Product details
Overview
R5F11EF8AFP#30 from Renesas is an 8 KB flash, 1.5 KB RAM RL78/G1G 16-bit microcontroller in 44-pin LQFP (10 × 10 mm, 0.8 mm pitch), operating at 2.7–5.5 V with -40 to +85°C ambient range. It integrates a 24 MHz high-accuracy (±2%) on-chip oscillator, 12-channel 10-bit ADC, two comparators with programmable DAC reference, and seven 16-bit timers - deployed in battery-powered sensor nodes and industrial control panels requiring ultra-low-power STOP/HALT modes.
For engineers reviewing the R5F11EF8AFP#30 datasheet, R5F11EF8AFP#30 pinout, R5F11EF8AFP#30 application, or R5F11EF8AFP#30 equivalent, this page delivers verified package mapping, validated peripheral I/O assignments, confirmed timing and analog performance specs, and real-world substitution guidance for production BOMs targeting consumer and industrial embedded systems.
Technical Context
The R5F11EF8AFP#30 implements the RL78 CPU core with 3-stage pipeline, supporting 16-bit multiply/divide/accumulate instructions and 1 MB address space. Its clock system combines selectable high-speed on-chip oscillator (1–24 MHz) with external crystal (1–20 MHz) and low-speed 15 kHz internal oscillator for watchdog and interval timing.
Peripheral integration includes UART0/UART1, simplified SPI (CSI), simplified I²C, Event Link Controller (19 event inputs), programmable gain amplifier (PGAI), and dual comparator channels with 8-bit DAC reference generation - all mapped to 40 total I/O pins including 12 analog inputs and key-return support (KR0–KR3).
