivalent, key selection criteria include its 30-pin LSSOP package, absence of data flash memory, reduced serial interface count (no Simplified I²C or second UART), and industrial-grade temperature rating (D-suffix) - all critical for cost-optimized sensor node and motor control designs requiring long-term supply stability.
Technical Context
The R5F103AADSP#V0 implements the RL78 CPU core with 3-stage pipeline CISC architecture, 1 MB address space, and configurable instruction execution time (0.04167 µs at 24 MHz). Its clock system combines a high-speed on-chip oscillator (±5.0% accuracy over –40°C to +85°C) and external crystal support (1–20 MHz).
Peripheral integration includes one UART channel (UART0), one simplified SPI (CSI00), one I²C-compatible interface (IICA0), eight 16-bit timer channels in TAU0, and an 8-channel 10-bit A/D converter with internal reference (1.45 V) and temperature sensor - all mapped to dedicated pins without peripheral I/O redirection required for basic operation.
Key Specifications

Pinout & Package
Package: 30-pin plastic LSSOP (7.62 mm, 0.65-mm pitch), RoHS-compliant, surface-mountable with standard reflow profile.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| P20/ANI0/AVREFP | Analog input / positive reference voltage | Primary analog input channel and AVDD reference source for ADC - must be decoupled with 0.1 µF capacitor |
| P21/ANI1/AVREFM | Analog input / negative reference voltage | Differential analog input and AVSS reference - enables ratiometric measurement against AVREFP |
| P10/SCK00/SCL00 | Serial clock output/input | Master clock for CSI00 or IICA0 - shared pin requires software configuration for protocol selection |
| P11/SI00/RxD0/SDA00 | Serial data input / UART receive / I²C data | Multi-function input supporting SPI slave-in, UART RX, or I²C SDA - selected via peripheral I/O redirection register (PIOR) |
| P12/SO00/TxD0/TOOLTxD | Serial data output / UART transmit / debug TX | Configurable as SPI SO, UART TX, or on-chip debugger output - default UART use simplifies host interface design |
| P13/TxD2/SO20/(SDAA0) | Secondary UART TX / SPI SO / I²C data | Not available on R5F103 series - this pin functions only as TxD2 or SO20; SDAA0 is exclusive to R5F102 products |
| P14/RxD2/SI20/SDA20 | Secondary UART RX / SPI SI / I²C data | Not available on R5F103 series - pin reserved for future expansion or unused in current variant |
| RESET | Active-low reset input | Asynchronous reset trigger with internal pull-up - compatible with open-drain reset supervisors and manual push-button circuits |
| X1/X2 | Crystal oscillator inputs | Supports 1–20 MHz fundamental-mode crystals - enables precise timing for UART baud rate generation and real-time control loops |
| VDD/VSS | Power supply / ground | Dual power pins with separate analog/digital ground routing recommended - ensures ADC noise immunity below 1 LSB |

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F102AADSP#V0 | Includes 2 KB data flash, CRC engine, RAM guard, DMA, and ±1.0% oscillator accuracy - adds 2 KB nonvolatile data storage and enhanced safety features | Required for firmware-over-the-air (FOTA) update staging or cyclic redundancy-checked control loop validation | Select when data logging, secure boot, or functional safety compliance (IEC 61508 SIL2) is mandated |
| R5F103A9DSP#V0 | Same package and pinout, but with 12 KB code flash and identical peripheral set - reduces BOM cost where firmware size <12 KB suffices | Suitable for legacy product refreshes with unchanged PCB layout and reduced memory footprint | Choose for cost-sensitive volume production where full 16 KB flash is unused and qualification effort must be minimized |
Compared with R5F102AADSP#V0, the R5F103AADSP#V0 trades data flash and safety peripherals for lower unit cost and simpler qualification, while R5F103A9DSP#V0 offers identical functionality at reduced memory capacity - both maintain pin compatibility and industrial temperature rating for seamless drop-in replacement in existing LSSOP-30 designs.

FAQ
What is the maximum operating frequency of the R5F103AADSP#V0?
The R5F103AADSP#V0 supports a maximum system clock frequency of 24 MHz using its high-speed on-chip oscillator. When driven by an external crystal, the maximum main system clock is 20 MHz. Instruction execution time reaches 0.04167 µs at 24 MHz, delivering 31 DMIPS performance - sufficient for real-time motor control and sensor fusion tasks without external acceleration.
Does the R5F103AADSP#V0 include data flash memory?
No, the R5F103AADSP#V0 does not include data flash memory. Per Renesas documentation, data flash (2 KB) is present only in R5F102-series variants. The R5F103AADSP#V0 relies solely on its 16 KB code flash for program storage and uses RAM for runtime variables - making it ideal for applications where nonvolatile parameter storage is handled externally or omitted entirely.
What serial communication interfaces are available on the R5F103AADSP#V0?
The R5F103AADSP#V0 provides one UART channel (UART0), one simplified SPI interface (CSI00), and one I²C-compatible interface (IICA0). Unlike R5F102 variants, it lacks Simplified I²C (IIC00/IIC01) and second UART (UART1/UART2) channels - limiting it to single-bus sensor networks or point-to-point host communication, which simplifies PCB routing and firmware development for basic control applications.
What is the operating temperature range for the R5F103AADSP#V0?
The R5F103AADSP#V0 is rated for industrial operation from –40°C to +85°C, indicated by the 'D' suffix in its part number. This range exceeds consumer-grade (–40°C to +85°C, 'A') and matches requirements for factory automation, building controls, and outdoor equipment - ensuring reliable startup and sustained operation under thermal stress without derating.
How many analog input channels does the R5F103AADSP#V0 support?
The R5F103AADSP#V0 supports 8 analog input channels (ANI0–ANI3, ANI16–ANI19) with 10-bit resolution and an internal 1.45 V reference voltage. It also integrates a calibrated temperature sensor usable as a system health monitor. This count is reduced from the 11-channel capability of 20-/24-pin R5F102 variants - aligning with the 30-pin package's focus on expanded digital I/O and timer resources rather than maximum analog density.
