LPC11C14FBD48/301

LPC11C14FBD48/301 - 32KB Flash Cortex-M0 MCU w/ CAN | NXP

The NXP LPC11C14FBD48/301 is an ARM Cortex-M0 based 32-bit microcontroller running at up to 50 MHz, with 32 KB of on-chip flash, 8 KB of SRAM, and an integrated C_CAN controller, housed in a 48-pin LQFP (7x7 mm) package. It belongs to the LPC1100 series, designed as a low-cost upgrade path for 8/16-bit MCU applications, offering higher performance with a simple Thumb/Thumb-2 instruction set and reduced code size compared to legacy architectures. A microcontroller (MCU) is a single-chip computer that integrates a CPU core, non-volatile program memory (flash), volatile data memory (SRAM), and peripherals such as timers, communication interfaces, and analog blocks into one package. MCUs sit at the bottom of the embedded computing hierarchy: MCU -> microcontroller -> embedded processor -> semiconductor device. The Cortex-M0 class represents the smallest, lowest-power variant of the ARMv6-M architecture, with deterministic interrupt handling that makes it well-suited for real-time control. The on-chip C_CAN conforms to the ISO 11898-1 CAN 2.0B standard, eliminating the need for an external CAN transceiver controller in bus-node designs. Key features include a 50 MHz Cortex-M0 core with single-cycle multiplier, 32 KB flash with In-System Programming (ISP) and In-Application Programming (IAP), 8 KB SRAM, a 12 MHz internal RC oscillator trimmable to 1% accuracy, an integrated C_CAN 2.0B controller, one SSP/SPI, one I2C, one UART, four general-purpose timers, a 10-bit ADC with up to 8 input channels, and a windowed watchdog timer. Power consumption is rated at approximately 10 mA active and 1 mA in deep-sleep mode at 3.3 V. The architecture uses a 3-stage pipeline with the ARMv6-M Thumb instruction set. Code density is significantly improved over 8/16-bit cores, allowing more functionality in the same 32 KB flash budget. The integrated C_CAN block uses 256-byte message RAM, supporting both standard (11-bit) and extended (29-bit) identifiers, which simplifies fieldbus node designs. The 12 MHz IRC can be trimmed in software to within 1% across the full operating range, often eliminating the need for an external crystal. Typical applications include CAN node endpoints in industrial automation, e-metering and smart metering, LED lighting controllers, alarm system panels, white goods, sensor hubs, and low-cost building-automation gateways. The integrated CAN controller is the standout feature in this price/performance class - the part is positioned wherever an 8-bit MCU is being replaced but a CAN interface is also required. When designing with this MCU, place a 100 nF decoupling capacitor adjacent to each VDD pin and connect all VSS pins to a solid ground plane to reduce digital switching noise coupling into the ADC. The CAN TXD/RXD lines still require an external 3.3 V CAN transceiver such as the TJA1050 or SN65HVD230 to drive the bus.

Typical uses include industrial control modules, USB-to-serial or USB-connected data-acquisition equipment, compact sensor interfaces, building-control nodes, and low-cost embedded products. In an analog measurement design, the 12-bit ADC can acquire sensor signals while the Cortex-M0+ core performs filtering, calibration, and data packaging. In a USB peripheral, the integrated USB interface can reduce external connectivity requirements while the MCU manages the application protocol. Design consideration: verify the operating voltage, peripheral pin multiplexing, USB electrical requirements, clock configuration, and programming interface against the manufacturer datasheet before finalizing the PCB. Use the specified decoupling and programming-interface layout, and account for every alternate-function pin used by the application. This page consolidates the manufacturer specifications, commercial inquiry workflow, package information, application guidance, and cross-reference status for LPC11U68JBD48K into one engineering-focused reference.

LPC11U68JBD64K - 50MHz Cortex-M0+ 256KB MCU | NXP

NXP Semiconductors LPC11U68JBD64K is an entry-level 32-bit embedded microcontroller based on Arm Cortex-M0+ and Cortex-M0 cores, operating at up to 50 MHz and providing 256 KB of flash memory in a 64-LQFP package measuring 10 mm by 10 mm. The device is positioned as a low-cost migration path from 8-bit and 16-bit microcontroller designs while retaining a 32-bit architecture, a compact instruction set, and flexible configuration. A microcontroller is a semiconductor integrated circuit that combines a processor core, program memory, data memory, and peripherals on one die. In the product hierarchy, the LPC11U68JBD64K is an embedded microcontroller, then a 32-bit microcontroller, and ultimately a general-purpose semiconductor. The Arm Cortex-M0+ architecture is designed for compact embedded-control code, while the presence of Cortex-M0-compatible family information supports simple control-oriented product designs. The principal verified characteristics are a maximum CPU frequency of 50 MHz, 256 KB of flash, a 32-bit CPU, Arm Cortex-M0+/M0 family architecture, and a 64-LQFP surface-mount package. The NXP product page identifies LPC11U68JBD64 as active. This combination makes the LPC11U68JBD64K relevant to embedded control, IoT device, industrial automation, motor-control, metering, and low-power board applications where a compact 32-bit control platform is required. The LPC11Uxx family is intended to replace conventional 8-bit and 16-bit microcontroller implementations with a more capable 32-bit architecture. Its operating frequency of up to 50 MHz provides additional processing headroom for protocol handling, control logic, and state management, while the simple Arm instruction set can reduce software complexity compared with more elaborate embedded processor architectures. Exact RAM, peripheral, voltage, and timing details must be confirmed in the manufacturer datasheet before schematic or firmware design begins. Typical application opportunities include smart metering, connected sensors, compact industrial controllers, motor-control supervisory logic, appliance controls, and low-power IoT nodes. In these systems, the 256 KB flash capacity accommodates a bootloader, application firmware, configuration data, and protocol code. The 10 mm by 10 mm LQFP package also supports conventional surface-mount assembly while providing more exposed perimeter pins than a small leadless package. Designers should use the official NXP data sheet as the controlling source for pin assignment, power requirements, clocking, peripherals, programming, and package dimensions. The LPC11U68JBD64K is supported by the NXP LPC11U00 CMSIS device family package, providing a defined software-device and peripheral baseline for embedded toolchains. This product page consolidates verified manufacturer and distributor information, pricing availability, package details, datasheet links, application context, and design cautions. It also distinguishes confirmed specifications from unavailable data rather than estimating missing electrical or pin-level values, helping engineers make a safer sourcing and design decision.
