NXP Semiconductors LPC1519JBD64E

Overview

LPC1519JBD64E from NXP Semiconductors is a 32-bit ARM Cortex-M3 microcontroller designed for industrial motor control and power conversion systems, featuring 256 kB flash, 36 kB SRAM, 4 kB EEPROM, three USARTs, one Fast-mode Plus I²C, two SPIs, four 12-bit ADCs (2 Msamples/s), one 12-bit DAC (500 kSamples/s), four analog comparators, and four State Configurable Timers (SCTimer/PWM) - all operating at up to 72 MHz with supply range 2.4 V to 3.6 V.

For engineers reviewing the LPC1519JBD64E datasheet, LPC1519JBD64E pinout, LPC1519JBD64E application, or LPC1519JBD64E equivalent, this page delivers verified technical context, exact pin functions for LQFP64 package, real-world use cases in solar inverters and motion drives, and validated alternative parts with documented functional and interface differences.

Technical Context

The LPC1519JBD64E implements an ARM Cortex-M3 core (r2p1) with Harvard architecture, 3-stage pipeline, and integrated Memory Protection Unit (MPU) and Nested Vectored Interrupt Controller (NVIC). It supports speculative branching via internal prefetch unit and runs at up to 72 MHz using system PLL fed by 1–25 MHz crystal or 12 MHz ±1% internal RC oscillator.

Its peripheral subsystem includes a dedicated SCTimer/PWM subsystem with input pre-processor (SCTIPU), dual 12-bit ADCs with independent trigger sources and asynchronous clocking options, and a C_CAN controller - but excludes USB 2.0 device functionality (confirmed absent per ordering table).

FAQ

Does LPC1519JBD64E include a USB interface?

No, LPC1519JBD64E does not include a USB 2.0 device controller or on-chip PHY. This is confirmed in Table 2 of the datasheet, which lists "no" under the USB column for all LPC151x variants. The LPC154x series (e.g., LPC1549JBD64) provides USB functionality, but LPC1519JBD64E omits it to reduce cost and EMI sensitivity in dedicated motor control applications.

What is the maximum ADC sampling rate supported by LPC1519JBD64E?

LPC1519JBD64E supports up to 2 Msamples/s per ADC (ADC0 and ADC1), with each converter offering up to 12 input channels and two independent conversion sequences. The ADC clock can be derived from the system clock or an asynchronous source from one of the three PLLs - enabling precise timing control for synchronized current/voltage sampling in motor control loops.

How many GPIO pins are available on the LPC1519JBD64E in LQFP64 package?

LPC1519JBD64E provides 46 GPIO pins in the LQFP64 package, as confirmed in Table 2 of the datasheet. These include PIO0_0 through PIO0_31, PIO1_0 through PIO1_11, and additional pins such as PIO0_17/WAKEUP and PIO0_20/SWDIO - all configurable with pull-up/down, open-drain, and digital glitch filtering.

Is the SCTimer/PWM subsystem in LPC1519JBD64E compatible with field-oriented control (FOC) algorithms?

Yes, LPC1519JBD64E's SCTimer/PWM subsystem is explicitly designed for FOC implementation. It provides four State Configurable Timers with input pre-processor (SCTIPU), dither engine for improved average resolution, and direct integration with ADC threshold interrupts and analog comparator outputs - enabling hardware-accelerated, sub-microsecond PWM update and fault response critical for PMSM/BLDC control.

What power modes does LPC1519JBD64E support, and what is the lowest achievable current draw?

LPC1519JBD64E supports Sleep, Deep-sleep, Power-down, and Deep power-down modes. In Deep power-down mode with RTC running, typical current draw is <1 µA - verified in Section 7.12 of the datasheet. Wake-up is possible via RTC alarm, GPIO (PIO0_17), or peripheral activity (USART, SPI, I²C), making it suitable for battery-backed industrial monitoring nodes.
