Product details
Overview
R5F1026AGSP#X5 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 across –40°C to +105°C ambient. It delivers 31 DMIPS at 24 MHz and supports HALT/STOP/SNOOZE low-power modes - ideal for battery-powered sensor nodes and industrial HMI front-ends.
For engineers reviewing the R5F1026AGSP#X5 datasheet, R5F1026AGSP#X5 pinout, R5F1026AGSP#X5 application, or R5F1026AGSP#X5 equivalent, key selection criteria include its G-grade industrial temperature rating, on-chip 2 KB data flash with background operation (BGO), dual CSI/I²C serial interfaces, 2-channel DMA, and CRC hardware acceleration - all in a compact 4.4 × 6.5 mm LSSOP-20 package.
Technical Context
The R5F1026AGSP#X5 implements the RL78 CPU core with 3-stage pipeline CISC architecture, 1 MB address space, and configurable instruction timing (0.04167 µs min @ 24 MHz). Its power management includes on-chip POR, 12-level LVD, and dedicated low-speed oscillator for watchdog operation.
Peripheral integration centers on TAU0 4-channel 16-bit timer, SAU0 with 2 CSI channels and 2 I²C channels, UART0, 12-bit interval timer, and programmable clock/buzzer output. All serial interfaces support peripheral I/O redirection via PIOR register, enabling flexible pin assignment without PCB changes.

FAQ
What is the maximum operating frequency and corresponding DMIPS rating of the R5F1026AGSP#X5?
The R5F1026AGSP#X5 achieves a maximum operating frequency of 24 MHz using its high-speed on-chip oscillator, delivering 31 DMIPS of processing performance. This is measured under HS mode with VDD = 2.7–5.5 V and reflects the RL78 CPU core's 3-stage pipeline efficiency. The minimum instruction execution time is 0.04167 µs at this speed, enabling deterministic real-time response in control loops.
Does the R5F1026AGSP#X5 support background operation during data flash rewriting?
Yes, the R5F1026AGSP#X5 supports Background Operation (BGO) for its 2 KB data flash memory. This allows the CPU to execute instructions from program memory while simultaneously rewriting data flash - critical for seamless firmware updates and logging without system interruption. BGO is enabled via the Data Flash Control Register (DFLCTL) and requires proper interrupt masking during write sequences.
What are the key differences between the R5F1026AGSP#X5 and the R5F1036AGSP#X5?
The R5F1026AGSP#X5 includes 2 KB data flash, 2-channel DMA, CRC hardware, and RAM guard - features absent in the R5F1036AGSP#X5. The R5F1036AGSP#X5 omits data flash and safety peripherals but offers identical code flash (2 KB), I/O count, and core performance. Both share the same G-grade temperature rating and LSSOP-20 package, making them pin-compatible alternatives where data retention or safety certification is not required.
Which serial interfaces are available on the R5F1026AGSP#X5 and how are they configured?
The R5F1026AGSP#X5 provides one UART channel (UART0), two Simplified SPI (CSI) channels (CSI00, CSI01), and two I²C channels (IIC00, IICA0). These are implemented via the SAU0 peripheral and support flexible pin mapping through the Peripheral I/O Redirection Register (PIOR). Each interface can be assigned to multiple pins - for example, SDA00 appears on both P11 and P61 - allowing layout optimization without functional compromise.
What is the purpose of the REGC pin, and is it used on the R5F1026AGSP#X5?
The REGC pin is a regulator capacitance terminal used to stabilize the internal voltage regulator - but it is **not present** on the 20-pin R5F1026AGSP#X5. REGC appears only on 30-pin RL78/G12 variants (e.g., R5F102AAGSP#X0). The R5F1026AGSP#X5 uses a direct-regulated architecture and requires no external REGC capacitor, simplifying design and reducing BOM count for compact 20-pin implementations.
