Product details
Overview
LPC2292FBD144,551 from NXP Semiconductors is a 16/32-bit ARM7TDMI-S microcontroller in LQFP144 package with 256 kB flash, 16 kB SRAM, dual CAN interfaces, 8-channel 10-bit ADC (2.44 µs conversion), and 60 MHz max CPU clock-designed for automotive control units requiring real-time fault-tolerant communication and mixed-signal processing.
For engineers reviewing the LPC2292FBD144,551 datasheet, LPC2292FBD144,551 pinout, LPC2292FBD144,551 application, or LPC2292FBD144,551 equivalent, key selection criteria include dual-CAN timing compliance, 5 V-tolerant GPIO count (up to 112 pins), external memory interface support (4 banks, up to 16 MB each), and embedded trace/debug capability via EmbeddedICE-RT and ETM.
Technical Context
The LPC2292FBD144,551 implements an ARM7TDMI-S core with JTAG debug interface (TRST/TCK/TMS/TDO/TDI), EmbeddedICE-RT real-time emulation, and Embedded Trace Macrocell (ETM) for instruction-level tracing. Its memory subsystem includes a 128-bit wide flash interface with accelerator enabling full 60 MHz operation in 32-bit mode.
Peripheral integration includes two UARTs with fractional baud rate generators and hardware flow control, buffered SSP supporting SPI/SSI/Microwire, Fast I²C-bus (400 kbit/s), two 32-bit timers (each with four capture/compare channels), six-channel PWM, RTC, watchdog, and vectored interrupt controller (VIC) with configurable priorities-optimized for deterministic response in safety-critical industrial nodes.

| Diversified Code Read Protection | Three CRP levels (CRP1–CRP3) allow graded firmware security: disable debug, prevent flash read, or lock ISP entirely |
Applications
| Automotive Body Control Module | Industrial CAN Gateway |
|---|---|
Use Scenario: Centralized control of door locks, lighting, wipers, and HVAC using distributed CAN sensors and actuators. IC Role / Device Role / Timing Role: Main MCU executing real-time task scheduler, dual-CAN message routing, and analog sensor acquisition (e.g., temperature, voltage monitoring). Use Value: Dual CAN controllers eliminate external bridge IC; 5 V-tolerant GPIO simplify direct connection to automotive 12 V systems via level-shifting resistors. | Use Scenario: Protocol translation between CANopen fieldbus and Modbus RTU over RS-485 in factory automation. IC Role / Device Role / Timing Role: Bridge processor managing concurrent CAN frame reception/transmission and UART-based serial protocol framing. Use Value: Hardware UART flow control and fractional baud rate ensure reliable Modbus timing; external memory interface supports large protocol stack buffers. |
| Medical Infusion Pump Controller | Fault-Tolerant Maintenance Bus Node |
Use Scenario: Closed-loop delivery control with pressure sensing, motor drive, and safety interlock monitoring. IC Role / Device Role / Timing Role: Safety-critical real-time controller acquiring ADC inputs (pressure, current), generating PWM for stepper drivers, and validating watchdog timeouts. Use Value: Embedded trace capability enables post-failure forensic analysis; dedicated ADC result registers guarantee deterministic sampling jitter below 1 µs. | Use Scenario: Redundant diagnostic node monitoring power supply health, thermal margins, and communication integrity across rail signaling equipment. IC Role / Device Role / Timing Role: Standby monitor executing periodic self-tests, CAN heartbeat validation, and non-volatile event logging to internal flash. Use Value: Power-down mode with external interrupt wake-up (EINT0–EINT3) achieves <10 µA standby current; CRP3 prevents unauthorized firmware modification. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LPC2294HBD144 | 4 CAN channels, extended temperature range (−40 °C to +125 °C), no Fast GPIO/SSP enhancements | Suitable for engine control units requiring additional CAN bus redundancy and higher ambient operating temperature | Select when >2 CAN buses or extended temp grade is mandatory; verify absence of Fast GPIO does not impact timing-critical I/O |
| LPC2368FBD100 | ARM7TDMI-S core, 512 kB flash, 96 kB RAM, USB 2.0 device, no CAN, 100-pin LQFP | Targeted at USB-connected HMI or data logger applications where CAN is unnecessary but larger code space and USB host/device is required | Choose when USB connectivity or increased memory is prioritized over CAN; note pinout and peripheral register map differences require PCB redesign |
Compared with LPC2294HBD144, the LPC2292FBD144,551 trades one CAN channel and extended temperature rating for enhanced I/O speed and serial peripheral features; versus LPC2368FBD100, it retains dual CAN and 5 V-tolerant I/O at the cost of USB and larger memory-making it optimal for CAN-centric embedded control without USB dependency.

FAQ
What is the maximum operating frequency of the LPC2292FBD144,551?
The LPC2292FBD144,551 achieves a maximum CPU clock frequency of 60 MHz using its on-chip programmable PLL. The PLL has a settling time of 100 µs and accepts input crystals from 1 MHz to 25 MHz. This 60 MHz operation is enabled by the 128-bit wide memory interface and accelerator architecture, allowing full-speed 32-bit code execution without wait states when accessing on-chip flash.
Does the LPC2292FBD144,551 support In-System Programming (ISP)?
Yes, the LPC2292FBD144,551 supports In-System Programming via its on-chip bootloader. It allows flash programming through UART0 or USB (when used with external USB-to-UART bridge), enabling field firmware updates without removing the chip. Erase operations (sector or full chip) complete in 400 ms, and 256-byte programming takes 1 ms-critical for rapid development iteration and remote maintenance of deployed LPC2292FBD144,551-based systems.
How many analog inputs does the LPC2292FBD144,551 ADC support, and what is its resolution?
The LPC2292FBD144,551 integrates an 8-channel, 10-bit successive approximation ADC with a minimum conversion time of 2.44 µs per sample. All eight analog inputs (AIN0–AIN7) are accessible on dedicated pins-including P0[27]–P0[30], P2[30]/AIN4, P2[31]/AIN5, P3[29]/AIN6, and P3[28]/AIN7-and are 5 V tolerant when configured for digital I/O, simplifying mixed-signal board design.
What debug and trace capabilities are built into the LPC2292FBD144,551?
The LPC2292FBD144,551 includes EmbeddedICE-RT logic for real-time debugging and an Embedded Trace Macrocell (ETM) for high-speed instruction execution tracing. These interfaces work with standard JTAG tools (e.g., ULINK2, Segger J-Link) and NXP's RealMonitor software, enabling non-intrusive breakpoint setting, live register inspection, and cycle-accurate program flow analysis-essential for validating timing-critical behavior in LPC2292FBD144,551 automotive and medical applications.
Is the LPC2292FBD144,551 pin-compatible with other devices in the LPC2292/2294 family?
Yes, the LPC2292FBD144,551 shares identical pin configuration with all LQFP144-packaged variants in the LPC2292/2294 family, including LPC2292FBD144/01 and LPC2294HBD144. Pin functions, electrical characteristics, and mechanical footprint are fully compatible across these parts-allowing drop-in replacement for functional upgrades (e.g., adding CAN channels via LPC2294) or temperature grade changes without PCB revision.
