Technical Context

The LPC844M201JBD48E implements an Arm Cortex-M0+ core (r0p1) with single-cycle I/O, NVIC, and Micro Trace Buffer, paired with a flexible switch matrix enabling dynamic peripheral-to-pin routing for UART, SPI, I2C, SCTimer/PWM, and ADC/DAC functions.

Its clock system integrates a factory-trimmed Free Running Oscillator (±1% over 0–70 °C) with selectable 18/24/30 MHz outputs, PLL for CPU scaling, and low-power oscillators for deep power-down wake-up via WKTCLKIN or RESET pins - all managed through the PMU and DPDCTRL register.

FAQ

What is the maximum operating frequency and core architecture of the LPC844M201JBD48E?

The LPC844M201JBD48E features an Arm Cortex-M0+ processor core (revision r0p1) with a maximum CPU frequency of 30 MHz. It includes a single-cycle multiplier and fast single-cycle I/O port, delivering deterministic real-time performance with low power consumption. The core is supported by an integrated Nested Vectored Interrupt Controller (NVIC) and Micro Trace Buffer (MTB) for debug visibility.

Does the LPC844M201JBD48E support in-application programming (IAP) and what interfaces enable it?

Yes, the LPC844M201JBD48E supports Flash In-Application Programming (IAP) via its on-chip ROM API. Programming can be performed through USART, SPI, or I2C interfaces using the ISP (In-System Programming) protocol. This allows field firmware updates without requiring a dedicated debugger, leveraging standard communication peripherals already present in the target system design.

How many GPIO pins are available on the LPC844M201JBD48E and what advanced I/O features do they support?

The LPC844M201JBD48E provides 42 general-purpose I/O pins in its LQFP48 package. These support configurable pull-up/pull-down resistors, programmable open-drain mode, input inverters, digital filtering, and independent bit set/clear/toggle control. Four pins offer 20 mA high-current source drive, and two are true open-drain with 20 mA sink capability - ideal for driving LEDs or interfacing with I2C Fast-mode Plus buses.

What analog peripherals are integrated into the LPC844M201JBD48E and what are their key specifications?

The LPC844M201JBD48E integrates a 12-bit ADC with up to 12 input channels and 1.2 Msamples/s maximum sample rate, two 10-bit DACs (DACOUT_0 and DACOUT_1), and a five-input analog comparator with internal/external reference selection. The ADC supports dual independent conversion sequences, while the DAC outputs are routed to dedicated pins (PIO0_17 and PIO0_29) for direct analog actuation.

Can the LPC844M201JBD48E wake from deep power-down mode, and if so, which pins or mechanisms support this?

Yes, the LPC844M201JBD48E can wake from deep power-down mode via three mechanisms: the dedicated WAKEUP pin (PIO0_4), the RESET pin (PIO0_5), or the self-wake-up timer (WKT) clocked by FRO, low-power oscillator, or external WKTCLKIN (PIO0_28). A LOW pulse ≥50 ns on PIO0_4 or PIO0_5 triggers wake-up; WKT enables autonomous periodic wake-up without external stimulus - critical for battery-powered sensor polling.
