LPC2368FET100 Overview
An ARM7 microcontroller is a member of the 16/32-bit RISC microcontroller family based on the ARM7TDMI-S core, sitting within the broader taxonomy of microcontrollers -> microprocessors -> embedded processors -> semiconductors. Compared with 8-bit 8051 or AVR devices, ARM7 cores offer substantially higher code density (Thumb mode), better interrupt handling, and rich on-chip peripherals for Ethernet and USB connectivity. Compared with later Cortex-M3 cores, ARM7TDMI-S lacks the deterministic interrupt latency and unified memory map of the Cortex-M series, but its mature toolchain (Keil, IAR, GCC) and large code base make it useful for legacy designs and field-deployed products.
Key features of the LPC2368FET100 include 72 MHz core clock, 512 kB flash for application code, 58 kB SRAM for data buffering, 100-pin TFBGA package (9x9 mm), Ethernet MAC for 10/100 Mbps networking, USB 2.0 full-speed Device/Host/OTG for USB connectivity, two CAN 2.0B channels for industrial networking, 8-channel 10-bit ADC, and 10-bit DAC for analog signal generation. Integrated peripherals reduce external component count and BOM cost while simplifying PCB layout.
The LPC2368FET100 is well suited for industrial gateways, building automation controllers, point-of-sale terminals, networked sensors, and USB peripherals. According to the NXP product page, the high peripheral count (Ethernet, USB, CAN, SD/MMC, multiple UARTs) eliminates the need for many external ICs, reducing both cost and board area. The 72 MHz ARM7 core delivers sufficient throughput for TCP/IP stacks and industrial communication protocols.
When designing with this device, ensure decoupling on all power pins and follow NXP AN10414 layout guidelines for TFBGA-100 routing. The integrated PHY is not included - an external Ethernet PHY such as the DP83848 is required for Ethernet applications. The USB DP/DM traces must be 90 ohm differential, length-matched, and routed without stubs.

Typical Applications
LPC2368FET100 is suitable for 6 applications: Industrial Ethernet Gateways, USB Peripherals and HID Devices, Building Automation Controllers, Point-of-Sale (POS) Terminals, CAN-Based Automotive Body Controllers, Data Loggers with SD Card Storage.
Industrial Ethernet Gateways
The LPC2368FET100's integrated 10/100 Ethernet MAC and 512 kB flash make it ideal for industrial Ethernet gateway applications bridging Modbus TCP, EtherNet/IP, or PROFINET fieldbus networks with cloud or supervisory systems. Combined with 58 kB SRAM for TCP/IP socket buffering and the 72 MHz ARM7 core sufficient to run lwIP or uIP stacks, the part eliminates the need for an external protocol translation ASIC. Two CAN 2.0B channels allow simultaneous CAN-to-Ethernet bridging for industrial automation. An external Ethernet PHY such as the DP83848 or KSZ8041 pairs with the on-chip MAC for physical layer MII/RMII connectivity, while the integrated DMA controller offloads packet buffering from the CPU.
Recommended
USB Peripherals and HID Devices
The LPC2368FET100's integrated USB 2.0 Device/Host/OTG controller with on-chip transceiver makes it ideal for USB peripherals such as USB-to-UART bridges, USB mass-storage interfaces, and USB-HID devices. The 512 kB flash accommodates USB class drivers (CDC, HID, MSC) alongside application code, while the 58 kB SRAM provides buffer space for endpoint transactions. Full-speed 12 Mbps operation is supported natively without external PHY, and minimal external components (15 kohm pull-down on D+, decoupling) are required. For USB host applications, the part can drive USB flash drives, keyboards, and mice, making it suitable for industrial operator panels and POS terminals.
Recommended
Building Automation Controllers
The LPC2368FET100's combination of Ethernet, dual CAN, multiple UARTs, and 10-bit ADC/DAC makes it well suited for building automation controllers managing HVAC, lighting, and access control subsystems. The Ethernet MAC enables BACnet/IP or Modbus TCP communication with supervisory BMS software, while the two CAN channels support CANopen or DeviceNet sensor networks. The four UARTs connect to RS-485 subnets for legacy HVAC equipment, and the 8-channel 10-bit ADC reads analog temperature, humidity, and pressure sensors. The 72 MHz ARM7 core runs the building automation protocol stack with cycle times under 50 ms, and the RTC provides time-of-day scheduling.
