NXP LPC2148 Solderless Proto-Board, 2x RS232, USB, SD/MMC, PS/2 US$25.00

NXP LPC2148 Solderless Proto-Board, 2x RS232, USB, SD/MMC, PS/2

This NXP LPC2148 development board features a 170-hole solderless prototyping breadboard and several built-in peripherals such as a buzzer, LEDs, potentiometer, PS/2, USB, two serial ports, SD/MMC slot, and more. No external programmer is required; the LPC2148 can be programmed from your PC via one of the DB9 serial ports. A standard 20-pin ARM JTAG interface also is provided for programming and debugging. The board has a connector for attaching an ESD-02 Bluetooth module (not included).

The LPC2148 is based on a 32-bit ARM7TDMI-S CPU core with real-time emulation and embedded trace support, combining a microcontroller with 512 kB embedded high-speed Flash memory. A 128-bit wide memory interface and a unique accelerator architecture enables 32-bit code execution at the maximum clock rate. For critical code size applications, the alternative 16-bit Thumb mode reduces code by more than 30 percent with minimal performance penalty.

Due to their tiny size and low power consumption, LPC2148 are ideal for applications where miniaturization is a key requirement, such as access control and point-of-sale. Serial communications interfaces ranging from a USB 2.0 Full-speed device, multiple UARTs, SPI, SSP to I2C-bus and 40 kB on-chip SRAM make these devices well suited for communication gateways and protocol converters, soft modems, voice recognition and low-end imaging, providing both large buffer size and high processing power. Various 32-bit timers, dual 10-bit ADC(s), 10-bit DAC, PWM channels and 45 fast GPIO lines with up to nine edge- or level-sensitive external interrupt pins make these microcontrollers suitable for industrial control and medical systems.
