Product details

It carries 200K x 8 of on-chip RAM and is ROMless.

180 MHz Cortex-M3 — what it means for throughput

The 180 MHz core speed is at the upper end for Cortex-M3 devices, giving this MCU enough headroom to run a real-time control loop alongside protocol stacks for Ethernet and USB without stalling. The 200 KB RAM supports moderate-sized frame buffers for the LCD controller or packet buffers for Ethernet — enough for a local HMI or a fieldbus gateway, but not for full video frame storage.

Obsolete — sourcing reality for the LPC1850FBD208,551

NXP has marked this part as obsolete.

Connectivity and I/O count

The 142 GPIOs are in the 208-LQFP package.

Supply range is 2.2 V to 3.6 V.

Frequently asked questions

What is the replacement for LPC1850FBD208,551?

No official replacement order code is listed in the available records. The LPC18xx family includes other density and feature variants, but a direct pin-compatible drop-in is not confirmed from this evidence. For a BOM line needing this exact part, sourcing through independent distribution is the current path.

Does LPC1850FBD208,551 have Ethernet and USB?

Yes, the LPC1850FBD208,551 includes Ethernet MAC and USB OTG connectivity, along with CAN, multiple SPI/I²C/UART, and other serial interfaces.

Where can I buy LPC1850FBD208,551?

We source the LPC1850FBD208,551 to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time — submit a request for a firm quote.

What is the package of LPC1850FBD208,551?

The LPC1850FBD208,551 is supplied in a 208-LQFP package (28x28 mm body), surface-mount.
