LPC1767FBD100K - 100MHz Cortex-M3 512KB MCU | NXP

NXP LPC1767FBD100K is a 32-bit ARM Cortex-M3 microcontroller rated at 100 MHz, with 512 KB of flash memory, 64 KB of SRAM, and an Ethernet MAC, supplied in a 100-pin LQFP package measuring 14 x 14 mm. The device combines four UARTs, three SSP/SPI interfaces, three I2C interfaces, I2S support, an eight-channel 12-bit ADC, a 10-bit DAC, motor-control PWM, a quadrature encoder interface, and an eight-channel DMA controller. A microcontroller is a semiconductor integrated circuit dedicated to embedded control. Its hierarchy extends from an embedded processor to a microcontroller, an ARM Cortex-M3 core, and finally a general-purpose microcontroller with integrated flash, SRAM, analog converters, and communication peripherals. The LPC1767 therefore combines general-purpose firmware execution with multiple peripheral engines that reduce the need for separate interface components in connected embedded equipment. The LPC1767 family is positioned for embedded applications requiring high integration and low power consumption. Its 100 MHz Cortex-M3 processor provides substantially more arithmetic capability than an 8- or 16-bit control MCU while retaining the deterministic peripheral architecture useful for communications, data acquisition, and motor-control systems. The 512 KB program memory supports a larger embedded code base than devices with only tens or hundreds of kilobytes of flash, while 64 KB of SRAM accommodates working buffers and protocol stacks. Communication capability is a major feature. The integrated Ethernet MAC supports networked embedded designs, while the four UARTs, three SSP/SPI interfaces, three I2C interfaces, and I2S interface cover serial links to sensors, converters, storage, displays, and audio devices. The eight-channel 12-bit ADC and 10-bit DAC support analog measurement and signal generation. An eight-channel DMA controller can transfer data between peripherals and memory, reducing CPU involvement in data movement. Typical LPC1767 applications include industrial Ethernet equipment, data acquisition modules, building-control gateways, communications equipment, motor controllers, and embedded test systems. It is particularly useful when several serial interfaces and analog channels must coexist on one controller. The 100-LQFP package exposes the extensive pin set but requires a substantially larger PCB footprint than a small-outline package. For a new PCB, preserve the LPC1767FBD100K footprint and verify every Ethernet, analog, power, and boot-strapping connection against the manufacturer pinout. Do not treat a related LPC17xx device as an automatic replacement because memory size, CAN availability, peripheral options, or pin multiplexing may differ. For an assembled board, verify the exact suffix, Ethernet implementation, power rails, crystal circuit, and boot configuration before sourcing a replacement. This page consolidates manufacturer and distributor information, package characteristics, interface capabilities, and practical replacement guidance. It distinguishes verified LPC1767FBD100K facts from unavailable details and identifies alternatives that require explicit pin, peripheral, and firmware validation before production use.

LPC1768FBD100K

LPC1768FBD100K - 100MHz Cortex-M3 512KB Flash MCU | NXP

The NXP Semiconductors LPC1768FBD100K is an ARM Cortex-M3 32-bit microcontroller with a 100 MHz core, 512 KB of on-chip flash memory and 64 KB of SRAM, integrated in a 100-lead LQFP (14 x 14 mm) surface-mount package. It operates from a single 2.4 V to 3.6 V supply and adds an Ethernet MAC, a USB Device/Host/OTG controller, an 8-channel DMA engine and 8-channel 12-bit ADC. What is an ARM Cortex-M3 microcontroller? A microcontroller is a single integrated circuit containing a processor core, memory and peripherals on one die. The Cortex-M3 is a 32-bit ARM processor architecture designed for embedded control: it uses the Thumb instruction set, has no separate cache or memory-management unit, and delivers deterministic interrupt-driven performance at low power. Within the hierarchy, the LPC1768 belongs to the LPC17xx family of NXP microcontrollers, which sit between simple 8-bit MCUs and higher-end Cortex-M4/M7 application processors. Key features of the LPC1768 include 512 KB (512K x 8) flash program memory, 64 KB of data SRAM, an 8-channel 12-bit successive-approximation ADC, a single 10-bit DAC, four UARTs, two CAN 2.0B controllers, three SSP/SPI interfaces, three I2C interfaces, an I2S interface, motor-control PWM and an Ethernet MAC with MII/RMII. The 8-channel DMA controller allows peripheral transfers to run with minimal CPU intervention. Technically, the device pairs the Cortex-M3 core with a nested vectored interrupt controller for fast, prioritized event handling, and provides a 100 MHz maximum CPU clock from an internal or external oscillator. The integrated Ethernet MAC supports 10/100 Mb/s traffic, and the USB controller can operate as Device, Host or OTG, making the part suitable for gateway, data-logger and connected-instrument designs without a discrete USB or Ethernet PHY. Typical applications include industrial Ethernet gateways, USB-to-serial and protocol converters, motor and motion controllers using the PWM and CAN channels, data acquisition and test equipment using the 12-bit ADC, and networked sensor nodes using the Ethernet MAC with the 10/100 Mb/s PHY. A key design consideration is that the LQFP-100 (14 x 14 mm) footprint demands careful escape routing: with a 0.5 mm pitch, high-speed USB and Ethernet differential pairs need continuous reference planes and short, symmetric traces, and decoupling should be placed directly at each VDD pin. This page consolidates distributor pricing, verified drop-in alternatives from the NXP LPC17xx family, a parameter-by-parameter comparison table and practical PCB design notes that are not found together in the manufacturer datasheet.

