Renesas R5F1058AGLA#U0

Overview

R5F1058AGLA#U0 from Renesas Electronics is a 25-pin WFLGA-packaged 16-bit RL78/G11 microcontroller designed for ultra-low-power industrial embedded control. It delivers 33 DMIPS at 24 MHz, integrates 16 KB code flash, 2 KB data flash, and 1.5 KB RAM, and operates across 1.6–5.5 V with industrial-grade temperature range (−40°C to +105°C). It supports real-time sensor interfacing, motor control, and battery-powered HMI in smart appliances and industrial IoT edge nodes.

For engineers reviewing the R5F1058AGLA#U0 datasheet, R5F1058AGLA#U0 pinout, R5F1058AGLA#U0 application, or R5F1058AGLA#U0 equivalent, key selection criteria include its 11-channel 10-bit ADC with internal reference and temperature sensor, dual D/A converters, two comparators with window mode, and hardware event linking via ELC for deterministic peripheral coordination without CPU overhead.

Technical Context

The R5F1058AGLA#U0 implements the RL78 CISC core with 3-stage pipeline, supporting variable instruction execution time (0.04167 μs @ 24 MHz to 66.6 μs @ 15 kHz) and multiply/divide/accumulate instructions. Its clock system combines high-speed on-chip oscillator (±1.0% accuracy, 1–24 MHz), middle-speed (4/2/1 MHz), and low-speed (15 kHz) oscillators, enabling dynamic power-state transitions between HALT, STOP, and SNOOZE modes.

Peripheral integration includes four CSI channels, two UARTs, four simplified I²C interfaces, 16-bit TAU timer (4 channels), 12-bit interval timer, watchdog, and Data Transfer Controller (DTC) with 24 activation sources. The Event Link Controller (ELC) supports 18 configurable event signals linked to peripherals, enabling autonomous hardware-triggered operations.

FAQ

What is the operating voltage range and temperature grade of the R5F1058AGLA#U0?

The R5F1058AGLA#U0 operates from 1.6 V to 5.5 V and is rated for industrial temperature range (−40°C to +105°C), as indicated by the "G" suffix in the part number. Its on-chip voltage detector supports 14 programmable threshold levels for both power-on and power-down reset conditions, ensuring reliable startup and brown-out recovery across this full range.

Does the R5F1058AGLA#U0 support simultaneous analog-to-digital conversion on multiple channels?

Yes, the R5F1058AGLA#U0 features an 11-channel 10-bit A/D converter capable of sequential or group-scan conversion. It supports internal reference voltage (1.45 V), temperature sensor readout, and AVREFP/AVREFM inputs - enabling synchronized multi-sensor acquisition without external reference components.

How does the Event Link Controller (ELC) enhance real-time performance in the R5F1058AGLA#U0?

The ELC in the R5F1058AGLA#U0 allows 18 hardware events (e.g., timer match, ADC completion, comparator output) to trigger peripheral actions directly - such as starting a DTC transfer or initiating a DAC update - without CPU intervention. This reduces interrupt latency and frees the RL78 core for higher-layer tasks.

Can the R5F1058AGLA#U0 perform background data flash rewriting while executing application code?

Yes, the R5F1058AGLA#U0 supports Background Operation (BGO) for data flash memory. Instructions can be fetched and executed from program memory while the 2 KB data flash is being rewritten, enabling seamless firmware parameter updates or logging without halting system operation.

What packaging and assembly considerations apply to the R5F1058AGLA#U0's WFLGA package?

The R5F1058AGLA#U0 uses a 25-pin WFLGA package (3 × 3 mm, 0.50-mm pitch) with an exposed die pad that must be soldered to a VSS thermal pad on the PCB. The REGC pin requires a 0.47–1 μF capacitor to VSS. Renesas specifies #U0 as tray packaging - compatible with standard SMT placement and reflow profiles for fine-pitch QFN/WFLGA devices.
