R5F100LGAFB#10 概述
A microcontroller (MCU) is an integrated circuit containing a CPU, memory and programmable peripherals on a single die. The RL78 is a 16-bit CISC architecture from Renesas that bridges 8-bit legacy designs and 32-bit Cortex-M parts, optimized for low active current and standby consumption. Within Renesas' portfolio the RL78 family sits between 8-bit RL78/G10 and 32-bit RX/Renesas Synergy families. Because the R5F100LGAFB#10 is in the G13 sub-family it supports 1.6V-5.5V, multiple low-power modes, and on-chip data flash for EEPROM emulation.
Key features include on-chip oscillator, 10-bit A/D converter, 8-bit D/A converter output, hardware multiplier, DMA, comparator, timers and a safety subsystem that detects illegal hardware operation. The safety engine plus IEC/UL 60730 class-B support simplifies compliance for household appliances and white goods.
Architecturally the device uses a 3-stage pipelined 16-bit CPU with a Harvard-style Flash/SRAM bus. The high-speed on-chip oscillator (±1% accuracy) eliminates an external crystal in many designs, and data Flash lets users emulate EEPROM at byte granularity without external chips.
Typical applications include white goods, sensor nodes, battery-powered IoT nodes, smart meters, HVAC controls, and small home appliances. Its wide voltage range and low STOP current also suit energy-harvesting and remote-control products.
Designers should evaluate the 64-LFQFP package's thermal characteristics (about 50 C/W theta_JA) and keep analog traces short because the 10-bit ADC at 1.6V is sensitive to digital switching noise. The `#10` suffix denotes factory programming version; firmware reordering is recommended before mask-ROM migration.

典型应用
R5F100LGAFB#10 适用于 7 应用s: White Goods / Household Appliances, Battery-Powered IoT Sensor Nodes, Smart Meters (Electricity / Gas / Water), HVAC Climate Control, Consumer Remote Controls, Industrial Sensor Transmitters, Medical Health Monitoring.
White Goods / Household Appliances
The R5F100LGAFB#10 is a strong fit for white goods because of its IEC/UL 60730 class-B hardware safety support and 230 nA STOP standby current, which directly simplifies compliance for washing machines, dishwashers, induction cookers, and microwave ovens. The 128 KB code flash holds a full motor-control or HMI state machine plus user-interface logic, while the 10-bit ADC reads temperature and current sensors accurately across the 1.6-5.5 V supply range. Renesas provides certified self-test firmware, so designers typically omit a separate safety supervisor. Compared with a discrete 8-bit solution, the integrated DMA and 32 KB SRAM reduce BOM and PCB area significantly.
推荐
Battery-Powered IoT Sensor Nodes
In battery-powered IoT sensor nodes, the R5F100LGAFB#10's 230 nA STOP current and 66 µA/MHz active consumption extend CR2032 coin-cell lifetime to multiple years for periodic measurement duty cycles. The 1.6-5.5 V operating range accepts a single Li-ion, two AA cells, or energy-harvested power, eliminating boost converters in many designs. The on-chip 10-bit ADC plus comparator wake on analog thresholds lets the MCU sleep until an event fires, with 128 KB flash reserved for over-the-air update images. Its wide temperature range (-40 to +85 °C) handles outdoor enclosures without derating.
推荐
Smart Meters (Electricity / Gas / Water)
The R5F100LGAFB#10 suits smart electricity, gas, and water meters because the 128 KB flash stores metering firmware, calibration tables, and rolling consumption logs in data flash for EEPROM-free designs. Its 32 MHz CPU delivers 43.2 DMIPS, sufficient for real-time energy calculations and protocol stacks (DLMS/COSEM or wireless M-Bus) without an external host processor. The 1.6 V minimum supply lets it run directly from a single alkaline cell with a step-down regulator, and the low STOP current preserves battery life during outage reporting. Hardware IEC 60730 class-B support accelerates compliance certification.
