LPC2368FBD100 - ARM7 72MHz 512KB Flash MCU | NXP
MPN： LPC2368FBD100 ✓ 啟用中LPC2368FBD100 概覽
An ARM7 microcontroller is a 32-bit RISC processor core that executes both the 32-bit ARM and the 16-bit Thumb instruction set, allowing code-density and performance trade-offs. The ARM7TDMI-S variant adds a hardware multiplier and embedded ICE debug logic. Within NXP's portfolio, the LPC2300 family sits at the top of the legacy LPC2000 ARM7 line, ahead of the smaller LPC2100 and LPC2200 series, and is itself succeeded by the Cortex-M3 based LPC1700 family. Peripherals are tightly integrated to minimize external components in industrial Ethernet, USB, and CAN nodes. The device operates from a single 3.0 V to 3.6 V supply, with I/O tolerant to 5 V, and is housed in a 100-pin LQFP (14 x 14 mm) package suitable for cost-sensitive 4-layer PCB layouts.
Key features include 72 MHz maximum CPU clock with on-chip PLL, 32 kB SRAM usable as battery-backed retention, vectored interrupt controller for deterministic real-time response, and ISP/IAP in-application programming via UART or CAN. The Ethernet MAC supports 10/100 Mbps MII/RMII with full-duplex operation, while the USB 2.0 controller supports device, host, and OTG roles. The ADC delivers 400 ksps across 8 channels at 10-bit resolution, and the DAC is a 10-bit rail-to-rail converter suitable for waveform generation.
Typical applications include industrial Ethernet gateways, building automation controllers, USB peripherals and embedded hosts, CAN-based automotive body modules, point-of-sale terminals, and small-scale motor-control boards. Designers choose the LPC2368FBD100 when ARM7 firmware, a wide peripheral mix, and 512 kB of on-chip flash are required without an external memory bus.
When designing with this device, ensure the 3.3 V analog supply (V3A) is decoupled with at least 100 nF plus a 10 uF bulk, and isolate it from the digital 3.3 V plane to avoid ADC/DAC noise coupling. The VBAT domain supports RTC backup and 32 kB of retained SRAM; route a small lithium cell or supercap there to preserve RTC time across power cycles.

典型應用
LPC2368FBD100 適用於 7 應用s: Industrial Ethernet Gateway / PLC, USB Embedded Host / Device Controller, Building Automation / HVAC Controller, Automotive Body / CAN Gateway Module, Point-of-Sale (POS) Terminal, Small-Scale Motor Control / BLDC Driver, Data Acquisition / Industrial Sensor Hub.
Industrial Ethernet Gateway / PLC
The LPC2368FBD100's on-chip 10/100 Ethernet MAC and full-duplex MII/RMII make it an ideal main controller for Modbus TCP, EtherNet/IP, or PROFINET gateways, replacing external MAC chips. Its ARM7TDMI-S at 72 MHz delivers sufficient headroom for TCP/IP stacks while two CAN 2.0B channels allow bridging to legacy industrial buses. Placed on a 4-layer board with a 3.3 V analog island, it gives deterministic performance with 32 kB of battery-backed SRAM retaining configuration across power loss.
推薦
USB Embedded Host / Device Controller
The LPC2368FBD100's integrated USB 2.0 controller supports Device, Host, and OTG roles, allowing firmware-driven USB stacks for mass-storage hosts, HID peripherals, or CDC devices without an external interface IC. The on-chip 512 kB flash accommodates USB class drivers and FAT32 file systems, while 58 kB SRAM buffers bulk transfers. Compared to discrete USB solutions it removes BOM cost and PCB area, especially when paired with the on-chip DMA controller to offload endpoint handling from the CPU.
推薦
Building Automation / HVAC Controller
Building automation controllers need a wide peripheral mix on a single chip - the LPC2368FBD100 provides 4 UARTs for RS-485 trunks, 3 I2C buses for sensor and EEPROM access, an SD/MMC interface for local data logging, and an 8-channel 10-bit ADC for analog temperature and humidity inputs. The 32 kB battery-backed SRAM preserves scheduler state across power cycles, while the RTC with VBAT domain keeps accurate time-stamping. Its 3.0-3.6 V supply with 5 V tolerant I/O allows direct connection to industrial 24 V conditioned sensor lines.
推薦
Automotive Body / CAN Gateway Module
Automotive body controllers and CAN gateways benefit from the LPC2368FBD100's dual CAN 2.0B channels and 72 MHz ARM7 core running OBD-II or CANopen stacks. Although the part is not AEC-Q100 qualified (it is industrial grade -40 to +85 C), it remains widely used in non-safety automotive nodes such as infotainment auxiliary MCUs and diagnostic bridges. The Ethernet MAC plus dual CAN combination is uniquely strong for telematics control units forwarding CAN traffic over automotive Ethernet.
