Surface-mount, fine-pitch — standard for two-layer PCB routing. The 48-pin count is a common sweet spot: enough I/O for a keypad, LCD, and a few sensors, without blowing the board budget on a larger QFP.
The LPC1345FBD48,151 runs at 72 MHz with 32 KB Flash and 10 KB RAM, while the LPC1343 typically runs at a lower speed with less memory. Pin compatibility varies by package — verify the specific LPC1343 variant against the 48-LQFP footprint before substituting.
Yes, it is ROHS3 Compliant, meeting the latest EU RoHS directive requirements.
The pinout is defined in the NXP LPC1345 datasheet. The 48-LQFP package allocates 40 general-purpose I/O plus dedicated power, ground, and oscillator pins. Request the datasheet with your RFQ for the full pin assignment table.
