LPC1100: Scalable Entry Level 32-bit Microcontroller (MCU) based on Arm Cortex-M0 Cores
Overview
Features
Features
System
- Arm Cortex-M0 processor, running at frequencies of up to 50 MHz
- Arm Cortex-M0 built-in nested vectored interrupt controller (NVIC)
- Non-maskable interrupt (NMI) input selectable from several input sources
- Serial wire debug
- System tick timer
Memory
- Up to 64 KB on-chip flash programming memory
- Up to 8 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. In addition, a configurable open-drain mode is supported on the LPC1100L and LPC1100XL series
- 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 (not on LPC1112FDH20/102)
- Four general purpose counter/timers with up to eight capture inputs and up to 13 match outputs
- Programmable windowed WDT
Analog peripherals
- 10/12-bit ADC with up to 2 Msamples/s and up to eight channels
Serial interfaces
- Up to 3 UARTs with fractional baud rate generation, internal FIFO, and RS-485 support
- Up to 2 SPI controllers with SSP features and 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 (not on LPC1112FDH20/102)
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 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 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
- Power profiles residing in boot ROM allowing to optimize performance and minimize power consumption for any given application through one simple function call
- 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 up to four separate thresholds for interrupt and forced reset
Additional features
- Unique device serial number for identification
- Single power supply (1.8 V to 3.6 V)
- Available in WLCSP16, SO20, TSSOP20, TSSOP28, HVQFN24, HVQFN33, TFBGA48 and LQFP48 packages