Recommended
Point-of-Sale (POS) Terminals
The LPC2368FET100's peripheral richness makes it suitable for compact POS terminals integrating barcode scanner interface (UART), receipt printer (SSP/SPI), customer display (I2C), magnetic-stripe reader (UART), Ethernet for payment gateway connectivity, and USB for keyboard or cash drawer. The 512 kB flash accommodates the POS application firmware, encryption libraries, and payment protocol stacks, while the 58 kB SRAM handles transaction buffering. The integrated 10-bit DAC can drive an audio prompt speaker for transaction feedback, and the RTC timestamps transactions for end-of-day reporting.
Recommended
CAN-Based Automotive Body Controllers
The LPC2368FET100's dual CAN 2.0B channels and 10-bit ADC suit it for non-safety automotive body controllers managing comfort features such as seat adjustment, mirror control, and ambient lighting. The two CAN interfaces connect to the vehicle's body CAN bus for receiving switch inputs and broadcasting actuator commands, while the ADC reads potentiometer positions for analog controls. The PWM blocks drive LED dimming for ambient lighting, and the UARTs interface with diagnostic tools. Operating temperature range of -40 C to +85 C covers cabin environments. Note that AEC-Q100 qualification is not available for this part - for safety-critical applications use an AEC-Q100 qualified MCU.
Recommended
Data Loggers with SD Card Storage
The LPC2368FET100's SD/MMC interface combined with 10-bit ADC and RTC makes it ideal for portable data loggers recording sensor data to SD cards. The SD/MMC controller supports SDSC/SDHC cards up to 32 GB for long-term data storage, while the DMA controller handles block transfers without CPU intervention. The 8-channel ADC reads multi-sensor inputs (temperature, voltage, current, pressure), and the 72 MHz ARM7 core runs FAT file system and timestamp formatting in real time. Battery operation is supported by the device's low active-power consumption, and the RTC maintains timestamp accuracy across power cycles.

Key Differentiators
- Largest flash in LPC236x TFBGA-100 family (vs LPC2364FET100)
- Full 58 kB SRAM for TCP/IP buffering (vs LPC2364FET100)
- Same TFBGA-100 footprint as entire LPC2364/65/66/67/68 family (vs LPC1768 (Cortex-M3 successor))
Design Notes
The 100-TFBGA package requires via-in-pad PCB design to route signals out from the inner balls. Use 0.4 mm via diameter with 0.8 mm ball pitch, filled and capped vias per IPC-7093. Place decoupling capacitors (100 nF + 10 uF) within 2 mm of each power pin pair. Maintain continuous ground plane beneath the BGA for thermal dissipation and signal integrity.
The LPC2368FET100 has multiple power pins: 3.3V for digital core, 3.3V for analog ADC/DAC, and 3.3V for I/O. Each domain should have its own decoupling network. The analog supply (VddA) must be filtered with a ferrite bead or LC filter from the digital 3.3V rail to minimize ADC noise. Total active current at 72 MHz is approximately 50 mA plus peripheral contribution - budget for a 200 mA LDO or switching regulator.
The integrated Ethernet MAC requires an external PHY - connecting the MII/RMII signals without a PHY will not bring up the link. The USB DP/DM traces must be 90 ohm differential, length-matched within 150 mil, and routed over a continuous ground plane without stubs. The CAN bus requires a transceiver such as TJA1050 - the on-chip CAN controller does not include physical layer drivers.
Estimated: at 72 MHz core clock with all peripherals active, the LPC2368FET100 dissipates approximately 200 mW. The TFBGA-100 package has a theta_JA of approximately 35 C/W (4-layer PCB with thermal vias), giving a junction temperature rise of 7 C above ambient - well within the 85 C operating range for typical industrial environments. For high-ambient (>70 C) applications, add thermal vias under the BGA and increase copper pour area.
Compliance Information
RoHS and REACH compliant per NXP product page. Not AEC-Q100 qualified - do not use for automotive safety-critical applications.
