NXP Semiconductors LPC811M001JDH16FP

Overview

LPC811M001JDH16FP from NXP Semiconductors is a 32-bit ARM Cortex-M0+ microcontroller in TSSOP16 package, operating up to 30 MHz with 8 kB flash and 2 kB SRAM. It integrates a switch-matrix-configurable I/O system, SCTimer/PWM, multi-rate timer, self wake-up timer, CRC engine, and one analog comparator - deployed in lighting control, motor drive, and climate management systems.

For engineers reviewing the LPC811M001JDH16FP datasheet, LPC811M001JDH16FP pinout, LPC811M001JDH16FP application, or LPC811M001JDH16FP equivalent, key selection criteria include its 14 GPIO count, dual USART support, fixed-pin debug interface (SWDIO/SWCLK), true open-drain I2C capability on PIO0_10/PIO0_11, and Deep power-down wake-up via PIO0_4.

Technical Context

The LPC811M001JDH16FP implements an ARM Cortex-M0+ core with single-cycle I/O, NVIC, and Micro Trace Buffer, executing at up to 30 MHz using internal RC (12 MHz ±1.5%) or external crystal (1–25 MHz). Its peripheral architecture centers on a flexible switch matrix enabling dynamic assignment of USART, SPI, SCTimer, and I2C functions to any non-power pin.

Power management includes Sleep, Deep-sleep, Power-down, and Deep power-down modes with wake-up sources including USART activity, SPI, I2C, and dedicated WAKEUP pin (PIO0_4). The comparator supports internal/external references, and the IOCON block enables per-pin configuration of pull-up/down, glitch filtering, input inversion, and hysteresis.

FAQ

What is the maximum operating frequency of the LPC811M001JDH16FP?

The LPC811M001JDH16FP operates at a maximum CPU frequency of 30 MHz. This is achieved using the internal 12 MHz ±1.5% RC oscillator with PLL multiplication, an external crystal (1–25 MHz), or external clock input. The ARM Cortex-M0+ core's two-stage pipeline and single-cycle multiplier ensure deterministic execution at this rate, making the LPC811M001JDH16FP suitable for real-time control tasks such as motor commutation and LED dimming without timing jitter.

Does the LPC811M001JDH16FP support in-system programming (ISP)?

Yes, the LPC811M001JDH16FP supports In-System Programming via its built-in ROM bootloader. ISP entry is triggered by a LOW level on PIO0_1 during reset for chip revisions 1A/2A, or on PIO0_12 for revision 4C and later - both applicable to the TSSOP16 package. The ROM includes validated USART drivers and flash programming routines, enabling field firmware updates without external debug hardware. The LPC811M001JDH16FP also supports In-Application Programming (IAP) for runtime code updates.

How many GPIO pins does the LPC811M001JDH16FP have, and what configuration options are available?

The LPC811M001JDH16FP provides 14 general-purpose I/O pins. Each supports configurable pull-up/pull-down resistors, programmable open-drain mode, input inverter, and glitch filtering via the IOCON block. Four pins deliver 20 mA source current; two (PIO0_10/PIO0_11) provide 20 mA sink in true open-drain mode. All GPIOs are 5 V tolerant in digital mode, and eight support boolean pattern-match interrupt generation - enabling complex wake-up logic without CPU involvement.

Can the LPC811M001JDH16FP wake up from Deep power-down mode, and how is it configured?

Yes, the LPC811M001JDH16FP can wake up from Deep power-down mode via PIO0_4 (WAKEUP pin), which responds to a LOW-going pulse as short as 50 ns. To use this feature, PIO0_4 must be left unassigned to movable functions and externally pulled HIGH before entering Deep power-down. The LPC811M001JDH16FP also supports wake-up from USART, SPI, and I2C activity in Deep-sleep and Power-down modes. The self wake-up timer (WKT) provides additional time-based wake-up capability using the low-power 10 kHz oscillator.

What are the I2C interface capabilities of the LPC811M001JDH16FP?

The LPC811M001JDH16FP includes one I2C-bus interface supporting standard mode (100 kbps), fast mode (400 kbps), and fast-mode plus (1 Mbps). Full compliance requires assignment to the true open-drain pins PIO0_10 (SCL) and PIO0_11 (SDA), which support high-current sinking and I2C Fast-mode Plus configuration via the IOCON register. The I2C function is routed through the switch matrix, allowing flexible pin assignment - but only these two pins guarantee hardware-level open-drain behavior required for bus arbitration and voltage translation.
