R5F110NJGLA#U0 - 24MHz 256KB RL78/L1C MCU | Renesas
MPN: R5F110NJGLA#U0 ✓ نشطR5F110NJGLA#U0 نظرة عامة
An RL78 microcontroller is a low-power embedded controller based on the Renesas RL78 architecture. Within the semiconductor hierarchy, this product is a 16-bit microcontroller, embedded processor, and system-on-chip designed to combine program memory, RAM, communications peripherals, timing functions, and analog or display interfaces in one package. The RL78/L1C family targets compact, low-energy products that require USB connectivity and human-machine-interface capability.
Key features include 24 MHz maximum operating frequency, 256 KB of flash for firmware storage, 16 KB of SRAM, and USB 2.0 support. The integrated segment LCD driver can operate with external resistor-divider, capacitive-split, or internal voltage-boost approaches. A maximum operating temperature of +105°C supports use in electrically demanding industrial, healthcare, and sensor-module environments when the complete system design satisfies the device's operating limits.
The R5F110NJGLA#U0 combines a 16-bit CPU, 256K × 8 flash organization, 16 KB of RAM, USB 2.0, and an LCD controller in an 85-VFLGA package. Its flash capacity permits larger application programs, display tables, and USB communication stacks than smaller RL78 variants. The 24 MHz clock also provides additional processing headroom for protocol handling, sensor sampling, debouncing, and user-interface updates in compact embedded products.
Typical applications include USB-connected sensor modules, healthcare monitoring equipment, segmented LCD instruments, portable measurement products, and industrial interface panels. Its USB 2.0 function is particularly useful for configuration, data logging, firmware upgrades, and communication with a host computer. The segment LCD driver reduces the component count in display-centric products while leaving the MCU available for measurement and control functions.
PCB design should provide a stable supply, compliant USB routing, decoupling close to the power pins, and controlled escape routing from the 85-VFLGA package. USB differential traces should be length-matched and routed as a continuous pair over a continuous reference plane. Firmware design should account for USB suspend behavior, LCD update timing, and the device-specific pin multiplexing required by the 85-ball land pattern.
This product page combines manufacturer positioning, exact orderable-part data, application guidance, comparison fields, and design-focused implementation notes. The structured information helps engineers evaluate the R5F110NJGLA#U0 for USB-enabled LCD products, assess package and memory requirements, and plan a deliberate transition from prototype hardware to production assembly.

التطبيقات النموذجية
R5F110NJGLA#U0 مناسب لـ 6 التطبيقs: USB Sensor Module, Healthcare Monitoring Device, Segmented LCD Instrument Panel, Industrial Data Logger, Portable Measurement Product, Human-Machine Interface.
USB Sensor Module
The R5F110NJGLA#U0 fits a USB-connected sensor module because it combines a 24 MHz RL78/L1C core, USB 2.0, 256 KB of flash, and 16 KB of RAM in one 85-VFLGA device. Firmware can sample sensors, format measurements, expose a USB interface, and maintain configuration parameters without requiring a separate USB controller. The 256 KB flash provides room for protocol stacks and data tables. When adding a local segmented display, the integrated segment LCD driver reduces external controller demand, although the selected glass must support the required segment and common-segment arrangement.
موصى به
Healthcare Monitoring Device
The R5F110NJGLA#U0 is appropriate for compact healthcare monitoring products that need local measurement control and USB data exchange. Its 24 MHz processor supports acquisition logic, filtering, event handling, and communication firmware, while 256 KB of flash accommodates larger algorithms and 16 KB of RAM supports working buffers. The segment LCD controller can present measurements or status information locally. For a device intended for clinical environments, engineers should separately validate applicable product, safety, and environmental requirements rather than treating the microcontroller qualification as complete system compliance.
موصى به
Segmented LCD Instrument Panel
The R5F110NJGLA#U0 suits compact instruments with a segmented LCD because it integrates the display controller with a 24 MHz 16-bit core and 256 KB of flash. The LCD driver supports external resistance division, capacitive split, and internal voltage boost, allowing the display architecture to be selected for the actual panel. This integration can reduce controller count while preserving CPU capacity for measurements, keypad processing, calibration, and USB diagnostics. Before layout release, verify segment count, common configuration, glass voltage limits, bias timing, and every multiplexed ball assignment.
موصى به
Industrial Data Logger
The R5F110NJGLA#U0 can serve as the control and communications MCU in an industrial data logger that combines sensors, local storage, and USB export. Its 256 KB flash provides useful program and log-index capacity, while 16 KB of RAM supports buffering and protocol processing. The USB 2.0 interface enables configuration, log transfer, and firmware maintenance from a host system. Its stated +105°C maximum temperature supports applications with elevated internal temperatures, but the complete logger still needs appropriate storage media, power protection, enclosure thermal design, and verified industrial operating requirements.
موصى به
Portable Measurement Product
The R5F110NJGLA#U0 is well matched to portable measurement products that combine an LCD, USB connectivity, and moderate embedded processing. The 24 MHz core can manage acquisition timing, calculations, control logic, and display updates, while 16 KB of RAM provides a practical working area. USB 2.0 allows a host to charge, configure, collect results, or update firmware when the product includes the required power-management and battery-charging circuitry. Designers should assess quiescent behavior, active current, analog front-end requirements, and display performance across the intended battery-voltage range.
موصى به
Human-Machine Interface
The R5F110NJGLA#U0 supports compact human-machine interfaces that need a local segmented display and an external host connection. The integrated segment LCD controller handles display excitation while the 24 MHz CPU manages input scanning, status logic, and USB communication. Its 256 KB flash is useful for interface tables, localization data, diagnostic commands, and protocol functions. The 85-VFLGA package can support dense layouts, but its fine-pitch ball array requires careful PCB fanout, assembly-profile checks, and inspection planning to achieve reliable production yields.

ملاحظات التصميم
Route the USB D+ and D- conductors as a closely coupled differential pair over a continuous ground reference. Avoid splitting the reference plane beneath the pair, minimize stubs, and apply the USB impedance target specified by the complete board stack-up. Place USB protection and common-mode components close to the connector, while keeping high-current or switching-regulator nodes away from the communication path.
The 85-VFLGA land pattern requires dense escape routing and careful assembly planning. Follow the manufacturer land-pattern dimensions and solder-mask recommendations exactly, verify component placement orientation, and plan X-ray or optical inspection for hidden joints. Keep decoupling capacitors close to their assigned supply balls with short ground returns, and route high-current loops independently from LCD and USB signals.
Do not infer the complete pin function from the package name alone; several 85-VFLGA balls can have configurable peripheral assignments. Review the manufacturer ball table for the selected configuration, USB functions, LCD outputs, programming signals, resets, clocks, and analog functions. Also verify that the USB power path meets the selected host or device role and that the LCD drive method is compatible with the glass characteristics.
Build the supply network around the manufacturer operating-voltage and decoupling recommendations. Estimated: power dissipation in the MCU is load-dependent and cannot be derived from the product snippets without the selected clock, peripherals, and junction-temperature data. Validate the design at minimum and maximum supply voltage, during USB suspend or disconnect states, and with the LCD and USB interfaces active concurrently.
