It integrates 16 KB code flash, 2 KB data flash, 1.5 KB RAM, a 24 MHz high-accuracy on-chip oscillator (±1.0% over –40°C to +85°C), and operates from 1.8 V to 5.5 V. It delivers 31 DMIPS at 24 MHz and supports HALT/STOP/SNOOZE low-power modes-ideal for battery-powered sensor nodes and smart actuators.
For engineers reviewing the R5F1026AGSM#15 datasheet, R5F1026AGSM#15 pinout, R5F1026AGSM#15 application, or R5F1026AGSM#15 equivalent, this page provides verified technical context, validated pin functions, real-world use scenarios, and two confirmed alternative parts with documented functional and application-level differences.
Technical Context
The R5F1026AGSM#15 implements the RL78 CPU core with a 3-stage pipeline CISC architecture, 1 MB address space, and four banks of 8-bit general-purpose registers. Its power management includes on-chip POR, 12-level LVD, and dedicated low-speed (15 kHz) watchdog timer operation.
Peripheral integration includes dual CSI (Simplified SPI) channels, dual Simplified I²C channels, one UART channel, 11-channel 10-bit A/D converter with internal 1.45 V reference and temperature sensor, four 16-bit TAU timer channels, DMA controller (2 channels), CRC engine, and programmable clock/buzzer output (PCLBUZ0). All peripherals are accessible via 18 I/O pins-including two 6-V-tolerant N-ch open-drain outputs.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F1026AASM#15 | Same package and pinout; consumer-grade (–40°C to +85°C) instead of industrial G-grade; identical flash/RAM/peripherals | Not rated for +105°C operation; unsuitable for enclosed industrial enclosures or under-hood automotive | Select when ambient temperature remains ≤+85°C and cost sensitivity outweighs extended thermal qualification |
| R5F1036AGSM#15 | Removes 2 KB data flash and DMA; reduces oscillator accuracy to ±5.0%; retains same code flash, RAM, and I/O count | Lacks background data logging capability and high-throughput peripheral offload; lower timing precision limits closed-loop control bandwidth | Choose when firmware updates are infrequent, real-time throughput demands are modest, and BOM cost reduction is critical |
Compared with R5F1026AASM#15, the R5F1026AGSM#15 adds guaranteed +105°C operation for harsh environments; compared with R5F1036AGSM#15, it retains data flash and DMA for robust field-upgradability and peripheral bandwidth-making it optimal for thermally demanding, data-intensive edge nodes.

FAQ
What is the maximum operating frequency and corresponding performance of the R5F1026AGSM#15?
The R5F1026AGSM#15 supports a maximum system clock of 24 MHz using its high-accuracy on-chip oscillator, delivering 31 DMIPS of processing performance. At this frequency, the minimum instruction execution time is 0.04167 µs. The device maintains full functionality-including A/D conversion, serial interfaces, and timers-across its entire 1.8 V to 5.5 V supply range and –40°C to +105°C operating temperature.
Does the R5F1026AGSM#15 include data flash memory, and what are its key characteristics?
Yes, the R5F1026AGSM#15 integrates 2 KB of data flash memory with background operation (BGO) capability, allowing program execution from code flash while simultaneously rewriting data flash. It supports 1,000,000 write/erase cycles (typical) and operates across the full 1.8 V to 5.5 V supply range-enabling reliable parameter storage, calibration data retention, and firmware update staging without external EEPROM.
How many analog input channels does the R5F1026AGSM#15 support, and what resolution and reference options are available?
The R5F1026AGSM#15 features an 11-channel, 10-bit A/D converter with selectable 8-bit or 10-bit resolution. It supports internal 1.45 V reference voltage and includes an integrated temperature sensor. Analog inputs accept voltages from –0.3 V to VDD + 0.3 V (or AVREF(+) + 0.3 V), enabling direct connection to common sensors without signal conditioning in most industrial sensing applications.
What serial communication interfaces are available on the R5F1026AGSM#15, and how are they configured?
The R5F1026AGSM#15 provides one UART channel, two Simplified SPI (CSI) channels, and two Simplified I²C channels-all implemented in the SAU0 peripheral. These interfaces share pins via peripheral I/O redirection (PIOR), allowing flexible assignment of SCK/SI/SO or SCL/SDA functions to designated port pins without hardware changes. No external transceivers are needed for standard 3.3 V or 5 V bus operation.
What low-power modes does the R5F1026AGSM#15 support, and what are their typical current consumptions?
The R5F1026AGSM#15 supports HALT, STOP, and SNOOZE modes. In active mode, it consumes 63 µA/MHz at 24 MHz. HALT mode stops the CPU clock while preserving RAM and register contents; STOP mode halts all clocks except the low-speed watchdog; SNOOZE mode allows selected peripherals (e.g., A/D, UART) to operate autonomously while the CPU sleeps. STOP current is below 1 µA, enabling multi-year battery life in intermittent-sensing applications.
