NXP Semiconductors LPC1519JBD100E

Overview

LPC1519JBD100 from NXP Semiconductors is a 32-bit ARM Cortex-M3 microcontroller designed for industrial motor control and power conversion systems. It operates at up to 72 MHz, integrates 256 kB flash, 36 kB SRAM, and 4 kB EEPROM, and features dual 12-bit ADCs (2 Msamples/s), one 12-bit DAC, four analog comparators, and four State Configurable Timers (SCTimer/PWM) with input pre-processing - enabling precise real-time motor feedback and PWM generation in solar inverters and motion drives.

For engineers reviewing the LPC1519JBD100 datasheet, LPC1519JBD100 pinout, LPC1519JBD100 application, or LPC1519JBD100 equivalent, key selection considerations include its LQFP100 package (100-pin, 14 × 14 mm), absence of USB peripheral (vs. LPC1549), C_CAN interface, three USARTs with RS-485 support, and RTC with independent power domain for wake-up from Deep power-down mode.

Technical Context

The LPC1519JBD100 implements an ARM Cortex-M3 core (r2p1) with Harvard architecture, 3-stage pipeline, and integrated NVIC, MPU, and system tick timer. Its clock system includes a 12 MHz ±1 % internal RC oscillator, crystal oscillator (1–25 MHz), and three PLLs - one for CPU, one for USB (not used in this variant), and one dedicated to SCTimer/PWM subsystem timing.

Peripheral interconnect uses a multi-layer AHB matrix with APB bridges, switch matrix (SWM), input multiplexer (INPUT MUX), and SCT Input Pre-processor Unit (SCTIPU). This enables flexible pin assignment, concurrent peripheral triggering (e.g., ADC threshold interrupts directly feeding SCTimer), and deterministic low-latency event handling for closed-loop motor control.

FAQ

Does LPC1519JBD100 support USB functionality?

No, LPC1519JBD100 does not include a USB controller or on-chip PHY. This distinguishes it from the LPC1549JBD100 variant, which integrates full-speed USB 2.0 device capability. The LPC1519JBD100 retains all other core peripherals - including C_CAN, three USARTs, dual ADCs, and SCTimer subsystem - making it optimized for non-USB industrial control applications where EMI sensitivity and cost must be minimized.

What is the maximum ADC sampling rate supported by LPC1519JBD100?

The LPC1519JBD100 supports up to 2 Msamples/s per ADC (ADC0 and ADC1), with each ADC offering up to 12 input channels and two independent conversion sequences. The ADC conversion clock can be derived from the system clock or an asynchronous clock from one of the three PLLs, enabling precise timing control for synchronized sampling across multiple analog signals in motor control applications.

How many SCTimer/PWM outputs does LPC1519JBD100 provide?

LPC1519JBD100 provides up to 28 total PWM outputs across its four State Configurable Timers (SCT0–SCT3). These outputs support configurable polarity, dead-time insertion, and hardware dithering for improved average resolution. Each SCTimer also accepts direct inputs from analog comparators and ADC threshold events, enabling responsive, event-driven motor control without CPU intervention.

Is LPC1519JBD100 pin-compatible with other LPC15xx variants in LQFP100 package?

Yes, LPC1519JBD100 shares identical LQFP100 pinout (SOT407-1) and footprint with LPC1549JBD100, LPC1548JBD100, and LPC1518JBD100. All share the same mechanical dimensions, power/ground pin locations, and fixed-function pin assignments (e.g., SWD, reset, crystal, ADC, DAC). Functional differences (e.g., USB presence) do not affect PCB layout compatibility.

What debug interface does LPC1519JBD100 use, and what features does it support?

LPC1519JBD100 uses Serial Wire Debug (SWD) with default SWCLK and SWDIO on pins 63 and 69 respectively. It supports four hardware breakpoints and two watchpoints, system tick timer, and Memory Protection Unit (MPU) debugging. SWD enables full JTAG-equivalent debug access with fewer pins than traditional JTAG, reducing board routing complexity while maintaining robust firmware validation and real-time trace capability for the LPC1519JBD100.
