Product details
Overview
R5F100LDAFB#X0 from Renesas is a 64-pin LFQFP-packaged RL78/G13 16-bit microcontroller with 128 KB flash, 8 KB data flash, 12 KB RAM, and industrial-grade operation (−40°C to +85°C). It integrates a real-time clock, 10-bit ADC (26 channels), UART/LIN, I²C, CSI, 16-bit timers, and ultra-low-power modes (0.57 μA in RTC+LVD mode) for embedded control in metering, motor drives, and industrial HMI.
For engineers reviewing the R5F100LDAFB#X0 datasheet, R5F100LDAFB#X0 pinout, R5F100LDAFB#X0 application, or R5F100LDAFB#X0 equivalent, key selection criteria include its 64-pin LFQFP-0.5mm pitch package, 128 KB code flash with self-programming, integrated LIN support, and verified operation across −40°C to +85°C industrial temperature range.
Technical Context
The R5F100LDAFB#X0 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting instruction execution times from 0.03125 μs (32 MHz high-speed mode) to 30.5 μs (32.768 kHz ultra-low-speed mode). It features dual-clock domains: high-speed on-chip oscillator (±1.0% accuracy, selectable 1–32 MHz) and dedicated low-speed oscillator for watchdog and RTC.
Its peripheral set includes 8-channel 16-bit timers, 1-channel 12-bit interval timer, calendar-mode RTC with alarm/correction, 2–4 channel DMA, and 3–10 channel I²C/Simplified I²C - all configurable via register-based control without external timing components.

FAQ
What is the maximum operating frequency and instruction throughput of the R5F100LDAFB#X0?
The R5F100LDAFB#X0 operates up to 32 MHz using its high-speed on-chip oscillator, delivering 41 DMIPS performance. Its RL78 CPU core achieves minimum instruction execution time of 0.03125 μs at 32 MHz, confirmed in the R01DS0131EJ0380 datasheet Section 1.1.
Does the R5F100LDAFB#X0 support LIN communication, and how is it implemented?
Yes, the R5F100LDAFB#X0 supports LIN 2.2 communication through its UART peripheral with built-in LIN break detection, sync field generation, and checksum calculation. This eliminates external LIN transceivers for basic node functionality, as documented in Section 1.1 "Serial interface" of the R01DS0131EJ0380 datasheet.
What is the flash memory endurance and data retention specification for the R5F100LDAFB#X0?
The R5F100LDAFB#X0 provides 128 KB code flash with 100,000 erase/write cycles (min) and 8 KB data flash rated for 1,000,000 write cycles (typical). Data retention is guaranteed for 20 years at 85°C, per Renesas specification R01DS0131EJ0380 Section 1.1.
How does the R5F100LDAFB#X0 manage low-power operation during RTC-only use?
In STOP mode with only RTC and LVD active, the R5F100LDAFB#X0 consumes just 0.57 μA (typical) at VDD = 3.0 V and TA = 25°C. This is enabled by independent clock gating and retention of RTC registers while disabling CPU, flash, and most peripherals - verified in Section 1.1 "Ultra-low power consumption technology".
Is the R5F100LDAFB#X0 pin-compatible with other RL78/G13 64-pin variants?
Yes, all RL78/G13 64-pin variants in LFQFP-0.5mm pitch (e.g., R5F100LCAFB#X0, R5F100LEAFB#X0) share identical pinout and footprint. Differences are limited to memory size and data flash presence - confirmed in Table 1-1 (Page 10) and Figure 1-1 of R01DS0131EJ0380.
