Product details
Overview
R5F11768GSM#30 from Renesas Electronics is an RL78/I1D 8-bit microcontroller designed for ultra-low-power industrial applications. It features 8 KB code flash, 2 KB data flash, 0.7 KB RAM, 20-pin TSSOP package, and operates from 1.6 V to 3.6 V across –40°C to +105°C. Its integrated 12-bit A/D converter (6 channels), two comparators, four operational amplifiers, and real-time clock support sensor interface and battery-powered control systems.
For engineers reviewing the R5F11768GSM#30 datasheet, R5F11768GSM#30 pinout, R5F11768GSM#30 application, or R5F11768GSM#30 equivalent, key selection criteria include its 58.3 μA/MHz active current, 0.64 μA STOP mode, 20-pin TSSOP footprint, 24 MHz high-accuracy on-chip oscillator (±1.0%), and dual-clock domain (main + subsystem) for flexible power/performance trade-offs in embedded sensing and timing-critical control.
Technical Context
The R5F11768GSM#30 implements the RL78 CPU core with CISC architecture, 3-stage pipeline, and configurable instruction execution time (0.04167 μs at 24 MHz to 66.6 μs at 15 kHz). It integrates a dedicated regulator with REGC pin filtering, separate analog (AVDD/AVSS) and digital (VDD/VSS) supplies, and hardware peripherals including DTC (16 sources), ELC (15 event inputs), and programmable clock/buzzer output.
Its clock system supports concurrent operation of high-speed on-chip oscillator (24 MHz), middle-speed (4 MHz), low-speed (15 kHz), and external crystal oscillators (X1 up to 20 MHz, XT1 at 32.768 kHz), enabling precise RTC2 calendar functions, low-power wake-up via INTP0–INTP2, and seamless transition between HALT/STOP/SNOOZE modes without firmware overhead.
