It integrates UART, I²C, SPI, LIN, RTC, PWM, and on-chip debug for embedded control in industrial sensor nodes and battery-powered HMI.

For engineers reviewing the R5F10ELEAFB#V0 datasheet, R5F10ELEAFB#V0 pinout, R5F10ELEAFB#V0 application, or R5F10ELEAFB#V0 equivalent, key selection criteria include its 64-pin LFQFP package, 32 MHz max CPU frequency (41 DMIPS), 1.6–3.6 V supply range, −40 °C to +105 °C extended temperature grade, and integrated safety features compliant with IEC/UL 60730.

Technical Context

The R5F10ELEAFB#V0 implements the RL78 16-bit CISC Harvard architecture with 3-stage pipeline, executing 86% of instructions in 1–2 clock cycles. It supports dual-clock domains: high-speed main system clock (up to 32 MHz via on-chip oscillator or external crystal) and low-speed subsystem clock (32.768 kHz for RTC).

Its peripheral set includes eight 16-bit timer channels, two programmable buzzer/clock outputs, DMA controller with two channels, and flexible I/O redirection via PIOR register - enabling dynamic pin function assignment without hardware changes.

FAQ

What is the maximum operating frequency and corresponding DMIPS rating of the R5F10ELEAFB#V0?

The R5F10ELEAFB#V0 operates at a maximum frequency of 32 MHz using its high-speed on-chip oscillator, delivering 41 DMIPS performance. This benchmark reflects actual instruction throughput under typical conditions and is validated in Renesas' official documentation (R01DS0151EJ0230 Rev.2.30). The RL78 core achieves this via a 3-stage pipeline and 86% single-cycle instruction execution.

Does the R5F10ELEAFB#V0 support hardware CRC calculation for flash integrity verification?

Yes, the R5F10ELEAFB#V0 includes a dedicated on-chip CRC calculation engine compliant with IEC/UL 60730 safety standards. It can compute CRC over any address range in code flash or data flash, enabling runtime verification of firmware integrity and safe bootloader operations - a feature explicitly documented in Section 1.1 "Features" and Chapter 26 of the R01DS0151EJ0230 datasheet.

What are the supported low-power modes and their typical current consumption for the R5F10ELEAFB#V0?

The R5F10ELEAFB#V0 supports Stop (0.23 µA RAM-retained), Halt (0.57 µA with RTC+LVD), and Snooze (0.6–0.7 mA for ADC/UART). These values are measured at VDD = 3.0 V and TA = 25 °C per R01DS0151EJ0230 Rev.2.30, Table 1.1. All modes retain RAM content and allow wake-up via external interrupt or RTC alarm.

How many analog input channels does the R5F10ELEAFB#V0 provide, and what is the ADC resolution and conversion time?

The R5F10ELEAFB#V0 provides 28 analog input channels (ANI0–ANI30) with a 12-bit successive-approximation ADC. Its conversion time is 3.375 µs per sample, and it supports internal voltage reference (1.45 V) and AVREFP/AVREFM inputs. These specifications are confirmed in Section 1.1 "Features" and Table 1.6 of the R01DS0151EJ0230 datasheet.

What is the purpose of the EVDD0 and EVSS0 pins on the R5F10ELEAFB#V0, and how should they be connected?

The EVDD0 and EVSS0 pins provide dedicated power and ground for port I/O circuits to reduce noise coupling into analog sections. Per R01DS0151EJ0230 Rev.2.30 Section 1.3.4, EVDD0 must be at a higher potential than VDD, and EVSS0 must match VSS potential. Best practice is separate power plane routing with star grounding - especially critical in mixed-signal applications like sensor nodes using the R5F10ELEAFB#V0.