The 512 KB flash capacity provides room for networking stacks, protocol handlers, control firmware, and application logic, while the 100 MHz Cortex-M3 core supports deterministic multitasking and peripheral servicing. A critical design consideration is the fine-pitch 100-TFBGA footprint. PCB layout must provide adequate escape routing, power and ground distribution, and manufacturing capability for the package. Firmware developers must also configure clocks, pins, memory, and peripherals for the exact LPC1768UKJ variant rather than relying only on generic LPC1768 documentation. This page combines the verified distributor description, family-level technical context, package information, sourcing details, and engineering-oriented selection guidance. It is intended to help engineers identify the correct MCU, plan a compatible board, and distinguish verified facts from details that still require confirmation in the official documentation.

Four UARTs, two CAN channels, three SSP/SPI interfaces, three I²C interfaces, and I²S reduce the need for external communication controllers. Motor-control PWM further supports actuator and power-control designs. The supplied NXP product information confirms the LPC1768UK family identity, while distributor records identify LPC1768UKZ as the ordering variant associated with a 100-pin, 3.3 V device. Exact voltage ranges, pin assignments, current limits, package dimensions, temperature limits, and clock-tree details require confirmation in the manufacturer datasheet because those values are not fully included in the supplied search extracts. The LPC1768UKZ should therefore be selected against the complete datasheet and board-level requirements before release to production. Typical applications include industrial Ethernet controllers, USB-connected embedded systems, CAN-based automation equipment, motor-control systems, data loggers, communications equipment, and multi-channel sensor acquisition systems. The combination of Ethernet, USB, CAN, high-speed serial interfaces, and analog conversion allows a compact design to consolidate several functions normally distributed across separate ICs. This is particularly useful for industrial controllers, building-automation equipment, test systems, and connected embedded products. A critical design consideration is package and PCB verification. The LPC1768UKZ uses a high-pin-count BGA package according to distributor records, so escape routing, via-in-pad or fanout strategy, exposed-pad handling, assembly capability, and thermal performance must be confirmed before layout release. Software migration should also account for peripheral-instance names, clock configuration, pin multiplexing, startup code, and the exact Cortex-M memory map. This page consolidates the verified NXP family specifications, distributor package identification, pricing references, and application guidance. It distinguishes confirmed facts from missing datasheet details and avoids treating search-snippet information as a complete electrical characterization. Engineers should use the manufacturer datasheet for final pinout, timing, power, EMC, and qualification decisions.

According to the NXP product page, it is offered in the LQFP144 footprint. A microcontroller (MCU) is a single-chip computer that integrates a CPU core, memory, and programmable peripherals. The Cortex-M3 is a 32-bit RISC processor core designed by ARM for deterministic, low-latency embedded applications. It sits in the broader hierarchy of microcontrollers -> embedded processors -> semiconductors. LDOs themselves are voltage regulators, but in this case LPC1788FBD144 is a microcontroller, not an LDO - clarification is important because the LPC17xx family is sometimes confused with the TPS7A4701 LDO family due to similar prefix letters. Key features of the LPC1788FBD144 include up to 120 MHz CPU clock, 512 KB on-chip flash program memory, 96 KB SRAM, an 8-channel DMA controller, an external memory controller (EMC), USB 2.0 full-speed Device/Host/OTG, 10/100 Ethernet MAC, an LCD controller supporting TFT panels up to 1024x768, CAN, I2C, I2S, SPI, UART, 12-bit ADC, 10-bit DAC, PWM, and a Real-Time Clock (RTC).

NXP describes the LPC18xx family as pin- and software-compatible with many related devices, allowing engineers to reuse software and consider family variants when product requirements change. Detailed electrical, peripheral, and environmental limits are available in the linked manufacturer documentation. The device uses the Arm Cortex-M3 architecture, whose efficient instruction set and hardware interrupt handling are suitable for real-time embedded control. Its combination of flash, SRAM, and processing speed allows more application code and data to remain on-chip than in smaller general-purpose microcontrollers. This can reduce external memory requirements in networking, industrial-control, communications, and embedded-processing equipment, subject to the complete peripheral configuration of the selected device. Typical uses include industrial automation equipment, USB-connected embedded systems, communications controllers, and compact control platforms. In each case, the MCU can execute control logic while its on-chip memory stores firmware and working data. Engineers should verify the required USB, Ethernet, CAN, LCD, storage, and other peripheral functions against the exact LPC1823 configuration before selecting it for a design. A critical design consideration is BGA assembly and inspection. The 100-ball TFBGA-100 footprint requires a compatible land pattern, controlled reflow, and appropriate solder-joint inspection because hidden joints are not visually accessible after assembly. Firmware should also be validated for the exact LPC1823 peripheral set because related LPC18xx devices can differ in memory and integrated interfaces. This product page consolidates verified manufacturer and distributor information, exact pricing references, same-package family alternatives, and practical design considerations. It also distinguishes confirmed LPC1823JET100E attributes from parameters that still require confirmation from the full NXP datasheet, helping engineers make evidence-based sourcing and design decisions.

