Product details
Overview
R5F10ELEAFB#X0 from Renesas Electronics is a 64-pin LFQFP-packaged 16-bit RL78/G1A microcontroller with 64 KB flash, 4 KB data flash, 4 KB RAM, 28-channel 12-bit ADC, and ultra-low power operation down to 0.57 µA in RTC+LVD mode. It integrates UART, I²C, SPI, LIN, RTC, PWM, and on-chip debug for embedded control in battery-powered industrial sensors and motor drives.
For engineers reviewing the R5F10ELEAFB#X0 datasheet, R5F10ELEAFB#X0 pinout, R5F10ELEAFB#X0 application, or R5F10ELEAFB#X0 equivalent, key selection criteria include its 64-pin LFQFP package, 32 MHz max CPU frequency (41 DMIPS), 1.6–3.6 V supply range, 64 KB code flash with self-programming, and support for 28 analog inputs with 3.375 µs conversion time.
Technical Context
The R5F10ELEAFB#X0 implements the RL78 16-bit CISC Harvard architecture with 3-stage pipeline, enabling 86% of instructions in 1–2 clock cycles. It features dual-clock domains: high-speed on-chip oscillator (32 MHz ±1% over voltage/temperature) and subsystem crystal oscillator (32.768 kHz).
Its peripheral set includes eight 16-bit timer channels, one real-time clock with full calendar/alarm, two programmable buzzer/clock outputs, and three serial array units supporting up to six total communication interfaces - including UART, simplified SPI (CSI), and I²C - all configurable via peripheral I/O redirection registers.
