For engineers reviewing the R5F10ELEGFB#V0 datasheet, R5F10ELEGFB#V0 pinout, R5F10ELEGFB#V0 application, or R5F10ELEGFB#V0 equivalent, key selection criteria include its 0.57 µA RTC+LVD halt current, 66 µA/MHz active power, 32 MHz max CPU frequency, 48-pin-compatible peripheral set, and IEC 60730 safety features for certified embedded control.

Technical Context

The R5F10ELEGFB#V0 implements the RL78 16-bit CISC Harvard architecture with 3-stage pipeline, delivering 41 DMIPS at 32 MHz; it supports single-cycle 16×16 multiply and 2-cycle MAC operations, plus 1-wire on-chip debug.

It integrates dual-clock domains: high-speed on-chip oscillator (32 MHz ±1% over 1.8–3.6 V and −20 to +85 °C) and subsystem crystal oscillator (32.768 kHz), with independent voltage domains (VDD/EVDD0, VSS/EVSS0) for noise-sensitive analog and digital operation.

FAQ

What is the maximum operating frequency and core performance of the R5F10ELEGFB#V0?

The R5F10ELEGFB#V0 operates at up to 32 MHz using its high-speed on-chip oscillator and delivers 41 DMIPS. Its RL78 16-bit CPU core executes 86% of instructions in 1–2 clock cycles, supports single-cycle 16×16 multiply, and includes a 16-bit barrel shifter-all confirmed in the R01DS0151EJ0230 datasheet. This performance level enables real-time control loops in motor and sensor applications without external acceleration.

Does the R5F10ELEGFB#V0 support functional safety standards like IEC 60730?

Yes, the R5F10ELEGFB#V0 includes multiple hardware safety features required for IEC/UL 60730 Class B compliance: flash memory CRC calculation, RAM parity error detection, SFR write protection, illegal memory access trapping, clock stop/frequency monitoring, and ADC self-test. These are documented in Section 1.1 Features and Chapter 22 of the R01DS0151EJ0230 datasheet and are active in the industrial-grade G-suffix variant.

What are the power consumption modes supported by the R5F10ELEGFB#V0?

The R5F10ELEGFB#V0 supports five defined power modes: Operating (66 µA/MHz), Snooze (0.6–0.7 mA for ADC/UART), Halt (0.57 µA with RTC + LVD), Stop (0.23–0.31 µA), and Deep Stop (0.19 µA with optional RAM retention). All values are measured at VDD = 3.0 V and TA = 25 °C per Section 1.1 of the R01DS0151EJ0230 datasheet and apply to the industrial-grade R5F10ELEGFB#V0 variant.

How many analog input channels and what ADC resolution does the R5F10ELEGFB#V0 provide?

The R5F10ELEGFB#V0 integrates a 28-channel, 12-bit successive approximation register (SAR) ADC with 3.375 µs conversion time and support for 1.6 V minimum supply voltage. It includes internal 1.45 V voltage reference and on-chip temperature sensor. These specifications are fixed for the 64-pin RL78/G1A family member R5F10ELEGFB#V0 and verified in Table 1-1 and Section 1.1 of the R01DS0151EJ0230 datasheet.

What is the purpose of the EVDD0 and EVSS0 pins on the R5F10ELEGFB#V0?

The EVDD0 and EVSS0 pins on the R5F10ELEGFB#V0 provide dedicated power and ground for port I/O circuits, enabling physical separation from the core VDD/VSS domain. This reduces digital switching noise coupling into analog peripherals (ADC, RTC, oscillators). Per Section 1.3.4 and Cautions on Page 9 of R01DS0151EJ0230, EVSS0 must be tied to VSS, and VDD must exceed EVDD0 potential-critical for achieving specified ADC accuracy and oscillator stability in industrial environments.
