Product details
Overview
R5F104MJAFB#30 from Renesas is a 80-pin LFQFP, 0.5 mm pitch, industrial-grade (TA = −40 to +105°C) RL78/G14 16-bit MCU with 192 KB flash, 8 KB data flash, 20 KB RAM, 32 MHz max CPU speed (44 DMIPS), and ultra-low-power operation (66 μA/MHz active, 0.60 μA RTC+LVD mode). It integrates UART, I²C, SPI, 12-bit RTC, 10-bit ADC (16 ch), 8-bit DAC (2 ch), and programmable gain amplifier - deployed in motor control, sensor hubs, and industrial HMI.
For engineers reviewing the R5F104MJAFB#30 datasheet, R5F104MJAFB#30 pinout, R5F104MJAFB#30 application, or R5F104MJAFB#30 equivalent, key selection criteria include its 80-pin LFQFP-0.5 mm package, 192 KB/8 KB/20 KB memory configuration, −40°C to +105°C industrial temperature grade, integrated event link controller (ELC), and background data flash rewriting capability.
Technical Context
The R5F104MJAFB#30 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), plus multiply/divide/accumulate instructions and 1 MB address space. It features dual-clock domains: high-speed on-chip oscillator (selectable 1–64 MHz, ±1.0% accuracy) and subsystem clock for RTC/LVD.
Peripheral integration includes Event Link Controller (ELC) enabling hardware-triggered peripheral chaining without CPU intervention, Data Transfer Controller (DTC) supporting block/repeat/normal transfer modes activated by 19–26 event sources, and Real-time Clock with calendar (99-year), alarm, and clock correction functions - all operating in STOP/HALT/SNOOZE low-power modes.

The R5F104MJAFB#30 operates at up to 32 MHz using its high-speed on-chip oscillator, delivering 44 DMIPS performance. Its RL78 CPU core achieves this with a 3-stage pipeline and supports configurable instruction timing - from 0.03125 µs (32 MHz) to 30.5 µs (32.768 kHz) - enabling deterministic real-time response across power modes.
Does the R5F104MJAFB#30 support background data flash rewriting (BGO), and what is the endurance specification?
Yes, the R5F104MJAFB#30 supports background data flash rewriting (BGO), allowing CPU code execution from program memory while data flash is being rewritten. The data flash endurance is rated at 1,000,000 write/erase cycles (typical), with operation supported across the full VDD range of 1.8 V to 5.5 V - essential for reliable firmware parameter storage.
What are the temperature grade and packaging details for the R5F104MJAFB#30?
The R5F104MJAFB#30 is qualified for industrial operation from −40°C to +105°C (G-grade) and housed in an 80-pin LFQFP package with 12 × 12 mm body size and 0.5 mm pin pitch. The package includes an exposed thermal pad recommended to be connected to VSS for optimal thermal dissipation in high-duty-cycle applications.
How many analog input channels does the R5F104MJAFB#30 support, and what ADC resolution and reference options are available?
The R5F104MJAFB#30 integrates a 10-bit successive approximation register (SAR) ADC supporting up to 16 analog input channels. It provides an internal 1.45 V reference voltage and supports external reference inputs. Temperature sensor and AVREFP/AVREFM differential references are also available - enabling accurate sensor measurements across voltage and temperature variations.
Is the R5F104MJAFB#30 pin-compatible with other RL78/G14 variants in the same 80-pin LFQFP package?
Yes, the R5F104MJAFB#30 shares identical pinout and electrical characteristics with other RL78/G14 80-pin LFQFP variants (e.g., R5F104MHAFB#30, R5F104MGAFB#30), differing only in flash/RAM capacity and factory-programmed features. This enables scalable design reuse - for example, upgrading from 128 KB to 192 KB flash without PCB revision.
