R5F1007AANA - 16KB Flash RL78/G13 MCU, 24-HWQFN | Renesas

The Renesas R5F1007AANA is a 16-bit RL78/G13 general-purpose microcontroller with 16KB code flash and 32MHz CPU speed, housed in a 24-pin HWQFN (4x4 mm) package. It features 2KB SRAM, 4KB data flash, and integrates a 12-bit A/D converter, comparators, timers, and serial interfaces. According to the manufacturer datasheet, this part delivers 41 DMIPS at 32 MHz while consuming only 66 µA/MHz active, and draws as little as 0.57 µA in RTC+LVD standby, making it one of the industry's lowest-power 16-bit MCU platforms. An RL78 MCU is a low-power 16-bit CISC microcontroller family from Renesas designed for general-purpose embedded applications. The RL78/G13 sub-family adds a wide 1.6V-5.5V operating range, 16KB to 512KB code flash variants, and built-in safety features such as a watchdog timer, RAM parity, and a clock-monitoring circuit. The architecture combines a three-stage pipelined CPU with multiply/divide hardware, a low-power on-chip oscillator, and a high-precision (±1%) 15 kHz LOCO for RTC operation. Key features include an 8-channel 12-bit A/D converter with internal/external reference, two 8-bit D/A converters, up to 16KB code flash with 4KB data flash, 2KB SRAM, multiple serial interfaces (CSI/UART/I2C), and up to 20 GPIO. An on-chip voltage detector (LVD) and a real-time clock (RTC) with calendar function enable battery-backed timekeeping, while the integrated low-power modes (HALT, STOP, SNOOZE) reduce average current consumption to microamp levels for energy-harvesting or battery-powered designs. The RL78/G13 core uses a 16-bit CISC architecture with 74 base instructions and a 1.6 µs interrupt response at 32 MHz. It supports C-friendly development via the e2 studio IDE with the CC-RL compiler and works seamlessly with Renesas' Applilet code-generator. The 24-HWQFN package provides a compact 4x4 mm footprint with an exposed die pad for thermal dissipation. Typical applications include battery-powered sensor nodes, home appliances (washing machines, microwave ovens), industrial metering, HVAC thermostats, healthcare monitors, and remote controls. The wide operating voltage range and integrated peripherals reduce the need for external components, lowering BOM cost in space-constrained designs. When designing with the R5F1007AANA, pay attention to the 24-HWQFN PCB layout: thermal pad soldering must follow JEDEC J-STD-020 reflow profiles, and the decoupling capacitors should be placed within 3 mm of the VDD/VSS pins. The RL78/G13's SNOOZE mode enables peripheral-triggered wake-up without CPU intervention, which is critical for ultra-low-power sensor applications.

R5F1007AANA#U0

R5F1007AANA#U0 - RL78/G13 16-bit MCU, 16KB Flash, 24-HWQFN | Renesas

The Renesas R5F1007AANA#U0 is a 16-bit RL78/G13 microcontroller with 16 KB of code flash, 2 KB of SRAM, and 4 KB of data flash, housed in a 24-pin HWQFN (4 x 4 mm) package with an exposed thermal pad. It runs at up to 32 MHz (43.2 DMIPS) and supports a wide 1.6 V to 5.5 V operating voltage range, drawing only 66 uA/MHz while the CPU is active and 230 nA in STOP standby with RTC retention. What is a 16-bit microcontroller? A microcontroller (MCU) is a single-chip computer that integrates a CPU core, program memory (typically flash), working RAM, and a set of on-chip peripherals such as ADCs, timers, and serial interfaces. The RL78 family uses the 16-bit RL78 CISC core, an evolution of the legacy 78K architecture, optimised for ultra-low power general-purpose applications. Within the broader semiconductor hierarchy, an MCU sits under embedded controllers -> microcontrollers -> microprocessors -> digital ICs -> semiconductors, and the RL78/G13 specifically targets low-power, high-function general-purpose household and industrial designs. Key features include a 10-bit successive-approximation ADC, up to 16-channel PWM timers, multiple serial interfaces (CSI/UART/I2C), an on-chip high-speed on-chip oscillator, and a built-in safety function (hardware illegal-operation detector) tailored for appliance safety standards. The data flash block (typically 4 KB) supports byte-erase and byte-program operation, useful for storing user calibration data without external EEPROM. The RL78/G13 architecture uses a three-stage pipeline and Harvard-style bus topology (separate 16-bit instruction and 8-bit data paths) that yields 43.2 DMIPS at 32 MHz while idling at MCU-class low-power levels. Internal voltage regulation from a single 1.6 V to 5.5 V supply allows direct battery (e.g., 2 x AA) or USB-bus operation; on-chip debug and serial programming use a single-wire TOOL0 interface, eliminating any external debug port hardware. Typical applications include household appliances (washing machines, rice cookers, microwave ovens), low-power IoT sensor nodes, battery-powered metering and remote-control units, and white-goods control boards. The wide operating-voltage window and sub-microamp STOP current make the part attractive for any product that must survive months on batteries. When designing with this device, keep the exposed thermal pad soldered to a continuous ground pour to provide both thermal relief and a low-impedance return for the high-speed on-chip oscillator; respect the 5.5 V absolute maximum on any I/O pin and add ESD clamps on user-accessible connectors.

