NXP Semiconductors LPC804M101JDH20FP

Overview

LPC804M101JDH20FP from NXP Semiconductors is a 32-bit Arm Cortex-M0+ microcontroller operating at up to 15 MHz, featuring 32 KB flash, 4 KB SRAM, a 12-bit ADC (up to 480 kS/s), a 10-bit DAC, and a Capacitive Touch Interface - deployed in sensor gateways and portable wearables requiring compact, low-power control with analog sensing and human interface capability.

For engineers reviewing the LPC804M101JDH20FP datasheet, LPC804M101JDH20FP pinout, LPC804M101JDH20FP application, or LPC804M101JDH20FP equivalent, key selection criteria include its TSSOP20 package with 17 GPIOs, dual I²C/USART interfaces, switch-matrix–configured peripherals, and support for deep-sleep wake-up on USART/SPI/I²C activity - critical for battery-constrained edge nodes.

Technical Context

The LPC804M101JDH20FP integrates an Arm Cortex-M0+ core (r0p1) with single-cycle I/O and NVIC, coupled to a multilayer AHB matrix and APB-peripheral bridge. Its clock system centers on a ±1% trimmed Free Running Oscillator (9/12/15 MHz), supplemented by a 1 MHz low-power oscillator and programmable clock output divider.

Analog subsystem includes a 12-bit ADC with two independent sequences and 12-channel input mux, a 5-input analog comparator with internal/external reference, and a 10-bit DAC - all accessible via the flexible switch matrix. Digital logic extends to a Programmable Logic Unit (PLU) for small state machines and a pattern-match engine for GPIO-triggered interrupts.

FAQ

What is the maximum operating frequency of the LPC804M101JDH20FP?

The LPC804M101JDH20FP operates at a maximum CPU frequency of 15 MHz, derived from its internally trimmed Free Running Oscillator (FRO) with selectable 9 MHz, 12 MHz, or 15 MHz outputs. This frequency is guaranteed across the full industrial temperature range (-40°C to +105°C) and supply voltage (1.71–3.6 V), with ±1% accuracy over voltage and temperature - enabling deterministic real-time execution without external crystal dependency.

Does the LPC804M101JDH20FP include a DAC, and what is its resolution?

Yes, the LPC804M101JDH20FP includes a 10-bit DAC with one output channel (DACOUT on PIO0_19). While the DAC is present in the LPC804 family, the LPC804M101JDH20FP variant - packaged in TSSOP20 - does not expose the DACOUT pin; this function is only available on TSSOP24 and HVQFN33 packages. Therefore, the DAC is not usable on the LPC804M101JDH20FP in its current pinout configuration.

How many GPIO pins are available on the LPC804M101JDH20FP in the TSSOP20 package?

The LPC804M101JDH20FP in TSSOP20 package provides 17 general-purpose I/O pins (PIO0_0 through PIO0_17, excluding power/ground pins). All 17 support configurable pull-up/pull-down, open-drain mode, input inversion, and glitch filtering. Five of these (PIO0_2, PIO0_3, PIO0_12, PIO0_18, PIO0_20) offer high-current drive capability (20 mA source), and eight (PIO0_4, PIO0_8, PIO0_9, PIO0_10, PIO0_11, PIO0_13, PIO0_15, PIO0_17) can trigger wake-up from deep power-down mode.

Can the LPC804M101JDH20FP support in-system programming (ISP)?

Yes, the LPC804M101JDH20FP supports in-system programming (ISP) via its USART interface using the on-chip ROM bootloader. Entry into ISP mode is triggered by holding PIO0_12 LOW during reset. The device accepts firmware updates over UART without requiring a debugger, enabling field upgrades and manufacturing programming - a capability confirmed in the official NXP LPC804 user manual and datasheet Rev. 2.1.

What analog peripherals are functional on the LPC804M101JDH20FP TSSOP20 variant?

The LPC804M101JDH20FP TSSOP20 variant supports a full 12-bit ADC with up to 12 input channels (ADC_0 through ADC_11), a 5-input analog comparator (ACMP_I1 through ACMP_I5), and VREFP reference input - all accessible via dedicated pins in the TSSOP20 pinout. However, the 10-bit DAC (DACOUT) and ACMP_I5 are not routed to pins in this package; ACMP_I5 appears only on TSSOP24/HVQFN33 variants, and DACOUT is unavailable in TSSOP20.
