Product details
Overview
LPC1548JBD100E from NXP Semiconductors is a 32-bit ARM Cortex-M3 microcontroller designed for industrial motor control and digital power applications, operating at up to 72 MHz with 128 kB flash, 20 kB SRAM, 4 kB EEPROM, dual 12-bit ADCs (2 Msamples/s), one 12-bit DAC (500 kSamples/s), C_CAN, USB 2.0 full-speed device interface, and four State Configurable Timers (SCTimer/PWM) supporting advanced PWM generation and analog feedback integration.
For engineers reviewing the LPC1548JBD100E datasheet, LPC1548JBD100E pinout, LPC1548JBD100E application, or LPC1548JBD100E equivalent, key selection considerations include its LQFP100 package with 76 GPIOs, integrated analog comparators with SCTimer coupling, RTC with independent power domain, and support for Deep power-down wake-up via USB/USART/SPI/I2C activity or RTC alarm - critical for energy-constrained embedded systems.
Technical Context
The LPC1548JBD100E implements an ARM Cortex-M3 core (r2p1) with Harvard architecture, 3-stage pipeline, and internal prefetch unit enabling speculative branching. It integrates a dedicated Power Management Unit (PMU) supporting Sleep, Deep-sleep, Power-down, and Deep power-down modes with configurable wake-up sources including RTC alarm, USB activity, and peripheral interrupts.
Its analog subsystem features two independent 12-bit ADCs with up to 12 channels each, asynchronous clocking from PLLs, dual conversion sequences, and direct routing of comparator outputs and temperature sensor signals to SCTimer/PWM modules - enabling closed-loop motor control without CPU intervention.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LPC1549JBD100 | 256 kB flash, 36 kB SRAM, same peripherals - adds 128 kB flash and 16 kB SRAM over LPC1548JBD100. | Required for larger firmware images (e.g., dual-bank OTA updates) or complex control stacks with floating-point math libraries. | Select when firmware size exceeds 128 kB or additional RAM is needed for real-time data buffering. |
| LPC1518JBD100 | No USB interface, identical memory and analog/peripheral configuration otherwise - removes USB 2.0 FS device controller and PHY. | Suitable for cost-sensitive industrial controls where USB connectivity is unnecessary and CAN/USART suffice for diagnostics. | Choose for CAN-centric applications (e.g., factory floor HMIs) where USB footprint and BOM cost must be minimized. |
Compared with LPC1549JBD100, LPC1548JBD100 trades flash/SRAM capacity for lower cost and power; compared with LPC1518JBD100, it adds USB 2.0 FS capability essential for field firmware updates and host-connected commissioning tools - making it optimal for digitally enabled power conversion systems requiring both performance headroom and serviceability.

FAQ
What is the maximum operating frequency of the LPC1548JBD100E?
The LPC1548JBD100E operates at a maximum CPU frequency of 72 MHz, achieved via its ARM Cortex-M3 core with system PLL driven by either the internal 12 MHz RC oscillator (trimmed to ±1 % accuracy) or an external crystal oscillator (1–25 MHz). This frequency enables deterministic execution of real-time control loops with sub-microsecond interrupt latency.
Does the LPC1548JBD100E support USB device functionality?
Yes, the LPC1548JBD100E integrates a full-speed USB 2.0 device controller with an on-chip PHY, supporting USB device enumeration, CDC ACM class for virtual COM port, and DFU (Device Firmware Upgrade) mode. USB_DP and USB_DM pins are dedicated and require only series resistors and ESD protection per USB specification.
How many analog-to-digital converters does the LPC1548JBD100E include?
The LPC1548JBD100E includes two independent 12-bit analog-to-digital converters (ADC0 and ADC1), each supporting up to 12 input channels and sample rates of up to 2 Msamples/s. Both ADCs feature asynchronous clocking from dedicated PLLs, dual conversion sequences, and hardware trigger routing to SCTimer/PWM modules for synchronized sampling.
What low-power modes are available on the LPC1548JBD100E?
The LPC1548JBD100E supports four reduced-power modes: Sleep, Deep-sleep, Power-down, and Deep power-down. Wake-up sources include RTC alarm, USB/USART/SPI/I2C activity, GPIO interrupts, and comparator outputs. In Deep power-down mode, current consumption drops below 1 μA while retaining RTC operation and wake-up capability.
Is the LPC1548JBD100E pin-compatible with other LPC15xx devices in LQFP100 package?
Yes, the LPC1548JBD100E shares identical pinout and package (LQFP100, SOT407-1) with LPC1549JBD100, LPC1518JBD100, and LPC1519JBD100. All share the same pin assignments for power, reset, debug, USB, and peripheral interfaces - enabling hardware reuse across firmware variants with different flash/RAM or USB inclusion.
