Product details
Overview
R5F104GFGFB#10 from Renesas is a 48-pin LFQFP, 96 KB flash, 12 KB RAM RL78/G14 16-bit microcontroller operating from 1.6–5.5 V, delivering 44 DMIPS at 32 MHz with ultra-low-power HALT/STOP/SNOOZE modes (66 μA/MHz active, 0.60 μA RTC+LVD), used in industrial sensor nodes and battery-powered HMI control units.
For engineers reviewing the R5F104GFGFB#10 datasheet, R5F104GFGFB#10 pinout, R5F104GFGFB#10 application, or R5F104GFGFB#10 equivalent, key selection criteria include its -40°C to +105°C industrial-grade temperature range (G-suffix), 48-pin 0.5 mm pitch LFQFP package, integrated 10-bit 20-channel ADC, dual UART/LIN support, and hardware DTC/ELC for deterministic peripheral event handling.
Technical Context
The R5F104GFGFB#10 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting instruction execution times from 0.03125 µs (32 MHz high-speed on-chip oscillator) to 30.5 µs (32.768 kHz subsystem clock), and includes multiply/divide/accumulate instructions with 1 MB address space.
It integrates a 10-bit A/D converter with 20 analog inputs, internal 1.45 V reference and temperature sensor; an 8-bit D/A converter with up to two outputs; two comparators; and a real-time clock with calendar, alarm, and clock correction-enabling autonomous timing-critical functions without external components.

FAQ
What is the maximum operating frequency and corresponding DMIPS rating for the R5F104GFGFB#10?
The R5F104GFGFB#10 operates at up to 32 MHz with a measured performance of 44 DMIPS. This rating is achieved using the high-speed on-chip oscillator and reflects integer instruction throughput under standard benchmark conditions defined by Renesas. The R5F104GFGFB#10 maintains this performance across its full 1.6–5.5 V supply range and -40°C to +105°C temperature envelope.
Does the R5F104GFGFB#10 support background operation during data flash rewriting?
Yes, the R5F104GFGFB#10 supports Background Operation (BGO) for its 4 KB data flash memory. This allows the CPU to execute code from program memory while data flash is being rewritten, eliminating execution stalls. The R5F104GFGFB#10 guarantees 1,000,000 rewrite cycles at VDD = 1.8–5.5 V, with no special voltage sequencing required.
What are the key low-power modes available on the R5F104GFGFB#10 and their typical current consumption?
The R5F104GFGFB#10 offers HALT, STOP, and SNOOZE modes. HALT halts the CPU while peripherals remain active (current depends on enabled modules). STOP disables all clocks except RTC/LVD (0.60 μA typical). SNOOZE enables selective peripheral operation during low-power wait states. All modes retain RAM content and support wake-up via interrupts or reset. The R5F104GFGFB#10 achieves 66 μA/MHz in active mode.
How many analog input channels does the integrated ADC support on the R5F104GFGFB#10?
The R5F104GFGFB#10 integrates a 10-bit successive-approximation ADC with up to 20 configurable analog input channels. It includes an internal 1.45 V reference voltage and an on-chip temperature sensor, enabling direct thermal monitoring without external components. Input voltage range is 0 to VDD, and conversions can be triggered by software, timer, or peripheral events via ELC.
Is the R5F104GFGFB#10 pin-compatible with other RL78/G14 variants in the same 48-pin LFQFP package?
Yes, all RL78/G14 devices in the 48-pin LFQFP package-including R5F104GFGFB#10, R5F104GGGFB#10, and R5F104GHGFB#10-share identical pinouts, electrical characteristics, and mechanical dimensions. This enables direct PCB footprint reuse across flash/RAM variants, simplifying design scalability and inventory management for the R5F104GFGFB#10 and its higher-memory counterparts.
