Product details
Overview
R5F104GJANA#U0 from Renesas is a 48-pin HWQFN-packaged RL78/G14 16-bit microcontroller with 192 KB flash, 20 KB RAM, and 8 KB data flash, operating at 1.6–5.5 V and supporting -40°C to +105°C industrial temperature range (G-grade). It integrates a 32 MHz RL78 CPU core delivering 44 DMIPS, ultra-low-power HALT/STOP/SNOOZE modes (66 μA/MHz active, 0.60 μA RTC+LVD), and peripherals including 12-channel 10-bit ADC, dual DAC, RTC, and UART/I²C/CSI interfaces for embedded control in battery-powered industrial sensors.
For engineers reviewing the R5F104GJANA#U0 datasheet, R5F104GJANA#U0 pinout, R5F104GJANA#U0 application, or R5F104GJANA#U0 equivalent, key selection criteria include its G-grade extended-temperature operation, HWQFN-48 (7×7 mm, 0.5 mm pitch) package with exposed die pad, integrated data flash rewrite capability (1M cycles), and support for background operation during flash programming - critical for firmware-over-the-air updates and real-time logging in field-deployed equipment.
Technical Context
The R5F104GJANA#U0 implements the RL78 CPU core with CISC architecture and 3-stage pipeline, enabling configurable instruction execution times from 0.03125 μs (32 MHz high-speed mode) to 30.5 μs (32.768 kHz ultra-low-power mode). Its memory subsystem includes 192 KB on-chip code flash (1 KB block size), 8 KB data flash with background operation (BGO), and 20 KB RAM - all accessible across the full 1 MB address space.
Peripheral integration centers on low-power system control: the Event Link Controller (ELC) enables hardware-triggered peripheral chaining without CPU intervention; the Data Transfer Controller (DTC) supports block/repeat transfers activated by 19–26 event sources; and the 12-bit interval timer, RTC (calendar/alarm/correction), and watchdog timer operate independently using dedicated clock domains - ensuring deterministic timing in safety-critical monitoring functions.

FAQ
What is the maximum operating frequency and corresponding DMIPS rating of the R5F104GJANA#U0?
The R5F104GJANA#U0 operates at up to 32 MHz with its RL78 CPU core, achieving 44 DMIPS performance. This benchmark reflects integer instruction throughput under standard conditions and is validated in Renesas' official documentation. The core supports dynamic clock scaling - including sub-MHz modes for ultra-low-power RTC operation - without compromising architectural compatibility or interrupt latency guarantees.
Does the R5F104GJANA#U0 support in-system programming and secure firmware updates?
Yes, the R5F104GJANA#U0 supports full in-system programming via its on-chip debug interface and includes multiple security features for firmware updates: flash shield window restricts write access to designated memory regions, block erase/write prohibition prevents unauthorized modification of protected code sections, and background operation (BGO) allows concurrent program execution and data flash rewriting - enabling secure, non-interrupting OTA updates in fielded devices.
What are the analog capabilities of the R5F104GJANA#U0, particularly regarding ADC and DAC resolution and channel count?
The R5F104GJANA#U0 integrates a 10-bit successive-approximation ADC with up to 20 input channels, internal 1.45 V reference voltage, and on-chip temperature sensor. It also includes two independent 8-bit voltage-mode DACs with 0 V to VDD output range and real-time update capability. These analog resources are fully operational across the device's 1.6–5.5 V supply range and support simultaneous sampling and conversion in multi-channel configurations.
How does the R5F104GJANA#U0 manage power consumption in low-power modes, and what peripherals remain active in STOP mode?
In STOP mode, the R5F104GJANA#U0 draws only 0.60 μA while maintaining operation of the real-time clock (RTC) with calendar/alarm functions and the low-voltage detector (LVD) with interrupt/reset capability. All other clocks and peripherals are halted. Wake-up is supported via RTC alarm, LVD threshold crossing, or external interrupts on designated pins - enabling precise, event-driven resumption of full operation with minimal energy overhead.
What package type and pin count does the R5F104GJANA#U0 use, and are there thermal design considerations?
The R5F104GJANA#U0 uses a 48-pin HWQFN package (7 mm × 7 mm, 0.5 mm pitch) with an exposed die pad. Renesas recommends connecting this pad directly to the VSS plane using multiple thermal vias to ensure effective heat dissipation and stable electrical reference. The #U0 suffix indicates tray packaging, and the device is rated for industrial G-grade operation (-40°C to +105°C), requiring PCB layout adherence to Renesas' thermal and decoupling guidelines - especially for the REGC capacitor (0.47–1 μF to VSS).
