SOM Description
The phyCORE-390 is a System on Module in subminiature dimensions. It is populated with the Dallas 8-bit, 80C51-compatible DS80C390 microcontroller. All ports and decoded interface signals extend to standard 2.54 pitch pin header rows. The phyCORE-390 offers 22-bit continuous memory support, 128 KB (to 1 MB) of external Flash memory with PHYTEC FlashTools download utility for in system (ISP) Flash programming and 128 KB (to 1 MB) of external SRAM. Two CAN transceivers and a serial EEPROM device provide additional CAN support, with the latter enabling storage of configuration data. The module communicates via an RS-232 or RS-485 serial interface which is jumper selectable. Included is an optional I2C Real Time Clock and optional battery back-up of the SRAM and RTC. The board requires a single 5V power supply for operation and Flash programming.
