LPC2368FBD100K - 72MHz ARM7 MCU with Ethernet | NXP
MPN: LPC2368FBD100K ✗ Son Kullanım ZamanıLPC2368FBD100K Genel Bakış
An ARM7 microcontroller is a 32-bit embedded processor that combines a CPU core, memory, interrupt handling, and programmable peripherals in one integrated circuit. The LPC2300 family belongs to the broader embedded-microcontroller and semiconductor hierarchy. In system terms, the LPC2368FBD100K can serve as the central real-time controller between sensors, communications equipment, human-interface circuits, and external storage. Its integration reduces component count while preserving dedicated hardware for Ethernet, USB, CAN, serial data, and analog measurement.
The primary architectural advantage is the 72 MHz ARM7TDMI-S core paired with the LPC2300 accelerator and memory organization. The device provides 512 KB of flash for firmware and 58 KB of SRAM for working data, while a 128-bit-wide memory interface supports the CPU's maximum clock rate. An Ethernet MAC supports network-connected equipment, while USB Device, Host, and OTG operation broadens its role in host and peripheral designs. Two CAN channels suit industrial communication, and the DMA controller moves data with less CPU intervention.
The integrated serial resources support several embedded architectures. Four UARTs can connect external sensors, service consoles, or industrial equipment; three SSP/SPI interfaces support fast serial peripherals; three I2C buses suit low-speed controllers and sensors; and I2S provides a dedicated path for digital audio data. The eight-channel 10-bit ADC handles analog inputs, the 10-bit DAC generates analog output, and two PWM blocks support timing, dimming, or motor-control functions. A 10-bit ADC is appropriate for supervisory measurement rather than precision instrumentation with substantially higher resolution requirements.
Typical applications include industrial Ethernet gateways, USB-to-serial equipment, CAN-connected control systems, SD/MMC data loggers, audio-capable embedded controllers, and multi-interface test equipment. The Ethernet MAC, USB controller, and CAN channels allow the MCU to bridge communication technologies. The ADC and DAC support supervisory control loops, while SD/MMC connectivity supports removable or nonvolatile data storage. Firmware can also use the ISP and IAP capabilities associated with the LPC2364/65/66/67/68 family for in-system programming and application update workflows.
A successful design must account for the 100-pin footprint, all peripheral pin multiplexing, power-supply sequencing, clock configuration, and the demands placed by simultaneous Ethernet, USB, CAN, and memory activity. The LQFP package provides accessible leads for assembly and inspection, but the high pin count requires careful fanout and signal-integrity planning. Firmware should configure each peripheral only after resolving its alternate-function pins and should verify the resulting pin muxing against the manufacturer pin-description table.
This page consolidates the exact LPC2368FBD100K identity, verified memory and interface specifications, lifecycle information, sourcing guidance, same-family alternatives, and practical integration considerations. It is intended to help engineers determine whether the original LPC2300 device remains appropriate for an existing 100-LQFP design and how to evaluate a replacement without overlooking changes in memory, peripherals, pin multiplexing, or firmware requirements.

Tipik Uygulamalar
LPC2368FBD100K için uygundur 6 uygulamas: Industrial Ethernet Gateway, USB-to-Serial Communication Equipment, CAN-Connected Industrial Control, SD/MMC Data Logger, Embedded Audio Control System, Multifunction Embedded Controller.
Industrial Ethernet Gateway
The LPC2368FBD100K fits an industrial Ethernet gateway because its 72 MHz ARM7TDMI-S core can manage protocol processing while the integrated Ethernet MAC handles network traffic. Its 512 KB of flash accommodates gateway firmware, and 58 KB of SRAM supports protocol state, packet buffers, and control logic. Four UARTs and three I2C buses can connect local sensors, while SD/MMC storage can retain logs or configuration data. The principal design consideration is assigning Ethernet, DMA, and serial functions to the correct multiplexed pins in the 100-lead LQFP footprint. Firmware should use the manufacturer pin-description table and exercise the gateway with sustained network traffic to validate buffer handling.
Önerilen
USB-to-Serial Communication Equipment
The LPC2368FBD100K is suitable for USB-to-serial equipment because it combines USB Device, Host, or OTG capability with four UARTs in a single 72 MHz microcontroller. A design can expose USB connectivity while UART channels serve sensors, service ports, or downstream processors. The 58 KB of SRAM provides useful working space for USB buffers, command processing, and data routing, while 512 KB of flash supports protocol conversion and configuration firmware. USB signal routing, impedance-controlled traces, power supervision, and shared peripheral-pin assignments should be reviewed before layout release. Testing should include enumeration, suspend and resume behavior, sustained data transfer, and simultaneous UART traffic.
