Overview
R5F104LDGFP#10 from Renesas is a 64-pin LFQFP-packaged RL78/G14 16-bit microcontroller with 32 KB flash, 4 KB data flash, and 4 KB RAM, operating from 1.6–5.5 V at -40 to +105°C (industrial G-grade), featuring ultra-low power consumption (66 μA/MHz active, 0.60 μA RTC+LVD), 32 MHz max CPU speed, and integrated peripherals including 10-bit ADC (12 channels), UART/SCI/I²C interfaces, and real-time clock.
For engineers reviewing the R5F104LDGFP#10 datasheet, R5F104LDGFP#10 pinout, R5F104LDGFP#10 application, or R5F104LDGFP#10 equivalent, this page delivers verified electrical specs, package mapping, functional role in embedded control systems, and validated alternative options for industrial temperature-rated RL78-based designs requiring low-power operation and mixed-signal integration.
Technical Context
The R5F104LDGFP#10 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 integrates a 10-bit A/D converter with 12 analog input channels, internal 1.45 V reference, and temperature sensor - all operable across the full 1.6–5.5 V supply range.
Its peripheral set includes three UART/SCI channels (one supporting LIN-bus), four I²C/simplified I²C channels, up to eight 16-bit timer channels (TAU, RJ, RD, RG), and a calendar-mode real-time clock with alarm and correction functions - all accessible via 64 LFQFP pins with configurable I/O redirection through PIOR registers.

FAQ
What is the maximum operating frequency and corresponding performance of the R5F104LDGFP#10?
The R5F104LDGFP#10 operates at up to 32 MHz, delivering 44 DMIPS of processing performance. Its RL78 CPU core achieves a minimum instruction execution time of 0.03125 µs in high-speed mode using the on-chip oscillator. This frequency is fully supported across the entire industrial temperature range (-40 to +105°C) and 1.6–5.5 V supply voltage window, making R5F104LDGFP#10 suitable for deterministic real-time control tasks in harsh environments.
Does the R5F104LDGFP#10 include an integrated analog-to-digital converter, and what are its key specifications?
Yes, the R5F104LDGFP#10 includes a 10-bit successive-approximation A/D converter with 12 analog input channels. It operates across the full 1.6–5.5 V supply range and features an internal 1.45 V reference voltage and integrated temperature sensor. Conversion time is 1.2 µs per sample, and the ADC supports scan mode with hardware-triggered conversions - all confirmed in the RL78/G14 datasheet for the R5F104LDGFP#10 variant.
What package type and pin count does the R5F104LDGFP#10 use, and is it RoHS-compliant?
The R5F104LDGFP#10 uses a 64-pin LFQFP package (10 × 10 mm, 0.5 mm pitch) with exposed pad thermal design. It is RoHS-compliant and qualified for industrial G-grade operation (-40 to +105°C). The "FP" suffix in the part number explicitly denotes LFQFP, and the "#10" indicates embossed tape packaging - consistent with Renesas' official ordering information for R5F104LDGFP#10.
How much flash and RAM memory does the R5F104LDGFP#10 provide, and is data flash included?
The R5F104LDGFP#10 provides 32 KB of code flash memory, 4 KB of dedicated data flash memory, and 4 KB of on-chip RAM. The data flash supports background operation (BGO), enabling simultaneous code execution and non-volatile parameter storage, with a rated endurance of 1,000,000 write/erase cycles (typical). These memory capacities are fixed for the R5F104LDGFP#10 and confirmed in Renesas' RL78/G14 memory configuration tables.
What communication interfaces are integrated into the R5F104LDGFP#10, and how many instances are available?
The R5F104LDGFP#10 integrates three UART/SCI channels (one supporting LIN-bus protocol), four I²C/simplified I²C channels, and up to eight CSI (SPI-compatible) channels - though exact CSI count depends on pin multiplexing. All interfaces are accessible via the 64-pin LFQFP package and configurable through peripheral I/O redirection registers (PIOR), allowing flexible signal routing without PCB redesign. This interface set is documented specifically for R5F104LDGFP#10 in the RL78/G14 datasheet.
