NXP Semiconductors LPC802M011JDH20J

Overview

LPC802M011JDH20J from NXP Semiconductors is a 32-bit ARM Cortex-M0+ microcontroller operating at up to 15 MHz, featuring 16 KB flash, 2 KB SRAM, a 12-bit ADC with 12-channel input, an analog comparator, and dual I/O power supply (VDD/VDDIO) for level-shifting-designed for low-cost industrial sensor nodes and portable control systems.

For engineers reviewing the LPC802M011JDH20J datasheet, LPC802M011JDH20J pinout, LPC802M011JDH20J application, or LPC802M011JDH20J equivalent, key selection criteria include its TSSOP20 dual-supply configuration, 16 GPIOs with switch-matrix routing, 480 kS/s ADC sampling rate, SWD debug interface, and support for deep power-down wake-up on eight pins.

Technical Context

The LPC802M011JDH20J implements an ARM Cortex-M0+ core (r0p1) with single-cycle I/O and NVIC, paired with a multilayer AHB matrix and APB peripherals. Its dual-voltage I/O architecture separates VDD (core + right-side I/O) and VDDIO (left-side I/O), enabling inter-domain signal level shifting via the switch matrix.

Peripheral integration includes one 32-bit general-purpose timer with four match outputs, two USARTs routed through the switch matrix, one SPI controller, one I²C bus interface (Standard/Fast mode), and a self-wake-up timer clocked by FRO, LPOSc, or external input-supporting sleep, deep-sleep, power-down, and deep power-down modes with configurable wake sources.

FAQ

What is the maximum ADC sampling rate supported by the LPC802M011JDH20J?

The LPC802M011JDH20J supports a maximum ADC sampling rate of 480 kS/s, achievable using internal triggers and optimized conversion sequences. This rate enables accurate capture of fast-changing analog signals such as audio envelopes or motor current transients in resource-constrained designs. The 12-bit resolution and 12-channel multiplexing provide flexibility for multi-sensor systems without external muxing hardware.

Does the LPC802M011JDH20J support in-system programming (ISP) via UART?

Yes, the LPC802M011JDH20J supports In-System Programming (ISP) through its USART interface, leveraging on-chip ROM bootloader functionality. This allows firmware updates in the field without requiring a debugger or dedicated programmer. The device enters ISP mode when PIO0_12 is held LOW during reset, and communication proceeds at standard baud rates using UART0 or UART1 configured via the switch matrix.

How does the dual I/O power supply (VDDIO) function in the LPC802M011JDH20J?

The LPC802M011JDH20J uses separate VDD (Pin 15) and VDDIO (Pin 2) supplies to isolate left-side and right-side I/O banks. VDDIO powers pins PIO0_0 to PIO0_15 (left side), while VDD powers the core and right-side pins (e.g., PIO0_16/PIO0_17). This architecture enables native level shifting-e.g., connecting 1.8 V sensors to VDDIO pins and 3.3 V transceivers to VDD pins-without external translators.

Which pins on the LPC802M011JDH20J support wake-up from deep power-down mode?

Eight GPIO pins on the LPC802M011JDH20J support wake-up from deep power-down mode: PIO0_4, PIO0_8, PIO0_9, PIO0_10, PIO0_11, PIO0_13, PIO0_15, and PIO0_17. A LOW-going pulse as short as 50 ns on any of these pins exits deep power-down and initiates wake-up sequence. External pull-up resistors are required before entering deep power-down to ensure reliable triggering.

Can the LPC802M011JDH20J operate without an external crystal oscillator?

Yes, the LPC802M011JDH20J includes an internal Free Running Oscillator (FRO) trimmed to ±1 % accuracy across 0–70 °C, providing selectable 9 MHz, 12 MHz, or 15 MHz system clocks. This eliminates the need for external crystals in cost-sensitive or space-constrained applications. The FRO is factory-calibrated and accessible via ROM API, supporting full-speed operation without external timing components.
