LPC178x/7x

32-bit ARM Cortex-M3 microcontroller

 Clock generation:

 Clock output function that can reflect the main oscillator clock, IRC clock, RTC

clock, CPU clock, USB clock, or the watchdog timer clock.

 On-chip crystal oscillator with an operating range of 1 MHz to 25 MHz.

 12 MHz Internal RC oscillator (IRC) trimmed to 1% accuracy that can optionally be

used as a system clock.

 An on-chip PLL allows CPU operation up to the maximum CPU rate without the

need for a high-frequency crystal. May be run from the main oscillator or the

internal RC oscillator.

 A second, dedicated PLL may be used for USB interface in order to allow added

flexibility for the Main PLL settings.

 Versatile pin function selection feature allows many possibilities for using on-chip

peripheral functions.

 Unique device serial number for identification purposes.

 Single 3.3 V power supply (2.4 V to 3.6 V). Temperature range of

40 C to 85 C.

 Available as LQFP208, TFBGA208, TFBGA180, and LQFP144 package.

3.

Applications

 Communications:

 Point-of-sale terminals, web servers, multi-protocol bridges

 Industrial/Medical:

 Automation controllers, application control, robotics control, HVAC, PLC, inverters,

circuit breakers, medical scanning, security monitoring, motor drive, video intercom

 Consumer/Appliance:

 Audio, MP3 decoders, alarm systems, displays, printers, scanners, small

appliances, fitness equipment

 Automotive:

 After-market, car alarms, GPS/fleet monitors
