Product details
Overview
R5F1008AALA#U0 from Renesas is a 25-pin WFLGA-packaged RL78/G13 16-bit microcontroller with 16 KB flash, 2 KB RAM, and 4 KB data flash, operating from 1.6 V to 5.5 V at up to 32 MHz (41 DMIPS), featuring ultra-low-power HALT/STOP/SNOOZE modes (0.57 μA RTC+LVD), integrated 10-bit ADC (26-channel), real-time clock, and UART/I²C/CSI interfaces - deployed in battery-powered sensor nodes and industrial control panels.
For engineers reviewing the R5F1008AALA#U0 datasheet, R5F1008AALA#U0 pinout, R5F1008AALA#U0 application, or R5F1008AALA#U0 equivalent, key selection criteria include its 3×3 mm WFLGA-25 package, -40°C to +85°C A-grade temperature range, on-chip debug support, self-programmable flash with boot swap, and compatibility with Renesas' e² studio and CS+ toolchains.
Technical Context
The R5F1008AALA#U0 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting instruction execution times from 0.03125 μs (32 MHz high-speed mode) to 30.5 μs (32.768 kHz subsystem clock). It integrates a 12-bit interval timer, calendar-based RTC with alarm and correction, and a watchdog timer driven by a dedicated low-speed oscillator.
Its peripheral set includes up to 26 analog input channels for the 10-bit ADC, 3–10 I²C/Simplified I²C channels, 2–4 UART/LIN channels, and 2–8 CSI (SPI-compatible) channels - all configurable via register-level control without external glue logic.
