NXP Semiconductors LPC844M201JHI33E

Overview

LPC844M201JHI33E from NXP Semiconductors is a 32-bit Arm Cortex-M0+ microcontroller operating at up to 30 MHz, featuring 64 KB flash, 8 KB SRAM, two 10-bit DACs, one 12-bit ADC (12-channel), and capacitive touch interface - deployed in compact HVQFN33 packaging for space-constrained industrial sensor nodes and portable control systems.

For engineers reviewing the LPC844M201JHI33E datasheet, LPC844M201JHI33E pinout, LPC844M201JHI33E application, or LPC844M201JHI33E equivalent, key selection criteria include its 29 GPIO count, dual DAC support for analog output generation, self-wake-up timer with external clock input (WKTCLKIN), and switch-matrix–enabled peripheral routing flexibility across I2C, USART, and SPI interfaces.

Technical Context

The LPC844M201JHI33E implements an Arm Cortex-M0+ core (r0p1) with single-cycle I/O and 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 (18/24/30 MHz), PLL for CPU scaling, and low-power oscillators for deep power-down wake-up.

Digital peripherals include a 25-channel DMA controller, CRC engine, and programmable switch matrix enabling dynamic assignment of UART, I2C, SPI, SCTimer/PWM, and CTIMER functions to any non-power pin. Analog subsystem comprises a 12-bit ADC (1.2 Msps, dual sequence mode), comparator with five inputs, and two independent 10-bit DACs with dedicated output pins (DACOUT_0/DACOUT_1).

FAQ

What is the maximum operating frequency of the LPC844M201JHI33E?

The LPC844M201JHI33E operates at a maximum CPU frequency of 30 MHz, achieved via its internal Free Running Oscillator (FRO) or PLL. This speed is maintained across the full 1.8 V–3.6 V supply range and –40 °C to +105 °C temperature range, ensuring deterministic real-time performance in industrial environments.

Does the LPC844M201JHI33E include built-in DACs, and what are their specifications?

Yes, the LPC844M201JHI33E integrates two independent 10-bit DACs. DACOUT_0 is routed to PIO0_17 and DACOUT_1 to PIO0_29. Both support rail-to-rail output, 1 µs settling time, and operate across the full 1.8–3.6 V supply range - enabling precision analog output for sensor biasing, calibration, or actuator control without external components.

How many GPIO pins does the LPC844M201JHI33E provide in the HVQFN33 package?

The LPC844M201JHI33E provides 29 general-purpose I/O pins in the HVQFN33 package. These include dedicated analog-capable pins (ADC/DAC/comparator), debug pins (SWDIO/SWCLK), and configurable digital I/O with pull-up/down, open-drain, and input inverter options - all accessible through the flexible switch matrix.

Can the LPC844M201JHI33E wake from deep power-down mode, and how?

Yes, the LPC844M201JHI33E supports wake-up from deep power-down mode via three sources: the dedicated WAKEUP pin (PIO0_4), the RESET pin (PIO0_5), or the Self-Wake-Up Timer (WKT) using either the internal FRO or external clock on WKTCLKIN (PIO0_28). This enables µA-level sleep with precise, event-driven resumption.

Is the LPC844M201JHI33E pin-compatible with other LPC84x variants in HVQFN33?

Yes, the LPC844M201JHI33E shares identical pinout, package dimensions, and thermal pad layout with other HVQFN33 variants in the LPC84x family, including LPC845M301JHI33 and LPC824M201JHI33. This allows hardware reuse across performance tiers, though firmware and peripheral configuration must align with each variant's feature set.