推荐
HVAC Climate Control
HVAC indoor-unit controllers benefit from the R5F100LGAFB#10's mix of low power, 128 KB code flash, and a 10-bit ADC that reads NTC thermistors, humidity sensors, and airflow transducers with adequate resolution. The integrated timer array supports up to six PWM channels for fan motors and triac-fired compressor drivers without an external timer IC. STOP current at 230 nA lets the panel sit idle in eco mode drawing negligible standby power, while the RL78 core wakes fast enough to maintain comfort-loop latency below 100 ms. The 64-LFQFP gives enough I/O for keypad, LCD, and IR receiver inputs.
推荐
Consumer Remote Controls
The R5F100LGAFB#10 is ideal for universal remote controls because of its 230 nA STOP current, which lets the device sleep for years on a pair of AAA cells. The on-chip 10-bit ADC reads battery voltage and IR photodiode signals without external components. The hardware multiplier and DMA accelerate IR protocol decoding (RC5, NEC, Sony SIRC) and audio-baseband processing for voice-equipped remotes. The 64-LFQFP offers 58 GPIO for key-scan matrices, IR LED drivers, and LED-backlighting PWM channels, eliminating the need for an I/O expander.
推荐
Industrial Sensor Transmitters
Industrial 4-20 mA sensor transmitters and field-instrumentation nodes use the R5F100LGAFB#10 to combine sensor linearization, HART or IO-Link protocol handling, and diagnostics in one chip. The 128 KB flash holds sensor calibration curves and protocol stacks; the 32 KB SRAM buffers measurement frames for asynchronous transmission. Operating from -40 to +85 °C, the part tolerates plant-floor environments, and the 10-bit ADC provides enough resolution for pressure and flow measurements when paired with an external PGA. Low STOP current extends battery life in loop-powered 4-20 mA nodes.
推荐
Medical Health Monitoring
Low-end medical and personal-health monitors such as digital thermometers, pulse oximeters, and pill dispensers fit well with the R5F100LGAFB#10. The 32 MHz RL78 core runs 43.2 DMIPS, enough for SpO2 algorithms and display rendering without external DSP. The 10-bit ADC reads thermistor, photo-plethysmography (PPG), and weight-scale signals, while the 1.6-5.5 V range accepts single-cell Li-ion power directly. The on-chip data flash stores patient logs non-volatilely, eliminating an external EEPROM and reducing BOM. STOP current under 1 µA extends battery life between charges.

关键差异点
- Lowest active current in 16-bit MCU class （对比 R5F100LGAFB#70 (same silicon, different finish suffix))
- Integrated IEC 60730 class-B safety hardware （对比 R5F100FCAFP#10 (smaller-density G13 sibling))
- 128 KB Flash + 32 KB SRAM in 64-LFQFP （对比 R5F100FGAFP#10 (mid-density G13 member))
设计说明
Estimated: at 32 MHz, 3.3 V supply, and 100% CPU activity, the active current is approximately 32 MHz × 66 µA/MHz = 2.1 mA, plus peripheral leakage. Designers targeting deep STOP-mode duty cycles below 1% should ensure all unused peripherals are clock-gated in software, and the main regulator is the internal one (not the external EVdD pin) for lowest quiescent. Source: Renesas RL78/G13 family datasheet (66 µA/MHz, 230 nA STOP).
Place the 0.1 µF VdD decoupling capacitor within 5 mm of the VdD pin and a bulk 10 µF on each supply rail. Route the analog AVdD / AVss separately from digital VdD / Vss to keep digital switching noise out of the 10-bit ADC reference. The 64-LFQFP exposed pad (if present on the variant) should be soldered to a copper pour to drop theta_JA roughly 30% versus a non-thermal pad.
Do not exceed 5.5 V on any pin; the RL78 is a 1.6-5.5 V part and over-voltage damages the IO cells. When migrating between RL78/G13 suffixes (#10, #V0, #70, #X0), verify the data-flash size and pin-function remap tables in the matching hardware manual because some variants disable peripherals on certain pins. Always re-run IEC 60730 self-test firmware after a batch change even though the silicon is the same.
合规信息
RoHS and REACH compliance confirmed by Renesas product page and DigiKey listing. Not AEC-Q100 qualified (industrial/appliance grade, not automotive). IEC/UL 60730 class-B safety is supported by hardware features plus certified firmware libraries per Renesas RL78/G13 product page.