The Renesas R5F1007CANA is a 16-bit RL78/G13 microcontroller featuring 32KB code flash, 32MHz CPU, and 24-HWQFN (4x4mm) package. It operates from 1.6V to 5.5V with the industry's lowest active current of 66 μA/MHz, STOP-mode standby of 230 nA (or 0.57 μA with RTC and LVD running), and delivers up to 41 DMIPS at 32 MHz. The part is built around the RL78 16-bit CISC core with a 3-stage pipeline, hardware multiplier, and zero-wait flash access. An RL78/G13 microcontroller is a general-purpose 16-bit MCU that combines ultra-low power consumption (ULP) with rich analog and digital peripherals. It belongs to the wider RL78 family of microcontrollers (synonym: low-power 16-bit MCU, ultra-low-power MCU, ULP microcontroller), which in turn are part of the broader category of microcontrollers (MCU) within the integrated circuits (IC) hierarchy used in embedded systems. The RL78/G13 platform is positioned for battery-powered and always-on applications where the MCU spends most of its life in a low-power state but must wake quickly to handle user events. Key features of the R5F1007CANA include on-chip data flash for parameter storage, a 10-bit successive-approximation A/D converter with multiple input channels, configurable 16-bit timers, real-time clock (RTC), low-voltage detection (LVD), UART, CSI/SPI, and I²C interfaces. Hardware safety functions such as illegal-memory-access detection and a clock monitor support IEC/UL 60730 class B household-appliance safety certification. The device includes an on-chip oscillator and supports low-power modes HALT, STOP, and SNOOZE. The R5F1007CANA uses a 24-pin HWQFN (4x4mm) plastic-encapsulated leadless package with an exposed thermal pad, which provides a compact footprint for space-constrained designs. Power-supply architecture is simple: a single 1.6–5.5 V rail directly powers VDD, and internal LDO regulators derive the core voltage, eliminating the need for external regulation. Typical applications include home appliances (washing machines, microwaves, induction cookers), battery-powered IoT sensors, smart meters, HVAC controls, and consumer electronics. The wide operating voltage range lets it run from a single 1.5V cell or two 1.5V cells, while the low STOP current extends shelf life and runtime for energy-harvesting or coin-cell systems. When designing with this device, allocate the smallest-possible decoupling capacitor (typically 0.1 µF ceramic) as close as possible to the VDD/EVDD pins, and tie unused I/O pins to a defined logic level to minimize leakage. The SNOOZE mode can wake the CPU on a UART or A/D event without a full clock restart, cutting average system power substantially in always-listening designs.

The architecture pairs a 3-stage pipelined RL78 CISC core with 256-byte register banking, accelerating C code execution while the on-chip DTC (Data Transfer Controller) offloads peripheral-to-memory and memory-to-memory moves. Hardware CRC, a watchdog timer with dedicated on-chip oscillator, and illegal-memory-access detection provide a layer of functional safety that is rare in this price tier. Typical applications include white goods and home appliances (washing machines, microwave ovens, refrigerators), battery-powered IoT sensors, HVAC thermostats, smart meters, industrial sensor nodes, and remote controls. The wide 1.6V-5.5V supply range and sub-µA standby make it well suited to energy-harvesting or battery-replacement products. When designing with this device, allocate at least one decoupling capacitor (0.1 µF plus 10 µF bulk) per VDD/AVSS pair, place the 32.768 kHz crystal close to the X1/X2 pins if sub-µA RTC operation is required, and reserve the TOOL0 pin for an on-board debug header. Pin assignment is identical across RL78/G13 24-pin HWQFN family parts, simplifying PCB reuse.

