General description
The LPC1102/1104 are an ARM Cortex-M0 based, low-cost 32-bit MCU, designed for 8/16-bit microcontroller applications, offering performance, low power, simple instruction set and memory addressing together with reduced code size compared to existing 8/16-bit architectures.

Features and benefits
■ System:
   ◆ ARM Cortex-M0 processor, running at frequencies of up to 50 MHz.
   ◆ ARM Cortex-M0 built-in Nested Vectored Interrupt Controller (NVIC).
   ◆ Serial Wire Debug.
   ◆ System tick timer.
■ Memory:
   ◆ 32 kB on-chip flash programming memory.
   ◆ 8 kB SRAM.
   ◆ In-Application Programming (IAP) and In-System Programming (ISP) support via on-chip bootloader software.
■ Digital peripherals:
   ◆ 11 General Purpose I/O (GPIO) pins with configurable pull-up/pull-down resistors and programmable open-drain mode.
   ◆ GPIO pins can be used as edge and level sensitive interrupt sources.
   ◆ Four general purpose counter/timers with a total of one capture input and 10 match outputs.
   ◆ Programmable windowed WatchDog Timer (WDT).
■ Analog peripherals:
   ◆ 10-bit ADC with input multiplexing among five pins.
■ Serial interfaces:
   ◆ UART with fractional baud rate generation, internal FIFO, and RS-485 support.
   ◆ One SPI controller with SSP features and with FIFO and multi-protocol capabilities (see Section 7.16).
■ Clock generation:
   ◆ 12 MHz internal RC oscillator trimmed to 1 % accuracy that can optionally be used as a system clock.
   ◆ Programmable watchdog oscillator with a frequency range of 9.4 kHz to 2.3 MHz.
   ◆ PLL allows CPU operation up to the maximum CPU rate without the need for a high-frequency crystal. May be run from an external clock or the internal RC oscillator.
   ◆ Clock output function with divider that can reflect the system oscillator clock, IRC clock, CPU clock, and the Watchdog clock (LPC1104 only).
■ Power control:
■ Integrated PMU (Power Management Unit) to minimize power consumption during Sleep and Deep-sleep modes.
   ◆ Power profiles residing in boot ROM allowing to optimize performance and minimize power consumption for any given application through one simple function call.
   ◆ Two reduced power modes: Sleep and Deep-sleep modes.
   ◆ Processor wake-up from Deep-sleep mode via a dedicated start logic using up to six of the functional pins.
   ◆ Power-On Reset (POR).
   ◆ Brownout detect with up to four separate thresholds for interrupt and forced reset.
■ Unique device serial number for identification.
■ Single 3.3 V power supply (1.8 V to 3.6 V).
■ Available as WLCSP16 package.
