LPC1853JBD208E - 180MHz Cortex-M3 512KB MCU | NXP
部品番号: LPC1853JBD208E ✓ 生産中LPC1853JBD208E 概要
A microcontroller is a semiconductor containing a processor core, memory, peripherals, and interface controllers on one integrated circuit. The Cortex-M3 architecture uses a 32-bit instruction set and provides an efficient balance of performance, deterministic control, and low power consumption. Within the product hierarchy, this LPC1853 device is a 32-bit MCU, an embedded processor, and a configurable system-on-chip for real-time control and communication designs.
Key characteristics include an Arm Cortex-M3 processor running at 180 MHz, 512 KB of program flash, and support for an operating voltage of 3.3 V. The LPC1800 family is also described as supporting Ethernet, two high-speed USB interfaces, LCD connectivity, and EMC-oriented features, making it suitable for designs that combine human-interface or network functions with deterministic embedded control. The 208-pin LQFP provides access to a broad collection of parallel, serial, analog, and communication signals.
The large LQFP footprint provides ample routing access but requires careful PCB layout and thermal management. Because a microcontroller integrates high-speed digital circuitry and multiple I/O resources, clocking, power distribution, decoupling, and signal-return paths must be designed as an integrated system. Firmware should also be checked against the device’s clock configuration, memory map, peripheral availability, and pin multiplexing rather than relying only on the processor rating.
Typical uses include industrial control panels, USB-connected embedded equipment, Ethernet-capable terminal systems, LCD human-machine interfaces, data acquisition equipment, and connected industrial products. The 180 MHz Cortex-M3 core provides additional headroom for protocol processing, control loops, and graphical or communications workloads. Where the design uses USB, Ethernet, or an LCD, the external interface circuitry and software drivers should be validated against the selected LPC1853 variant and its exposed peripheral configuration.
A key design consideration is that the 512 KB flash and SRAM allocation, pin multiplexing, and peripheral availability must be reviewed against the final firmware and PCB requirements before layout release. For a 3.3 V design, validate all supply pins, ground connections, decoupling, and I/O levels against the manufacturer datasheet. The 28 mm by 28 mm LQFP also requires a land pattern with adequate thermal and copper support, while clock and high-speed interface routing demand short return paths and controlled impedance where applicable.
This product page combines the verified LPC1853JBD208E identity, package and memory characteristics with practical interface-selection guidance, verified family alternatives, and engineering considerations for evaluating the 208-pin Cortex-M3 MCU in a new embedded design.

主な用途
LPC1853JBD208E の用途: 6 件s: Industrial Control Panels, USB-Connected Embedded Equipment, Ethernet-Capable Terminal Systems, LCD Human-Machine Interfaces, Data Acquisition and Sensor Processing, Connected Consumer and Communication Products.
Industrial Control Panels
The LPC1853JBD208E fits industrial control panels that combine real-time logic, operator input, status indication, and multiple external interfaces. Its 180 MHz Arm Cortex-M3 core provides processing headroom for control tasks and communication protocols, while 512 KB of flash supports a substantial embedded application. The 208-pin LQFP exposes more signal options than a small-outline MCU and is useful when panel design includes display, communications, sensing, and actuator control. The tradeoff is a large 28 mm by 28 mm footprint requiring careful escape routing and adequate copper support. Firmware, peripheral assignments, and environmental limits should be validated against the manufacturer datasheet before production release.
おすすめ
USB-Connected Embedded Equipment
The LPC1853JBD208E is appropriate for USB-connected embedded equipment because the LPC1800 family supports two high-speed USB interfaces alongside its 180 MHz Cortex-M3 processor and 512 KB flash. A design can use one interface for a direct host or peripheral function and reserve the other for service, configuration, or device expansion. The MCU can coordinate USB enumeration, control data, diagnostics, and application firmware within one device. Careful planning is required for USB trace impedance, connector protection, ground return paths, and shared-bus firmware resources. The 208-pin package offers extensive pin assignment flexibility, although its larger footprint increases PCB complexity compared with a compact USB-capable MCU.
