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.
