Overview

RTEMS BSP for Philips(NXP)'s ARM7 processor.

This BSP is designed for Philips's LPC2210/LPC2212/LPC2214/LPC2290/LPC2294 (LPC22xx) serial ARM processor. And it can be ported to LPC21xx ARM MCU.

Philip's LPC22xx ARM processor has an ARM7TDMI-S core, and can run at 60MHz. It has an external memory bus and peripherals like UART, I2C, SPI, ADC and etc. Some BSPs have got a flash chip (256k) and CAN.

The board has been developed from the LPC-E2214/LPC-E2294. It is also compatible with it. Base address is set to 0x81000000.

Features

  • MCU: LPC2214 16/32 bit ARM7TDMI-S™t with 256K Bytes Program Flash, 16K Bytes RAM, EXTERNAL MEMORY BUS, RTC,4x 10 bit ADC 2.44 uS, * 2x UARTs, I2C, SPI, 2x 32bit TIMERS, 7x CCR, 6x PWM, WDT, 5V tolerant I/O, up to 60MHz operation
  • standard JTAG connector with ARM 2x10 pin layout for programming/debugging with ARM-JTAG
  • optional ETM connector (not installed)
  • standard JTAG connector with ARM 2x10 pin layout for programming/debugging with ARM-JTAG
  • USB to RS232 convertor, board can take power only from USB port
  • RESET circuit with exterman control of Philips ISP utility via USB-RS232 virtual port
  • Jumpers for boot select from external memory
  • Jumpers for ISP/RUN mode
  • Ethernet controller with CS8900A and RJ45 connector
  • LCD 16x2 DISPLAY with BACKLIGHT
  • 2 BUTTONS
  • POTENTIOMETER connected to ADC
