FORTHstamp

FORTHstamp is a true single chip computer, based upon an Analog
Devices’ chip ADuC7020.  eForth is installed in flash memory and is used
to drive all the devices.  It is an excellent platform to use Forth to develop
real time applications.  

Small size 1-1/4" by 3/4"
42MIPS ARM7TDMI MCU Core
Single 3V power supply
Five 16-Channel, 1 MSPS, 12-Bit ADC
Four 12-Bit Rail-to-Rail Voltage Output DACs
42MIPS ARM7TDMI MCU Core
62K-Byte In-Circuit Re-Programmable Flash Program/Data Memory
8K-Byte SRAM
Serial Interface Ports (UART, SPI, and dual I2C)
13 Parallel general purpose IO port (GPIO)
In-System Serial Programming
FORTHstamp is discontinued because of the high manufacturing
costs.  It is too costly to do the surface mounting in the US.  ADI
(Analog Devices) is providing a kit with AUDC microcontroller
chip.  Please take a look at its offerings.

UART33 module is discontinued as well.

For documentation, download FORTHstamp.
UART33

Convert power from COM port to 3.3 V, which drives
a MAX3232 to communicate with ADuC7020 on
FORTHstamp.
