General description
The LPC1200 series extends NXP’s 32-bit ARM microcontroller
continuum by targeting a wide range of industrial applications
in the areas of factory and home automation. The series offers
a wide range of Flash memory sizes, from 32 to 128 KB, with
512 Bytes page erase. Benefitting from the ARM Cortex-M0
Thumb instruction set, the LPC1200 has up to 50% higher
code density compared to common 8/16-bit MCUs performing
typical tasks. The LPC1200 also features an optimized`
ROM-based divide library for Cortex-M0, which offers code
size saving and several times the arithmetic performance of
software based libraries. The high efficiency of the Cortex-M0
core also helps the LPC1200 achieve lower average power for
similar applications. The LPC1200 has up to 55 GPIO and new
onboard peripherals including DMA, CRC, comparators, an
RTC, and a 1% internal oscillator, which provides the accuracy
needed for Baud rate generation.
Additional features
`` Programmable high-current output driver on four pins
`` Processor wake-up from Deep-sleep mode via 12 port pins
or peripherals interrupts
`` Power-On Reset (POR)
`` Brownout detect with four separate thresholds for interrupt
and forced reset
`` 12 MHz internal RC oscillator trimmed to 1% accuracy that
can also be used as a system clock or Baud rate generator
`` PLL allows CPU operation up to the maximum CPU rate
without the need for a high-frequency crystal. Can be run
from the main oscillator, the internal RC oscillator, or the
Watchdog oscillator
`` Clock generation unit with divider that can reflect the main
oscillator clock, IRC clock, CPU clock, and Watchdog clock.
`` Available in 48- or 64-pin LQFP package
Up to 8 KB

DMA Controller
High-speed GPIO (55)
Development tools
The easy-to-use LPCXpresso IDE for the LPC1200 series
is priced under $30. Other development tools from IAR,
Keil, Hitex, and Code Red can be found at www.nxp.com/
microcontrollers. All NXP’s Cortex-M microcontrollers are
upwardly binary compatible and offer all the advantages of a
single development toolchain. Users can easily migrate their
designs between Cortex-M0 and Cortex-M3 with minimum effort.
