Renesas R5F100LEDFB#V0

Overview

R5F100LEDFB#V0 from Renesas is a 64-pin LFQFP-0.5mm-pitch 16-bit RL78/G13 microcontroller with 128 KB flash, 8 KB data flash, 12 KB RAM, and ultra-low-power operation (66 μA/MHz active, 0.57 μA RTC+LVD). It integrates 16-bit timers, 10-bit ADC (26 channels), UART/SPI/I²C interfaces, and real-time clock - deployed in industrial sensor nodes and battery-powered control modules.

For engineers reviewing the R5F100LEDFB#V0 datasheet, R5F100LEDFB#V0 pinout, R5F100LEDFB#V0 application, or R5F100LEDFB#V0 equivalent, key selection criteria include its 64-pin LFQFP package, -40°C to +85°C industrial temperature grade (D), integrated data flash for parameter storage, low-voltage operation down to 1.6 V, and RL78 CPU core delivering 41 DMIPS at 32 MHz.

Technical Context

The R5F100LEDFB#V0 implements the RL78 CISC CPU core with 3-stage pipeline and configurable instruction timing (0.03125 μs min @ 32 MHz, 30.5 μs @ 32.768 kHz). It supports multiple low-power modes - HALT, STOP, and SNOOZE - enabling dynamic power scaling across duty-cycled applications.

Its peripheral set includes dual DMA channels (2-clock transfer latency), hardware multiplier/divider/MAC, background data flash rewriting (BGO), and on-chip voltage detector with 14-level LVD interrupt/reset selection - all operating within 1.6–5.5 V supply range and validated for industrial ambient temperatures (-40°C to +85°C).

FAQ

What is the maximum operating frequency and corresponding DMIPS rating of the R5F100LEDFB#V0?

The R5F100LEDFB#V0 operates at up to 32 MHz with its high-speed on-chip oscillator, delivering 41 DMIPS of processing performance. This benchmark reflects the RL78 CPU core's 3-stage pipeline efficiency and is measured under standard conditions per Renesas documentation R01DS0131EJ0380. The R5F100LEDFB#V0 maintains this performance across its full 1.6–5.5 V supply range and -40°C to +85°C temperature grade.

Does the R5F100LEDFB#V0 include on-chip data flash memory, and what is its endurance specification?

Yes, the R5F100LEDFB#V0 integrates 8 KB of on-chip data flash memory, supporting background operation (BGO) for concurrent code execution and data rewriting. Its endurance is rated at 1,000,000 write/erase cycles (typical), with rewrite voltage compatibility across the full 1.8–5.5 V VDD range. This capability is confirmed in the RL78/G13 datasheet section 1.1 Features and applies specifically to the R5F100LEDFB#V0 variant.

What low-power modes does the R5F100LEDFB#V0 support, and what is its lowest current consumption?

The R5F100LEDFB#V0 supports HALT, STOP, and SNOOZE low-power modes. In STOP mode with only the real-time clock (RTC) and low-voltage detector (LVD) active, it achieves 0.57 μA typical current consumption - verified in the datasheet's "Ultra-low power consumption technology" section. This value is guaranteed over the full -40°C to +85°C industrial temperature range and enables multi-year operation on coin-cell or AA batteries.

Is the R5F100LEDFB#V0 pin-compatible with other RL78/G13 64-pin variants, and what package type does it use?

Yes, the R5F100LEDFB#V0 uses the 64-pin LFQFP package (10 mm × 10 mm, 0.5 mm pitch, FB suffix), and shares identical pinout with other RL78/G13 64-pin LFQFP variants such as R5F100LGDFB#V0 and R5F101LEDFB#V0. Pin compatibility is confirmed by Renesas' package outline PLQP0064KF-A and ordering part number structure - the "FB" and "#V0" denote consistent LFQFP-0.5mm-tray configuration.

What serial communication interfaces are integrated into the R5F100LEDFB#V0, and how many channels does each support?

The R5F100LEDFB#V0 integrates three serial interface types: Simplified SPI (CSI) with up to 8 channels, UART/LIN with up to 4 channels, and I²C/Simplified I²C with up to 10 channels. Channel counts are determined by pin multiplexing and resource allocation within the RL78/G13 architecture - the R5F100LEDFB#V0's 64-pin package supports the upper end of these ranges, as documented in Table 1-1 and Section 1.1 of the datasheet.
