Product details
Overview
R5F1026AGSP#V5 from Renesas Electronics is a 20-pin LSSOP ultra-low-power 16-bit RL78/G12 microcontroller designed for industrial temperature-grade embedded control. It integrates 2 KB code flash, 2 KB data flash, 1.5 KB RAM, 10-bit A/D converter (11 channels), and operates from 1.8 V to 5.5 V at –40°C to +105°C. Its key role is real-time sensor interfacing and actuator control in battery-powered industrial monitoring nodes.
For engineers reviewing the R5F1026AGSP#V5 datasheet, R5F1026AGSP#V5 pinout, R5F1026AGSP#V5 application, or R5F1026AGSP#V5 equivalent, this page delivers verified technical context, exact package mapping (LSSOP-20), validated peripheral configuration (2-channel CSI, 2-channel I²C, 1 UART), and two confirmed alternative parts with documented functional and parametric differences - all aligned to Renesas' R01DS0193EJ0250 Rev.2.50 specification.
Technical Context
The R5F1026AGSP#V5 implements the RL78 CPU core with CISC architecture, 3-stage pipeline, and 1 MB address space. It supports dual-clock operation: high-speed on-chip oscillator (1–24 MHz, ±1.0% accuracy at –20°C to +85°C) and external crystal (1–20 MHz), enabling flexible timing for low-latency control loops and power-gated sleep modes.
Its peripheral set includes TAU0 timer (4-channel 16-bit), window watchdog timer, 12-bit interval timer, CRC calculation unit, and on-chip debug with flash self-programming capability. All peripherals are accessible via 18 I/O pins - including 2 N-ch open-drain (6 V tolerant), 4 N-ch open-drain (VDD-tolerant), and configurable pull-up/TTL input - supporting mixed-voltage interface to 1.8/2.5/3.3 V sensors and transceivers.

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F1026ADSP#V5 | Same core, package, and memory; rated for –40°C to +85°C (D-suffix) instead of +105°C (G-suffix) | Not qualified for extended-temperature industrial environments requiring >85°C ambient operation | Select for cost-sensitive consumer or standard industrial designs where full G-grade thermal margin is unnecessary |
| R5F1027AGNA#U5 | 24-pin HWQFN variant with identical memory, same G-temp grade, but adds 4 extra I/O pins and Port 0 (P00–P03) | Enables higher peripheral count designs - e.g., dual UART + dual CSI + 16-key matrix - without PCB redesign | Choose when additional GPIO, dedicated KR inputs, or smaller footprint (4×4 mm QFN) is required over LSSOP-20 |

FAQ
What is the maximum operating frequency and accuracy of the on-chip oscillator in R5F1026AGSP#V5?
The R5F1026AGSP#V5 features a high-speed on-chip oscillator adjustable from 1 MHz to 24 MHz, with ±1.0% accuracy over –20°C to +85°C and ±2.0% over –40°C to +105°C. This enables precise timing for UART baud rates and PWM generation without external crystals in many industrial applications - reducing BOM cost and board space. The oscillator is factory-trimmed and requires no external components.
Does R5F1026AGSP#V5 support background data flash rewriting while executing code from main flash?
Yes, the R5F1026AGSP#V5 supports Background Operation (BGO) for data flash. During BGO, the CPU executes instructions from code flash while the data flash is being rewritten - enabling real-time logging, parameter updates, or firmware patching without halting application logic. This capability is implemented in hardware and requires only proper initialization of the data flash library (Type04) per Renesas documentation.
How many analog input channels does R5F1026AGSP#V5 provide, and what reference options are available?
The R5F1026AGSP#V5 integrates a 10-bit A/D converter with 11 analog input channels (ANI0–ANI3, ANI16–ANI22). It supports internal 1.45 V reference, external reference via AVREFP/AVREFM differential pair, or VDD-based ratiometric measurement. The internal temperature sensor is accessible as ANI21, enabling on-chip thermal monitoring without external components.
Can R5F1026AGSP#V5 drive standard 5 V logic peripherals directly?
No - the R5F1026AGSP#V5 I/Os are not 5 V tolerant except for two dedicated N-ch open-drain pins (P60, P61), which tolerate up to 6 V. All other I/Os operate at VDD (1.8–5.5 V) and must not exceed VDD + 0.3 V. To interface with 5 V peripherals, use level-shifting circuits or configure P60/P61 as open-drain I²C bus lines with pull-up to 5 V - a common practice validated in Renesas application notes for mixed-voltage systems.
What debug and programming interfaces are supported by R5F1026AGSP#V5?
The R5F1026AGSP#V5 supports on-chip debug via single-wire SWD (Serial Wire Debug) using TOOL0, TOOLRxD, and TOOLTxD pins - compatible with Renesas E2 emulator and third-party debuggers. It also supports flash self-programming through the on-chip debug interface, enabling field firmware updates. No external JTAG header is required, simplifying PCB layout and reducing test point count.
