Product details
Overview
R5F1008DALA#U0 from Renesas is a 25-pin WFLGA-packaged 16-bit RL78/G13 microcontroller with 48 KB flash, 4 KB data flash, and 3 KB RAM, 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), 10-bit ADC (26 channels), and real-time clock - deployed in battery-powered industrial sensors and smart metering endpoints.
For engineers reviewing the R5F1008DALA#U0 datasheet, R5F1008DALA#U0 pinout, R5F1008DALA#U0 application, or R5F1008DALA#U0 equivalent, key selection criteria include its 25-pin WFLGA-0.5 mm pitch package, integrated data flash rewrite capability (1M cycles), 32 MHz high-accuracy on-chip oscillator (±1.0%), and industrial-grade −40°C to +85°C operation with LVD and POR.
Technical Context
The R5F1008DALA#U0 implements the RL78 CPU core with CISC architecture and 3-stage pipeline, supporting instruction execution times from 0.03125 μs (32 MHz) to 30.5 μs (32.768 kHz). It integrates dual-clock domains: high-speed main system clock and low-speed subsystem clock for independent RTC and watchdog operation.
Its peripheral set includes 2–4 channel DMA, 8–16-channel 16-bit timers, 3–10-channel I²C/Simplified I²C, 2–4-channel UART/LIN, and 2–8-channel CSI (SPI-compatible serial interface), all accessible via configurable GPIO with N-ch open-drain, TTL input, and pull-up options - enabling mixed-voltage interfacing (1.8/2.5/3.0 V).

FAQ
What is the maximum operating frequency and associated performance of the R5F1008DALA#U0?
The R5F1008DALA#U0 operates at up to 32 MHz with a peak performance of 41 DMIPS. Its high-accuracy on-chip oscillator maintains ±1.0% tolerance across −20°C to +85°C and 1.8 V to 5.5 V supply, eliminating need for external crystal in many timing-critical applications. This frequency enables real-time response in motor control and sensor sampling loops without external clock components.
Does the R5F1008DALA#U0 support in-system programming and data retention during power loss?
Yes, the R5F1008DALA#U0 supports full in-system programming via on-chip debug interface and includes background operation (BGO) for data flash writes - allowing program execution from code flash while rewriting 4 KB of data flash. Its 1,000,000-cycle endurance and VDD = 1.8–5.5 V rewrite voltage range ensure reliable logging even during brown-out conditions when paired with LVD monitoring.
How does the R5F1008DALA#U0 manage ultra-low-power operation in battery-powered applications?
The R5F1008DALA#U0 achieves 0.57 μA in STOP mode with only RTC and LVD active, and 66 μA/MHz in HALT mode. Its SNOOZE mode enables fast wake-from-sleep (<3.5 μs) for periodic sensor reads, while programmable LVD thresholds (14 levels) prevent undervoltage corruption. These features make R5F1008DALA#U0 ideal for 10-year coin-cell deployments in remote monitoring systems.
What analog capabilities does the R5F1008DALA#U0 provide for sensor interfacing?
The R5F1008DALA#U0 integrates a 10-bit ADC with up to 26 input channels, selectable internal 1.45 V reference, and an on-chip temperature sensor usable for system-level compensation. It supports simultaneous sampling across multiple channels and includes hardware averaging - enabling high-accuracy readings from thermistors, pressure bridges, or current shunts without external signal conditioning in most cases.
Is the R5F1008DALA#U0 pin-compatible with other RL78/G13 variants in the same package family?
Yes, all 25-pin WFLGA variants in the RL78/G13 family - including R5F1008DALA#U0, R5F1008EALA#U0, and R5F1008AGLA#U0 - share identical pinout, electrical characteristics, and mechanical footprint. Firmware and PCB design are interchangeable across these parts; differences are limited to flash size (48 KB vs 64 KB), data flash configuration, and temperature grade (D vs G).
