Objective data sheet Rev. 2 — 27 May 2011 3 of 117 NXP Semiconductors LPC178x/7x 32-bit ARM Cortex-M3 microcontroller CAN controller with two channels. Digital peripherals: SD/MMC memory card interface. Up to 165 General Purpose I/O (GPIO) pins depending on the packaging, with configurable pull-up/down resistors, open-drain mode, and repeater mode. All GPIOs are located on an AHB bus for fast access and support Cortex-M3 bit-banding. GPIOs can be accessed by the General Purpose DMA Controller. Any pin of ports 0 and 2 can be used to generate an interrupt. Two external interrupt inputs configurable as edge/level sensitive. All pins on port 0 and port 2 can be used as edge sensitive interrupt sources. Four general purpose timers/counters, with a total of eight capture inputs and ten compare outputs. Each timer block has an external count input. Specific timer events can be selected to generate DMA requests. Quadrature encoder interface that can monitor one external quadrature encoder. Two standard PWM/timer blocks with external count input option. One motor control PWM with support for three-phase motor control. Real-Time Clock (RTC) with a separate power domain. The RTC is clocked by a dedicated RTC oscillator. The RTC block includes 20 bytes of battery-powered backup registers, allowing system status to be stored when the rest of the chip is powered off. Battery power can be supplied from a standard 3 V lithium button cell. The RTC will continue working when the battery voltage drops to as low as 2.1 V. An RTC interrupt can wake up the CPU from any reduced power mode. Event Recorder that can capture the clock value when an event occurs on any of three inputs. The event identification and the time it occurred are stored in registers. The Event Recorder is located in the RTC power domain and can therefore operate as long as there is RTC power. Windowed Watchdog Timer (WWDT). Windowed operation, dedicated internal oscillator, watchdog warning interrupt, and safety features. CRC Engine block can calculate a CRC on supplied data using one of three standard polynomials. The CRC engine can be used in conjunction with the DMA controller to generate a CRC without CPU involvement in the data transfer. Analog peripherals: 12-bit Analog-to-Digital Converter (ADC) with input multiplexing among eight pins, conversion rates up to 400 kHz, and multiple result registers. The 12-bit ADC can be used with the GPDMA controller. 10-bit Digital-to-Analog Converter (DAC) with dedicated conversion timer and DMA support. Power control: Four reduced power modes: Sleep, Deep-sleep, Power-down, and Deep power-down. The Wake-up Interrupt Controller (WIC) allows the CPU to automatically wake up from any priority interrupt that can occur while the clocks are stopped in Deep-sleep, Power-down, and Deep power-down modes. Processor wake-up from Power-down mode via any interrupt able to operate during Power-down mode (includes external interrupts, RTC interrupt, PORT0/2 pin interrupt, and NMI). Brownout detect with separate threshold for interrupt and forced reset. On-chip Power-On Reset (POR). |
