Product details
Overview
LPC1777FBD208 from NXP Semiconductors is a 32-bit ARM Cortex-M3 microcontroller designed for industrial control and embedded connectivity applications. It operates at up to 120 MHz, integrates 512 kB flash, 96 kB SRAM, dual CAN interfaces, USB Device/Host/OTG with on-chip PHY, five UARTs, and an 8-channel 12-bit ADC - enabling real-time motor control and protocol bridging in compact designs.
For engineers reviewing the LPC1777FBD208 datasheet, LPC1777FBD208 pinout, LPC1777FBD208 application, or LPC1777FBD208 equivalent, this page delivers verified technical context, package-confirmed pin functions, validated alternative parts, and application-specific design value - all grounded in NXP's Rev. 5.5 product data sheet (April 2016).
Technical Context
The LPC1777FBD208 implements a Harvard-architecture ARM Cortex-M3 core with 3-stage pipeline, Memory Protection Unit (MPU), and Nested Vectored Interrupt Controller (NVIC). Its multilayer AHB matrix enables concurrent CPU, USB, Ethernet, and DMA access without arbitration delay unless masters contend for the same slave.
It features a dedicated flash accelerator, dual PLLs (one for CPU, one for USB), and separate RTC power domain supporting battery-backed registers and event recording. Unlike LPC178x variants, LPC1777FBD208 excludes Ethernet MAC but retains full USB 2.0 dual-port capability, LCD controller support, and SD/MMC interface.

Pinout & Package
LPC1777FBD208 uses a plastic low-profile quad flat package (LQFP208) with 208 leads, body size 28 × 28 × 1.4 mm (SOT459-1). All I/O pins are 5 V tolerant except crystal, power, reference, and ADC-input-configured pins.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| P0[0] | CAN1 receiver / UART0/3 TX/RX | Multi-function pin supporting CAN bus physical layer reception or asynchronous serial communication with fractional baud rate generation. |
| P0[22] | CAN1 transmitter / SD_DAT[0] / UART1 RTS | Enables simultaneous CAN node transmission and SD card data transfer, with configurable RS-485 driver enable for industrial serial networks. |
| P0[26] | DAC output / ADC0_IN[3] | Hardware-multiplexed analog terminal: when configured as DAC_OUT, provides 10-bit voltage output; as ADC0_IN[3], accepts 0–VREFP input for sensor signal digitization. |

Key Features
| Feature | Design Value |
|---|---|
| Flash Accelerator + Local Code Bus | Enables zero-wait-state execution at 120 MHz from internal flash, eliminating external memory bottlenecks in time-critical firmware loops. |
| Dedicated RTC Power Domain | Retains 20 bytes of battery-backed registers and continues event timestamping down to 2.1 V supply - critical for power-loss logging and wake-on-event functionality. |
| GPDMA on AHB Matrix | Offloads CPU for transfers between UART/ADC/SSP/I²S peripherals and memory - reduces interrupt overhead and improves throughput in data-intensive protocols like Modbus RTU or CAN FD framing. |
| Pin Function Multiplexing (8 options/pin) | Allows dynamic reconfiguration of I/O roles via IOCON register - simplifies PCB layout by consolidating UART, CAN, I²C, and timer functions onto shared pins without external muxing logic. |
| Windowed Watchdog Timer (WWDT) | Prevents runaway code with strict time-window enforcement and dedicated oscillator - meets IEC 61508 SIL-2 requirements for safety-critical embedded controllers. |
Applications
| Industrial Motor Control | Multi-Protocol Field Gateway |
|---|---|
Use Scenario: Closed-loop servo drive for HVAC compressors using three-phase PWM and quadrature encoder feedback. IC Role / Device Role / Timing Role: LPC1777FBD208 executes FOC algorithms, generates synchronized 6-channel PWM, reads encoder position via QEI, and communicates status over CAN.

