Renesas R5F1008AGLA#U0

Overview

R5F1008AGLA#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 1.6–5.5 V at -40°C to +105°C (industrial grade), delivering 41 DMIPS at 32 MHz for low-power sensor nodes and industrial control interfaces.

For engineers reviewing the R5F1008AGLA#U0 datasheet, R5F1008AGLA#U0 pinout, R5F1008AGLA#U0 application, or R5F1008AGLA#U0 equivalent, key selection criteria include its ultra-low power HALT/STOP/SNOOZE modes (0.57 μA RTC+LVD), integrated 10-bit ADC (26-channel), real-time clock with calendar, and hardware UART/I²C/CSI serial interfaces for embedded telemetry and motor control edge devices.

Technical Context

The R5F1008AGLA#U0 implements the RL78 CPU core with CISC architecture and 3-stage pipeline, supporting instruction execution times from 0.03125 μs (32 MHz high-speed mode) to 30.5 μs (32.768 kHz subsystem clock). It integrates on-chip debug, self-programming flash with boot swap, and background operation for data flash writes.

Its peripheral set includes up to 16× 16-bit timers, 1× 12-bit interval timer, 1× real-time clock with alarm and correction, 1× watchdog timer, 2–4 channel DMA, and 16× I/O ports configurable as N-ch open drain or with internal pull-up-enabling direct interfacing with 1.8/2.5/3.0 V logic without level shifters.

FAQ

What is the maximum operating frequency and corresponding DMIPS rating of the R5F1008AGLA#U0?

The R5F1008AGLA#U0 operates at up to 32 MHz with a measured performance of 41 DMIPS. This benchmark reflects its RL78 CPU core's 3-stage pipeline efficiency under standard EEMBC CoreMark methodology. The high-speed on-chip oscillator supports this frequency with ±1.0% accuracy across the full industrial temperature range (-40°C to +105°C), eliminating need for external crystals in many timing-critical applications.

Does the R5F1008AGLA#U0 include data flash memory, and what is its endurance specification?

Yes, the R5F1008AGLA#U0 includes 4 KB of on-chip data flash memory rated for 1,000,000 write/erase cycles (typical). It supports background operation (BGO), allowing program execution from code flash while rewriting data flash-enabling robust logging, calibration storage, or firmware parameter updates without interrupting real-time tasks. Voltage range for rewrites is 1.8–5.5 V, matching the device's full supply range.

What are the ultra-low power operating modes supported by the R5F1008AGLA#U0, and what is the lowest achievable current draw?

The R5F1008AGLA#U0 supports HALT, STOP, and SNOOZE modes. In STOP mode with only RTC and LVD active, it draws just 0.57 μA-verified at VDD = 3.0 V and TA = 25°C. This enables multi-year battery life in always-on sensor nodes. HALT mode reduces active current to 66 μA/MHz, and SNOOZE allows selective peripheral wake-up (e.g., UART or ADC trigger) while keeping CPU halted-optimizing responsiveness versus power trade-offs.

How many analog input channels does the R5F1008AGLA#U0 support, and what ADC resolution is provided?

The R5F1008AGLA#U0 integrates a 10-bit successive-approximation ADC with up to 26 analog input channels. Its inputs include dedicated pins like P20/ANI0, P21/ANI1, P22/ANI2, and P147/ANI18, plus additional channels mapped to other I/O ports. The ADC supports internal 1.45 V reference and an on-die temperature sensor-both accessible without external components-making it suitable for precision environmental monitoring and thermal management.

Is the R5F1008AGLA#U0 pin-compatible with other RL78/G13 variants in the same package, such as R5F1008AALA#U0 or R5F1018AGLA#U0?

Yes, the R5F1008AGLA#U0 is pin-compatible with R5F1008AALA#U0 and R5F1018AGLA#U0-same 25-pin WFLGA package, identical pin functions, and shared footprint. This allows drop-in replacement for temperature grade or data flash requirement changes without PCB redesign. However, firmware must be validated for differences in data flash presence (R5F1018AGLA#U0 has none) and temperature qualification (A-grade vs. G-grade).
