NXP 50-MHz, 32-bit Cortex-M0TM microcontrollers LPC1100 LPC1100 Cortex-M0 based microcontrollers with industry-leading power and efficiency Built around the new Cortex-M0 architecture, the smallest, lowest power, and most energy-efficient ARM core ever developed, these MCUs are ideally equipped for use in battery-powered consumer devices, smart meters, motor control, and more. Key features } ARM Cortex-M0 processor - 50-MHz operation - Nested Vectored Interrupt Controller for fast deterministic interrupts - Wakeup Interrupt Controller allows automatic wake from an priority interrupt - Three reduced-power modes: Sleep, Deep-sleep, and Deep power-down } Memories - Up to 128 KB Flash memory - Up to 16 KB SRAM } Serial Peripherals - UART with fractional baud rate generation, internal FIFO, and RS-485 RS-485 support - SPI controller 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 } Analog Peripherals : - 10-bit Analog-to-Digital Converter with eight channels and conversion rates up to 250K samples per second } Other peripherals : - Up to 42 General Purpose I/O (GPIO) pins with configurable pull-up/down resistors and a new, configurable open-drain operating mode - Four general purpose counter/timers, with a total of four capture inputs and 13 match outputs - Programmable Watchdog Timer (WDT) with lock-out feature - System tick timer - Each peripheral has its own clock divider for power savings Applications } Battery-powered systems } e-Metering } Consumer peripherals } Remote sensors } 16-bit applications The LPC1100 LPC1100 is the world's first Cortex-M0 based microcontroller series offering users a cost effective, very easy to use 32-bit MCU which is code and tool compatible with other NXP ARM-based MCU products. With 32-bit performance combined with multiple power modes and very low Deep sleep power, the LPC1100 LPC1100 offers industry leading energy efficiency greatly extending battery life. The LPC1100 LPC1100 sets new benchmarks in performance efficiency with dramatically improved code density enabling longer battery life and lower system costs.
