Key Features
| Feature | Design Value |
|---|---|
| ARM Cortex-M3 with NVIC | Hardware-accelerated nested interrupt handling ensures sub-12-cycle latency and deterministic response for time-critical events like encoder interrupts or fault signals. |
| GPDMA controller | Eight-channel AHB-based DMA enables zero-CPU-overhead transfers between peripherals (ADC→SRAM, UART→memory, etc.) and supports memory-to-memory moves. |
| Dual PLL architecture | Separate CPU and USB PLLs allow independent clock tuning - e.g., 120 MHz CPU with 48 MHz USB clock - eliminating frequency trade-offs in mixed-speed applications. |
| RTC with Event Recorder | 20-byte battery-backed registers retain system state during power loss; Event Recorder timestamps external events (e.g., emergency stop) with microsecond resolution using RTC clock. |
| Quadrature Encoder Interface (QEI) | Dedicated hardware monitors single external quadrature encoder, providing position, direction, and velocity without CPU polling or timer resource consumption. |
| EMC support | External Memory Controller supports SDRAM (up to 80 MHz), SRAM, ROM, and flash - enables expansion of program/data space beyond on-chip limits for HMI or data-logging applications. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LPC1788FET208,551 | Includes LCD controller and 32-bit EMC bus width; otherwise identical flash/SRAM/peripheral set. | Required for TFT/STN display interfaces; unnecessary if display output is handled externally or not needed. | Select LPC1778FET208,551 when LCD functionality is unused - reduces software footprint and avoids unused peripheral clock gating. |
| LPC1777FBD208,551 | LQFP208 package, no Ethernet MAC, same 512 kB flash/96 kB SRAM/peripherals otherwise. | Suitable for CAN/USB-only industrial controllers where Ethernet PHY adds cost and layout complexity. | Choose LPC1777FBD208,551 for simplified PCB routing and lower assembly cost when Ethernet is not required. |
Compared with LPC1788FET208,551, the LPC1778FET208,551 omits LCD support but retains full Ethernet capability - making it optimal for networked control without display overhead. Versus LPC1777FBD208,551, it trades LQFP ease-of-handling for TFBGA density and adds Ethernet, enabling compact, connected edge devices.

FAQ
What is the maximum operating frequency of the LPC1778FET208,551?
The LPC1778FET208,551 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 by either the internal 12 MHz RC oscillator (±1% accuracy) or an external crystal (1–25 MHz). The flash accelerator ensures near-zero wait-state execution at full speed, maintaining performance without external cache or SRAM.
Does the LPC1778FET208,551 include an Ethernet MAC?
Yes, the LPC1778FET208,551 includes a full Ethernet MAC with MII/RMII interface and associated DMA controller. Unlike the LPC1777 variant, it retains Ethernet capability while omitting the LCD controller. An external PHY is required, and the MAC resides on an independent AHB bus to avoid contention with CPU or USB traffic.
How much SRAM does the LPC1778FET208,551 provide, and how is it organized?
The LPC1778FET208,551 provides 96 kB of total SRAM: 64 kB main SRAM on the CPU's local code/data bus for high-speed access, and two 16 kB peripheral SRAM blocks with separate AHB access paths. This structure enables concurrent CPU execution and DMA transfers (e.g., ADC→peripheral SRAM while CPU processes prior buffer), improving real-time throughput.
What analog peripherals are integrated into the LPC1778FET208,551?
The LPC1778FET208,551 integrates an 8-channel 12-bit ADC with up to 400 kHz conversion rate and a 10-bit DAC with dedicated conversion timer and GPDMA support. The ADC supports multiple result registers and hardware averaging; the DAC includes configurable update triggers and supports audio waveform generation or analog setpoint output in control systems.
Is the LPC1778FET208,551 pin-compatible with other LPC17xx devices?
The LPC1778FET208,551 shares the TFBGA208 package and pinout with LPC1788FET208,551 and LPC1777FBD208,551 (LQFP208), but functional pin compatibility is partial: Ethernet pins are identical, LCD pins are no-connection (NC) on LPC1778, and CAN/USB/UART signals align across the family. Always verify pin function mapping per Table 3 in the datasheet before PCB reuse.
