Renesas R5F10FMEAFB#V0

Overview

R5F10FMEAFB#V0 from Renesas Electronics is an RL78/G1E-series 16-bit microcontroller with integrated smart analog functions, featuring 128 KB flash memory, 8 KB RAM, and a 32 MHz max CPU clock. It includes a 12-bit ADC (12 channels), dual 10-bit DACs, programmable gain amplifier (PGA), and hardware multiplier - deployed in industrial sensor signal conditioning and closed-loop motor control systems.

For engineers reviewing the R5F10FMEAFB#V0 datasheet, R5F10FMEAFB#V0 pinout, R5F10FMEAFB#V0 application, or R5F10FMEAFB#V0 equivalent, key selection criteria include its 80-pin LQFP package, on-chip voltage regulator (LDO), temperature sensor output, and support for single-cycle multiplication - critical for real-time analog-digital co-processing in space-constrained embedded designs.

Technical Context

The R5F10FMEAFB#V0 implements the RL78 CPU core with 16-bit CISC architecture, supporting 1.6–5.5 V operation and ultra-low-power modes (HALT, STOP, SNOOZE) down to 0.54 µA. Its analog subsystem integrates a 4-channel programmable multiplexer feeding a shared 12-bit SAR ADC with configurable sampling time and window comparator.

Dedicated analog peripherals include two independent 10-bit DACs with buffer outputs, a rail-to-rail PGA with gain settings from 1× to 32×, and a built-in bandgap reference (1.45 V) with BGR_OUT pin. All analog blocks share AVDD/AVSS power domains and are synchronized via internal CLK_SYNCH and SYNCH_OUT signals.

FAQ

What is the maximum operating frequency of the R5F10FMEAFB#V0?

The R5F10FMEAFB#V0 supports a maximum CPU clock frequency of 32 MHz, achievable using the on-chip high-speed oscillator (HOCO) or external crystal input. This frequency is maintained across the full 1.6–5.5 V supply range and industrial temperature grade (–40°C to +85°C), enabling deterministic real-time performance for control algorithms and analog sampling routines in the R5F10FMEAFB#V0.

Does the R5F10FMEAFB#V0 include an integrated voltage regulator?

Yes, the R5F10FMEAFB#V0 features an integrated low-dropout regulator (LDO) that outputs a stable 3.3 V from the main VDD supply. The LDO_OUT pin provides up to 50 mA and powers internal analog circuits (ADC, DAC, PGA) as well as optional external components - reducing external component count and improving power supply rejection for sensitive analog measurements in the R5F10FMEAFB#V0.

How many analog input channels does the R5F10FMEAFB#V0 support?

The R5F10FMEAFB#V0 supports 12 analog input channels via its integrated 12-bit SAR ADC. These channels are accessible through dedicated pins MPXIN10–MPXIN61 and can be configured for single-ended or differential operation using the on-chip 4-channel analog multiplexer. This channel count and flexibility allow the R5F10FMEAFB#V0 to directly interface with multiple sensors without external signal routing.

Is the R5F10FMEAFB#V0 pin-compatible with other RL78/G1E variants?

Yes, the R5F10FMEAFB#V0 is pin-compatible with all 80-pin RL78/G1E devices including R5F10FMDAFB#V0 and R5F10FLGAFB#V0. They share identical 80-pin LQFP packaging, pin functions, and peripheral mappings - enabling hardware reuse and firmware scalability across memory variants while maintaining mechanical and electrical compatibility in the R5F10FMEAFB#V0 design.

What analog peripherals are integrated into the R5F10FMEAFB#V0?

The R5F10FMEAFB#V0 integrates a 12-bit ADC (12 channels), two 10-bit buffered DACs (DAC1_OUT, DAC2_OUT), a programmable gain amplifier (PGA) with 1×–32× gain, a factory-calibrated temperature sensor (TEMP_OUT), and a bandgap reference (BGR_OUT). These peripherals operate from dedicated AVDD/AGND domains and are synchronized via internal clock signals - forming a complete analog subsystem within the R5F10FMEAFB#V0.
