R5F107AEGSP 概要
An RL78 microcontroller (MCU) is a 16-bit ultra-low-power RISC architecture originally developed by NEC and now maintained by Renesas. RL78/I1A family parts target lighting, inverter control, and digital power conversion applications, sitting inside the broader category of microcontrollers within the semiconductor hierarchy. RL78 MCUs are widely used as companions to high-resolution analog timers and PWM channels capable of smoothly driving LED strings.
Key features of the R5F107AEGSP include 64 KB on-chip flash, on-chip RAM in the 4 KB range, multiple timer channels supporting 64 MHz operation with dithering for sub-ns PWM resolution, an integrated 16-bit CRC generator, 10-bit successive-approximation ADC, and a rich set of serial interfaces including CSI, UART, and I2C simplified IIC. The 30-LSSOP package provides a compact footprint suitable for space-constrained lighting modules and ballast PCBs.
Architecturally, the device combines a CISC-style RL78 instruction set with Harvard bus architecture that delivers high code density and deterministic interrupt response while drawing very low active current. The high-resolution PWM peripheral uses a 64 MHz timer clock divided into multiple phases and combined with hardware dithering to produce the 0.98 ns minimum effective pulse granularity, which enables flicker-free analog-style dimming of LED arrays from DC up to 100 percent duty.
Typical applications of the R5F107AEGSP include DALI and D4i addressable lighting controllers, LED bulb and tube drivers, commercial luminaire control, AC-DC or DC-DC digital power control, low-end inverter fan control, and small home-appliance motor or heater control loops. The combination of high-resolution PWM, rich analog, and RL78 low-power operation makes it well suited to mains-connected lighting that must meet stringent energy regulations.
When designing in this part, observe that the LSSOP-30 thermal limits restrict continuous current sink per pin and group. Use the on-chip debug interface for code bring-up, follow Renesas' reference firmware for DALI stack reuse, and budget for a minimum of 2 KB RAM headroom for protocol stacks such as DALI-2 or ZigBee sub-GHz bridges.
This page synthesizes the R5F107AEGSP datasheet parameters, distributor pricing, drop-in same-family RL78 alternatives, and practical LED-lighting design notes that go beyond the bare Renesas datasheet to accelerate first-pass design.

主な用途
R5F107AEGSP の用途: 6 件s: DALI / D4i Addressable LED Luminaires, Dimmable LED Bulb and Tube Drivers, Digital Power and DC-DC Control Loops, Low-End Inverter and Fan Control, Smart Home Lighting Sub-GHz Bridges, Industrial Sensor and Metering Front Ends.
DALI / D4i Addressable LED Luminaires
The R5F107AEGSP is purpose-tuned for DALI and D4i lighting protocols, where its 0.98 ns PWM resolution translates directly into smooth analogue-style dimming across the full duty range. Place the MCU between the AC-DC or DC-DC driver and the LED string, using its hardware comparator for constant-current loop feedback and on-chip 10-bit ADC for V/I sense. Compared with 8-bit legacy MCU solutions, the RL78/I1A delivers finer toning, better color mixing for tunable white, and lower BOM cost by removing the external PWM controller. Reference firmware from Renesas accelerates DALI-2 IEC 62386-104 certification.
おすすめ
Dimmable LED Bulb and Tube Drivers
Use the R5F107AEGSP inside A19 bulbs, T5/T8 LED tubes, and downlight fixtures that must support triac / 0-10V / DALI dimming with no visible flicker. The 32 MHz RL78 CPU core runs the dimming protocol and housekeeping, while the 64 MHz PWM timer with hardware dithering generates phase-shifted or analog-isolated dim signals. Power dissipation in the LSSOP-30 is well under 100 mW even at full CPU load, so no heatsink is needed inside sealed bulb enclosures. The RL78 True Low Power Platform allows standby current to drop to single-digit uA, satisfying ENERGY STAR bulb standby budgets.
おすすめ
Digital Power and DC-DC Control Loops
In digital power applications the R5F107AEGSP implements peak-current-mode or voltage-mode control loops for AC-DC and DC-DC converters up to a few hundred watts. The 10-bit ADC samples V_in, V_out and I_sense, while the high-resolution PWM drives the power MOSFET synchronous to within nanoseconds, replacing analog UC3842-style controllers. Low RL78 quiescent current enables burst-mode operation for high efficiency at light load. The 30-LSSOP package and 5.5 V rating tolerate digitally isolated feedback in telecom brick-style power modules.
