FAQ
What is the operating voltage range for LPC2292FET144,551?
The LPC2292FET144,551 uses dual power supplies: 1.65 V to 1.95 V (1.8 V ±0.15 V) for the CPU core (VDD(1V8)), and 3.0 V to 3.6 V (3.3 V ±10 %) for I/O (VDD(3V3)). All GPIO pins are 5 V tolerant, enabling direct interfacing with legacy 5 V peripherals without level shifters. This separation ensures stable core operation while maintaining backward compatibility.
Does LPC2292FET144,551 support in-system programming (ISP)?
Yes, the LPC2292FET144,551 supports In-System Programming (ISP) and In-Application Programming (IAP) via its on-chip bootloader. It allows single-sector or full-chip flash erase in 400 ms and 256-byte programming in 1 ms, enabling field firmware updates over UART0 without external programmers. The LPC2292FET144,551 bootloader is activated by asserting LOW on P0[14]/DCD1 during reset.
How many CAN interfaces does LPC2292FET144,551 include?
The LPC2292FET144,551 includes two fully independent CAN 2.0B controllers with advanced acceptance filtering, message buffering, and error confinement. These are implemented as dedicated peripheral blocks - not software-emulated - and support bit rates up to 1 Mbit/s. Each CAN controller has dedicated RX/TX pins (e.g., P0[23]/RD2 and P0[24]/TD2 for CAN2), ensuring deterministic real-time performance.
What is the maximum ADC sampling rate of LPC2292FET144,551?
The LPC2292FET144,551 features an eight-channel 10-bit successive approximation register (SAR) ADC with a minimum conversion time of 2.44 µs per sample. At this rate, it achieves up to 409.8 kSPS in single-channel mode. Conversion is triggered by software, timer match, or external event, and results are stored in dedicated registers to minimize interrupt latency - a key capability confirmed in the LPC2292FET144,551 datasheet.
Is LPC2292FET144,551 pin-compatible with other LPC2292 variants?
No - LPC2292FET144,551 uses TFBGA144 packaging, while LPC2292FBD144 uses LQFP144. Though both share identical electrical functionality and pin functions, their physical layouts differ completely: TFBGA144 has 144 solder balls in a 12×12 grid, whereas LQFP144 has 144 gull-wing leads. PCB redesign is required for substitution; the LPC2292FET144,551 cannot be mounted on an LQFP footprint.