おすすめ
Ethernet-Capable Terminal Systems
The LPC1853JBD208E supports Ethernet-oriented embedded designs in the LPC1800 family, making it useful for network terminals, industrial gateways, and connected service equipment. Its 180 MHz Cortex-M3 core can divide time among network protocol handling, local control, diagnostics, and a user interface, while the 512 KB flash provides room for embedded TCP/IP stacks and application code. Ethernet PHY selection and isolation are external design considerations because the MCU requirement does not by itself define the complete network interface. Board partitioning, magnetics, clocking, impedance control, and surge protection require dedicated schematic and layout review. The large LQFP package also leaves more perimeter routing options than compact microcontroller packages.
おすすめ
LCD Human-Machine Interfaces
The LPC1853JBD208E is suited to LCD human-machine interfaces that combine a graphical display, touch or keypad input, status controls, and embedded communications. Its 180 MHz Cortex-M3 performance can support responsive display updates and local logic, while the 208-pin LQFP provides the interface count needed for parallel or serial display connections and control signals. Family-level LCD support means designers must still resolve the exact target-device LCD controller or display interface and its pin multiplexing in the manufacturer datasheet. The package’s high pin count simplifies routing of separate display and control buses but demands careful escape routing around a 28 mm square footprint. Display timing, contrast, backlight control, and EMC requirements should be verified during hardware bring-up.
おすすめ
Data Acquisition and Sensor Processing
The LPC1853JBD208E can serve as the central controller in a data-acquisition system that must sample sensors, apply filtering, record results, and communicate with a host. Its 180 MHz Cortex-M3 core supports concurrent control loops and protocol processing, and its 512 KB flash accommodates configuration, calibration tables, and application firmware. The 208-pin package provides a large selection of signal connections for sensors, switches, status indicators, and communication peripherals. Exact analog-function availability and pin assignments must be checked for the selected device because the processor and package alone do not define the complete measurement chain. Use short analog paths, defined grounding, suitable filtering, and careful separation between sensitive sensing and high-current switching sections.
おすすめ
Connected Consumer and Communication Products
The LPC1853JBD208E can support connected consumer and communication products that need local control alongside USB, Ethernet, or LCD functions. The Cortex-M3 core provides a compact real-time execution environment, while 512 KB of flash is suitable for many embedded protocols, user-interface logic, and configuration features. Its 208-pin LQFP is advantageous when the product requires numerous external controls and communication lines, although it is less area-efficient than a compact package. Software architecture should separate protocol handling, update logic, and safety-related control paths. Before schematic approval, verify the exact target-device peripheral set, temperature grade, power sequencing, and programming method to avoid designing around a family-level feature that differs by ordering code.

設計ノート
The 208-LQFP footprint has leads on all four sides and a 28 mm by 28 mm body. Assign escape routing before fixing the placement of external crystals, decoupling capacitors, and interface circuits. Follow the manufacturer package drawing for land dimensions, pin numbering, and solder-mask clearance. Keep the footprint free of accidental thermal-pad assumptions because this package has perimeter leads rather than an exposed pad.
Confirm every supply and ground pin in the LPC1853JBD208E pin table, then place the required local bypass capacitors at the associated device pins. The product is identified as a 3.3 V device, but voltage tolerances and sequencing conditions must come from the manufacturer datasheet. Separate quiet analog returns from switching or high-current return paths where the pin multiplexing permits it, and test supply ripple at the MCU pins under maximum processing and I/O activity.
Clock and communication signals should have short, continuous routes with nearby return paths. For Ethernet or USB implementations, use geometry appropriate to the required controlled impedance and provide a continuous reference plane without unnecessary voids. Keep crystal and high-speed clock traces away from switching nodes and noisy inductors. The large package offers routing flexibility, but only if pin multiplexing and escape planning are completed before signal assignment is frozen.
Do not treat the LPC1853, LPC1855, LPC1857, or LPC4357 names as interchangeable solely because several devices use a 208-LQFP package. Flash capacity, processor core, peripherals, pin multiplexing, boot behavior, and firmware startup code can differ. Before substitution, compare the manufacturer pin tables and memory maps, rebuild the boot and initialization paths where required, and run peripheral, communications, and boundary-condition tests on the revised board.
