Product details

120 MHz Cortex-M3 with full peripheral set

The NXP LPC1769FBD100,551 is a 32-bit ARM Cortex-M3 MCU running at 120 MHz, with 512 KB of Flash and 64 KB of RAM. The 70 GPIOs and the 8-channel 12-bit ADC plus a 10-bit DAC cover mixed-signal control loops without an external converter. Operating from 2.4 V to 3.6 V over the industrial -40°C to 85°C range, it fits outdoor telecom cabinets and factory-floor enclosures.

The 512 KB program memory is sized for a full TCP/IP stack plus application code without external Flash. The Ethernet MAC (with dedicated DMA) and USB OTG controller eliminate the need for separate PHY companion chips in many designs.

Frequently asked questions

Does LPC1769FBD100 have Ethernet and USB OTG?

Yes, the LPC1769FBD100,551 includes both Ethernet and USB OTG connectivity, along with CAN, I²C, SPI, UART, SSI, Microwire, and IrDA.

What is the difference between LPC1769 and LPC1768?

Both share the same 512 KB Flash, 64 KB RAM, 100-LQFP package, and Cortex-M3 core at 120 MHz. The LPC1769 adds Ethernet MAC and USB OTG; the LPC1768 omits those two peripherals. If your design needs wired networking or host/device USB, the LPC1769 is the correct choice.

What is LPC1769FBD100,551's listed speed?

The core runs at 120 MHz, the highest speed grade in the LPC17xx series.
