R5F10MPGDFB#30 - 16-Bit RL78/I1B MCU 128KB Flash LQFP-100 | Renesas

The Renesas R5F10MPGDFB#30 is a 16-bit microcontroller from the RL78/I1B family, featuring a 24 MHz CPU, 128 KB of flash memory, and housed in a 100-pin LQFP (14x14 mm) package. It is engineered primarily for electricity meter and energy-measurement applications, integrating a 24-bit delta-sigma A/D converter, phase adjustment circuits, high-pass filter, and a high-accuracy oscillator for meter metrology. The device operates across -40C to +85C, supports 1.65V to 5.5V supply, and achieves ultra-low power consumption of 96 uA/MHz active and 0.66 uA standby (Halt mode with 32 kHz oscillator and RTC backup on). 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.

The R5F10RJAAFA#V0 belongs to the RL78 family of microcontrollers, a 16-bit CISC architecture developed by Renesas as a low-power successor to the 78K and R8C families. An MCU (microcontroller unit) is a single-chip computer integrating CPU, memory, and peripherals; the RL78/L12 sub-series specifically targets small appliances, healthcare devices, and other cost-sensitive LCD-based applications where ultra-low standby current is critical. Key features include True Low Power Platform technology achieving 75 µA/MHz active current and 0.64 µA for RTC + LVD standby, three selectable LCD driving voltage generation methods (external resistance division, capacitive split, and internal voltage boost), and integrated safety peripherals. The 16-bit CISC core delivers 31 DMIPS at 24 MHz while consuming a fraction of the power of competing 8/16-bit cores. The architecture uses a Harvard-style bus with unified register bank that lets the compiler treat ROM, RAM, and SFRs as one address space, accelerating context switching and interrupt response. A built-in 8-channel 10-bit ADC, multiple timers, RTC, UART, I2C, and CSI simplify BOM cost by eliminating external chips. The device supports 4.5 KB RAM plus 2 KB data flash for non-volatile user storage. Typical applications include white goods (washing machines, microwave ovens), healthcare devices (blood-pressure monitors, glucose meters), industrial segment-LCD instrumentation, smart thermostats, and battery-powered consumer electronics. The wide 1.6 V – 5.5 V supply range lets the same part run from a single 3 V coin cell or a regulated 5 V rail. When designing with the R5F10RJAAFA#V0, choose the LCD driving method based on panel size: capacitive split for small panels, internal voltage boost for medium panels up to 5 V, and external resistor division for large panels or when precise contrast adjustment is required. The TOOLCHAIN is supported by the free e2 studio IDE plus the CC-RL compiler.

It is part of Renesas' True Low Power Platform, achieving as low as 75 uA/MHz active current and 0.64 uA for RTC plus LVD operation, with a 1.6 V to 5.5 V supply range that supports battery-powered segment-LCD products. A microcontroller (MCU) is a single-chip computer that integrates a CPU core, non-volatile program memory (Flash), working RAM, peripheral set, and I/O into one package. The RL78 is Renesas' 16-bit CISC core family succeeding the 78K0R; the L12 sub-family specifically adds an integrated segment-LCD driver, multi-channel 10-bit ADC, comparator, RTC, and low-voltage detector (LVD). The MPN suffix RJC denotes a 52-pin LQFP, 32 KB Flash / 2 KB RAM variant. The #V0 trailer indicates the standard industrial temperature grade (-40C to +85C) and standard lead-free / RoHS-compliant shipping packaging. Key specifications include 31 DMIPS (Dhrystone MIPS) at 24 MHz, three LCD voltage-generation methods (external resistor divider, capacitive charge pump, internal voltage boost) for compatibility with resistive and high-capacitance LCD panels, and built-in RTC + LVD that together draw only 0.64 uA. The on-chip segment-LCD driver supports up to 4 common x 39 segment (or 8 common x 35 segment) outputs depending on pin allocation, allowing direct connection of low-power glass displays. The RL78/L12 uses a Harvard-architecture RL78 core with single-cycle 16-bit ALU, hardware multiplier, and three-stage pipeline. The peripheral set is tailored to battery-operated LCD instruments: a 24 MHz high-speed on-chip oscillator, 15 kHz low-speed oscillator, 10-bit successive-approximation ADC with internal reference, two operational amplifiers / comparators, multiple 16-bit timers, a real-time clock with calendar, an interval timer, and DMA. Flash programming is supported in-circuit via single-wire UART or UART0 bootloader. Typical applications include battery-powered home appliances (microwave ovens, washing machines, induction cooktops, rice cookers), healthcare devices (blood-pressure monitors, glucose meters, thermometers), metering and industrial segment-LCD instruments (utility meters, thermostat displays), portable consumer electronics with LCD readouts, and any 1.6 V - 5.5 V product that needs an on-chip segment LCD. Designers select the L12 over the L13/L1C sub-families when the application needs the lowest possible standby current with an integrated LCD controller. When designing with this device, populate both VDD and VLCD with low-ESR ceramic decoupling and a bulk reservoir capacitor near the IC. Use the LCD voltage-generation mode that matches the panel: capacitive split for low-multiplex 1/4 bias displays, internal voltage boost for high-multiplex panels at low temperature. Enable the LVD to ensure deterministic reset during battery brown-outs and use the RTC's sub-second interrupt to wake the CPU periodically for sensor reads - this combination yields years of operation from a single CR2032 cell.

