R5F110NJALA#U0 - 16-Bit 24MHz 256KB LCD MCU | Renesas
料号： R5F110NJALA#U0 ✓ 量产中R5F110NJALA#U0 概述
RL78/L1C microcontrollers are low-power 16-bit microcontrollers within Renesas' RL78 family. They are used where a compact controller must combine local display control, data acquisition, communication, and low standby power in a single device. The R5F110NJALA#U0 targets instruments that present information on a segment LCD while also exchanging data with a host or peripheral.
Key features include a 24 MHz operating frequency, 256 KB of flash memory organized as 256K x 8, a built-in segment LCD driver, and USB 2.0 support. The LCD section provides three voltage-generation approaches: external resistance division, capacitive split, and internal voltage boost, allowing the display interface to match different panel requirements. The -40 °C to +85 °C temperature range supports industrial and medical equipment environments.
The device belongs to the RL78/L1C family of high-function LCD microcontrollers. Its flash capacity supports larger firmware than small segment-display controllers, while the 16-bit architecture provides efficient handling of display data, sensor values, and USB communication tasks. The 85-VFLGA package is intended for compact, high-density assemblies where the board area around the LCD and connector is limited.
Typical applications include blood-pressure monitors, healthcare monitoring equipment, sensor modules, panel controls, portable measurement instruments, and USB-connected human-interface devices. The combination of a segment LCD controller and USB 2.0 is particularly useful where a compact product needs local feedback without a separate display driver.
When laying out the board, preserve the manufacturer's recommended decoupling and exposed-pad or thermal-via arrangement for the 85-VFLGA package. Confirm LCD bias, segment count, and panel voltage-generation requirements against the device data sheet before finalizing the display circuitry.

典型应用
R5F110NJALA#U0 适用于 6 应用s: Healthcare Monitor with Segment LCD, USB-Connected Sensor Module, Rapid-Charging Battery Instrument, Industrial Panel Controller, Portable Measurement Instrument, Blood-Pressure Monitor Controller.
Healthcare Monitor with Segment LCD
The R5F110NJALA#U0 fits compact healthcare monitors that combine a local segment display with USB connectivity. Its 24 MHz 16-bit core handles display updates and sensor control, while 256 KB of flash provides room for measurement algorithms, calibration data, and interface code. The integrated segment LCD driver and three selectable voltage-generation methods help accommodate different panel arrangements. The -40 °C to +85 °C range suits controlled medical-equipment environments, although the finished product must still meet its applicable safety and regulatory requirements.
推荐
USB-Connected Sensor Module
The R5F110NJALA#U0 is suitable for a sensor module that exposes measurements through USB while presenting status on an integrated segment LCD. The 256 KB flash capacity supports protocol stacks, calibration tables, and sensor-conditioning routines, while the 24 MHz CPU rate provides useful margin for polling and filtering. USB 2.0 integration reduces the need for a separate interface controller, and the three LCD drive-voltage options allow the display design to be adapted to different glass modules.
推荐
Rapid-Charging Battery Instrument
The R5F110NJALA#U0 fits portable instruments where the MCU must coordinate a rapid-charging function, a local LCD, and host communication. Its 24 MHz 16-bit RL78/L1C core can supervise charging-state logic and user-interface events, and 256 KB of flash holds firmware for the charging profile and display calibration. The 85-VFLGA 7 x 7 mm package helps preserve board area in handheld products. Validate the charging profile, thermal limits, and USB enumeration behavior against the current Renesas documentation.
推荐
Industrial Panel Controller
The R5F110NJALA#U0 works well in a compact industrial panel controller that needs a segment LCD, sensor inputs, and a wired host link. Its 256 KB flash accommodates panel configuration, diagnostic logging, and communication firmware, while the integrated LCD driver reduces the external component count. The -40 °C to +85 °C operating range covers many industrial environments, and the 7 x 7 mm 85-VFLGA package supports dense control boards. Confirm EMC susceptibility, brownout behavior, and display timing in the final system design.
推荐
Portable Measurement Instrument
The R5F110NJALA#U0 is appropriate for portable measurement instruments that need a readable local display, data logging, and USB transfer. The 24 MHz 16-bit core supports acquisition sequencing and display updates, and 256 KB of flash can retain instrument firmware and configuration data. USB 2.0 enables a direct connection to a computer or service interface without a separate communications IC. Power budgeting, LCD contrast over temperature, and connector ESD protection should be reviewed alongside the controller selection.
推荐
Blood-Pressure Monitor Controller
The R5F110NJALA#U0 fits a compact blood-pressure or wellness monitor that combines sensor control, numeric or segment-display feedback, and USB connectivity. Renesas specifically positions the RL78/L1C device for healthcare devices, and its 256 KB flash supports measurement routines, interface protocols, and stored settings. The integrated segment LCD controller reduces the display subsystem footprint, while rapid-charging support can simplify power-management integration in rechargeable models. Confirm electrode-drive timing, safety isolation, and calibration architecture for each monitor design.

设计说明
Use the Renesas 85-VFLGA land pattern and pin-assignment table rather than a generic 85-pin footprint. Place the required input and output capacitors close to their designated pins, route USB differential pairs as a short pair with continuous reference, and keep the LCD segment and bias routing away from the USB pair. Confirm exposed-pad or thermal-via requirements against the current package drawing before releasing the PCB.
Design the USB and LCD power rails around the operating voltage range, USB bus states, and rapid-charging operating mode specified in the current device documentation. Include the required USB protection and filtering, and confirm brownout behavior during source negotiation or charger transitions. Separate sensitive LCD bias routing from charger-related switching paths to reduce display noise and prevent unstable display thresholds.
Do not assume that matching CPU speed, flash size, and package dimensions proves a drop-in substitution. Before replacing the R5F110NJALA#U0 with a family member, compare the complete pin list, alternate-function mapping, LCD drive capability, USB behavior, oscillator requirements, programming interface, and power-sequencing conditions. Update firmware and validation tests for any peripheral, interrupt-vector, or timing differences identified during that review.
Although the rated ambient range is -40 °C to +85 °C, the internal junction temperature depends on local dissipation, board construction, enclosure ventilation, and adjacent heat sources. Place the controller according to the package thermal guidance and provide copper and vias where the package drawing calls for them. Evaluate worst-case supply voltage and peripheral activity rather than assuming that a low-power MCU cannot create localized temperature rise.
