LPC11C22FBD48/301,

The LPC11C22FBD48/301 is a 32-bit Microcontroller based on ARM Cortex-M0 core with RISC architecture operates at a maximum frequency of 50MHz. The device incorporates 16kB internal flash, 8kB internal RAM, four general purpose counters/timers, 8-channel 10-bit A/D converter with sample rates of up to 400ksps, high-speed CAN transceiver and 36 general-purpose I/O pins. This device also features peripherals like one UART, one inter-integrated circuit (I2C) and two serial peripheral interface (SPI) modules.

• ARM Cortex-M0 built-in nested vectored interrupt controller (NVIC)
• Serial wire debug
• System tick timer
• In-system programming (ISP)
• Flash ISP commands can be issued via UART or C_CAN
• GPIO pins can be used as edge and level sensitive interrupt sources
• High-current source output driver (20mA) on one pin
• High-current sink driver (20mA) on two I2C-bus pins in fast-mode plus
• Programmable watchdog timer (WDT)
• 10-bit ADC with input multiplexing among 8 pins
• 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
• 12MHz Internal RC oscillator trimmed to 1 % accuracy
• Crystal oscillator with an operating range of 1MHz to 25MHz
• Programmable watchdog oscillator with a frequency range of 7.8kHz to 1.8MHz
• PLL allows CPU operation up to the maximum CPU rate
• Clock output function with divider
• Integrated PMU (power management unit)
• Three reduced power modes - sleep, deep-sleep and deep power-down
• Processor wake-up from deep-sleep mode
• Power-on reset (POR)
• Brownout detect with four separate thresholds
• Unique device serial number for identification