It targets low-power applications requiring on-chip segment LCD control, such as home appliances, energy meters, and measurement devices, with operation from 1.6 V to 5.5 V supply. What is a 16-bit MCU? A 16-bit microcontroller (MCU) is a single-chip computer that processes instructions and data over a 16-bit data bus, sitting between 8-bit entry-level MCUs (e.g., PIC16, ATmega) and 32-bit Cortex-M parts in the embedded hierarchy. The RL78 core extends this category with an enhanced three-stage pipeline, ultra-low-power RUN/STOP/HALT/SNOOZE modes, and on-chip peripherals like 12-bit ADCs, comparators, and segment LCD controllers — placing it under the broader taxonomy: MCU -> microcontroller -> embedded processor -> semiconductor IC. The RL78/L13 sub-family specifically targets segment-LCD human-machine-interface applications. Key features include 128 KB (128K x 8) flash program memory, configurable RAM/data flash, a 24 MHz maximum CPU clock, an integrated segment LCD driver (up to 8 common x 40 segment), a 12-bit A/D converter with up to 12 channels, multiple low-power modes (STOP, HALT, SNOOZE), and a wide 1.6 V–5.5 V operating range. Per the Renesas product page, this part is suitable for LCD display of home appliances or measurement devices, and it operates over the -40 °C to +85 °C industrial temperature range. From an architectural standpoint, the RL78 core uses a Harvard-style bus with separate program flash and SRAM paths, supports the 78K0R-compatible instruction set, and provides hardware multiply/divide plus a low-power on-chip oscillator that removes the need for an external crystal in many designs. The on-chip segment LCD driver generates the necessary AC bias waveforms internally, eliminating external charge-pump circuitry for static, 1/3, and 1/4 duty LCD glass. Typical applications include home appliance control boards (washing machines, microwave ovens, induction cookers), smart electricity/water/gas meters, HVAC thermostats, white-good user-interface panels, industrial measurement equipment with segment LCD readouts, and battery-powered sensor readouts. The integrated segment LCD driver reduces BOM by replacing external LCD bias ICs. When designing with this device, plan for decoupling capacitors near the VDD/VSS pins, leave the TOOL0 pin accessible for in-circuit debugger connection, and verify the segment/comment pin assignment matches your LCD glass map in the e2 studio / CS+ pin configurator. Power sequencing and SNOOZE-mode entry are configured in the Smart Configurator code-generation toolchain rather than via runtime registers.

R5F10WMGAFB#30 - RL78/L13 16-bit MCU 128KB Flash | Renesas
R5F10WMGAFB#30

R5F10WMGAFB#30 - RL78/L13 16-bit MCU 128KB Flash | Renesas

The Renesas R5F10WMGAFB#30 is a 16-bit RL78/L13 microcontroller integrating 128 KB of code Flash, 8 KB of SRAM, and a built-in LCD controller/segment driver in an 80-pin LQFP package. It runs at up to 24 MHz from an internal oscillator and is targeted at low-power, battery-driven human-machine-interface applications such as home appliances and metering equipment. An RL78 microcontroller is a low-power 16-bit CISC core designed by NEC/Renesas as the successor to the 78K0 family. RL78 cores are tightly integrated with precision analog, LCD segment drivers, and multiple low-power operating modes. The RL78/L13 sub-family is the dedicated variant for applications with on-glass or on-board segment LCD displays, sitting within Renesas's broader RL78 product pyramid: RL78 core -> RL78/L1x (LCD) -> RL78/L13 (mid-density). This positioning makes the part a benchmark for years-of-battery-life white goods. Key features include three on-chip low-speed on-chip oscillators (15 kHz, 32 kHz, and the main 24 MHz high-speed on-chip oscillator), a 5-channel internal voltage booster for LCD bias, hardware multiplier/divider, 10-bit successive-approximation ADC, and a rich serial complement (CSI/SPI, UART, I2C, and LIN-bus). Power consumption is exceptionally low: approximately 0.6 µA in STOP retention mode with the LCD operating on a 32 kHz subclock and only ~3 mA active at 24 MHz. Architecturally, the RL78/L13 pairs a 3-stage pipeline CISC core with separated code/data buses (Harvard-style) and is built on a 130 nm mixed-signal process with embedded EEPROM/Flash. The integrated LCD controller supports up to 35 segment outputs x 4 common (or 39 x 8) configurations, configurable bias and frame frequency, and internal charge-pump or resistor-divider bias generation to allow operation from a single 1.8 V to 5.5 V supply. Typical applications include white-good HMI boards (washing-machine, microwave, induction-cooktop panels), residential gas/water/heat meters with display, blood-pressure and household medical displays, and remote-control units with battery charging indication. When designing with the R5F10WMGAFB#30, place the decoupling capacitors as close as possible to the VDD/VSS pins and reserve at least one full PCB layer for the LCD segment-trace routing. Selecting the correct bias source (internal resistor divider vs external capacitor divider) is critical - misconfiguring the charge pump on high-multiplex panels causes ghost segments.

