LPC84x
32-bit Arm Cortex-M0+ microcontroller
Free Running Oscillator (FRO). This oscillator provides a selectable 18 MHz, 24
MHz, and 30 MHz outputs that can be used as a system clock. Also, these outputs
can be divided down to 1.125 MHz, 1.5 MHz, 1.875 MHz, 9 MHz, 12 MHz, and 15
MHz for system clock. The FRO is trimmed to 1 % accuracy over the entire
voltage and temperature range of 0 C to 70 C.
Low power boot at 1.5 MHz using FAIM memory.
External clock input for clock frequencies of up to 25 MHz.
Crystal oscillator with an operating range of 1 MHz to 25 MHz.
Low power oscillator can be used as a clock source to the watchdog timer.
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 the system oscillator, the external clock
input, or the internal FRO.
Clock output function with divider that can reflect all internal clock sources.
Power control:
Reduced power modes: sleep mode, deep-sleep mode, power-down mode, and
deep power-down mode.
Wake-up from deep-sleep and power-down modes on activity on USART, SPI, and
I2C peripherals.
Timer-controlled self wake-up from deep power-down mode.
Power-On Reset (POR).
Brownout detect (BOD).
Unique device serial number for identification.
Single power supply (1.8 V to 3.6 V).
Operating temperature range -40 °C to +105 °C.
Available in LQFP64, LQFP48, HVQFN48, and HVQFN33 packages.
