For engineers reviewing the LPC804M101JDH24J datasheet, LPC804M101JDH24J pinout, LPC804M101JDH24J application, or LPC804M101JDH24J equivalent, this page provides verified technical context, package-specific pin mapping, real-world use cases, and validated alternative options for rapid prototyping and production design-in.

Technical Context

The LPC804M101JDH24J implements an Arm Cortex-M0+ core (r0p1) with single-cycle I/O, NVIC, and SysTick timer, paired with a multilayer AHB matrix and APB peripheral bridge. Its clock system centers on a ±1% trimmed Free Running Oscillator (FRO) at 9/12/15 MHz, supplemented by a 1 MHz low-power oscillator and programmable clock output divider.

Peripherals are routed via a flexible switch matrix enabling dynamic assignment of USART, SPI, I²C, CTIMER, CAPT, and PLU signals to non-power pins. The device supports deep-sleep and deep power-down modes with wake-up on GPIO, USART, SPI, or I²C activity, and includes a self-wake-up timer with external clock input capability on PIO0_11.

FAQ

What is the maximum operating frequency of the LPC804M101JDH24J?

The LPC804M101JDH24J operates at a maximum CPU frequency of 15 MHz using its internal Free Running Oscillator (FRO), which is trimmed to ±1% accuracy across 0 °C to 70 °C. This frequency is fixed and cannot be overclocked; the FRO supports selectable outputs of 9 MHz, 12 MHz, or 15 MHz via configuration registers. External clock sources (e.g., via CLKIN) are supported but do not exceed the 15 MHz core limit.

Does the LPC804M101JDH24J include a DAC, and what is its resolution?

Yes, the LPC804M101JDH24J includes a 10-bit DAC with output on PIO0_19 (DACOUT). It provides monotonic output across its full range and supports buffered voltage-mode operation. The DAC is powered from VDD and referenced to VREFP, enabling precise analog output for sensor calibration, LED dimming, or actuator control without external components.

How many GPIO pins does the LPC804M101JDH24J support in the TSSOP24 package?

The LPC804M101JDH24J in TSSOP24 package supports 21 general-purpose I/O pins (PIO0_0 through PIO0_21, excluding power and debug pins). Five of these (PIO0_2, PIO0_3, PIO0_12, PIO0_18, PIO0_20) provide high-current drive (20 mA), and eight (PIO0_4, PIO0_8, PIO0_9, PIO0_10, PIO0_11, PIO0_13, PIO0_15, PIO0_17) support wake-up from deep power-down mode.

Can the LPC804M101JDH24J operate in deep power-down mode, and how is wake-up achieved?

Yes, the LPC804M101JDH24J supports deep power-down mode with typical current draw <1 µA. Wake-up is achieved via eight dedicated GPIO pins (PIO0_4, PIO0_8–PIO0_11, PIO0_13, PIO0_15, PIO0_17), an external clock on PIO0_11 (WKTCLKIN), or activity on USART, SPI, or I²C peripherals. A LOW-going pulse as short as 50 ns on any enabled wake-up pin exits deep power-down and resumes execution from reset vector.

Is the LPC804M101JDH24J pin-compatible with other LPC804 variants like LPC804M111JDH24?

No, the LPC804M101JDH24J (single-supply TSSOP24) is not pin-compatible with LPC804M111JDH24 (dual-supply TSSOP24), as the latter includes a dedicated VDDIO pin (pin 3) absent in the M101 version. While both share the same TSSOP24 footprint and 24-pin count, VDDIO placement alters power domain routing and invalidates direct substitution without PCB revision.
