Frequently asked questions
Does the LPC1822JBD144E need an external crystal for USB OTG timing accuracy?
Yes. The internal oscillator does not meet USB OTG timing accuracy at 180MHz. For USB OTG designs, especially in 105°C ambient environments, an external crystal is required — the internal oscillator is acceptable for UART and IrDA links only where baud error tolerance is wider.
Is the LPC1822JBD144E pin-compatible with the LPC1769 drop-in footprint?
No. The motor control PWM block on the LPC1822 is a dedicated peripheral with different timer routing than the standard PWM on the LPC1769 — firmware needs a full peripheral port, not a parameter patch. Confirm the full pinout match before assuming drop-in compatibility.
How does the LPC1822JBD144E handle the -40°C to 105°C temperature range for factory-floor applications?
The -40°C to 105°C rating covers the ambient extremes typical in industrial enclosures and factory-floor zones. The 2.2–3.6V supply range sits cleanly on a 3.3V logic rail, which simplifies power architecture for industrial control modules running in thermally variable environments.
