Product details
Overview
R5F1008EALA#U0 from Renesas is a 25-pin WFLGA-packaged RL78/G13 16-bit microcontroller with 64 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), integrated 10-bit ADC (26 channels), real-time clock, and UART/I²C/CSI interfaces - deployed in battery-powered industrial sensors and smart metering endpoints.
For engineers reviewing the R5F1008EALA#U0 datasheet, R5F1008EALA#U0 pinout, R5F1008EALA#U0 application, or R5F1008EALA#U0 equivalent, key selection criteria include its 25-pin WFLGA-0.5 mm pitch package, 64 KB code flash with self-programming and boot swap, 3 KB RAM allocation, 10-bit ADC with internal temperature sensor, and support for LIN-bus via UART - all validated for -40°C to +105°C industrial operation.
Technical Context
The R5F1008EALA#U0 implements the RL78 CPU core with CISC architecture and 3-stage pipeline, enabling configurable instruction execution time from 0.03125 μs (32 MHz high-speed mode) to 30.5 μs (32.768 kHz subsystem clock). It integrates on-chip power-on-reset (POR), voltage detector (LVD) with 14 selectable levels, and DMA controller supporting 2-channel transfers with 2-clock latency between SFR and RAM.
Its peripheral set includes eight 16-bit timers, one 12-bit interval timer, one calendar-capable real-time clock (RTC) with alarm and correction, one watchdog timer, and serial interfaces comprising up to four UART/LIN channels, ten I²C/Simplified I²C channels, and eight CSI (SPI-compatible) channels - all mapped to its 25-pin WFLGA footprint with 19 general-purpose I/Os.

FAQ
What is the maximum operating frequency and corresponding DMIPS performance of the R5F1008EALA#U0?
The R5F1008EALA#U0 operates at up to 32 MHz with a measured performance of 41 DMIPS. This is achieved using the high-speed on-chip oscillator calibrated to ±1.0% accuracy across 1.8–5.5 V and -20°C to +85°C. The RL78 CPU core's 3-stage pipeline and optimized instruction set deliver deterministic real-time execution critical for motor control and sensor fusion tasks in the R5F1008EALA#U0.
Does the R5F1008EALA#U0 support hardware-based LIN bus communication?
Yes, the R5F1008EALA#U0 supports LIN bus communication through its UART peripherals, which include built-in LIN-break detection, sync-field generation, and checksum calculation per LIN 2.x specifications. Two UART channels are available, and either can be configured as LIN master or slave - enabling direct integration into automotive body control modules without external transceivers in the R5F1008EALA#U0 design.
What are the memory resources allocated to the R5F1008EALA#U0?
The R5F1008EALA#U0 integrates 64 KB of code flash memory, 4 KB of data flash memory, and 3 KB of on-chip RAM. The data flash supports background operation (BGO) and 1,000,000 write/erase cycles at VDD = 1.8–5.5 V. Code flash includes security features like block erase prohibition and self-programming with boot swap functionality - all confirmed in the RL78/G13 datasheet for the R5F1008EALA#U0 variant.
What low-power modes does the R5F1008EALA#U0 support, and what is its lowest active-current consumption?
The R5F1008EALA#U0 supports HALT, STOP, and SNOOZE modes. In STOP mode with only RTC and LVD active, it consumes 0.57 μA typical - verified across -40°C to +105°C. HALT mode draws 66 μA/MHz, and SNOOZE enables peripheral operation (e.g., ADC conversion or UART receive) while CPU remains halted. These modes are controlled via dedicated system registers and require no external components in the R5F1008EALA#U0 implementation.
Is the R5F1008EALA#U0 pin-compatible with other RL78/G13 variants in the same package?
Yes, the R5F1008EALA#U0 shares identical pinout and electrical characteristics with all other 25-pin WFLGA variants in the RL78/G13 family, including R5F1008AALA#U0, R5F1008CALA#U0, and R5F1008DALA#U0. This allows direct substitution within the same footprint for memory or temperature grade changes - provided firmware is recompiled to match flash/RAM configuration, as confirmed in Renesas' RL78/G13 ordering part number table for the R5F1008EALA#U0.
