LPC1822JBD144E Overview

The LPC185x/3x/2x/1x are Arm Cortex-M3 based microcontrollers for embeddedapplications. The Arm Cortex-M3 is a next generation core that offers systemenhancements such as low power consumption, enhanced debug features, and a highlevel of support block integration.

The LPC185x/3x/2x/1x operate at CPU frequencies of up to 180 MHz. The ArmCortex-M3 CPU incorporates a 3-stage pipeline and uses a Harvard architecture withseparate local instruction and data buses as well as a third bus for peripherals. The ArmCortex-M3 CPU also includes an internal prefetch unit that supports speculativebranching.

The LPC185x/3x/2x/1x include up to 1 MB of flash and 136 kB of on-chip SRAM, 16 kB ofEEPROM memory, a quad SPI Flash Interface (SPIFI), a State Configurable Timer (SCT)subsystem, two High-speed USB controllers, Ethernet, LCD, an external memorycontroller, and multiple digital and analog peripherals.