It is part of the LPC1800 series, optimized for industrial control, HMI, motor drive, and secure embedded applications where external flash memory is acceptable. A microcontroller (MCU) is an integrated circuit that combines a CPU core, volatile memory (SRAM), non-volatile memory (Flash/ROM or external), and programmable peripherals on a single chip. The Cortex-M3 is an ARM-designed 32-bit RISC core featuring Thumb-2 instruction set, deterministic interrupts, and a Nested Vectored Interrupt Controller (NVIC). LPC1800 MCUs sit in NXP's high-performance general-purpose MCU hierarchy (MCU -> Cortex-M3 -> LPC1800 series -> LPC18Sxx sub-family), providing more compute and peripherals than Cortex-M0/M0+ parts while remaining lower-cost than Cortex-M4 parts. Key features include 200 kB SRAM, 4 kB EEPROM, AES hardware decryption accelerator, two HS-USB ports with on-chip PHY, 10/100 Ethernet MAC with MII/RMII interface, Quad-SPI Flash Interface (SPIFI), EMC supporting SRAM/SDRAM/NOR/NAND, up to 165 GPIO pins, four UARTs, three I2C, two CAN, two SSP/SPI controllers, and a 10-bit ADC with 8 channels. The LBGA256 (17x17 mm) package supports high-density I/O for graphics and external memory expansion. The LPC18S30FET256 uses NXP's standard peripherals library and CMSIS support, enabling rapid firmware development. Its security subsystem (hardware AES + unique device ID + secure boot) makes it suitable for anti-counterfeiting and tamper-resistant designs. The ROMless architecture requires external SPIFI or EMC flash for code storage, giving designers flexibility in memory density and updateability. Typical applications include industrial Human-Machine Interfaces (HMI), motor control and drives, factory automation controllers, secure POS terminals, and embedded networking gateways. When designing with the LPC18S30FET256, ensure proper decoupling (100 nF per VDD pin, 4.7 uF bulk), matched-impedance routing for HS-USB and Ethernet differential pairs, and a 12 MHz external crystal with correct load capacitance. The ROMless boot sequence must be validated using the boot ROM via the ISP/UART or SPIFI interface. Choose LPC18S30FET256E for the industrial-grade variant with extended temperature range.

LPC2104BBD48 - 32-bit ARM7 MCU 128kB Flash LQFP-48 | NXP
LPC2104BBD48

LPC2104BBD48 - 32-bit ARM7 MCU 128kB Flash LQFP-48 | NXP

The NXP Semiconductors LPC2104BBD48 is a single-chip 32-bit ARM7TDMI-S microcontroller with 128 kB of embedded high-speed flash memory, 16 kB of SRAM, real-time emulation, and embedded Trace support, supplied in a 48-lead LQFP package (SOT313-2, 7 mm x 7 mm x 1.4 mm body, 0.5 mm pitch). It operates at up to 60 MHz from a 1.65 V to 1.95 V core supply and provides 32 GPIO pins for general-purpose use. A microcontroller (MCU) is an integrated circuit that combines a CPU core, program memory (typically flash), data memory (RAM), and a rich set of peripherals on a single die. The LPC2104 sits inside the broader hierarchy of: microcontroller -> embedded microprocessor -> integrated circuit -> semiconductor. Its ARM7TDMI-S core is a 16/32-bit RISC processor from the ARM7 family, historically one of the most widely deployed 32-bit MCU cores in industrial, automotive, and consumer embedded designs. Key features of the LPC2104BBD48 include 128 kB of on-chip ISP/IAP flash, 16 kB of SRAM, two 32-bit timers, a 10-bit ADC, I2C, SPI, and UART serial interfaces, plus a Real-Time Clock (RTC) with battery backup support. The device also integrates a Vectored Interrupt Controller (VIC) for fast deterministic interrupt response, and offers JTAG and EmbeddedICE for in-system debug. The LPC2104 uses a 128-bit wide internal flash bus to deliver sustained instruction throughput from flash despite the 0-wait-state architecture, and supports a 16-bit Thumb instruction set to improve code density. Power management includes two low-power modes (idle and power-down), an external interrupt wake-up path, and a brown-out detector to protect flash integrity. Typical applications include industrial control nodes, embedded sensor hubs, low-power handheld terminals, RS-485/Modbus gateway controllers, and legacy ARM7 retrofits. The combination of small LQFP-48 footprint, ample flash, and proven ARM7 toolchain makes it well-suited to brownfield designs where ARM Cortex migration is not yet required. When designing with the LPC2104, plan the crystal/oscillator layout per the datasheet because the internal PLL is sensitive to noise on VREF/VSSA; place 100 nF and 10 uF decoupling capacitors close to each supply pin. Note that this part is reported as obsolete/EOL on at least one distributor source, so plan second-source or migration path early.
