NXP Semiconductors LPC804M101JHI33E

Overview

LPC804M101JHI33E from NXP Semiconductors is an Arm Cortex-M0+ 32-bit microcontroller operating at up to 15 MHz, featuring 32 KB flash, 4 KB SRAM, a 12-bit ADC (480 kS/s), 10-bit DAC, and Capacitive Touch Interface - deployed in sensor gateways, portable wearables, and industrial control nodes where low-power mixed-signal integration is critical.

For engineers reviewing the LPC804M101JHI33E datasheet, LPC804M101JHI33E pinout, LPC804M101JHI33E application, or LPC804M101JHI33E equivalent, this page delivers verified package mapping (HVQFN33), validated peripheral configuration (switch-matrix I/O, PLU, MRT), confirmed power modes (deep-sleep/wake-up on GPIO/USART/SPI/I2C), and real-world timing constraints (FRO ±1% over 0–70°C).

Technical Context

The LPC804M101JHI33E integrates an Arm Cortex-M0+ r0p1 core with single-cycle I/O and NVIC, coupled to a multilayer AHB matrix and APB peripherals. Its clock system centers on a trimmable Free Running Oscillator (9/12/15 MHz, ±1% accuracy) and supports fractional baud rate generation for dual USARTs.

Analog subsystem includes a 12-bit ADC with two independent sequences and 480 kS/s max sample rate, a 10-bit DAC (PIO0_19), and a 5-input analog comparator with internal/external reference selection. Digital flexibility is enabled by the switch matrix (reassigning I2C/USART/SPI/CapTouch to non-power pins) and Programmable Logic Unit (PLU) for combinatorial/sequential logic.

Key Specifications

Pinout & Package

HVQFN33 package (5 mm × 5 mm × 0.85 mm, thermal pad), 33-terminal layout with exposed thermal pad (pin 33 = VSS). Pin functions are configurable via switch matrix except fixed roles (e.g., SWDIO, RESET, VDD, VSS, VREFP).

FAQ

What is the maximum operating frequency of the LPC804M101JHI33E?

The LPC804M101JHI33E operates at a maximum CPU frequency of 15 MHz, delivered by its internal Free Running Oscillator (FRO) trimmed to ±1% accuracy across 0–70°C. This frequency is fixed and not user-adjustable beyond the three FRO output options (9/12/15 MHz), ensuring timing predictability in real-time control loops without external crystal dependency.

Does the LPC804M101JHI33E support in-system programming (ISP)?

Yes, the LPC804M101JHI33E supports In-System Programming (ISP) through its USART interface, enabled by the on-chip ROM bootloader. This allows firmware updates in the field without requiring a debugger - critical for remote sensor nodes and maintenance-free wearable devices where physical access is limited.

How many GPIO pins are available on the LPC804M101JHI33E in HVQFN33 package?

The LPC804M101JHI33E provides up to 30 general-purpose I/O pins (PIO0_0 to PIO0_30) in the HVQFN33 package. All are configurable via the switch matrix for digital I/O, analog input, or peripheral functions - with five high-drive (20 mA) outputs and eight dedicated deep power-down wake-up pins confirmed in the datasheet.

What analog peripherals does the LPC804M101JHI33E include?

The LPC804M101JHI33E integrates a 12-bit ADC with up to 12 input channels and 480 kS/s sampling, a 10-bit DAC on PIO0_19, and a 5-input analog comparator with selectable internal/external reference. These are fully functional in the HVQFN33 variant and require no external components for basic ratiometric or threshold-based analog measurement.

Is the LPC804M101JHI33E pin-compatible with other LPC804 variants?

No - the LPC804M101JHI33E uses the HVQFN33 package (33 terminals), while other variants use TSSOP20, TSSOP24, or WLCSP20 packages with different pin counts and layouts. Pin assignments, thermal pad presence, and mechanical dimensions are not interchangeable; PCB redesign is required when migrating to or from LPC804M101JHI33E.
