General description
The LPC1850/30/20/10 are ARM Cortex-M3 based microcontrollers for embedded applications. The ARM Cortex-M3 is a next generation core that offers system enhancements such as low power consumption, enhanced debug features, and a high level of support block integration.
FEATUREs and benefits
◾ Processor core
✦ ARM Cortex-M3 processor, running at frequencies of up to 180 MHz.
✦ ARM Cortex-M3 built-in Memory Protection Unit (MPU) supporting eight regions.
✦ ARM Cortex-M3 built-in Nested Vectored Interrupt Controller (NVIC).
✦ Non-maskable Interrupt (NMI) input.
✦ JTAG and Serial Wire Debug, serial trace, eight breakpoints, and four watch points.
✦ Enhanced Trace Module (ETM) and Enhanced Trace Buffer (ETB) support.
✦ System tick timer.
◾ On-chip memory
✦ 200 kB SRAM for code and data use.
✦ Multiple SRAM blocks with separate bus access.
✦ 64 kB ROM containing boot code and on-chip software drivers.
✦ 128 bit One-Time Programmable (OTP) memory for general-purpose use.
◾ Clock generation unit
✦ Crystal oscillator with an operating range of 1 MHz to 25 MHz.
✦ 12 MHz internal RC oscillator trimmed to 1 % accuracy over temperature and
voltage.
✦ Ultra-low power RTC crystal oscillator.
✦ Three PLLs allow CPU operation up to the maximum CPU rate without the need for
a high-frequency crystal. The second PLL is dedicated to the High-speed USB, the
third PLL can be used as audio PLL.
✦ Clock output.
◾ Configurable digital peripherals:
✦ State Configurable Timer (SCT) subsystem on AHB.
✦ Global Input Multiplexer Array (GIMA) allows to cross-connect multiple inputs and
outputs to event driven peripherals like timers, SCT, and ADC0/1.
