Product details
Overview
R5F104LHGFP#30 from Renesas is a 64-pin LFQFP, 512 KB flash, 8 KB data flash, 20 KB RAM RL78/G14 16-bit microcontroller operating from 1.6–5.5 V, delivering 44 DMIPS at 32 MHz with ultra-low power consumption (66 μA/MHz active, 0.60 μA RTC+LVD mode), used in industrial sensor nodes and battery-powered control modules.
For engineers reviewing the R5F104LHGFP#30 datasheet, R5F104LHGFP#30 pinout, R5F104LHGFP#30 application, or R5F104LHGFP#30 equivalent, key selection considerations include its 64-pin LFQFP-0.5 mm package, integrated RTC with calendar/alarm, 12-bit interval timer, dual UART/LIN support, and 16-channel 10-bit ADC with internal temperature sensor and 1.45 V reference.
Technical Context
The R5F104LHGFP#30 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting instruction execution times from 0.03125 µs (32 MHz high-speed on-chip oscillator) to 30.5 µs (32.768 kHz subsystem clock). It integrates Event Link Controller (ELC) for hardware-triggered peripheral chaining and Data Transfer Controller (DTC) with block/chain transfer modes activated by interrupt sources.
It features dual serial interface sets: three UART/LIN channels (one with LIN bus support), up to ten I²C/simplified I²C channels, and up to eight CSI (SPI-compatible) channels. The analog subsystem includes an 8/10-bit ADC with 16–20 input channels, two 8-bit DAC outputs, and two comparator channels with selectable internal/external reference voltage.

IC Role / Device Role / Timing Role: Main controller managing sensor acquisition (ADC/DAC/comparator), RTC-based sampling schedule, and low-power sleep/wake cycles. Use Value: 0.60 μA STOP mode extends 2xAA battery life beyond 5 years; integrated 1.45 V reference and temp sensor reduce BOM count by two components. | Use Scenario: Motorized damper control module receiving commands over LIN bus and regulating position via PWM-driven actuator. IC Role / Device Role / Timing Role: LIN slave node executing closed-loop position control using Timer RD for PWM generation and ELC-triggered ADC feedback sampling.

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F104LJGFP#30 | Same 64-pin LFQFP package, 192 KB flash, 8 KB data flash, 20 KB RAM - reduced code density but identical peripheral set and pinout | Suitable where firmware size < 192 KB; lower cost for legacy or less feature-rich designs | Select when full 512 KB flash is unnecessary and BOM cost optimization is prioritized over future firmware headroom |
| R5F104LLGFP#30 | Same 64-pin LFQFP package, 384 KB flash, 8 KB data flash, 32 KB RAM - intermediate memory tier with larger SRAM for complex buffers or stacks | Better suited for applications requiring larger protocol stacks (e.g., MQTT over TLS) or real-time FFT-based analytics | Choose when >20 KB RAM is needed for multi-threaded FreeRTOS tasks or large communication buffers without external RAM |

FAQ
What is the maximum operating frequency and associated performance of the R5F104LHGFP#30?
The R5F104LHGFP#30 operates up to 32 MHz using its high-accuracy on-chip oscillator (±1.0% over −40°C to +105°C), delivering 44 DMIPS. Its 3-stage pipeline RL78 core supports minimum instruction execution times from 0.03125 µs (32 MHz) down to 30.5 µs (32.768 kHz), enabling dynamic clock scaling for power/performance trade-offs in the R5F104LHGFP#30.
Does the R5F104LHGFP#30 support LIN bus communication, and which peripheral implements it?
Yes, the R5F104LHGFP#30 supports LIN bus communication via UART2 - one of its three UART channels explicitly qualified for LIN 2.2A/ISO 17987-4 compliance. This channel includes break-detection, sync-field processing, and checksum calculation hardware, enabling direct connection to a LIN transceiver without external protocol assist, as confirmed in the R5F104LHGFP#30 datasheet Section 1.1.
What are the data flash endurance and voltage requirements for rewriting the R5F104LHGFP#30?
The R5F104LHGFP#30 features 8 KB of data flash rated for 1,000,000 write/erase cycles (typical) with operation supported across the full VDD range of 1.8–5.5 V. Rewrites can occur in background (BGO mode) while code executes from main flash, and the flash library reserves fixed RAM regions (e.g., F3F00H start address for R5F104xL variants) - all verified in the R5F104LHGFP#30's Flash Self-Programming Library documentation.
How does the Event Link Controller (ELC) enhance real-time response in the R5F104LHGFP#30?
The ELC in the R5F104LHGFP#30 enables hardware-level linking of 19–26 peripheral events (e.g., timer overflow → ADC start → DTC transfer → interrupt), eliminating CPU intervention and reducing latency to sub-microsecond levels. This allows deterministic, jitter-free signal chains - such as synchronized ADC sampling triggered by PWM edges - without software overhead, a capability confirmed in the R5F104LHGFP#30's ELC functional description.
What is the analog input channel count and reference configuration for the ADC in the R5F104LHGFP#30?
The R5F104LHGFP#30 integrates a 10-bit successive-approximation ADC with up to 20 analog input channels (ANI0–ANI19), supporting both internal 1.45 V reference and external reference inputs. It includes an on-chip temperature sensor and AVREFP/AVREFM differential reference pins, allowing ratiometric or absolute measurements - specifications directly listed in the R5F104LHGFP#30's "A/D Converter" feature table.
