ARM MCU, LPC Family LPC1100 Series Microcontrollers, ARM Cortex-M0, 32 bit, 50MHz, 48 KB, 48 PinsProduct OverviewThe LPC11U34FBD48/421 is a 32-bit Microcontroller based on ARM Cortex-M0 corewith RISC architecture operates at a maximum frequency of 50MHz. The deviceincorporates 40kB internal flash, 10kB internal RAM, 4kB EEPROM, two SSPinterfaces, four general purpose counters/timers, 8-channel 10-bit A/D converterwith sample rates of up to 400ksps, full speed USB 2.0 device and 40general-purpose I/O pins. This device also features peripherals like oneRS-485/EIA-485 USART with support for synchronous mode and smart card interface,one inter-integrated circuit (I2C) and two serial peripheral interface (SPI)modules. It is offering low power, simple instruction set and memory addressingtogether with reduced code size compared to existing 8/16-bit architectures.ARM Cortex-M0 built-in nested vectored interrupt controller (NVIC)Non-maskable interrupt (NMI) input selectable from several input sourcesSystem tick timerIn-system programming (ISP) and In-application programming (IAP)ROM-based USB drivers. flash updates via USB supportedROM-based 32-bit integer division routinesStandard JTAG (Joint test action group) test interface for BSDLSerial wire debugUp to 8 GPIO pins can be selected as edge and level sensitive interrupt sourcesHigh-current source output driver (20mA) on one pinHigh-current sink driver (20mA) on true open-drain pinsProgrammable windowed watchdog timer (WWDT)USB 2.0 Full-speed device controllerCrystal oscillator with an operating range of 1MHz to 25MHz12MHz High-frequency Internal RC oscillator (IRC)Internal low-power, low-frequency watchdog oscillator (WDO)PLL allows CPU operation up to the maximum CPU rateSecond, dedicated PLL is provided for USBIntegrated PMU (power management unit)Four reduced power modes - Sleep, deep-sleep, power-down and deep power-downApplicationsConsumer Electronics, Medical, Automation & Process Control, Industrial, Audio,Computers & Computer PeripheralsProduct InformationProduct Range: LPC Family LPC1100 Series MicrocontrollersNo. of Bits: 32bitData Bus Width: 32bitOperating Frequency Max: 50MHzCPU Speed: 50MHzProgram Memory Size: 48KBRAM Memory Size: 10KBIC Case / Package: LQFPNo. of Pins: 48PinsMCU Case Style: LQFPNo. of I/O's: 40I/O'sInterfaces: I2C, SSP, USART, USBEmbedded Interface Type: I2C, SSP, USART, USBSupply Voltage Min: 1.8VSupply Voltage Max: 3.6VMCU Family: LPCMCU Series: LPC1100Operating Temperature Min: -40°COperating Temperature Max: 85°C
