LPC2148 Module from SPJ

SM2148 / SM2138 Modules:

These modules offer a quick way to use LPC2148 or LPC2138 microcontroller for any application. These modules are “self contained” – that is, they include some minimum necessary components surrounding the microcontroller chip, for example Reset circuit, crystal for clock etc. Further, these modules comesin through-hole package, suitable for quick prototyping as well as production.

Module Specifications:

· Supported microcontrollers: LPC2148 and LPC2138 (both have ARM7TDMI-S architecture).

· On-chip 512KB flash that supports ISP and IAP + 40KB SRAM.

· Supply voltage required: 5VDC (minimum 4.75V, maximum 5.25V). The microcontroller chip itself operates on 3.3V, but the module includes a small voltage regulator that produces 3.3V from 5V.

· Power consumption during normal operation: 65 mA @ 5VDC (speed = 48 MHz).

· Module includes 12 MHz crystal. Operating speed can be boosted to 60 MHz using on-chip PLL; but 48 MHz is more suitable for USB applications.

· Module includes power-on reset circuit as well as push-button for manual reset.

· All port pins (up to 45 GPIO) and JTAG pins available on connector.

· All digital I/O pins are 5V tolerant.

· RS232 (3 wire) on separate connector, useful for In-System-Programming or any other purpose. Separate 2 pin jumper included for selecting ISP Program mode.

· Other interfaces: Two UARTs, Two I2C configurable as Master or Slave; SPI master or slave.

· Module includes I2C compatible 64KB EEPROM (AT24C512) for non-volatile data storage.

· In SM2148 only: On chip USB 2.0 Full Speed compliant Device Controller available on USB-B type receptacle.

· Low power real-time clock with independent power and dedicated 32.768 kHz clock input. Module connector has pins for connecting external battery (3VDC only) required for on chip RTC.

· Two on chip 10 Bit ADC provides 14 channels input.

· Single 10-bit D/A converter provides variable analog output.

· Miscellaneous features: Two 32-bit timers/external event counters (with four capture and four compare channels each), PWM unit (six outputs) and watchdog.

· Compact footprint, 35 mm X 45 mm.

· EAGLE libraries available, so module can be used as a component in your EAGLE schematic and PCB. Similar libraries will be soon made available for other CAD packages.

· Operating Temperature Range: 0°C to +70°C. Extended temperature range available for OE customers.
