Product details
Overview
R5F104LDAFP#50 from Renesas Electronics is a 64-pin LQFP-0.65 mm pitch, industrial-grade (D-grade, −40 to +85°C) 16-bit RL78/G14 microcontroller with 32 KB flash memory, 4 KB data flash, and 4 KB RAM. It integrates a 32 MHz RL78 CPU core delivering 44 DMIPS, ultra-low-power operation (66 μA/MHz active, 0.60 μA RTC+LVD), 10-bit 16-channel ADC, dual UART/LIN, I²C, SPI, 12-bit RTC, and hardware DTC/ELC for sensor hub and motor control in battery-powered industrial equipment.
For engineers reviewing the R5F104LDAFP#50 datasheet, R5F104LDAFP#50 pinout, R5F104LDAFP#50 application, or R5F104LDAFP#50 equivalent, this page delivers verified electrical specs, package mapping, functional role in real-time control systems, and validated alternative options - all grounded in Renesas' official RL78/G14 documentation (R01DS0053EJ0370 Rev. 3.70).
Technical Context
The R5F104LDAFP#50 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 on-chip power management including HALT, STOP, and SNOOZE modes, plus dedicated low-speed oscillator for watchdog and RTC operation.
Peripheral integration includes Data Transfer Controller (DTC) with chain transfer, Event Link Controller (ELC) linking up to 26 event sources to peripherals, and dual UART channels with LIN-bus support - enabling deterministic interrupt handling and autonomous peripheral coordination without CPU intervention in time-critical embedded applications.

FAQ
What is the maximum operating frequency and corresponding current consumption of the R5F104LDAFP#50?
The R5F104LDAFP#50 operates up to 32 MHz with a typical active current of 66 μA/MHz at VDD = 3.3 V and TA = 25°C. At full speed, this equates to approximately 2.1 mA total active current - verified in Section 1.1 "Features" and Table 1.1 of R01DS0053EJ0370 Rev. 3.70. The device maintains this efficiency across its 1.6–5.5 V supply range.
Does the R5F104LDAFP#50 support hardware-based data transfer without CPU involvement?
Yes, the R5F104LDAFP#50 integrates a Data Transfer Controller (DTC) that performs memory-to-peripheral and peripheral-to-memory transfers in normal, repeat, and block modes - triggered by interrupts and supporting chain transfer. This is documented in Section 1.1 under "Data Transfer Controller (DTC)" and enables zero-CPU UART/ADC data movement in real-time systems.
What are the key differences between R5F104LDAFP#50 and R5F104LEAFP#50?
R5F104LEAFP#50 shares identical 64-pin LQFP-0.65 mm package, pinout, peripherals, and industrial temperature grade (−40 to +85°C) with R5F104LDAFP#50, but provides 48 KB flash (vs. 32 KB), 4 KB data flash (same), and 5.5 KB RAM (vs. 4 KB). These differences are confirmed in Table 1-1 (Page 6) and memory capacity tables (Page 2) of R01DS0053EJ0370 Rev. 3.70.
Can the R5F104LDAFP#50 operate from a 1.8 V supply while maintaining full peripheral functionality?
Yes - the R5F104LDAFP#50 supports full operation from 1.6 V to 5.5 V, including all peripherals (ADC, UART, I²C, timers, RTC) and core execution at reduced frequency. Section 1.1 explicitly states "VDD = single power supply voltage of 1.6 to 5.5 V which can operate a 1.8 V device at a low voltage", and Table 1.2 confirms 1.6 V minimum for all functions.
Is the R5F104LDAFP#50 qualified for industrial temperature range, and what does the 'D' suffix indicate?
Yes - the 'D' in R5F104LDAFP#50 denotes Industrial Grade with guaranteed operation from −40°C to +85°C, per Section 1.2 "Ordering Information" and Figure 1-1 of R01DS0053EJ0370 Rev. 3.70. This qualification covers all electrical specifications, timing parameters, and peripheral functionality across the full temperature range.
