Product details
Overview
LPC1754FBD80,518 from NXP Semiconductors is a 32-bit ARM Cortex-M3 microcontroller operating at up to 100 MHz, featuring 128 kB flash, 32 kB AHB SRAM, 16 kB local SRAM, USB 2.0 Device/Host/OTG interface, one CAN 2.0B channel, and 52 general-purpose I/O pins. It targets industrial control and motor drive applications requiring integrated connectivity and real-time peripherals.
For engineers reviewing the LPC1754FBD80,518 datasheet, LPC1754FBD80,518 pinout, LPC1754FBD80,518 application, or LPC1754FBD80,518 equivalent, key selection criteria include its 100 MHz CPU speed, single-CAN support, absence of Ethernet and I2S, DAC inclusion, and LQFP80 package compatibility with legacy LPC17xx designs.
Technical Context
The LPC1754FBD80,518 implements an ARM Cortex-M3 core with Harvard architecture, 3-stage pipeline, and integrated NVIC and MPU supporting eight memory regions. Its memory subsystem includes 128 kB on-chip flash with zero-wait-state operation at 100 MHz and 48 kB total SRAM (32 kB AHB + 16 kB local), partitioned for CPU, DMA, and peripheral access.
Peripheral interconnect uses a multilayer AHB matrix enabling concurrent CPU, GPDMA, USB, and UART operations without arbitration delay, while dual APB bridges isolate high-throughput timers and ADC from lower-bandwidth I²C/SSP blocks. The device supports four UARTs with fractional baud rate generation, one CAN controller, and a 12-bit ADC with six-channel multiplexing and DMA capability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | ARM Cortex-M3 running at up to 100 MHz - enables deterministic real-time execution with low-latency interrupt handling. |
| Flash Memory | 128 kB on-chip flash - sufficient for medium-complexity firmware with bootloader and application code separation. |
| SRAM | 48 kB total (32 kB AHB + 16 kB local) - supports simultaneous CPU instruction fetch, DMA buffering, and USB packet handling. |
| USB Interface | USB 2.0 full-speed Device/Host/OTG with on-chip PHY and dedicated DMA - eliminates external transceiver need for embedded host or dual-role applications. |
| CAN Channels | 1 × CAN 2.0B controller - provides robust fieldbus communication for industrial automation and motor control networks. |

FAQ
What is the maximum CPU frequency supported by the LPC1754FBD80,518?
The LPC1754FBD80,518 operates at a maximum CPU frequency of 100 MHz. This is achieved using the on-chip PLL driven by the main oscillator, internal RC oscillator, or RTC oscillator. The flash accelerator ensures zero wait states at this speed, enabling deterministic real-time performance without instruction fetch stalls.
Does the LPC1754FBD80,518 include a DAC, and what is its resolution and interface capability?
Yes, the LPC1754FBD80,518 includes a 10-bit Digital-to-Analog Converter (DAC) with dedicated conversion timer and DMA support. It outputs through P0[26] (AOUT), supports continuous waveform generation, and integrates directly with the GPDMA controller to enable buffer-driven audio or calibration signal output without CPU intervention.
How many CAN interfaces does the LPC1754FBD80,518 support, and are they CAN 2.0A or 2.0B compliant?
The LPC1754FBD80,518 supports one CAN 2.0B controller compliant with ISO 11898-1. It handles both standard (11-bit) and extended (29-bit) identifier frames, includes message RAM with configurable acceptance filters, and supports bit rates up to 1 Mbps - meeting requirements for industrial CANopen and J1939 node implementations.
What package type and pin count does the LPC1754FBD80,518 use, and is it compatible with other LPC17xx devices?
The LPC1754FBD80,518 uses an 80-pin LQFP package (12 mm × 12 mm × 1.4 mm, SOT315-1). It shares identical pinout and footprint with LPC1751/52/56/58/59 variants in the same package, enabling drop-in replacement within the LPC175x family for design scalability or cost optimization.
Does the LPC1754FBD80,518 support USB Host functionality, and what peripherals does it require?
Yes, the LPC1754FBD80,518 supports USB 2.0 full-speed Host/Device/OTG functionality with an on-chip PHY. For host mode, it requires only external 1.5 kΩ pull-up resistors on D+ and D−, plus standard USB connectors and power regulation - no external transceiver or hub IC is needed, simplifying host-capable peripheral integration.
