NXP | LPC1114FBD48/301,1

The LPC1111/12/13/14 are a ARM Cortex-M0 based, low-cost 32-bit MCU family, designed for 8/16-bit microcontroller applications, offering performance, low power, simple instruction set and memory addressing together with reduced code size compared to existing 8/16-bit architectures.

The LPC1111/12/13/14 operate at CPU frequencies of up to 50 MHz.

The peripheral complement of the LPC1111/12/13/14 includes up to 32 kB of flash memory, up to 8 kB of data memory, one Fast-mode Plus I2C-bus interface, one RS-485/EIA-485 UART, up to two SPI interfaces with SSP features, four general purpose counter/timers, a 10-bit ADC, and up to 42 general purpose I/O pins.

Features and benefits :

• System :
• ARM Cortex-M0 processor, running at frequencies of up to 50 MHz.
• ARM Cortex-M0 built-in Nested Vectored Interrupt Controller (NVIC).
• Serial Wire Debug.
• System tick timer.
• Memory :
• 32 kB (LPC1114), 24 kB (LPC1113), 16 kB (LPC1112), or 8 kB (LPC1111) on-chip flash programming memory.
• 8 kB, 4 kB, or 2 kB SRAM.
• In-System Programming (ISP) and In-Application Programming (IAP) via on-chip bootloader software.
• Digital peripherals :
• Up to 42 General Purpose I/O (GPIO) pins with configurable pull-up/pull-down resistors.
• GPIO pins can be used as edge and level sensitive interrupt sources.
• High-current output driver (20 mA) on one pin.
• High-current sink drivers (20 mA) on two I2C-bus pins in Fast-mode Plus.
• Four general purpose counter/timers with a total of four capture inputs and 13 match outputs.
• Programmable WatchDog Timer (WDT).
• Analog peripherals :
• 10-bit ADC with in
• Serial interfaces :
• UART with fractional baud rate generation, internal FIFO, and RS-485 support.
• Two SPI controllers with SSP features and with FIFO and multi-protocol capabilities (second SPI on LQFP48 and PLCC44 packages only).
• 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.
• Clock generation :
• 12 MHz internal RC oscillator trimmed to 1 % accuracy that can optionally be used as a system clock.
• Crystal oscillator with an operating range of 1 MHz to 25 MHz.
• 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 the system oscillator or the internal RC oscillator.
• Clock output function with divider that can reflect the system oscillator clock, IRC clock, CPU clock, and the Watchdog clock.
• Power control :
• Integrated PMU (Power Management Unit) to minimize power consumption during Sleep, Deep-sleep, and Deep power-down modes.
• Three reduced power modes: Sleep, Deep-sleep, and Deep power-down.
• Processor wake-up from Deep-sleep mode via a dedicated start logic using up to 13 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 48-pin LQFP package, 33-pin HVQFN package, and 44-pin PLCC package.
