    Code Density for LPC11xx


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.

The LPC1102/1104 operate at CPU frequencies of up to 50 MHz.

The peripheral complement of the LPC1102/1104 includes 32 kB of flash memory, 8 kB of data memory, one RS-485/EIA-485 UART, one SPI interface with SSP features, four general purpose counter/timers, a 10-bit ADC, and 11 general purpose I/O pins.

Remark: The LPC1104 has a revised pinout and contains several features not found in the LPC1102:

  • Two extra GPIO pins (PIO0_1 and PIO0_6).
  • Extra match output (CT32B0_MAT2).
  • CLKOUT feature.
  • Easier re-entry to ISP via PIO0_1.
  • SSP0_CLK available on two pins (A1 and A2) to support debugging of SSP communication.
  • Better positioning of the XTALIN pin for easier PCB layout.

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.
  • 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 three 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.

Applications