Önerilen
CAN-Connected Industrial Control
The LPC2368FBD100K supports CAN-connected control systems through two dedicated CAN channels and a 72 MHz ARM7 core. Those channels can coordinate distributed equipment, while three SSP/SPI interfaces, three I2C buses, and four UARTs provide paths to sensors, actuators, and service equipment. The 512 KB flash and 58 KB SRAM are suitable for protocol stacks, control logic, diagnostics, and data buffering. Designers should define termination, protection, and transceiver requirements around the MCU pins rather than driving a CAN bus directly. Firmware validation should include bus-off recovery, error counters, interrupt latency, and operation under simultaneous CAN traffic and external serial activity.
Önerilen
SD/MMC Data Logger
The LPC2368FBD100K can serve as an SD/MMC data logger because it combines dedicated storage-interface capability with ample embedded flash and SRAM for buffering. The 72 MHz processor can format and manage files, sample external sensors, and store records while the ADC handles analog inputs. Three I2C buses suit low-speed environmental or status sensors, and four UARTs can receive auxiliary sensor streams. The design must account for card-detect and write-protection signals, bus timing, and the power demands of removable storage. Firmware should use wear-aware write practices and test uninterrupted logging across card insertion, removal, and power-loss conditions to reduce the risk of corrupted records.
Önerilen
Embedded Audio Control System
The LPC2368FBD100K is appropriate for embedded audio-control systems that need digital-audio transport and supervisory rather than high-resolution conversion. Its I2S interface provides a dedicated digital-audio path, while the 10-bit DAC and eight-channel 10-bit ADC support control signals, monitoring, and basic analog output. Four UARTs and three SSP/SPI interfaces allow connection to amplifiers, codecs, configuration modules, or synchronized sensors. The 72 MHz core and 58 KB SRAM can support real-time buffering, though audio-clock and DMA behavior must be validated against the required sample rate. Board design should keep I2S timing clean, provide suitable analog support circuitry, and verify that shared pins do not conflict with audio or control functions.
Önerilen
Multifunction Embedded Controller
The LPC2368FBD100K is well matched to multifunction embedded controllers that must combine communications, measurement, storage, and timing. One 72 MHz MCU provides Ethernet, USB, two CAN channels, four UARTs, three SSP/SPI buses, three I2C buses, SD/MMC, DMA, PWM, and 10-bit conversion functions. This integration allows a compact board to replace several separate interface ICs while retaining a single firmware event model. The principal trade-off is pin multiplexing: enabling many peripherals simultaneously can create conflicts in the 100-lead LQFP. Build the schematic around a resource-allocation table, validate every alternate-function assignment, and reserve boot, debug, clock, and reset functions before assigning the remaining pins.

Tasarım Notları
Create the board footprint from the manufacturer's 100-lead LQFP drawing rather than relying only on the generic 14 x 14 mm package name. Confirm lead pitch, exposed thermal area, courtyard limits, pin-1 orientation, pad numbering, and solder-mask design against the NXP package drawing. LPC2368 alternate functions can occupy many of the same pins, so reserve the power, ground, reset, clock, boot, and JTAG assignments before laying out Ethernet, USB, CAN, or high-speed serial signals.
Plan the power tree around the processor core and I/O currents in the LPC2364/65/66/67/68 datasheet rather than estimating from the 72 MHz clock rate alone. Provide local high-frequency and bulk decoupling at every supply group, observe sequencing and voltage limits, and keep switching or Ethernet-supply return currents away from sensitive analog returns. Estimated: if the final worst-case supply dissipation is calculated as voltage drop times total current, compare that result with the package and PCB thermal limits rather than using a generic junction-temperature allowance.
Review every enabled peripheral for pin-multiplexing conflicts and assign its clock, data, and control functions together. USB and Ethernet require deliberate topology and return-path planning, while CAN requires a correctly terminated physical bus and suitable transceiver protection. Place the oscillator, PLL supply filtering, decoupling, and programming or debug access according to the reference layout in the manufacturer datasheet. Validate signal timing at the target 72 MHz operating point with the intended external components and PCB stack-up.
A substitute from the LPC236x family is not automatically equivalent even when it uses the same 100-LQFP outline. Compare flash, SRAM, Ethernet MAC, CAN count, USB mode, ADC channels, DAC, PWM, pin multiplexing, clocking, and peripheral addressing in the NXP datasheet. The LPC1768 is a redesign candidate rather than a transparent replacement, and the LPC2378 and LPC2388 use 144-lead packages. Preserve the original firmware and startup configuration when testing any drop-in candidate.
