NXP Semiconductors LPC824M201JHI33E

Overview

LPC824M201JHI33E from NXP Semiconductors is a 32-bit ARM Cortex-M0+ microcontroller operating at up to 30 MHz, featuring 32 KB flash, 8 KB SRAM, a 12-bit ADC with 12 input channels, one analog comparator, and 29 GPIO pins. It integrates four I²C interfaces (one Fast-mode Plus), three USARTs, two SPI controllers, and a flexible State Configurable Timer (SCTimer/PWM) for motor control and sensor interface applications.

For engineers reviewing the LPC824M201JHI33E datasheet, LPC824M201JHI33E pinout, LPC824M201JHI33E application, or LPC824M201JHI33E equivalent, key selection considerations include its HVQFN33 package, 1.8–3.6 V supply range, -40 °C to +105 °C industrial temperature grade, self-wake-up timer support, and switch-matrix configurable peripheral routing.

Technical Context

The LPC824M201JHI33E implements an ARM Cortex-M0+ core (r0p1) with single-cycle I/O, nested vectored interrupt controller (NVIC), and Serial Wire Debug (SWD). Its AHB multilayer matrix interconnect enables concurrent access to flash, SRAM, and peripherals including DMA (18 channels), CRC engine, and MTB trace buffer.

Peripherals are dynamically routed via a hardware switch matrix: USART, SPI, I²C, SCTimer inputs/outputs, ADC triggers, and comparator outputs can be assigned to any of 29 GPIO pins (excluding power/ground), enabling board-level flexibility without pinout constraints. The SCTimer supports capture, match, and PWM generation with multiplexed input sources including ADC interrupts and comparator outputs.

FAQ

What is the maximum operating frequency of the LPC824M201JHI33E?

The LPC824M201JHI33E operates at a maximum CPU frequency of 30 MHz using its ARM Cortex-M0+ core. This speed is achievable with the internal 12 MHz RC oscillator (trimmed to ±1.5 %), external crystal (1–25 MHz), or PLL-derived clock. The core features a two-stage pipeline and single-cycle multiplier for efficient execution at this rate.

Does the LPC824M201JHI33E support in-system programming (ISP)?

Yes, the LPC824M201JHI33E supports In-System Programming (ISP) via its built-in ROM bootloader. It accepts commands over USART0 (using PIO0_12 as ISP entry pin) to erase and program flash memory without external debug hardware. The on-chip ROM also provides APIs for flash IAP, integer division, and peripheral configuration.

How many ADC input channels does the LPC824M201JHI33E have, and what is its resolution?

The LPC824M201JHI33E integrates a 12-bit successive-approximation ADC with up to 12 input channels (ADC_0 through ADC_11). It supports two independent conversion sequences, internal/external trigger sources, and sample rates up to 1.2 million samples per second - enabling high-fidelity analog signal acquisition for sensor and control applications.

What debug interface does the LPC824M201JHI33E use, and which pins are required?

The LPC824M201JHI33E uses Serial Wire Debug (SWD) as its primary debug interface, requiring only two pins: SWDIO (PIO0_2) and SWCLK (PIO0_3). It supports four hardware breakpoints and two watchpoints. JTAG boundary scan is also supported but requires five pins and is active only in boundary scan mode.

Can the LPC824M201JHI33E wake up from Deep power-down mode using an external signal?

Yes, the LPC824M201JHI33E can wake up from Deep power-down mode via the PIO0_4 pin configured as WAKEUP. A LOW-going pulse ≥50 ns on this pin exits Deep power-down and initiates boot sequence. External pull-up is required before entering Deep power-down, and no movable function may be assigned to PIO0_4 if wake-up is needed.
