ARM7 BASED NXP-LPC 2148 DEVELOPMENT BOARD << Back   Our ARM7-based NXP-LPC2148 development board gives a quick start to embedded users to work in ARM domain.   Key features:   16-bit/32-bit ARM7TDMI-S microcontroller in a tiny LQFP64 package.   8 kB to 40 kB of on-chip static RAM and 32 kB to 512 kB of on-chip flash memory.   128-bit wide interface/accelerator enables high-speed 60 MHz operation.   EmbeddedICE RT and Embedded Trace interfaces offer real-time debugging with the on-chip RealMonitor software and high-speed tracing of instruction execution.   USB 2.0 Full-speed compliant device controller with 2 kB of endpoint RAM.   In addition, the LPC2146/48 provides 8 kB of on-chip RAM accessible to USB by DMA.   One or two (LPC2141/42 vs, LPC2144/46/48) 10-bit ADCs provide a total of 6/14 analog inputs, with conversion times as low as 2.44 ms per channel.   Single 10-bit DAC provides variable analog output (LPC2142/44/46/48 only).   Two 32-bit timers/external event counters (with four capture and four compare channels each), PWM unit (six outputs) and watchdog.   Low power Real-Time Clock (RTC) with independent power and 32 kHz clock input.   Multiple serial interfaces including two UARTs (16C550), two Fast I2C-bus (400 kbit/s), SPI and SSP with buffering and variable data length capabilities.   Vectored Interrupt Controller (VIC) with configurable priorities and vector addresses.   External interrupt pins available.   60 MHz maximum CPU clock available from programmable on-chip PLL.   Power saving modes include Idle and Power-down.   Individual enable/disable of peripheral functions as well as peripheral clock scaling for additional power optimization.   Processor wake-up from Power-down mode via external interrupt.   CPU operating voltage range of 3.0 V to 3.6 V (3.3 V ± 10 %) with 5 V tolerant I/O Pads.   Lcd Interface Port.   Buzzer Interface.   Test Leds.   << Back