R5F100LJGFB#30

R5F100LJGFB#30 - 16-bit RL78/G13 MCU 256KB Flash LQFP-64 | Renesas

The Renesas R5F100LJGFB#30 is a 16-bit RISC microcontroller belonging to the RL78/G13 family, integrating 256 KB of code Flash and 32 MHz CPU performance delivering 43.2 DMIPS in a 64-pin LFQFP (10x10 mm) surface-mount package. The part is specified for the industrial temperature range of -40C to +105C and operates from a 1.6 V to 5.5 V supply, balancing ultra-low active current (66 uA/MHz) with a deep STOP standby current of only 230 nA. A microcontroller (MCU) is a single-chip computer that combines a CPU, memory (Flash/RAM), and programmable peripherals into one device. The RL78/G13 line targets general-purpose embedded applications and sits within the broader hierarchy of 16-bit microcontrollers -> microcontrollers -> embedded processors -> semiconductor ICs, all of which fall under the larger power-management-aware computing umbrella. The Renesas RL78 architecture is the successor to the legacy 78K and R8C lines, optimized for ultra-low-power household, industrial and sensor-driven applications. Key features that differentiate this 256 KB part from sibling RL78/G13 members include 20 KB of on-chip SRAM, 4 KB data Flash (with background and block-erase capability), an on-chip 32 MHz oscillator plus 15 kHz and 125 kHz low-speed oscillators, an 8-channel 10-bit successive-approximation ADC, multiple 16-bit timers, a real-time clock, a DMA controller (4 channels), and an IEC/UL 60730-compliant safety core (illegal-Memory-access detection). Communication peripherals include CSI/SPI, I2C and UART channels, supporting LIN and other fieldbus bridges via software. The RL78 core uses a three-stage pipelined CISC-RISC hybrid with a 1-byte instruction fetch and dedicated register banks, which is why DMIPS/MHz is unusually high (1.35 DMIPS/MHz) compared with classic 8051 cores. The on-chip voltage regulator supports operation down to 1.6 V, allowing direct connection to a 2x AA alkaline battery stack with no external LDO and retaining data in STOP mode for years. Typical uses for the R5F100LJGFB#30 are household appliances (washing machine control boards, induction cookers, microwave ovens), smart metering, sensor conditioning, battery-powered IoT nodes, white goods user interfaces, and industrial HVAC controllers where the IEC 60730 functional-safety requirement and STOP current budget dominate the design. Design consideration: when migrating from a smaller Flash variant (e.g. R5F100LEAFB or R5F100LF), confirm the bank-to-pin mapping for the 64-LFQFP code, since the 64-pin package has three fewer I/O than the 80- and 100-pin versions of the same family.

The 5.5V wide operating range supports direct battery and industrial bus connection. A microcontroller (MCU) is a single-chip computer containing a CPU, memory (Flash/RAM), and programmable peripherals on one silicon die. Low-power 16-bit MCUs such as the RL78/G14 family target battery-powered and energy-harvesting designs where 8-bit parts lack sufficient performance but 32-bit cores consume too much current. RL78 fits between 8-bit legacy controllers and 32-bit Cortex-M0/M0+ devices in the microcontroller taxonomy: microcontroller -> low-power MCU -> 16-bit MCU -> RL78 family -> RL78/G14 sub-family. Key features include 64KB code Flash, 4KB SRAM, 5.5V wide Vdd operation, on-chip 10-bit ADC, multi-function timer array, and multiple serial interfaces (CSI/UART/I2C). The 32 MHz CPU delivers up to 0.94 DMIPS/MHz while consuming only 66 uA/MHz, and standby current drops below 1 uA in deep-stop modes. Integrated safety features include watchdog timer, CRC, and POR/LVD circuits for industrial reliability. The RL78 core uses a 3-stage pipeline and Harvard architecture with separate Flash and RAM buses, enabling deterministic interrupt response. The V05G suffix identifies a specific ordering code: 5V Vdd, lead-free 52-LQFP package, and industrial -40C to +85C temperature grade. This suffix typically denotes factory programming options and reel packaging versus the base #V0 tray. Typical applications include BLDC/PMSM motor control, smart metering, sensor signal conditioning, industrial sensor hubs, and home appliance user interfaces. The wide 5.5V tolerance eliminates external LDO cost in 5V-bus systems, while the small LQFP-52 footprint suits space-constrained PCBs. Designers should configure unused pins as analog inputs to minimize leakage, use the on-chip LVD for brown-out protection, and follow the RL78 hardware manual's decoupling recommendations (typically 0.1 uF plus 10 uF bulk near VDD pins). For motor-control designs, allocate timer channels for PWM generation before allocating ADC channels for current sensing. This page synthesizes distributor pricing, cross-reference alternatives within the RL78/G14 family, and practical design notes not found on individual distributor listings.

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.

