Product Overview

LPC1788FBD208K is a flagship 32-bit microcontroller (MCU) from NXP’s LPC178x Series, based on the high-performance ARM® Cortex-M3 core, designed for embedded applications requiring high integration and low power consumption. This product supports a maximum clock frequency of 120 MHz, integrates 512 KB large-capacity Flash, 96 KB SRAM, and 4032-byte EEPROM, and is equipped with full-scenario peripherals such as Ethernet, USB 2.0 OTG, and LCD controller. Adopting a 208-pin LQFP package, it operates within a voltage range of 2.4-3.6 V and a temperature range of -40°C to 85°C, perfectly suitable for mid-to-high-end scenarios such as industrial control, communication equipment, and consumer electronics. As the core model of LPC1788FBD208K, its excellent performance, rich interfaces, and reliable stability make it an ideal replacement for the LPC23xx/24xx series.

Key Features

• High-Performance Core Architecture：Features a 120 MHz ARM® Cortex-M3 core with 3-stage pipeline and Harvard architecture, built-in Nested Vectored Interrupt Controller (NVIC) with low interrupt latency, and higher computational efficiency than equivalent ARM7 cores.
• Large-Capacity Storage Configuration：Integrates 512 KB programmable Flash (100k erase/write cycles), 96 KB high-speed SRAM (including 64 KB local bus SRAM + two 16 KB peripheral SRAMs), and 4032-byte EEPROM, meeting the storage needs of complex programs and data.
• Full-Featured Peripheral Integration：Covers 10/100 Mbps Ethernet MAC, USB 2.0 dual-port OTG/Host/Device, LCD controller (supports 1024×768 resolution), 8-channel 12-bit ADC, 10-bit DAC, as well as 5 UARTs, 3 SSPs, 3 I2Cs, 2 CANs and other communication interfaces.
• Flexible Low-Power Design：Supports four low-power modes (Sleep/Deep-sleep/Power-down/Deep power-down) with a typical power consumption of 1.3 μA in Deep power-down mode. Combined with peripheral clock gating, it balances performance and energy consumption.
• High Reliability and Compatibility：Operates within a temperature range of -40°C to 85°C, with ESD protection up to ±4000 V (HBM), supports Code Read Protection (CRP), and is pin-compatible with the LPC23xx/24xx series, reducing migration costs.

Technical Specifications

Typical Applications

• Industrial Control：Suitable for programmable logic controllers (PLCs), motor drives, industrial gateways. The 120 MHz core frequency and rich PWM/timer resources ensure control accuracy, while Ethernet and multi-serial ports support device networking and data interaction. The wide-temperature design of LPC1788FBD208K adapts to harsh industrial environments.
• Communication Equipment：Used in point-of-sale terminals, multi-protocol bridges, web servers. The Ethernet and USB OTG dual interfaces meet wired communication and peripheral expansion needs, and large-capacity storage can cache complex communication protocol stacks. Low-power mode extends device battery life.
• Consumer Electronics：Applicable to smart printers, audio decoders, fitness equipment. The LCD controller supports high-definition display interfaces, and multi-serial ports and SSP interfaces are compatible with peripheral modules. High integration reduces BOM costs and PCB space.
• Automotive Aftermarket：Fits in-vehicle GPS terminals, car alarms, fleet monitors. The wide-voltage design is compatible with in-vehicle power supplies, stable communication interfaces ensure reliable data transmission, and the compact package adapts to limited in-vehicle space.
• Medical & IoT：Used in medical scanning equipment, IoT gateways, smart monitoring terminals. High reliability and low power consumption meet long-term operation needs, and rich analog and digital peripherals support sensor data collection and remote communication.
