Renesas R5F10FMEDFB#X0

Overview

R5F10FMEDFB#X0 from Renesas Electronics is an RL78/G1E-series 16-bit microcontroller with integrated smart analog functions, featuring 128 KB flash, 8 KB RAM, and a 32 MHz max CPU clock. It includes a 12-bit ADC (12 channels), 12-bit DAC (4 channels), programmable gain amplifier (PGA), and hardware multiplier - deployed in industrial sensor signal conditioning and closed-loop motor control systems.

For engineers reviewing the R5F10FMEDFB#X0 datasheet, R5F10FMEDFB#X0 pinout, R5F10FMEDFB#X0 application, or R5F10FMEDFB#X0 equivalent, key selection criteria include its 80-pin LQFP package, on-chip analog front-end for single-supply sensor interfacing, low-power operation down to 0.52 mA/MHz in HALT mode, and support for I²C, CSI, UART, and LIN protocols.

Technical Context

The R5F10FMEDFB#X0 implements the RL78 CPU core with 16-bit CISC architecture, 3-stage pipeline, and 16 MB linear address space. It integrates a dedicated analog subsystem comprising four independent 12-bit DACs, a 12-bit SAR ADC with selectable sample-and-hold, and a rail-to-rail PGA with 1×–128× programmable gain.

Its peripheral set includes a 16-bit timer array unit (TAU) with complementary PWM output, a serial interface (CSI) supporting SPI-like operation, and a LIN bus controller compliant with ISO 17987-4. All analog and digital I/O are referenced to separate AVDD/AVSS and DVDD/DGND domains for noise isolation.

FAQ

What is the maximum operating frequency of the R5F10FMEDFB#X0?

The R5F10FMEDFB#X0 operates at a maximum CPU clock frequency of 32 MHz, achievable using the on-chip high-speed oscillator (HOCO) or external crystal input. This speed supports real-time execution of control algorithms and communication stacks without external clocking components in most industrial applications.

Does the R5F10FMEDFB#X0 support hardware-based LIN communication?

Yes, the R5F10FMEDFB#X0 includes a dedicated LIN bus controller compliant with LIN 2.2 and SAE J2602 standards. It supports automatic baud rate detection, checksum calculation, and frame timeout handling - enabling robust LIN slave node implementation without consuming CPU cycles for protocol management.

How many analog-to-digital converter (ADC) channels does the R5F10FMEDFB#X0 have?

The R5F10FMEDFB#X0 features a 12-bit SAR ADC with 12 multiplexed input channels (MPXIN10–MPXIN61), supporting both single-ended and differential configurations. These channels feed into a shared conversion engine with 1.0 μs typical conversion time, allowing rapid sampling across multiple sensors.

What is the purpose of the GAINAMP_IN and GAINAMP_OUT pins on the R5F10FMEDFB#X0?

The GAINAMP_IN and GAINAMP_OUT pins provide direct access to the on-chip programmable gain amplifier (PGA), which offers selectable gains from 1× to 128× in binary steps. This allows signal-level adjustment prior to ADC sampling - critical for optimizing dynamic range when interfacing low-amplitude sensors like thermopiles or strain gauges.

Is the R5F10FMEDFB#X0 pin-compatible with other RL78/G1E 80-pin variants?

Yes, the R5F10FMEDFB#X0 shares identical 80-pin LQFP mechanical and electrical pinout with all RL78/G1E 80-pin members (e.g., R5F10FMC, R5F10FMD). This enables hardware reuse across firmware variants - for example, upgrading from 64 KB to 128 KB flash without PCB redesign.
