Product data sheet Rev. 2 — 21 November 2013 2 of 66 NXP Semiconductors LPC11E3x 32-bit ARM Cortex-M0 microcontroller Debug options: Standard JTAG (Joint Test Action Group) test interface for BSDL (Boundary Scan Description Language). Serial Wire Debug. Digital peripherals: Up to 54 General Purpose I/O (GPIO) pins with configurable pull-up/pull-down resistors, repeater mode, and open-drain mode. Up to 8 GPIO pins can be selected as edge and level sensitive interrupt sources. Two GPIO grouped interrupt modules enable an interrupt based on a programmable pattern of input states of a group of GPIO pins. High-current source output driver (20 mA) on one pin. High-current sink driver (20 mA) on true open-drain pins. Four general purpose counter/timers with a total of up to 8 capture inputs and 13 match outputs. Programmable Windowed WatchDog Timer (WWDT) with a dedicated, internal low-power WatchDog Oscillator (WDO). Analog peripherals: 10-bit ADC with input multiplexing among eight pins. Serial interfaces: USART with fractional baud rate generation, internal FIFO, a full modem control handshake interface, and support for RS-485/9-bit mode and synchronous mode. USART supports an asynchronous smart card interface (ISO 7816-3). Two SSP controllers with FIFO and multi-protocol capabilities. I2C-bus interface supporting the full I2C-bus specification and Fast-mode Plus with a data rate of up to 1 Mbit/s with multiple address recognition and monitor mode. I/O Handler for hardware emulation of serial interfaces and DMA; supported through software libraries.(LPC11E37HFBD64/401 only.) Clock generation: Crystal Oscillator with an operating range of 1 MHz to 25 MHz (system oscillator). 12 MHz high-frequency Internal RC oscillator (IRC) that can optionally be used as a system clock. Internal low-power, low-frequency WatchDog Oscillator (WDO) with programmable frequency output. PLL allows CPU operation up to the maximum CPU rate with the system oscillator or the IRC as clock sources. Clock output function with divider that can reflect the crystal oscillator, the main clock, the IRC, or the watchdog oscillator. Power control: Integrated PMU (Power Management Unit) to minimize power consumption during Sleep, Deep-sleep, Power-down, and Deep power-down modes. Power profiles residing in boot ROM provide optimized performance and minimized power consumption for any given application through one simple function call. Four reduced power modes: Sleep, Deep-sleep, Power-down, and Deep power-down. Processor wake-up from Deep-sleep and Power-down modes via reset, selectable GPIO pins, or the watchdog interrupt. Processor wake-up from Deep power-down mode using one special function pin. |
