FAQ

What is the maximum operating frequency and core architecture of the LPC844M201JBD64E?

The LPC844M201JBD64E features an Arm Cortex-M0+ processor core (revision r0p1) with a maximum CPU frequency of 30 MHz. It includes a single-cycle multiplier and fast single-cycle I/O port, delivering efficient real-time performance while maintaining low power consumption. The core is supported by an integrated Nested Vectored Interrupt Controller (NVIC) and system tick timer, making the LPC844M201JBD64E suitable for deterministic control tasks in industrial and portable applications.

Does the LPC844M201JBD64E support capacitive touch sensing, and how many electrodes can it handle?

Yes, the LPC844M201JBD64E integrates a dedicated Capacitive Touch Interface supporting up to nine electrodes: eight X-sensor inputs (CAPT_X0 through CAPT_X8) and two Y-sensor inputs (CAPT_YL and CAPT_YH). This hardware-accelerated engine performs touch scanning independently of the CPU, enabling low-power, responsive touch buttons or sliders. Electrode assignments map to specific GPIO pins (e.g., PIO1_0 through PIO1_9), all accessible in the LQFP64 package used by the LPC844M201JBD64E.

What are the analog capabilities of the LPC844M201JBD64E, particularly regarding ADC and DAC?

The LPC844M201JBD64E includes a 12-bit successive-approximation ADC with up to 12 input channels and a maximum sample rate of 1.2 Msps, supporting two independent conversion sequences for flexible sensor monitoring. It also integrates two 10-bit DACs: DACOUT_0 (mapped to PIO0_17) and DACOUT_1 (mapped to PIO0_29), each capable of generating precise analog output voltages for calibration, biasing, or actuator control-key features distinguishing the LPC844M201JBD64E from entry-level MCUs.

How does the LPC844M201JBD64E manage ultra-low-power operation, especially in deep power-down mode?

The LPC844M201JBD64E supports deep power-down mode with typical current draw below 1 µA. It can be woken by external events on PIO0_4 (WAKEUP pin) or the RESET pin, or internally via the Self-Wake-up Timer (WKT) clocked by the low-power oscillator or external source. The WKT remains active in deep power-down, enabling precise periodic wake-up intervals (e.g., every 100 ms) without external components-making the LPC844M201JBD64E ideal for battery-powered edge devices requiring multi-year operation.

Is the LPC844M201JBD64E pin-compatible with other members of the LPC84x family, and what package does it use?

Yes, the LPC844M201JBD64E uses the LQFP64 package (SOT314-2, 10 × 10 × 1.4 mm) and shares identical pinout with other LPC84x LQFP64 variants including LPC845M301JBD64. All GPIO, peripheral, power, and debug signals occupy the same physical positions-enabling hardware compatibility across the family. This allows design reuse and seamless migration (e.g., upgrading to higher SRAM or peripheral count) without PCB changes, provided firmware accommodates functional differences.
