For engineers reviewing the LPC844M201JHI33Y datasheet, LPC844M201JHI33Y pinout, LPC844M201JHI33Y application, or LPC844M201JHI33Y equivalent, key selection criteria include its 29 GPIO count, dual DAC outputs, low-power wake-up timer clock input (WKTCLKIN), self-wake-up capability from deep power-down, and switch-matrix–based peripheral routing flexibility across I2C, USART, and SPI functions.

Technical Context

The LPC844M201JHI33Y implements an Arm Cortex-M0+ core with single-cycle I/O and nested vectored interrupt controller (NVIC), paired with a multilayer AHB matrix and Serial Wire Debug (SWD) interface. Its clock system integrates a trimmable Free Running Oscillator (FRO) at ±1% accuracy, programmable PLL, and external crystal/oscillator support up to 25 MHz.

Digital peripherals include a 25-channel DMA controller, CRC engine, input pattern match engine, and flexible switch matrix enabling dynamic assignment of UART, SPI, I2C, SCTimer/PWM, and analog functions to 29 available pins. Analog subsystem comprises a 12-bit ADC with dual conversion sequences, comparator with five inputs, and two independent 10-bit DACs with dedicated output pins (DACOUT_0 on PIO0_17, DACOUT_1 on PIO0_29).

FAQ

What is the maximum operating frequency of the LPC844M201JHI33Y?

The LPC844M201JHI33Y operates at a maximum CPU frequency of 30 MHz, achieved via its internal Free Running Oscillator (FRO) or PLL. The FRO delivers ±1% accuracy across 0 °C to 70 °C, and the PLL enables full-speed operation without requiring an external high-frequency crystal - making the LPC844M201JHI33Y suitable for timing-critical control loops in motor or lighting applications.

How many analog-to-digital converter (ADC) channels does the LPC844M201JHI33Y support?

The LPC844M201JHI33Y integrates a single 12-bit ADC with up to 12 input channels (ADC_0 through ADC_11), supporting sample rates up to 1.2 Msps and two independent conversion sequences. Channel ADC_11 is mapped to PIO0_4, which also serves as the WAKEUP pin - requiring careful configuration to avoid conflict between ADC sampling and deep power-down wake functionality in the LPC844M201JHI33Y.

Does the LPC844M201JHI33Y include built-in digital-to-analog converters (DACs)?

Yes, the LPC844M201JHI33Y features two independent 10-bit DACs: DACOUT_0 on PIO0_17 and DACOUT_1 on PIO0_29. Both outputs support voltage generation with monotonicity and <±1 LSB integral nonlinearity, enabling analog biasing, sensor calibration, or reference signal generation - all without external DAC components in the LPC844M201JHI33Y design.

What package type is used for the LPC844M201JHI33Y?

The LPC844M201JHI33Y uses the HVQFN33 package: a 5 mm × 5 mm, 0.85 mm height, thermally enhanced no-lead quad flat package with 33 terminals and an exposed thermal pad. This package supports high-density PCB layouts and efficient heat dissipation in space-constrained applications such as wearables and sensor modules using the LPC844M201JHI33Y.

Can the LPC844M201JHI33Y wake up from deep power-down mode using an external signal?

Yes, the LPC844M201JHI33Y supports wake-up from deep power-down mode via two dedicated pins: PIO0_4 (WAKEUP) and PIO0_5 (RESET). A LOW-going pulse as short as 50 ns on either pin exits deep power-down and initiates wake-up sequence. The WAKEUP pin (PIO0_4) must remain unassigned to movable functions if used - a critical constraint confirmed in the LPC844M201JHI33Y datasheet Section 7.2.