The platform inherits from the broader 16-bit MCU category (microcontroller -> embedded processor -> semiconductor IC), making it a logical step up from 8-bit controllers for applications demanding more deterministic motor commutation. Key specifications include 64KB (64K x 8) Flash for program storage, 4KB RAM (typical for this family), an internal 32MHz high-speed oscillator with PLL, multiple serial interfaces (UART, I2C, CSI/SPI), a 12-bit A/D converter, on-chip comparator and programmable gain amplifier, plus hardware multiplier/divider. The 64-LFQFP-10x10 package provides ample analog and digital pin assignments for three-phase motor drive plus keypad/LED matrix scan expansion, while industrial-grade -40C to +85C operation allows deployment in white goods, factory automation and outdoor equipment. Typical applications include sensorless BLDC motor control for small fans, pumps, compressors and appliance inverter boards, consumer electronics such as hair dryers and air purifiers, and industrial motor subsystems. The chip's integrated PGAs and comparators reduce bill-of-materials by eliminating several external op-amps that discrete BLDC designs would require. When designing with the R5F11BLEAFB#30, allocate sufficient PCB area for the analog ground island and keep the analog VDD/AVSS traces short. Renesas provides the RL78/G1F hardware manual and motor control support software packages for fast code ramp-up. This RL78/G1F family is optimized for sensorless BLDC motor control but should be evaluated against newer RA or RX families for designs needing ARM Cortex or higher-performance DSP extensions.

The Renesas R5F51308ADFN#30 is a cost-optimized, high-performance 32-bit RX130 microcontroller built around the RXv1 CPU core, delivering 50 DMIPS at 32 MHz and integrating 512 KB of flash memory plus 48 KB of SRAM. The device is housed in an 80-pin LFQFP (12x12 mm) package and operates from a single 1.8 V to 5.5 V supply, supporting both battery-powered and 5 V industrial rails. A microcontroller (MCU) is a single-chip computer that integrates a CPU core, non-volatile program memory (flash), volatile working memory (RAM), and a wide range of peripheral interfaces such as ADC, timers, communication controllers, and capacitive-touch hardware. The RX130 sits inside the broader Renesas RX family (RX100/RX200/RX600/RX700) and is positioned as the cost-optimized, ultra-low-power entry tier with on-chip touch sensing. LDOs, op-amps, and reset supervisors are typically placed around the RX130 to build a complete power-tree for human-machine interface (HMI), home appliance, and industrial-sensor designs. Key features include up to 36 channels of capacitive touch sensing with improved noise immunity, sensitivity, and water resistance versus previous RX touch generation, a 12-bit A/D converter, a D/A converter, a real-time clock (RTC), IEC60730 compliance for appliance-safety code libraries, and up to 6 communication channels. The wide 1.8 V to 5.5 V supply range allows direct connection to 5 V sensors and human-machine interface panels without level shifters. An integrated RTC and low-power modes make standby power budgets achievable for battery-operated appliances. The RXv1 core is paired with single-precision FPU hardware support and tightly-coupled flash that supports zero-wait-state execution at 32 MHz, giving 50 DMIPS performance suitable for user-interface controllers, sensor fusion, and small protocol stacks. The capacitive-touch peripheral runs autonomously from the CPU, leaving the core free for application logic and reducing interrupt load in noisy environments. Hardware IEC60730 class-B support accelerates functional-safety certification for white goods. Typical applications include home appliance user interfaces with touch keys, industrial control panels, battery-powered sensor nodes, building automation keypads, and small motor-control boards that need ADC plus timer resources on a single 5 V rail. The 80-pin LFQFP exposes ample GPIO for parallel displays, button matrices, and brushless-DC FET drivers. When designing with the RX130, place the decoupling network as close as possible to the power pins, route touch-sensing traces with guard rings, and confirm IEC60730 firmware libraries are linked when targeting white-goods safety standards. Always validate the touch-sensing threshold with the production PCB stack-up.

