Frequently asked questions
Does the LPC1788's internal oscillator meet USB OTG full-speed timing requirements, or does a design need an external crystal?
The oscillator type is listed as internal. USB full-speed operation requires ±0.25% clock accuracy, which the internal RC may not meet depending on the specific device revision and temperature. Designs targeting certified USB OTG compliance should verify the internal oscillator specification against the NXP datasheet — if the internal RC accuracy is insufficient, an external crystal is required and its load capacitance spec is datasheet-only.
What peripheral interfaces does the LPC1788FBD208,551 expose for an industrial control design?
The part includes Ethernet MAC, dual CAN, USB OTG, SPI, SSP, SSI, I²C, UART/USART, Microwire, memory card interface, LCD controller, motor-control PWM, 8-channel 12-bit ADC, and 1-channel 10-bit DAC across 165 programmable I/O — one of the densest peripheral stacks in the LPC17xx family for compact PLC and networked drive applications.