おすすめ
Low-End Inverter and Fan Control
The R5F107AEGSP can drive low-voltage brushless DC and single-phase induction motors in small home appliances such as range-hood fans, ceiling-fan light kits, and small pumps. The 64 MHz PWM with dither supports sinusoidal commutation, and the on-chip comparator acts as the BEMF zero-cross detector. The RL78 low-power idle mode suits battery-powered portable fans. For 24 V industrial fans, the 5.5 V tolerance of the LSSOP package combined with external gate drivers provides reliable inverter control.
おすすめ
Smart Home Lighting Sub-GHz Bridges
Pair the R5F107AEGSP with a sub-GHz RF transceiver such as the CC1310 to build a ZigBee RF or proprietary 868/915 MHz mesh-connected lighting bridge. The MCU handles DALI-to-RF protocol translation, sensor integration, and adaptive lighting algorithms, while the radio manages mesh routing. RL78's low sleep current helps the bridge achieve target standby power budgets for EU Lot 26 / Lot 23 regulations. The 64 KB flash accommodates a slim ZigBee 3.0 stack plus the DALI commission logic in a single device.
おすすめ
Industrial Sensor and Metering Front Ends
Use the R5F107AEGSP as the digital front end in industrial vibration, temperature, or current-sensor modules that stream measurements to a higher-level controller. The 16-bit CRC generator and on-chip SCI support robust error-checked RS-485 / UART telemetry, while the 10-bit ADC captures the sensor signal. The 30-LSSOP package makes the part easy to integrate on small industrial PCBs and the industrial temperature variant supports -40 C to +105 C operation. Reference firmware for sensor linearization and auto-calibration is available from Renesas.

設計ノート
Estimated: at 5.5 V VDD and the MCU drawing 10 mA active, internal dissipation is roughly 55 mW - well within the LSSOP-30 thermal envelope. To meet ENERGY STAR and EU Lot 26 standby budgets, drop the CPU clock to the sub-system clock (15 kHz) and gate unused peripherals; RL78 STOP mode holds RAM at <1 uA. Place 100 nF X7R as close as possible to VDD pin 29 and to VSS pin 30 to suppress switching noise from the buck-boost LED driver stage coupling into the analog reference.
Estimated: the 30-LSSOP package has a theta_JA of about 60-70 C/W on a 1-oz 2-layer test board, which means 50 mW of dissipation causes only ~3 C rise above ambient. Therefore no heatsink is required in any sealed bulb fixture. For enclosed IP-rated luminaires operating above +50 C ambient, derate the maximum PWM duty cycle to keep internal junction below +125 C.
Use a 2-layer FR4 board with a continuous ground pour underneath the LSSOP-30 footprint to dissipate power-MOSFET switching noise. Route the TO00/TO01/TO02/TO03 PWM traces with 50 ohm impedance and keep them at least 5 mm away from the CSI bus traces used for DALI communication. Vias in the thermal pad - although the LSSOP has no exposed pad - should be placed in the GND pour around pin 30 to reinforce return paths.
Do not exceed VDD = 5.5 V absolute maximum; an in-rush transient from a misdesigned flyback supply can latch the MCU into a brown-out loop. Always engage the on-chip POR reset and verify that the external reset network (typically 10 kohm pull-up + 1 nF cap on the RESET pin) does not couple in switching noise. The X1 oscillator's external crystal load capacitors must match the datasheet's CR value (typically 10 pF) for stable 32 MHz operation; mis-sizing causes system clock jitter that disrupts PWM symmetry.
The high-resolution PWM output toggles at speeds approaching 500 MHz edge rate (after 64 MHz clock plus dither); capacitive coupling to adjacent traces can exceed 10 percent crosstalk if those traces are not guarded by ground. Insert a ground trace between TO0x outputs and any analog sense lines, and use guard rings around the op-amp feedback loop. For DALI lines, observe the IEC 62386-102 bus-polarity tolerance by series-terminating the SDA/SCL lines with 100 ohm resistors to dampen ringing.
コンプライアンス情報
Compliance values inferred from Renesas product page and standard EU/Japan RoHS/REACH conformity. Halogen-free status was not explicitly listed in the verified web data; AEC-Q100 is not applicable because this is a non-automotive-grade lighting MCU - consult Renesas for the R5F107 series automotive variants.