R5F51308ADFP#30 - RX130 32MHz 512KB Flash MCU | Renesas

The Renesas Electronics R5F51308ADFP#30 is a 32-bit RX130 microcontroller running at 32 MHz with 512 KB Flash and 48 KB SRAM, housed in a 100-pin LFQFP (14x14 mm) package. It is part of the RX130 family - a cost-optimized, high-performance 32-bit MCU group with enhanced capacitive touch key function and 5 V operation support, delivering up to 50 DMIPS per the verified distributor listings. A microcontroller (MCU) is a single-chip computer containing a CPU core, program memory (Flash), data memory (SRAM), and on-chip peripherals such as timers, communication interfaces, ADCs, and touch sensing. MCUs form the lowest tier of the embedded computing hierarchy: embedded processor -> microcontroller -> 32-bit MCU -> RX130 family. They sit beneath microprocessors (MPUs) in capability but above discrete logic in integration, enabling compact, low-power designs for appliance, industrial, and human-machine-interface (HMI) products. Key features of the R5F51308ADFP#30 include 88 I/O pins (per JLCPCB listing), a 12-bit A/D converter with up to 36 capacitive touch sensing channels, an 8-bit D/A converter, 6 communication channels (including SCI, I2C, and SPI variants), an RTC, IEC60730 compliance support for household appliance safety standards, and a wide 1.8 V to 5.5 V single-supply operating range. The device uses the proprietary RXv1 CPU core with single-precision FPU. The RX130 architecture combines deterministic interrupt response with low-power operation, making it well suited for white goods, sensor HMI, and battery-friendly IoT edge nodes. The integrated touch sensing unit uses an improved mutual-capacitance detection method providing better noise immunity, sensitivity, and water resistance versus earlier Renesas touch MCUs. Typical applications include washing machine and refrigerator control boards, induction cooktop user interfaces, smart thermostat keypads, industrial sensor HMI panels, and small IoT sensor hubs. The wide 5 V tolerance simplifies interfacing with legacy analog front-ends and white-goods actuator drivers. When designing with this part, remember that the R5F51308ADFP#30 is the 100-pin / 512 KB / -40C to +85C industrial-grade variant. For lower pin counts, smaller flash, or extended temperature (-40C to +105C) refer to other RX130 group members listed in the family datasheet (R01DS0243EU0300).

R5F52203BDFL - 32MHz 32-bit RX220 MCU, 64KB Flash, LQFP-48 | Renesas

The Renesas Electronics R5F52203BDFL is a 32-bit RX220 family microcontroller built on the RXv1 core, delivering 32 MHz CPU performance with 64 KB of on-chip flash and 8 KB of SRAM in a 48-pin LFQFP (7x7 mm) package. It is an entry-level RX200 MCU positioned for designs needing minimum peripheral count, low active power, and small footprint. An entry-level 32-bit MCU (microcontroller unit) integrates a CPU core, on-chip flash program memory, SRAM, and a curated set of peripherals into a single IC. Within the broader hierarchy it sits between 8/16-bit legacy MCUs and high-performance Cortex-M/RX700 parts. The RX220 series in particular is the slimmed-down, low-pin-count derivative of the RX210 family, retaining pin-compatibility and the same RXv1 instruction set while trimming unused peripherals to reduce cost and active current. Key features include 64 KB (64K x 8) flash, 8 KB SRAM, up to 32 MHz CPU clock, a 12-bit A/D converter, multi-function timer (MTU2), and serial interfaces (SCI, I2C-bus compatible, RSPI). Supply voltage spans 1.8 V to 5.5 V, supporting both 3.3 V and 5 V system rails. The device also integrates watchdog timer, real-time clock, low-voltage detection, and on-chip debugging via a single-wire interface. Architecturally, the RX220 uses a 3-stage pipelined RXv1 core with hardware MAC (multiply-accumulate) instructions, supporting C-level DSP routines without an extra DSP unit. The 1.8 V internal core regulator and selectable low-power modes (Sleep, Deep Sleep) reduce quiescent current to a few microamps, enabling coin-cell powered designs. Typical applications include consumer appliances, sensor signal conditioning, battery-driven IoT nodes, low-end motor control, and human-interface boards replacing 8/16-bit MCUs. The wide 1.8-5.5 V supply simplifies migration from 5 V legacy systems. Consider total power budget: at 32 MHz active and 3.3 V, the core draws several mA, so duty-cycling is essential for battery lifetime.
