Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F104GGGFB#50 | 128 KB flash, 12 KB RAM, same package - differs only in factory-programmed ROM content and minor mask revision | Identical functional scope and pin compatibility - suitable for drop-in replacement where firmware is reloaded | Select when sourcing requires latest mask version or specific Renesas wafer lot traceability |
| RL78/G13 R5F100LGJFP#30 | 48-pin LQFP, 128 KB flash, 8 KB RAM, -40°C to +85°C (D-grade) - lacks VCOUTx, fewer ADC channels (8 vs 16) | Consumer/industrial automation where extended temperature is not required and lower analog channel count suffices | Choose for cost-sensitive designs with relaxed temp range and reduced analog I/O needs |
Compared with R5F104GEGFB#50, R5F104GGGFB#50 offers identical electrical and thermal specs with updated mask ROM, while RL78/G13 R5F100LGJFP#30 trades industrial temperature and enhanced analog capability for lower cost and simpler qualification - making it viable only where G-grade operation and full ADC channel count are noncritical.

FAQ
What is the maximum operating frequency and associated performance of the R5F104GEGFB#50?
The R5F104GEGFB#50 operates at up to 32 MHz, delivering 44 DMIPS performance. Its RL78 CPU core achieves this with a 3-stage pipeline and supports minimum instruction execution times from 0.03125 µs (at 32 MHz with high-speed oscillator) down to 30.5 µs (at 32.768 kHz). This enables both high-throughput control loops and ultra-low-power real-time monitoring in the same device.
Does the R5F104GEGFB#50 support in-system programming and secure firmware updates?
Yes, the R5F104GEGFB#50 supports self-programming of code and data flash memory with boot swapping and flash shield window protection. It includes a security function that prohibits block erase and rewriting of protected flash regions. The on-chip debug function enables programming via the dedicated debug UART (P50/P51), and background operation (BGO) allows code execution during data flash writes - essential for field-upgradable firmware.
What analog peripherals are integrated into the R5F104GEGFB#50, and how are they configured?
The R5F104GEGFB#50 integrates a 10-bit ADC with 16 input channels (ANI0–ANI15), internal 1.45 V reference voltage, and on-chip temperature sensor. It also includes two 8-bit DACs (output voltage 0–VDD) and two comparators with window mode. Analog functions are assigned to pins P20–P27 and P120/P147 via fixed mappings and peripheral I/O redirection registers, enabling flexible sensor interface design without external components.
How does the R5F104GEGFB#50 manage power in battery-operated applications?
The R5F104GEGFB#50 achieves 66 μA/MHz active current and 0.60 μA in STOP mode (RTC + LVD only). It supports HALT, STOP, and SNOOZE low-power modes, programmable LVD with 14 voltage thresholds, and POR circuitry. These features allow rapid wake-up from deep sleep, precise brown-out detection, and extended runtime in applications like portable meters and wireless sensors - all without external power management ICs.
Is the R5F104GEGFB#50 pin-compatible with other RL78/G14 variants, and what package options exist?
Yes, the R5F104GEGFB#50 uses the 48-pin LFQFP (0.5 mm pitch) package and is pin-compatible with all other RL78/G14 48-pin variants, including R5F104GGGFB#50 and R5F104GHGFB#50. Other 48-pin options include HWQFN (R5F104GEANA#U0) and LQFP (R5F104GEAFP#V0), but LFQFP variants share identical pinout and electrical characteristics - simplifying migration and second-source strategies.
