NXP Semiconductors LPC811M001JDH16J

Overview

LPC811M001JDH16J from NXP Semiconductors is a 32-bit ARM Cortex-M0+ microcontroller operating at up to 30 MHz, featuring 8 kB flash, 2 kB SRAM, and 14 GPIO pins. It integrates a state-configurable timer/PWM (SCTimer), multi-rate timer (MRT), self wake-up timer (WKT), CRC engine, and a single analog comparator - deployed in compact TSSOP16 packaging for cost-sensitive embedded control applications including lighting and motor control.

For engineers reviewing the LPC811M001JDH16J datasheet, LPC811M001JDH16J pinout, LPC811M001JDH16J application, or LPC811M001JDH16J equivalent, key selection considerations include its 14-GPIO count, dual USART support, fixed-pin SWD debug interface, I2C-bus compatibility on true open-drain pins PIO0_10/PIO0_11, and Deep power-down wake-up capability via PIO0_4.

Technical Context

The LPC811M001JDH16J implements an ARM Cortex-M0+ core with single-cycle I/O access and integrated NVIC supporting up to 8 external GPIO interrupts. Its switch matrix enables flexible peripheral pin assignment - including USART0/1, SPI0, I2C0, SCTimer inputs/outputs, and comparator functions - while preserving fixed debug (SWDIO/SWCLK), reset, oscillator (XTALIN/XTALOUT), and wake-up (PIO0_4) pins.

Power management includes Sleep, Deep-sleep, Power-down, and Deep power-down modes with wake-up sources from USART, SPI, I2C, or the dedicated WKT oscillator. The 12 MHz internal RC oscillator (±1.5 %) and PLL allow full-speed operation without external crystals, and the PMU ensures low active and standby current consumption across −40 °C to 105 °C operation.

FAQ

What is the maximum operating frequency of the LPC811M001JDH16J?

The LPC811M001JDH16J 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 plus PLL multiplication, or directly from an external crystal (1–25 MHz) or CLKIN signal. The core's two-stage pipeline and single-cycle I/O ensure deterministic real-time execution at this rate, and the LPC811M001JDH16J maintains full functionality across its −40 °C to 105 °C industrial temperature range.

Does the LPC811M001JDH16J support in-system programming (ISP)?

Yes, the LPC811M001JDH16J supports in-system programming via its built-in ROM bootloader. ISP entry is enabled by holding PIO0_1 LOW during reset for chip revisions 1A and 2A, or PIO0_12 LOW for revision 4C and later - both using the same UART0 (U0_RXD/U0_TXD) interface. The 8 kB on-chip ROM provides validated ISP and IAP APIs, eliminating the need for external programming hardware beyond a simple UART-to-USB bridge for flashing the LPC811M001JDH16J.

Which pins on the LPC811M001JDH16J support true open-drain operation for I2C compliance?

The LPC811M001JDH16J supports full I2C-bus compliance (standard, fast, and fast-plus modes) only on pins PIO0_10 and PIO0_11 - the only true open-drain pins in the TSSOP16 package. These pins provide high-current sink capability and require external pull-up resistors. Assigning I2C0_SDA to PIO0_11 and I2C0_SCL to PIO0_10 through the switch matrix ensures electrical compliance; other pins lack the necessary open-drain structure and must not be used for I2C signaling in production designs involving the LPC811M001JDH16J.

Can the LPC811M001JDH16J wake up from Deep power-down mode using a GPIO pin?

Yes, the LPC811M001JDH16J can wake up from Deep power-down mode using PIO0_4, which is designated as the WAKEUP pin. A LOW-going pulse as short as 50 ns on this pin triggers wake-up and exits Deep power-down. To ensure reliable operation, PIO0_4 must be pulled HIGH externally before entering Deep power-down mode, and no movable peripheral function (e.g., USART, SPI) should be assigned to it - as doing so disables its wake-up capability. This feature enables ultra-low-power sensor polling in battery-operated systems using the LPC811M001JDH16J.

How many general-purpose I/O pins does the LPC811M001JDH16J have, and what configuration options are available?

The LPC811M001JDH16J provides 14 general-purpose I/O pins (PIO0_0 through PIO0_13). Each supports configurable pull-up/pull-down resistors, programmable open-drain mode, input inverter, and glitch filtering - controlled via the IOCON block. Eight of these pins support GPIO interrupt generation with boolean pattern-matching logic. Pins PIO0_10 and PIO0_11 are true open-drain; PIO0_0, PIO0_1, PIO0_2, PIO0_3, and PIO0_4 offer 5 V tolerance in digital mode. All configurations are runtime-adjustable, and the LPC811M001JDH16J retains full I/O flexibility even when peripherals are routed via the switch matrix.
