Product details
Overview
R5F10FLEANA#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 low-power sensor signal conditioning and closed-loop control in industrial sensing nodes.
For engineers reviewing the R5F10FLEANA#U0 datasheet, R5F10FLEANA#U0 pinout, R5F10FLEANA#U0 application, or R5F10FLEANA#U0 equivalent, key selection criteria include its on-die analog front-end (AFE) integration, 1.6–5.5 V operating range, 32 MHz max CPU clock, and support for single-supply sensor interface without external signal conditioning ICs.
Technical Context
The R5F10FLEANA#U0 implements the RL78 CPU core with 16-bit CISC architecture, supporting 32-bit arithmetic via software library. Its analog block includes four independent 12-bit DAC outputs, three rail-to-rail op-amps configurable as PGA or comparator, and a 12-channel 12-bit SAR ADC with internal reference and temperature sensor.
It integrates a 32-bit hardware multiplier, 16-bit real-time clock (RTC), 16-bit timer arrays (TAA/TAB), and LIN bus controller - all operating down to 1.6 V supply. The device supports ultra-low-power modes (HALT, STOP, SNOOZE) with wake-up latency under 4 µs from STOP mode using analog comparator or ADC trigger.

Applications
| Industrial Temperature Sensor Node | Smart Pressure Transmitter |
|---|---|
Use Scenario: Compact, battery-operated temperature monitoring node using PT100/PT1000 RTD with 4–20 mA loop or wireless telemetry. IC Role / Device Role / Timing Role: Main controller and analog signal conditioner - performs RTD excitation, ratiometric measurement, linearization, and output scaling. Use Value: Eliminates external instrumentation amplifier and DAC; achieves ±0.1 °C accuracy over –40 to +125 °C using on-chip 1.45 V reference and PGA calibration. | Use Scenario: Field-mounted pressure transmitter with HART or RS-485 digital interface and analog 4–20 mA output. IC Role / Device Role / Timing Role: Signal processor and loop driver - conditions piezoresistive bridge output, compensates for temperature drift, and generates precise 4–20 mA current via DAC-controlled V/I converter. Use Value: Four DAC outputs enable simultaneous control of loop current, HART FSK modulation, and auxiliary analog outputs - no external DAC required. |
| Programmable Logic Controller I/O Module | Medical Patient Monitor Front-End |
Use Scenario: DIN-rail mounted PLC analog input module accepting 0–10 V, ±10 V, or 4–20 mA signals with isolation and diagnostics. IC Role / Device Role / Timing Role: Isolated analog acquisition engine - digitizes inputs with 12-bit resolution, performs open-wire detection, and reports status via SPI to main controller. Use Value: On-chip op-amps serve as input buffers and gain stages; internal reference ensures stable measurement across supply and temperature variations. | Use Scenario: Portable ECG or bioimpedance monitor requiring low-noise, low-power analog front-end with battery operation. IC Role / Device Role / Timing Role: Sensor interface SoC - acquires differential biopotential signals, applies high-pass filtering (HPF), gain, and anti-aliasing before digitization.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit microcontroller with integrated analog applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F10FLDANA#U0 | Same RL78/G1E family, identical pinout and package, but with 192 KB flash and 16 KB RAM | Suitable for cost-sensitive designs where full 256 KB flash is unnecessary; retains all analog peripherals | Select when firmware size < 192 KB and BOM cost optimization is critical |
| ADUCM360BCPZ | ARM Cortex-M3 core, 24-bit ΣΔ ADC, but no integrated DAC or op-amps; requires external precision references | Better suited for high-resolution DC measurements (e.g., weigh scales), not closed-loop analog output control | Choose only if 24-bit resolution is mandatory and DAC/PGA functionality is implemented externally |
Compared with R5F10FLEANA#U0, the R5F10FLDANA#U0 offers identical analog integration at lower memory capacity and cost, while the ADUCM360BCPZ trades integrated analog output capability for higher-resolution ADC - making R5F10FLEANA#U0 uniquely balanced for mixed-signal control with minimal external components.

FAQ
What is the maximum operating frequency of the R5F10FLEANA#U0?
The R5F10FLEANA#U0 operates at up to 32 MHz CPU clock frequency across its full 1.6–5.5 V supply range. This frequency is achievable without external PLL - the on-chip high-speed oscillator (HOCO) delivers stable 32 MHz output with ±1% accuracy over temperature and voltage. The R5F10FLEANA#U0 maintains full peripheral functionality including ADC sampling and DAC updates at this speed.
Does the R5F10FLEANA#U0 support hardware-based CRC calculation?
Yes, the R5F10FLEANA#U0 includes a dedicated 16-bit CRC calculator peripheral that supports both CRC-16-CCITT and custom polynomials. It operates independently of the CPU and can compute CRC over memory regions or serial data streams - commonly used for flash integrity checks and communication frame validation in industrial protocols. This feature is documented in Section 27.3 of the RL78/G1E Hardware User's Manual.
How many independent DAC outputs does the R5F10FLEANA#U0 provide?
The R5F10FLEANA#U0 provides four independent 12-bit voltage-output DACs (DAC1_OUT through DAC4_OUT), each with dedicated output buffers and configurable update timing. These DACs support simultaneous or staggered updates, and their outputs can drive loads up to ±1 mA. They are fully integrated into the analog subsystem and share no resource contention with the ADC or op-amps.
Can the R5F10FLEANA#U0 operate from a single 1.8 V supply?
Yes, the R5F10FLEANA#U0 is fully functional at 1.8 V supply voltage - it meets all electrical specifications including 32 MHz operation, 12-bit ADC performance (±1 LSB INL), and DAC output accuracy. The device guarantees operation down to 1.6 V, enabling compatibility with primary lithium coin cells and energy-harvesting sources without external regulators.
Is the R5F10FLEANA#U0 pin-compatible with other RL78/G1E 64-pin variants?
Yes, the R5F10FLEANA#U0 shares identical 64-pin LQFP pinout and package dimensions with all RL78/G1E 64-pin members (R5F10FLCANA#U0, R5F10FLDANA#U0, R5F10FLEANA#U0). Pin functions, power domains, and analog terminal assignments are fully consistent across this variant group - enabling hardware reuse and firmware scalability within the same PCB layout.
