Product details
Overview
R5F104GAAFB#30 from Renesas is a 48-pin LFQFP, 0.5 mm pitch, industrial-grade (−40°C to +105°C) RL78/G14 16-bit MCU with 128 KB code flash, 8 KB data flash, and 12 KB RAM. It delivers 44 DMIPS at 32 MHz, operates from 1.6 V to 5.5 V, and supports ultra-low-power modes including STOP (0.60 μA) and HALT (66 μA/MHz), targeting battery-powered sensor nodes and motor control interfaces.
For engineers reviewing the R5F104GAAFB#30 datasheet, R5F104GAAFB#30 pinout, R5F104GAAFB#30 application, or R5F104GAAFB#30 equivalent, this page provides verified electrical specifications, validated pin functions, confirmed industrial-temperature operation, and real-world use cases in embedded control systems requiring secure firmware updates and mixed-signal integration.
Technical Context
The R5F104GAAFB#30 implements the RL78 CPU core with CISC architecture, 3-stage pipeline, and configurable instruction timing (0.03125 µs minimum at 32 MHz). It integrates a 12-bit A/D converter with up to 20 channels, dual D/A outputs, two comparators, and a calendar-capable real-time clock with alarm and correction functions.
Peripheral subsystems include 3–4 UART/LIN channels, 4–10 I²C interfaces, 3–8 CSI (SPI-compatible) channels, and multiple timer units (TAU, RJ, RD, RG) supporting PWM generation, input capture, and event-triggered DMA via the Data Transfer Controller (DTC) and Event Link Controller (ELC).

This frequency is achievable across the full −40°C to +105°C industrial temperature range with VDD = 1.6 V to 5.5 V, and supports dynamic clock switching to lower frequencies for power optimization.
Does the R5F104GAAFB#30 support in-circuit debugging?
Yes, the R5F104GAAFB#30 includes an on-chip debug interface compliant with Renesas E1/E20 emulators. It supports full breakpoint control, real-time variable watch, and flash programming via the dedicated TOOL0/TOOLRxD/TOOLTxD pins - no external JTAG adapter required for development.
What is the data flash endurance specification for the R5F104GAAFB#30?
The R5F104GAAFB#30 specifies 1,000,000 write/erase cycles (typical) for its 8 KB data flash memory. This endurance applies across the full operating voltage range (VDD = 1.8 V to 5.5 V) and supports background operation (BGO), enabling concurrent program execution and data logging without CPU suspension.
Can the R5F104GAAFB#30 operate from a 1.8 V supply?
Yes, the R5F104GAAFB#30 supports 1.6 V to 5.5 V operation, making it fully functional at 1.8 V. At this voltage, it maintains full peripheral operation including ADC, UART, and timers, and achieves ultra-low-power STOP mode current of 0.60 μA - ideal for coin-cell or energy-harvesting systems.
How many I²C interfaces does the R5F104GAAFB#30 provide?
The R5F104GAAFB#30 provides four I²C interfaces (SCLA0/SDAA0, SCLA1/SDAA1, SCLA2/SDAA2, SCLA3/SDAA3), each supporting standard-mode (100 kHz) and fast-mode (400 kHz) operation. Pins are multiplexed with other functions (e.g., P60/P61 for SCLA0/SDAA0), and all channels support multi-master arbitration and 7-bit/10-bit addressing.
