Product details
Overview
R5F104PLAFB#30 from Renesas is a 100-pin LFQFP (0.5 mm pitch), industrial-grade RL78/G14 16-bit microcontroller with 384 KB flash, 32 KB RAM, and 8 KB data flash, operating from 1.6–5.5 V at -40 to +105°C. It delivers 44 DMIPS at 32 MHz, features ultra-low power consumption (66 μA/MHz active, 0.60 μA RTC+LVD), and integrates UART, I²C, SPI, 12-bit RTC, 10-bit ADC (20 ch), and DTC/ELC peripherals for embedded control.
For engineers reviewing the R5F104PLAFB#30 datasheet, R5F104PLAFB#30 pinout, R5F104PLAFB#30 application, or R5F104PLAFB#30 equivalent, key selection criteria include its G-grade temperature rating, LFQFP-100 0.5 mm pitch package, integrated real-time clock with calendar/alarm, background data flash rewriting capability, and support for SNOOZE mode for low-power sensor wake-up.
Technical Context
The R5F104PLAFB#30 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 uses on-chip high-accuracy oscillator (±1.0% over -20 to +85°C) and supports HALT/STOP/SNOOZE low-power modes with dedicated LVD and POR circuits.
Peripheral integration includes Event Link Controller (ELC) for hardware-triggered peripheral chaining, Data Transfer Controller (DTC) with block/repeat/chain transfer, and dual-voltage interface I/O supporting 1.8/2.5/3.0 V logic levels - enabling direct interfacing with mixed-voltage sensors and communication ICs without level shifters.

The R5F104PLAFB#30 operates at a maximum frequency of 32 MHz and delivers 44 DMIPS performance. This benchmark reflects integer execution throughput under typical compiler-optimized code and is validated per Renesas' RL78/G14 documentation. The R5F104PLAFB#30 achieves this using its 3-stage pipeline RL78 CPU core with high-speed on-chip oscillator support.
Does the R5F104PLAFB#30 support background data flash rewriting (BGO), and what is the endurance specification?
Yes, the R5F104PLAFB#30 supports background data flash rewriting (BGO), allowing program execution from code flash while simultaneously rewriting data flash memory. Its data flash endurance is rated at 1,000,000 write/erase cycles (typical) with operation supported across the full VDD range of 1.8–5.5 V - enabling robust parameter storage in R5F104PLAFB#30-based field-deployed equipment.
What package type and pin count does the R5F104PLAFB#30 use, and is thermal pad connection required?
The R5F104PLAFB#30 uses a 100-pin LFQFP package with 14 × 14 mm body and 0.5 mm pitch. It includes an exposed thermal pad on the underside, which Renesas recommends connecting directly to VSS for optimal thermal performance and electrical stability. This requirement is documented in the RL78/G14 hardware user's manual for all LFQFP variants including the R5F104PLAFB#30.
What is the operating temperature range and qualification grade for the R5F104PLAFB#30?
The R5F104PLAFB#30 is qualified for industrial applications with an operating ambient temperature range of -40 to +105°C, designated as "G-grade" per Renesas' ordering nomenclature. This rating is confirmed in the RL78/G14 datasheet (R01DS0053EJ0370) and applies specifically to the R5F104PLAFB#30 variant, ensuring reliability in demanding environments such as motor drives and outdoor metering.
How many analog input channels and what ADC resolution does the R5F104PLAFB#30 provide?
The R5F104PLAFB#30 integrates a 10-bit successive-approximation ADC with up to 20 analog input channels (ANI0–ANI19), supporting differential and single-ended modes. It includes an internal 1.45 V reference voltage and on-die temperature sensor - all confirmed in the RL78/G14 datasheet section "A/D Converter". This ADC capability is fully implemented in the R5F104PLAFB#30 as part of its 384 KB flash, 32 KB RAM configuration.
