LPC2294JBD144,551

Microcontrollers Overview

The NXP LPC2294JBD144,551 is a 32-bit microcontroller based on the ARM7TDMI-S core, housed in a 144-pin LQFP package. It features 256 kB of embedded high-speed flash memory and 16 kB of static RAM. The device supports a maximum CPU clock of 60 MHz via an on-chip PLL. Key peripherals include four advanced CAN channels, two UARTs with hardware flow control, Fast I2C, two SPI interfaces, and an SSP controller. It also integrates an eight-channel 10-bit ADC, real-time clock, watchdog timer, and a configurable external memory interface.

Microcontrollers Feature Summary

• Fast GPIO ports enable port pin toggling up to 3.5 times faster than original devices.
• Dedicated result registers for ADC reduce interrupt overhead during data acquisition.
• UARTs include fractional baud rate generators and auto-bauding capabilities implemented in hardware.
• Buffered SSP serial controller supports SPI, 4-wire SSI, and Microwire formats.

Microcontrollers Applications

• Automotive control systems
• Industrial control applications
• Medical systems
• Fault-tolerant maintenance buses

Microcontrollers Procurement Notes

Verify the specific ordering suffix matches the required feature set. The /01 suffix indicates the inclusion of fast GPIO, SSP interface, enhanced UART, and ADC improvements compared to standard variants. Confirm the temperature range requirements align with the -40 °C to +125 °C specification for this package type before finalizing procurement orders.

Microcontrollers Selection Notes

Select this component when four independent CAN channels are required alongside high-speed GPIO performance. The /01 variant is necessary for designs utilizing the buffered SSP controller or enhanced UART features. Ensure the design accommodates the dual power supply requirement of 1.8 V for the CPU core and 3.3 V for I/O pads.

Microcontrollers Part Context

This part belongs to the LPC2292/2294 family of 16/32-bit ARM microcontrollers. The LPC2294 variant specifically distinguishes itself by providing four CAN channels, whereas the LPC2292 offers only two. Both share the same 256 kB flash and 16 kB RAM architecture within the 144-pin package options.
