The new LPC214x series is well suited for a variety of USB peripherals including car radios, POS terminals, printers, and joysticks. Not all ARM MCUs are implemented in the same way, and the implementation of the LPC214x family clearly sets it apart for customers. To be fully compliant with the USB 2.0 full-speed standard, the LPC214x series, based on the ARM7TDMI-S, incorporates 32 double-buffered endpoints with maximum packet size support and flexible DMA. This allows data from the USB device to transfer at higher speeds than previously capable, resulting in a decrease in downloading time for the consumer. In addition, the USB on the LPC214x provides Good Link LED output and Soft Connect programmable resistor functionality for increased manufacturing flexibility.

The LPC214x series is also unique because it has fast I/O capability with I/O speeds up to four times faster than competitive solutions. With its fast I/O feature, the software-driven I/O on the LPC214x can operate at 15 MHz.

Other on-board communication peripherals include two 16C550-compatible UARTs with hardware handshaking, two Fast I²C-bus (400 kbps) interfaces, two SPIs, and up to two 10-bit ADCs and a 10-bit DAC. Its multiple serial communications interface increase design flexibility, provide larger buffer size, and helps deliver higher processing power.

Pricing in quantities of 10,000 for the MCUs are as follows: the LPC2141 costs $3.60; the LPC2142 costs $4.20, LPC2144 $5.65, LPC2146 $6.75, and LPC2148 $7.50.
