Product details
Overview
R5F1026AGSP#35 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 16 KB code flash, 2 KB data flash, 1.5 KB RAM, operates from 1.8–5.5 V, delivers 31 DMIPS at 24 MHz, and supports -40°C to +105°C ambient operation (G-grade) - ideal for motor control in HVAC actuators and smart sensor nodes requiring long battery life and robust field reliability.
For engineers reviewing the R5F1026AGSP#35 datasheet, R5F1026AGSP#35 pinout, R5F1026AGSP#35 application, or R5F1026AGSP#35 equivalent, this page provides verified technical context, validated pin functions, real-world use scenarios, and confirmed alternative options - all aligned with Renesas' R01DS0193EJ0250 Rev.2.50 specification and RL78/G12 product family documentation.
Technical Context
The R5F1026AGSP#35 implements the RL78 CPU core with CISC architecture, 3-stage pipeline, and 1 MB address space. It features dual on-chip oscillators: high-speed (1–24 MHz, ±1.0% accuracy at -20 to +85°C) and low-speed (15 kHz), enabling dynamic clock switching between HALT, STOP, and SNOOZE modes for sub-63 μA/MHz active power consumption.
Its peripheral set includes a 10-bit 11-channel A/D converter with internal 1.45 V reference and temperature sensor, four 16-bit TAU timer channels with PWM capability, two CSI/SPI channels, two simplified I²C interfaces, one UART, DMA controller (2 channels), CRC engine, RAM guard, and SFR guard - all confirmed for the R5F102 series and explicitly present in 20-pin G-grade variants per datasheet Figures 1-1, 1.6.1, and Table 1-1.
