Product details
Overview
R5F100GJGNA#W0 from Renesas is a 48-pin HWQFN-packaged RL78/G13 16-bit microcontroller with 128 KB flash, 8 KB data flash, and 12 KB RAM, operating from 1.6 V to 5.5 V at up to 32 MHz (41 DMIPS), featuring ultra-low-power modes (0.57 μA RTC+LVD), 10-bit ADC (26 channels), and integrated real-time clock - deployed in battery-powered industrial sensors and smart metering endpoints.
For engineers reviewing the R5F100GJGNA#W0 datasheet, R5F100GJGNA#W0 pinout, R5F100GJGNA#W0 application, or R5F100GJGNA#W0 equivalent, key selection criteria include its 48-pin HWQFN-0.5mm package, -40°C to +105°C industrial temperature grade (G-suffix), on-chip debug support, and background data flash rewriting capability for firmware updates without halting operation.
Technical Context
The R5F100GJGNA#W0 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 subsystem clock). It integrates dual-clock domains: high-speed on-chip oscillator (±1.0% accuracy, 1–32 MHz selectable) and dedicated low-speed oscillator for watchdog and RTC.
Its peripheral set includes 8× 16-bit timers, 1× 12-bit interval timer, 1× calendar RTC with alarm/correction, 2–4 channel DMA, UART/LIN, I²C, CSI, 10-bit ADC with internal 1.45 V reference and temperature sensor, and hardware multiplier/divider/MAC - all optimized for deterministic real-time control in resource-constrained embedded systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core Architecture | RL78 16-bit CISC with 3-stage pipeline; enables deterministic interrupt latency and compact code footprint for cost-sensitive control applications. |
| Max Operating Frequency | 32 MHz (41 DMIPS); delivers sufficient throughput for motor control, sensor fusion, and protocol stack handling without external clock sources. |
| Flash Memory | 128 KB code flash + 8 KB data flash; supports self-programming with boot swap and flash shield window for secure firmware updates. |
| RAM | 12 KB on-chip RAM; accommodates real-time task stacks, communication buffers, and calibration data storage in standalone edge nodes. |
| Power Consumption | 66 μA/MHz active; 0.57 μA in STOP mode with RTC + LVD active; enables multi-year battery life in wireless sensor transmitters. |
| Analog Peripherals | 10-bit ADC with 26 input channels, internal 1.45 V reference, and integrated temperature sensor; eliminates need for external references in environmental monitoring. |

Pinout & Package
Package: 48-pin HWQFN (7 mm × 7 mm, 0.5 mm pitch), moisture sensitivity level (MSL) 3, RoHS-compliant, thermal pad exposed on bottom for enhanced heat dissipation in sealed enclosures.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD, VSS | Power supply and ground | Dual VDD pins (Pins 1, 48) and multiple VSS (Pins 2, 24, 25, 47) ensure stable core/peripheral rail decoupling and low-noise analog operation. |
| P00–P07, P10–P17, P20–P27, P30–P37, P40–P47 | General-purpose I/O ports | 48 total I/O pins with N-ch open-drain capability (6 V tolerant), TTL input buffer, and programmable pull-up resistors - supports mixed-voltage interfacing (1.8/2.5/3.3 V). |

Key Features
| Feature | Design Value |
|---|---|
| SNOOZE mode with UART auto-wakeup | Permits low-power listening for serial commands while consuming <1.5 μA - ideal for always-on command interfaces in HVAC controllers. |
| Background Data Flash Operation (BGO) | Enables concurrent program execution and data flash rewrite (1M cycles TYP.), allowing over-the-air firmware patching without system interruption. |
| On-chip RTC with calendar and correction | 99-year calendar, alarm, and ±1 ppm correction via 32.768 kHz crystal - eliminates external RTC IC in time-stamped logging applications. |
| Hardware multiplier/divider/MAC | 16×16→32-bit multiply, 32÷32→32-bit divide, and MAC operations execute in fixed cycles - accelerates PID loop math and sensor linearization. |
| Key interrupt and buzzer output controller | Dedicated hardware detects key press/release and drives piezo buzzers directly - reduces GPIO and timer overhead in HMI subsystems. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F101GJGNA#W0 | No data flash memory (0 KB); identical core, peripherals, and package. | Not suitable for applications requiring nonvolatile parameter storage or firmware updates in field; requires external EEPROM or FRAM. | Select when data retention needs are met externally and BOM cost reduction is prioritized over in-field update capability. |
| RA2A1EKB20FBC0#AC0 | Arm Cortex-M23 core, 128 KB flash, 32 KB SRAM, 24-channel 12-bit ADC, operates up to 48 MHz. | Better computational throughput and larger RAM for complex connectivity stacks (USB, CAN FD), but higher active power (120 μA/MHz). | Choose for next-generation designs needing Arm ecosystem compatibility, TLS offload, or future-proofing beyond RL78 toolchain constraints. |
Compared with R5F100GJGNA#W0, R5F101GJGNA#W0 removes data flash to reduce cost and die size while retaining identical control capabilities, whereas RA2A1EKB20FBC0 offers higher performance and modern architecture at the expense of increased power and software migration effort.

Does the R5F100GJGNA#W0 include an integrated temperature sensor, and how is it accessed?
Yes, the R5F100GJGNA#W0 includes an on-chip temperature sensor accessible via ANI25 (P27) when configured in HS (high-speed main) mode. Its output is digitized by the 10-bit ADC and calibrated to deliver ±3°C accuracy across the -40°C to +105°C range, as specified in the RL78/G13 datasheet Section 1.1 "A/D converter".
What packaging and moisture sensitivity level (MSL) apply to the R5F100GJGNA#W0?
The R5F100GJGNA#W0 uses a 48-pin HWQFN package (7 mm × 7 mm, 0.5 mm pitch) with an exposed thermal pad, rated MSL Level 3 per J-STD-020. It ships in embossed tape (#W0 suffix) and requires bake conditioning if exposed to ambient >30°C/60% RH for more than 168 hours before reflow.
How does the data flash memory in the R5F100GJGNA#W0 support firmware updates in the field?
The R5F100GJGNA#W0's 8 KB data flash supports Background Operation (BGO), enabling code execution from main flash while rewriting data flash sectors. With 1,000,000 write cycles (TYP.) and VDD = 1.8–5.5 V operation, it facilitates secure, atomic firmware patching without system reset - critical for remote industrial devices.
Is the R5F100GJGNA#W0 qualified for automotive applications, and what temperature grade does it carry?
The R5F100GJGNA#W0 carries the 'G' suffix, indicating qualification for industrial applications over -40°C to +105°C ambient temperature.