R5F10WLCAFB

R5F10WLCAFB - 16-Bit 24MHz RL78/L13 MCU 32KB Flash 64-LFQFP | Renesas

The Renesas R5F10WLCAFB is a 16-bit RL78/L13 microcontroller built around the RL78 core running at 24MHz, integrating 32KB of flash memory and 64-pin LFQFP (10x10 mm) packaging. The device targets low-power embedded applications with on-chip segment LCD driver support and three selectable LCD voltage-generation methods (external resistor divider, capacitive split, and internal voltage boost). The RL78/L13 family implements the next-generation RL78 CPU core with the same instruction set as the 78K0R series, providing a migration path for legacy designs. A microcontroller (MCU) is a single-chip computer containing a CPU, memory (flash/RAM), and peripherals (timers, ADC, communication interfaces, LCD driver). The RL78 family is positioned in the 16-bit ultra-low-power MCU segment, hierarchically classified as: MCU -> microcontroller -> embedded processor -> semiconductor IC. The RL78/L13 specifically targets human-machine interface (HMI) applications where segment LCDs are used for display. Key features include 32KB flash, 2KB SRAM (typical for L13 family), 4-channel DMA, multiple timers, 10-bit A/D converter, on-chip segment LCD controller with 4 common x 36 segment (typical) capability, three LCD bias generation methods, and ultra-low-power operation with multiple standby modes (HALT, STOP, SNOOZE). The wide operating voltage range (1.6V to 5.5V typical for RL78/L13) supports battery-powered and energy-harvesting designs. The RL78 core uses a 3-stage pipeline Harvard architecture with single-cycle execution of most instructions, achieving 41.6ns minimum instruction cycle at 24MHz. Integrated peripherals include UART, I2C, CSI/SPI, and a multi-channel 10-bit ADC with up to 10 channels (per family datasheet). The on-chip debug function enables in-system programming and real-time debugging. Typical applications include home appliance LCD displays (washing machines, microwave ovens, refrigerators), measurement instruments with LCD readouts, battery-powered portable devices, industrial sensor modules with LCD indication, and metering equipment. The built-in segment LCD driver eliminates the need for an external LCD controller, reducing BOM cost and PCB area in HMI designs. When designing with this part, evaluate the LCD drive method that best matches the panel (external resistor divider is simplest; capacitive split reduces current; internal voltage boost eliminates external components). The SNOOZE mode allows peripheral operation during CPU STOP, enabling periodic sensor sampling while maintaining ultra-low system current consumption for battery applications.

R5F10WLGAFB

R5F10WLGAFB - RL78/L13 16-Bit 128KB Flash MCU | Renesas

The Renesas Electronics R5F10WLGAFB is a 16-bit RL78/L13 microcontroller featuring a 24 MHz CPU core, 128 KB of flash memory, and an integrated segment LCD driver, housed in a 64-pin LFQFP (10x10 mm) package. It is engineered for ultra-low-power operation in battery-driven and household appliances with LCD displays. An MCU (microcontroller unit) is a single-chip computer that integrates a CPU core, non-volatile memory (flash/ROM), volatile memory (RAM), and a rich set of peripheral interfaces such as timers, ADCs, communication controllers, and—on RL78/L13—a segment LCD driver. The RL78 family sits within Renesas's low-power 16-bit MCU portfolio, which is widely adopted in metering, white goods, healthcare devices, and other segment-LCD applications that demand years of battery life. The RL78/L13 supports three LCD driving voltage generation methods: external resistance division, capacitive split mode, and an internal voltage boost, enabling compatibility with a wide range of segment LCD panels. The device also integrates multiple low-power modes, a 12-bit A/D converter, and serial interfaces such as UART, I2C, and CSI, while achieving current consumption in the microamp range during LCD display operation. Architecturally, the RL78 core uses a 3-stage pipelined CISC-style design with banking of register pages, achieving high code density and very low active current (typically sub-mA/MHz). The integrated LCD controller can drive up to a large number of segments, offloading display refresh from the CPU and enabling deep-sleep LCD retention. Operating voltage spans 1.6 V to 5.5 V with on-chip regulators, supporting direct connection to 2x or 3x AA/AAA cells or a single lithium primary cell. Typical applications include home appliances with segment LCDs (washing machines, microwave ovens, air conditioners), utility meters (water/gas/electricity), medical measurement devices (blood pressure monitors, glucose meters), and industrial sensor readouts. The combination of segment LCD driver and ultra-low-power run mode positions the RL78/L13 as a strong fit for battery-powered human-machine interface designs. When designing with this device, evaluate the maximum segment count of your target panel against the LCD controller's SEG/COM allocation, and confirm that the 24 MHz system clock and 128 KB flash budget are sufficient for your application code. For metering or measurement applications requiring higher ADC precision or larger memory, consider migrating to the RL78/L1A or RL78/G14 family.

R5F10WLGAFB#30

R5F10WLGAFB#30 - 16-bit 24MHz RL78/L13 128KB MCU | Renesas

The Renesas R5F10WLGAFB#30 is a 16-bit RISC microcontroller from the RL78/L13 family, featuring 128 KB of flash memory, a 24 MHz CPU core, and integrated LCD segment driver, packaged in a 64-pin LFQFP (10x10 mm). 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.
