NXP Semiconductors
LPC122x
32-bit ARM Cortex-M0 microcontroller
Crystal oscillator with an operating range of 1 MHz to 25 MHz.
12 MHz Internal RC (IRC) oscillator trimmed to 1 % accuracy that can optionally be
used as a system clock.
PLL allows CPU operation up to the maximum CPU rate without the need for a
high-frequency crystal. May be run from the system oscillator or the internal RC
oscillator.
Clock output function with divider that can reflect the system oscillator clock, IRC
clock, main clock, and Watchdog clock.
Real-Time Clock (RTC).
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); IEC-60335 Class B certified.
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.
