Objective data sheet Rev. 1.1 — 21 February 2011 3 of 60 NXP Semiconductors LPC122x 32-bit ARM Cortex-M0 microcontroller Digital peripherals Micro DMA controller with 21 channels. CRC engine. Two UARTs with fractional baud rate generation and internal FIFO. One UART with RS-485 and modem support and one standard UART with IrDA. SSP/SPI controller with FIFO and multi-protocol capabilities. I2C-bus interface supporting full I2C-bus specification and Fast-mode Plus with a data rate of 1 Mbit/s with multiple address recognition and monitor mode. I2C-bus pins have programmable glitch filter. Up to 55 General Purpose I/O (GPIO) pins with programmable pull-up resistor, open-drain mode, programmable digital input glitch filter, and programmable input inverter. Programmable output drive on all GPIO pins. Four pins support high-current output drivers. All GPIO pins can be used as edge and level sensitive interrupt sources. Four general purpose counter/timers with four capture inputs and four match outputs (32-bit timers) or two capture inputs and two match outputs (16-bit timers). Windowed WatchDog Timer (WWDT). Analog peripherals One 8-channel, 10-bit ADC. Two highly flexible analog comparators. Comparator outputs can be programmed to trigger a timer match signal or can be used to emulate 555 timer behavior. Power Three reduced power modes: Sleep, Deep-sleep, and Deep power-down. Processor wake-up from Deep-sleep mode via start logic using 12 port pins. Processor wake-up from Deep-power down and Deep-sleep modes via the RTC. Brownout detect with three separate thresholds each for interrupt and forced reset. Power-On Reset (POR). Integrated PMU (Power Management Unit). Unique device serial number for identification. 3.3 V power supply. Available as 64-pin and 48-pin LQFP package. 3. Applications eMetering Lighting Industrial networking Alarm systems White goods |
