Product details
Overview
R5F104LGAXXXFB#V0 from Renesas is a 64-pin LFQFP, 0.5 mm pitch, industrial-grade (G) RL78/G14 16-bit MCU with 512 KB flash, 48 KB RAM, 8 KB data flash, and operation up to +105°C. It delivers 44 DMIPS at 32 MHz, consumes 66 μA/MHz active and 0.60 μA in RTC+LVD mode, and integrates UART, I²C, SPI, 16-bit timers, 10-bit ADC (20 ch), and real-time clock.
For engineers reviewing the R5F104LGAXXXFB#V0 datasheet, R5F104LGAXXXFB#V0 pinout, R5F104LGAXXXFB#V0 application, or R5F104LGAXXXFB#V0 equivalent, key selection criteria include its 64-pin LFQFP-0.5mm package, -40 to +105°C industrial temperature rating, integrated data flash with 1M rewrite cycles, low-power HALT/STOP/SNOOZE modes, and peripheral flexibility via ELC and DTC.
Technical Context
The R5F104LGAXXXFB#V0 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 supports multiply/divide/accumulate instructions and features a 1 MB address space with four banks of 8-bit general-purpose registers.
Its power management includes on-chip POR, 14-level LVD with interrupt/reset options, and ultra-low-power modes enabled by dedicated oscillators - including a high-accuracy ±1.0% on-chip oscillator (1–64 MHz) and separate low-speed oscillator for watchdog operation.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F104LLAFB#V0 | Same 64-pin LFQFP-0.5mm package, identical 512 KB flash/48 KB RAM, but rated for -40 to +85°C (D grade) | Not qualified for +105°C environments; suitable for commercial/industrial indoor use only | Select when ambient temperature stays below +85°C and cost optimization is prioritized over extended thermal range |
| R5F104LKAFB#V0 | Same package and temperature grade, but with 384 KB flash and 32 KB RAM - reduced memory footprint | Lower memory capacity limits firmware complexity; insufficient for full OTA stack + dual-bank updates | Choose when application firmware fits within 384 KB and BOM cost reduction outweighs headroom for future feature expansion |

FAQ
What is the operating temperature range specified for the R5F104LGAXXXFB#V0?
The R5F104LGAXXXFB#V0 is rated for industrial operation from -40°C to +105°C (G grade), validated per Renesas' qualification standards for extended thermal environments. This makes the R5F104LGAXXXFB#V0 suitable for under-hood automotive modules, factory-floor controllers, and outdoor metering equipment where ambient heat exceeds +85°C.
Does the R5F104LGAXXXFB#V0 include on-chip debug capability?
Yes, the R5F104LGAXXXFB#V0 integrates full on-chip debug functionality with flash shield window protection. This allows secure in-system programming and real-time debugging via the on-chip debug interface without exposing full flash contents - a requirement for certified industrial firmware development. The R5F104LGAXXXFB#V0 supports standard Renesas E2 emulator and CS+ IDE workflows.
How many I²C interfaces does the R5F104LGAXXXFB#V0 support?
The R5F104LGAXXXFB#V0 supports up to 10 I²C/simplified I²C channels, with P60/SCLA0 and P61/SDAA0 assigned as one dedicated hardware I²C interface. Additional channels are implemented via software bit-banging or peripheral function remapping using the PIOR registers - enabling concurrent communication with multiple sensors, EEPROMs, or PMICs without external bus expanders.
What is the data flash endurance and voltage range for programming the R5F104LGAXXXFB#V0?
The R5F104LGAXXXFB#V0 includes 8 KB of data flash rated for 1,000,000 write/erase cycles (typical) and programmable across the full VDD range of 1.8 V to 5.5 V. Background operation (BGO) allows CPU execution from code flash while rewriting data flash - essential for logging, calibration storage, or OTA update staging in the R5F104LGAXXXFB#V0.
Is the R5F104LGAXXXFB#V0 pin-compatible with other RL78/G14 variants in the same package?
Yes, all RL78/G14 devices in the 64-pin LFQFP-0.5mm package (e.g., R5F104LKAFB#V0, R5F104LLAFB#V0, R5F104LGAXXXFB#V0) share identical pinouts and electrical characteristics. This enables direct substitution within the same footprint for memory or temperature grade upgrades - provided firmware is recompiled to match the target device's memory map and feature set.
