AT89S51-based design with a fixed intelligent and resilient. MCS-51family Minimum System Ver 3.3 PCB design changes and use someSMD components thus making it more reliable and better quality.Component layout was slightly changed but still compact with the same PCB size as the previous version.
PCB design is updated so that more reliable in suppressing noisefrom the power supply line and the noise caused by the influence of a magnetic field.
Based microcontroller AT89S51.
Serial port RS-232 interface standard for communication between computer and board Minimum System Ver 3.3.
Using a serial cable straight type. (version 3.0 using a serial cabletype cross)
8 Kbyte non-volatile memory (EEPROM) for storing programs anddata.
4 port input / output (I / O) with a capacity of 8 bits each port.
Port LCD with built-in routine (for character LCD with HD44780 driver/ compatible).
Works in two modes: download & stand-alone.
Expansion connector for connecting the Minimum System Ver 3.3with an add-on board that is compatible
Can accommodate the use of USB to Serial converter (which iscompatible UART serial modem).
Equipped with Loader Software for MS-DOS operating system andWindows.
Software Debugger DT51D equipped, with features: Free Run, StepOver, Trace Into, Memory Monitor, Watches & On-Line Help.
Dimensions: 10.3 cm x 8.4 cm x 1.9 cm
