FAQ

What is the maximum operating frequency of the LPC2368FBD100K?

The LPC2368FBD100K operates at a maximum CPU clock frequency of 72 MHz, achieved via its on-chip PLL that accepts input from the main oscillator (1–24 MHz crystal), internal 4 MHz RC oscillator, or RTC oscillator. This frequency is sustained across the full industrial temperature range (−40 °C to +85 °C) and supports deterministic real-time execution for industrial control tasks.

Does the LPC2368FBD100K include an integrated USB physical layer?

Yes, the LPC2368FBD100K includes a fully integrated USB 2.0 full-speed (12 Mbps) physical layer (PHY) and 4 kB of on-chip endpoint RAM. This eliminates the need for an external USB transceiver and enables direct connection to USB connectors with only standard ESD protection components - confirmed in Section 2 "Features and benefits" and Table 2 "Ordering options" of the official datasheet.

How many CAN interfaces does the LPC2368FBD100K support?

The LPC2368FBD100K supports two independent CAN 2.0B controllers, as explicitly stated in the General Description and verified in Table 2 "Ordering options", which lists "CAN" as "2" for this part number. Both controllers are accessible via Port 0 and Port 1 pins (e.g., RD1/TD1 and RD2/TD2) and operate concurrently with Ethernet and USB.

What type of package is used for the LPC2368FBD100K?

The LPC2368FBD100K uses a plastic low-profile quad flat package (LQFP100) with 100 leads and dimensions of 14 × 14 × 1.4 mm (package code SOT407-1). This is confirmed in Table 1 "Ordering information" and applies specifically to the "FBD" suffix variant, distinguishing it from the TFBGA100 ("FET") version.

Is the LPC2368FBD100K compatible with the ARM JTAG debug interface?

Yes, the LPC2368FBD100K provides full ARM-standard JTAG test/debug interface (TCK, TMS, TDI, TDO, TRST, RTCK) compliant with existing ARM development tools. It also includes an Emulation Trace Module for real-time instruction and data trace, as documented in Section 2 "Features and benefits" and Figure 1 "Block diagram".
