It operates across −40 °C to +105 °C and targets voice-enabled edge nodes, industrial sensor hubs, and USB-connected IoT endpoints.

For engineers reviewing the LPC54113J256UK49Z datasheet, LPC54113J256UK49Z pinout, LPC54113J256UK49Z application, or LPC54113J256UK49Z equivalent, key selection considerations include dual-core real-time partitioning, WLCSP49 package constraints, crystal-less USB timing compliance, DMIC subsystem resource allocation, and Flexcomm interface multiplexing flexibility.

Technical Context

The LPC54113J256UK49Z integrates two independent 32-bit processors: the Cortex-M4 (with FPU and MPU) and Cortex-M0+ (code- and tool-compatible), both running up to 150 MHz from a shared clock source. Its memory subsystem includes 256 KB on-chip flash with page erase, 192 KB distributed SRAM (SRAMX/SRAM0/SRAM1/SRAM2), and ROM-based USB drivers supporting HID/CDC/MSC/DFU.

Peripherals are organized around an AHB matrix and APB bridges, with eight Flexcomm interfaces (each configurable as USART/SPI/I2C, two with I2S), a dedicated DMIC subsystem with hardware voice activity detection, and a 24-bit multi-rate timer (MRT) for deterministic interrupt scheduling. Power management includes programmable PMU, deep power-down mode, and wake-up via USB, USART, SPI, or I2C slave activity.

FAQ

What is the maximum operating frequency of the LPC54113J256UK49Z?

The LPC54113J256UK49Z supports a maximum CPU frequency of 150 MHz for both the ARM Cortex-M4 and Cortex-M0+ cores. This frequency is achieved using the system PLL driven by the internal 12 MHz Free Running Oscillator (FRO), eliminating the need for an external high-frequency crystal while maintaining timing accuracy within ±1 % over voltage and temperature.

Does the LPC54113J256UK49Z support crystal-less USB operation?

Yes, the LPC54113J256UK49Z supports crystal-less USB 2.0 full-speed device operation using its internal FRO and software library (documented in Technical Note TN00031). This eliminates the need for an external 12 MHz crystal and associated load capacitors, reducing BOM cost and PCB area while meeting USB timing tolerance requirements.

How many ADC channels does the LPC54113J256UK49Z have, and what is its maximum sample rate?

The LPC54113J256UK49Z integrates a 12-bit ADC with 12 input channels and supports a maximum sample rate of 5.0 million samples per second. It provides two independent conversion sequences and connects to an on-chip temperature sensor, enabling high-throughput sensor fusion without external ADC components.

What package type is used for the LPC54113J256UK49Z?

The LPC54113J256UK49Z uses a WLCSP49 (Wafer-Level Chip-Scale Package) with 49 bumps arranged in a 7×7 array, measuring 3.436 × 3.436 × 0.525 mm and featuring a 0.4 mm bump pitch. This ultra-compact package is optimized for space-constrained portable and wearable applications.

Can the LPC54113J256UK49Z operate across extended temperature ranges?

Yes, the LPC54113J256UK49Z is rated for operation from −40 °C to +105 °C, making it suitable for industrial, automotive, and outdoor environments where thermal robustness is critical. Its internal oscillators-including the 12 MHz FRO trimmed to ±1 % accuracy-are specified across this full range.
