ADuC702x Modules from SPJ (for ADuC7024, ADuC7025, ADuC7026, ADuC7027)

ADuC702x Modules:

These modules offer a quick way to use AduC702x microcontrollers 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 come in through-hole package, suitable for quick prototyping as well as production. These modules support 4 microcontrollers from the ADuC702x family, yet all 4 modules come in same size and shape and very similar connector pinout.

Modules Specifications:

· Supported microcontrollers: ADuC7024, ADuC7025, ADuC7026 and ADuC7027.

· All these microcontrollers are ARM7TDMI architecture.

· On-chip 62KB ISP flash, 8KB SRAM. This is enough for many applications like Instrumentation or PID loop controllers etc.

· 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: 35 mA @ 5VDC (speed = 5.22 MHz); 65 mA @ 5VDC (speed = 41.78 MHz).

· Module includes crystal for main clock. Default operating speed is 5.22MHz; can be boosted to 41.78MHz using on-chip PLL.

· Alternatively, external clock up to 44MHz can be supplied to module.

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

· All port pins (up to 40 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 push-button included for selecting ISP Program mode.

· Other interfaces: Two I2C configurable as Master or Slave; SPI master or slave, up to 3.48 MHz.

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

· Also includes I2C compatible RTC (DS1338). Battery for RTC maybe connected externally. Module connector has pins for connecting external battery (3VDC only).

· Analog Inputs: up to 16 ADC channels, 12 bit resolution, 1 Mega-samples per second. Default internal V_REF is 2.5V; external V_REF from 0.625 to 3.3V can be applied.

· On-chip temperature sensor (±3°C).

· On-chip voltage comparator.

· Analog outputs: up to 4 DAC channels, 12 bit resolution.

· Miscellaneous features: 4 timers, wakeup and watchdog timer, power supply monitor, 3 phase 16 bit PWM generator, Programmable Logic Array (PLA).

· 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: −20°C to +70°C.
