R5F10MPGDFB#30 - 16-Bit RL78/I1B MCU 128KB Flash LQFP-100 | Renesas
MPN: R5F10MPGDFB#30 ✓ Hoạt độngR5F10MPGDFB#30 Tóm tắt
What is an RL78 microcontroller? The RL78 is Renesas's proprietary 16-bit core family that succeeds the legacy 78K0R and 78K0 lines, designed for low-power embedded applications. It sits inside the broader category of microcontrollers (MCU -> 16-bit MCU -> low-power MCU -> power-management-oriented MCU) and is purpose-built for metering, sensor conditioning, and human-machine interface (HMI) workloads.
Key differentiating features of the R5F10MPGDFB#30 include: (1) integrated 24-bit delta-sigma ADC with built-in phase correction and high-pass filter, eliminating the need for an external metering AFE; (2) low active current 96 uA/MHz and standby current 0.66 uA, extending battery life in line-powered and battery-backed meters; (3) RTC backup domain, allowing the calendar/clock to run while the CPU is halted; (4) high-accuracy 32 kHz oscillator support, which simplifies line-frequency measurement and tamper detection.
Technically, the RL78/I1B core uses a CISC Harvard architecture, three-stage pipeline, and a multi-channel DMA engine. The 128 KB of on-chip code flash supports in-system programming via a single-wire UART bootloader or the Renesas E1/E2 emulator. RAM (typically 8 KB on this family) and data flash (4 KB) are provided separately to allow EEPROM-like endurance without external storage.
Typical applications include single-phase and poly-phase electricity meters, smart energy meters with wired/wireless communication, gas/water meter endpoints, sensor transmitters with RTC logging, and low-power industrial sensor nodes. The integrated 24-bit sigma-delta AFE makes the #30 part specifically suited to billing-grade metrology.
Design tip: when migrating from older 78K0R designs, retain the original interrupt vector table layout because the RL78 core largely preserves it; however, port pin multiplexing differs - always re-validate the PCB layout against the LQFP-100 pin assignment in the Renesas datasheet rather than carrying over 78K0R footprints.
This page synthesizes distributor pricing, drop-in alternatives within the same LQFP-100 footprint, and practical design notes not found in the manufacturer datasheet - giving component buyers and design engineers a single-decision resource.

Ứng dụng tiêu biểu
R5F10MPGDFB#30 phù hợp cho 6 Áp dụngs: Single-Phase Electricity Meter, Poly-Phase Smart Energy Meter, Gas and Water Meter Endpoint, Low-Power Industrial Sensor Node, Smart Home Energy Monitor, PV Inverter / Solar Micro-Inverter.
Single-Phase Electricity Meter
The R5F10MPGDFB#30's integrated 24-bit delta-sigma A/D converter, on-chip phase adjustment circuit, and programmable high-pass filter make it purpose-built for single-phase active and reactive energy measurement. With active current of 96 uA/MHz and standby current of 0.66 uA (Halt mode, 32 kHz oscillator and RTC running), the part holds metrology accuracy across long battery backup periods and meets IEC 62053-21/22 class accuracy targets when paired with suitable current transformers. The 128 KB of code flash accommodates IEC-compliant metrology firmware, segmented LCD driver, and Tamper Detection.
Được đề xuất
Poly-Phase Smart Energy Meter
For three-phase four-wire smart meters, multiple R5F10MPGDFB#30 channels can be assigned - one per phase - to simultaneously sample voltages and currents while a host MCU coordinates communications. The 24-bit sigma-delta ADC delivers 0.1% measurement accuracy across the dynamic range required for billing-grade metrology. Hardware phase-correction eliminates trigonometric firmware overhead, freeing CPU cycles for DLMS/COSEM or wireless M-Bus protocol stacks; the 100-LQFP package fits standard meter mainboards with adequate copper area for power dissipation.
Được đề xuất
Gas and Water Meter Endpoint
Metering end-devices for gas, water, and heat are migrating to electronic metrology; the R5F10MPGDFB#30's 0.66 uA standby current extends battery life beyond 10 years when reporting hourly via wireless M-Bus or LoRaWAN. The integrated 24-bit ADC supports pulse-counting front-ends (e.g. from reed switches or optical encoders) and the RTC backup enables calendar-based tariff logic. Although analog flow metrology is simpler than electricity metering, the same 100-LQFP mechanical envelope simplifies factory tooling and inventory.
Được đề xuất
Low-Power Industrial Sensor Node
The R5F10MPGDFB#30 supplies a 16-bit CPU core, 128 KB flash, and 24-bit precision ADC for industrial sensor hubs that demand both measurement integrity and long battery life. Its 0.66 uA standby current draws negligible power during sleep, while RTC backup lets the node wake on calendar triggers rather than wasteful polling. The LQFP-100 footprint also provides abundant GPIO for digital sensor I/O alongside the analog front-end, removing the need for an external multiplexer on small-form-factor nodes.
Được đề xuất
Smart Home Energy Monitor
Whole-home energy monitors that report per-circuit consumption use the R5F10MPGDFB#30 because its on-chip 24-bit ADC can sample multiple CT channels in sequence with calibrated accuracy. Active current 96 uA/MHz keeps thermals inside the in-wall outlet enclosure, and the RTC domain supports local timekeeping even when the host WLAN is offline. The 128 KB flash stores calibration tables and load-disaggregation algorithms, and the LQFP-100 footprint fits commercial reference designs with 6-12 CT channels.
Được đề xuất
PV Inverter / Solar Micro-Inverter
Solar micro-inverters and string inverters require high-accuracy voltage and current sensing alongside MCU housekeeping; the R5F10MPGDFB#30's 24-bit sigma-delta ADC captures panel-side voltage and current with ~0.1% accuracy, while the 16-bit RL78 core executes MPPT and grid-synchronization firmware. The 100-LQFP package dissipates efficiently into the inverter heatsink or copper ground plane, and 96 uA/MHz active current keeps the meter-side consumption low - relevant for anti-islanding protection and DC-injection monitoring.

Ghi chú thiết kế
Use a 4.7 uF X7R ceramic decoupling capacitor on each VDD/AVDD pin plus a 0.1 uF HF bypass routed with minimal loop area; place them within 3 mm of each pin pair. The internal regulator (REGC, pin 83) requires a 1 uF decoupling cap on its own - omit only with caution. For battery-backed installations, the 0.66 uA standby current is achievable only when the application keeps the CPU in Halt mode with the 32 kHz crystal and RTC domain running; any peripheral left enabled (ADC, LCD, timers) will inflate standby current by orders of magnitude.
The LQFP-100 (14x14 mm) thermal envelope offers modest dissipation - the bottom exposed pad (EP, pin 100) must be soldered to a continuous ground pour that extends at least 4 mm^2 to dissipate internal regulator heat. Route all analog AFE traces on the top layer, guarded by AVSS on both sides; keep phase-correcting analog routing as short as practical and avoid crossing high-current or switched traces. The 32 kHz crystal traces should be short, ground-isolated, and free of crossing digital signals to preserve RTC accuracy for line-frequency measurement.
Estimated: at full 24 MHz operation in an inline meter reading continuously from the 24-bit AFE (sample rate 4 kHz), the part can dissipate ~30-40 mW; with VDD at 5 V and an uncontrolled ground plane, junction-to-ambient delta settles around +18C above ambient. In sealed meter enclosures at +55C ambient, this puts TJ around +73C - well inside the +85C commercial spec but leaves no headroom for higher VDD or fault-mode heating. Designers should compute worst-case power dissipation for the metrology firmware block and ensure a continuous EP ground pour is present to keep thermals in spec.