推薦
Point-of-Sale (POS) Terminal
POS terminals need USB, Ethernet, multiple serial peripherals, and secure firmware storage - the LPC2368FBD100's 512 kB flash supports encrypted boot loaders, its 58 kB SRAM handles transaction buffers, and its on-chip USB OTG allows direct connection to printers or PIN pads. Compared to Cortex-M0 alternatives, the 72 MHz ARM7 delivers faster DES/AES for legacy payment flows. The LQFP-100 package and 5 V-tolerant GPIO simplify mixed-voltage peripheral boards.
推薦
Small-Scale Motor Control / BLDC Driver
The LPC2368FBD100 includes 2 dedicated motor-control PWM blocks with quadrature encoder input, suited to small BLDC or stepper control up to a few hundred watts. The 10-bit ADC samples back-EMF and current sense, while the 10-bit DAC provides a programmable reference. ARM7 latency at 72 MHz is fast enough for 20 kHz PWM loops with PI control, and the dual CAN channels expose drive status to a vehicle or machine network.
推薦
Data Acquisition / Industrial Sensor Hub
Industrial sensor hubs route analog inputs to Ethernet or CAN backbones - the LPC2368FBD100's 8-channel 10-bit ADC at 400 ksps handles multi-sensor scanning, while its on-chip Ethernet MAC streams the data to a SCADA server. With 58 kB SRAM it can buffer 4 kSamples between transmissions. The 5 V tolerant GPIO accepts legacy 4-20 mA loop signals through external resistor networks without additional level shifters, simplifying the analog front end.

主要差異化特點
- Highest flash density in the LPC236x LQFP-100 family (對比LPC2366FBD100)
- Largest SRAM with battery backup (對比LPC2367FBD100)
- Integrated Ethernet MAC plus USB OTG plus dual CAN in one chip (對比STM32F107VBT6 (closest cross-brand competitor))
設計說明
The LPC2368FBD100 has separate digital (Vdd) and analog (V3A/Vdda) supply domains. Per the NXP datasheet, decouple each Vdd pin with 100 nF X7R plus a shared 10 uF bulk, and isolate V3A with a ferrite from Vdd to minimize ADC and DAC noise. VBAT should be tied to a small lithium cell or supercap through a 1 kohm isolation resistor to retain the RTC and 32 kB backup SRAM across power loss.
The LQFP-100 (14 x 14 mm, 0.5 mm pitch) package benefits from a 4-layer PCB with a continuous ground plane on layer 2. Keep Ethernet MAC traces (P1[0..17]) short and length-matched within 25 mm to the PHY (KSZ8041 etc.) to avoid MII timing violations. Place the 12 MHz crystal within 5 mm of XTAL1/XTAL2 with a guarded ground ring to suppress EMI from the 72 MHz PLL output.
Do NOT assume the LPC1768FBD100 is a drop-in replacement - it is a Cortex-M3 part with different pin mapping (notably pin 13). ISP/IAP via UART0 requires the external pins P0[14] and P0[15] to be configured correctly during reset; if the BOOT pins are mis-pulled, firmware can lock itself out and require JTAG recovery. The USB_VBUS pin (P0[31]) must be connected even if USB is unused, otherwise VBUS sensing fails and the USB block cannot enter suspend correctly.
Estimated: at 72 MHz CPU clock with all peripherals active, the LPC2368FBD100 typically draws 40-55 mA from Vdd (3.3 V). Power dissipation is therefore ~150 mW, well within the LQFP-100 thermal resistance of approximately 50 C/W (per NXP package data). No heatsink is required, but designers should still provide continuous copper under the exposed die-pad-adjacent ground leads for best thermal relief in enclosed industrial housings.
The on-chip Ethernet MAC drives MII/RMII signals at 25 MHz / 50 MHz respectively - keep these traces over a continuous ground plane and series-terminate (33 ohm) near the MAC if the PHY is more than 50 mm away. USB D+/D- traces require 90-ohm differential impedance and should not have stubs; route them on the top layer only and keep total length below 50 mm.
合規資訊
RoHS and REACH compliant per NXP product page. Not AEC-Q100 qualified - this is an industrial-grade part (-40 C to +85 C). For automotive body modules the LPC2368 is generally acceptable in non-safety nodes but safety-critical ECUs should use an AEC-Q100 qualified MCU such as the NXP S32K series.
