LPC1102

32-bit ARM Cortex-M0 microcontroller

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.

Clock output function with divider that can reflect the external clock, IRC clock,

CPU clock, and the Watchdog clock.

Power control:

Integrated PMU (Power Management Unit) to minimize power consumption during

Sleep and Deep-sleep modes.

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.
