FAQ

What is the maximum operating frequency of the LPC2292FBD144/01?

The LPC2292FBD144/01 achieves a maximum CPU clock frequency of 60 MHz using its on-chip PLL, which has a 100 µs settling time. This frequency is sustained via a 128-bit wide memory interface and accelerator architecture that enables full 32-bit code execution without wait states. The required crystal oscillator operates between 1 MHz and 25 MHz.

Does the LPC2292FBD144/01 support 5 V-tolerant I/O pins?

Yes, the LPC2292FBD144/01 features 5 V-tolerant I/O pads on multiple port pins including P0[0]–P0[31], P1[0]–P1[31], P2[0]–P2[31], and P3[0]–P3[31], with built-in TTL-level hysteresis and 10 ns slew rate control. This allows direct interfacing with 5 V logic without level shifters, simplifying design in mixed-voltage systems.

How many CAN interfaces does the LPC2292FBD144/01 include?

The LPC2292FBD144/01 integrates two independent CAN 2.0B-compliant controllers with advanced acceptance filters. These are exposed as TD2/RD2 (CAN2) and TD1/RD1 (CAN1) on dedicated pins, enabling simultaneous operation on separate CAN buses - ideal for automotive body networks or industrial redundancy schemes.

What boot options are available on the LPC2292FBD144/01?

The LPC2292FBD144/01 uses BOOT0 and BOOT1 pins (P2[26] and P2[27]) to select boot source during reset: 00 = 8-bit memory on CS0, 01 = 16-bit memory on CS0, 10 = 32-bit memory on CS0, 11 = internal flash. This enables flexible firmware deployment across internal flash or external memory devices.

Is the LPC2292FBD144/01 pin-compatible with other LPC229x variants?

Yes, the LPC2292FBD144/01 shares identical LQFP144 pin configuration with LPC2292FBD144/00 and LPC2294HBD144 series devices. However, functional differences exist - e.g., /01 suffix denotes Fast GPIO and SSP support, while /00 lacks these features; LPC2294 adds two more CAN channels and extended temperature range.
