NXP announced the availability of its ARM Cortex-M0 based LPC1100 microcontroller family in December. NXP's LPC1100 is the lowest priced 32-bit MCU solution in the market, bringing higher value and ease of use than existing 8/16-bit microcontroller through unprecedented performance, simplicity, low power, and more importantly, dramatic reductions in code size for all 8/16-bit applications.

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 timers, a 10-bit ADC, and up to 42 general purpose I/O pins.

• ARM Cortex-M0 processor, running at frequencies of up to 50 MHz
• ARM Cortex-M0 built-in Nested Vectored Interrupt Controller (NVIC)
• 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
• 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
• Up to 42 General Purpose I/O (GPIO) pins with configurable pull-up/pull-down resistors
• Four general purpose timers/counters with a total of four capture inputs and 13 match outputs
• Programmable WatchDog Timer (WDT)
• System tick timer
• Serial Wire Debug
• High-current output driver (20 mA) on one pin
• High-current sink drivers (20 mA) on two I2C-bus pins in Fast-mode Plus
• 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
• Single 3.3 V power supply (1.8 V to 3.6 V)
• 10-bit ADC with input multiplexing among 8 pins
• GPIO pins can be used as edge and level sensitive interrupt sources
• Clock output function with divider that can reflect the system oscillator clock, IRC clock, CPU clock, and the Watchdog clock
• Processor wake-up from Deep-sleep mode via a dedicated start logic using up to 13 of the functional pins
• Brownout detect with four separate thresholds for interrupt and one threshold for forced reset
• Power-On Reset (POR)
• Crystal oscillator with an operating range of 1 MHz to 25 MHz
• 12 MHz internal RC oscillator trimmed to 1 % accuracy that can optionally be used as a system clock
• PLL allows CPU operation up to the maximum CPU rate without the need for a high-frequency crystal. May be run from the main oscillator, the internal RC oscillator, or the watchdog oscillator.
• Available as 48-pin LQFP package, 33-pin HVQFN package, and 44-pin PLCC package.
