P500 Model Features: PHILIPS' 80C552 Microcontroller. 32 Bit IN/OUT with included: 8 Channel, 10 Bit A/D Port, 2 PWM output lines and an RS-232 Serial Port. On board 8K EPROM monitor 32K SRAM. Size: 3.3" x 2.7" (8.38cm x 6.86cm). Capable of writing/running to/from EEPROMs 100% code compatible with the 8051. 1 Spare /CE(Chip Enable) line.

Assembler, Small-C compiler, uploading and EEPROM programming software included, upon purchasing any of our boards. All software features can be managed from within a single software program.

With the software included, applications can be easily developed in 3 steps:

1) Edit a program in Assembly or Small-C
2) Assemble or compile the just edited program
3) Send the program's HEX file through the serial port on to the board's SRAM or EEPROM.

After the last byte is received, the board's monitor automatically gives control to the just received program.

EEPROM Programming Features:
* Upload and Save a program into EEPROM.
* Upload, Save and Run a program into EEPROM.
* Run a previously Saved program from EEPROM.

As described above, the board comes with a 32K SRAM for program upload. Instead of the 32K SRAM, the user has the option of using 8K or 32K EEPROMs or NVRAMs, either can be programmed by the board.

The on board 8K EPROM monitor IC can be replaced with a programmed EEPROM or NVRAM for standalone implementation. This gives the user the capability of using up to 64K of memory.

The spare /CE line has been specially added to allow easy expansion of the P500 I/O lines. Assuming an 8255 is to be used, it can be easily wired without any additional interface ICs between the P500 and the 8255.

The board is designed to easily allow installation of a 5V Regulator IC. (not included).
