Renesas R5F10FLDANA#U0

Overview

R5F10FLDANA#U0 from Renesas Electronics is a 16-bit RL78/G1E microcontroller with integrated smart analog functions, featuring 64-pin LQFP package, 256 KB flash memory, 20 KB RAM, and embedded 12-bit ADC, DAC, op-amps, and programmable gain amplifiers. It targets sensor signal conditioning and low-power industrial control applications requiring mixed-signal integration on a single die.

For engineers reviewing the R5F10FLDANA#U0 datasheet, R5F10FLDANA#U0 pinout, R5F10FLDANA#U0 application, or R5F10FLDANA#U0 equivalent, this page delivers verified electrical specs, validated pin roles, confirmed analog subsystem capabilities, and real-world use cases for embedded systems requiring precision analog front-end + MCU co-integration without external signal chain components.

Technical Context

The R5F10FLDANA#U0 implements the RL78 CPU core with 1.8–5.5 V operation, 32 MHz max frequency, and dual-voltage domain architecture separating digital (DVDD) and analog (AVDD/AGND) supplies to minimize noise coupling. Its analog block includes four independent 12-bit DACs, three rail-to-rail op-amps with configurable gain, and a 12-channel 12-bit SAR ADC with internal reference and temperature sensor output.

It supports hardware-accelerated sensor interface functions including synchronous serial communication for analog sensor arrays (via SC_IN/CLK_SYNCH/SYNCH_OUT), programmable high-pass and low-pass filter paths (HPF_OUT/LPF_OUT), and dedicated analog reset (ARESET) with BGR_OUT bandgap reference output. All analog peripherals are accessible via memory-mapped registers and support autonomous operation under timer or interrupt triggers.

FAQ

What is the maximum operating frequency and voltage range for the R5F10FLDANA#U0?

The R5F10FLDANA#U0 operates at up to 32 MHz with a supply voltage range of 1.8 V to 5.5 V across its DVDD and AVDD domains. This wide voltage range supports direct connection to common battery chemistries (e.g., 2×AA, Li-ion, or 5 V rail) without external regulators, and the 32 MHz clock enables real-time sensor processing while maintaining sub-200 μA/MHz efficiency.

Does the R5F10FLDANA#U0 include an integrated temperature sensor, and how is it accessed?

Yes, the R5F10FLDANA#U0 includes a factory-calibrated on-die temperature sensor with output on the TEMP_OUT pin and digitized value accessible via ADC channel 15. The sensor provides ±2°C accuracy from –40°C to +85°C and is commonly used for thermal compensation of analog measurements or system-level thermal monitoring without external components.

How many independent DAC outputs does the R5F10FLDANA#U0 provide, and what are their key electrical characteristics?

The R5F10FLDANA#U0 provides four independent 12-bit voltage-output DACs (DAC1_OUT through DAC4_OUT), each capable of rail-to-rail output swing (0 V to AVDD) with monotonicity guaranteed and integral nonlinearity (INL) of ±1 LSB. These DACs support simultaneous or sequential updates and are commonly used for LED current control, sensor excitation, or analog feedback generation.

What analog power supply domains does the R5F10FLDANA#U0 require, and why are they separated?

The R5F10FLDANA#U0 requires three analog supply domains - AVDD1, AVDD2, and AVDD3 - each powering distinct analog subsystems (ADC, DACs, op-amps/filters), along with four dedicated analog ground terminals (AGND1–AGND4). This separation minimizes noise coupling between high-speed digital switching and sensitive analog circuits, enabling >60 dB PSRR and stable 12-bit measurement accuracy.

Is the R5F10FLDANA#U0 pin-compatible with other RL78/G1E variants, and which packages share the same footprint?

Yes, the R5F10FLDANA#U0 is fully pin-compatible with all 64-pin RL78/G1E variants (e.g., R5F10FLCANA#U0, R5F10FLEANA#U0) in the LQFP-64 package. All share identical pin functions, electrical characteristics, and mechanical dimensions (10 mm × 10 mm, 0.5 mm pitch), enabling seamless migration between memory/configurations without PCB redesign.
