General description

The LPC1102 is 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 operates at CPU frequencies of up to 50 MHz.
The peripheral complement of the LPC1102 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.

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 nine 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 7.8 kHz to 1.8 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.
■ 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 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.
