Product details
Overview
R5F104LDGFA#50 from Renesas is a 64-pin LFQFP, 512 KB flash, 8 KB data flash, 48 KB RAM RL78/G14 16-bit MCU operating from 1.6–5.5 V, delivering 44 DMIPS at 32 MHz with ultra-low-power HALT/STOP/SNOOZE modes (0.60 μA RTC+LVD), targeting industrial control and sensor interface applications.
For engineers reviewing the R5F104LDGFA#50 datasheet, R5F104LDGFA#50 pinout, R5F104LDGFA#50 application, or R5F104LDGFA#50 equivalent, key selection criteria include its -40°C to +105°C industrial-grade temperature range (G suffix), 64-pin 0.5 mm pitch LFQFP package, integrated 10-bit 20-channel ADC with internal reference and temperature sensor, and dual UART/LIN support for robust serial communication in harsh environments.
Technical Context
The R5F104LDGFA#50 implements the RL78 CPU core with CISC architecture, 3-stage pipeline, and configurable instruction timing (0.03125 µs @ 32 MHz to 30.5 µs @ 32.768 kHz). It integrates a 19–26-event Event Link Controller (ELC) for peripheral event chaining and a Data Transfer Controller (DTC) supporting normal, repeat, and block transfer modes activated by interrupts.
Its mixed-signal subsystem includes an 8/10-bit ADC with up to 20 analog inputs, internal 1.45 V reference, and on-chip temperature sensor; an 8-bit DAC with up to two outputs; two comparators with window/high-speed/low-speed modes; and a calendar-equipped real-time clock with alarm and correction functions - all operating across the full industrial temperature range.

FAQ
What is the operating temperature range for the R5F104LDGFA#50?
The R5F104LDGFA#50 is rated for industrial operation from -40°C to +105°C, as indicated by the 'G' suffix in the part number. This rating applies to all specified electrical characteristics and ensures reliable performance in demanding environments such as factory automation controllers and under-hood automotive modules. The device maintains full functionality-including ADC accuracy, oscillator stability, and flash programming-across this entire range.
Does the R5F104LDGFA#50 support background data flash rewriting?
Yes, the R5F104LDGFA#50 supports Background Operation (BGO) for data flash rewriting. Its 8 KB data flash can be updated while the CPU executes code from main flash memory, enabling seamless firmware parameter storage or logging without interrupting real-time tasks. This capability requires proper configuration of the flash library and uses RAM starting at address F3F00H per the RL78/G14 documentation.
How many UART/LIN channels does the R5F104LDGFA#50 provide?
The R5F104LDGFA#50 provides four UART channels, each supporting LIN bus protocol compliance. These are implemented as UART0 through UART3, with dedicated pins including P13/TxD2, P14/RxD2, P16/TI01, and P17/TI02. All channels operate across the full 1.6–5.5 V supply range and support LIN 2.x frame formatting, break detection, and sync field handling required for automotive body electronics.
What is the maximum ADC resolution and channel count on the R5F104LDGFA#50?
The R5F104LDGFA#50 integrates a 10-bit successive-approximation ADC with up to 20 analog input channels. It supports both VDD-referenced and internal 1.45 V reference modes, includes an on-chip temperature sensor, and allows simultaneous sampling of multiple channels via hardware triggering. Conversion time is 1.6 μs per sample at 10-bit resolution, enabling high-speed sensor acquisition in motor control and industrial monitoring applications.
Is the R5F104LDGFA#50 pin-compatible with other RL78/G14 64-pin variants?
Yes, the R5F104LDGFA#50 shares identical pinout and package (64-pin LFQFP, 0.5 mm pitch) with all other RL78/G14 devices in the same pin-count family, including R5F104LGFA#50 and R5F104LEFA#50. This allows direct PCB reuse across memory variants, simplifying design scalability and inventory management. Peripheral pin assignments-including UART, ADC, and timer functions-are consistent across these variants per the RL78/G14 pin configuration diagrams.
