The NXP LPC2214FBD144,551 is a 16/32-bit ARM7-based microcontroller from the LPC2200 series, clocked at 60 MHz with 256 KB of on-chip Flash program memory and 16 KB of SRAM. It packs 112 general-purpose I/O lines into a 144-pin LQFP package (20×20 mm), making it a dense I/O controller for industrial and telecom equipment that needs to talk to multiple peripherals without external port expansion. The core runs from a 1.65 V to 1.95 V supply, and the part is rated for -40°C to 85°C operation — suitable for factory-floor control panels, outdoor base-station line cards, and engine-bay monitoring modules where the temperature swings are real.
60 MHz ARM7 core — what the speed rating means for bus timing
The ARM7 core runs at 60 MHz. The EBI/EMI and serial interfaces operate at that clock rate.
Connectivity and peripheral set — what hooks to the bus
The LPC2214 includes an EBI/EMI, I²C, SPI, SSI, SSP, Microwire, and UART/USART. The 8-channel 10-bit ADC and internal oscillator are on-chip.