IC Role / Device Role / Timing Role: Coordinates real-time event handling: GPIO interrupts detect door forced-open events, RTC timestamps alarms, and USB Host enumerates HID keyboards for admin setup. Use Value: Wake-up Interrupt Controller (WIC) enables sub-10 µA deep-sleep current with instant wake on any GPIO or RTC alarm - extending battery life to >5 years on coin cell. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LPC1787FBD208 | Includes Ethernet MAC (MII/RMII), same flash/SRAM/peripherals otherwise - adds 128 kB EMC bandwidth and PHY interface pins. | Suitable for networked edge nodes requiring TCP/IP stack offload; not required for CAN/USB-only field devices. | Select LPC1787FBD208 only if Ethernet connectivity is mandatory; LPC1777FBD208 reduces layout complexity and cost where wired LAN is absent. |
| LPC1778FBD208 | Identical package and pinout; adds LCD controller (STN/TFT support) and full EMC bus width (32-bit) - no functional difference in CAN/USB/ADC subsystems. | Required for HMI-integrated systems with graphical displays; unnecessary for headless industrial controllers. | Choose LPC1778FBD208 when driving monochrome or color LCD panels; LPC1777FBD208 optimizes cost and power for display-free applications. |
Compared with LPC1787FBD208 and LPC1778FBD208, the LPC1777FBD208 provides identical real-time control capability, peripheral set, and memory configuration - but omits Ethernet and LCD hardware to reduce silicon area, thermal load, and bill-of-materials cost in non-networked, non-display applications.

FAQ
What is the maximum operating frequency of the LPC1777FBD208?
The LPC1777FBD208 operates at up to 120 MHz using its ARM Cortex-M3 core. This frequency is achieved via an on-chip PLL that can be driven from either the main crystal oscillator (1–25 MHz range) or the internal 12 MHz RC oscillator. The flash accelerator ensures zero-wait-state execution at this speed, making the LPC1777FBD208 suitable for demanding real-time control tasks without external memory latency penalties.
Does the LPC1777FBD208 include Ethernet capability?
No, the LPC1777FBD208 does not include an Ethernet MAC. According to NXP's ordering table (Rev. 5.5), Ethernet is explicitly marked "N" for this part number, distinguishing it from LPC178x variants like LPC1787FBD208. However, the LPC1777FBD208 retains full USB 2.0 Device/Host/OTG support with on-chip PHY, dual CAN channels, and five UARTs - making it ideal for non-networked industrial and automotive control applications.
How many analog-to-digital converter channels does the LPC1777FBD208 support?
The LPC1777FBD208 integrates an 8-channel 12-bit ADC (ADC0) with conversion rates up to 400 kHz and multiple result registers. Channels are mapped to P0[23]–P0[30] and P1[31], and all inputs accept 0–VREFP voltage ranges. When configured as ADC inputs, those pins lose 5 V tolerance and must remain within the analog reference voltage limits - a key constraint for mixed-signal system design using the LPC1777FBD208.
What package type is used for the LPC1777FBD208?
The LPC1777FBD208 uses a plastic low-profile quad flat package (LQFP208) with 208 leads and dimensions of 28 × 28 × 1.4 mm (SOT459-1). This package provides full pin compatibility with LPC23xx and LPC24xx families, enabling drop-in migration paths. Pin functions are multiplexed across up to eight options per pin, controlled via the IOCON register - allowing flexible peripheral assignment without board redesign when using the LPC1777FBD208.
Is the LPC1777FBD208 pin-compatible with other LPC17xx devices?
Yes, the LPC1777FBD208 shares identical LQFP208 pinout and function mapping with LPC1778FBD208, LPC1787FBD208, and LPC1788FBD208 - as confirmed in NXP's pin configuration diagrams and Table 3. Differences lie solely in enabled peripherals (e.g., Ethernet, LCD), not pin assignment or electrical characteristics. This allows hardware reuse across variants, with software configuration determining feature activation - a key advantage when scaling functionality using the LPC1777FBD208 in production designs.
