Product Code : SCL-EELE-13131

Indian Lab Suppliers supplies the 8051 Microcontroller Trainer Kit (Product ID: 13131) as part of its electronics engineering lab equipment range. It is a single-board 8-bit 8051 microcontroller trainer with hex keypad, six-digit display, 48 I/O lines and two RS-232C ports.

Quick Answer

The 8051/89C51 CPU runs at 10 or 12 MHz with 16 KB of monitor EPROM and 8 KB of user RAM (6264) backed by a NiCd battery; a spare socket takes RAM up to 64 KB. Two 8255s give 48 I/O lines on 26-pin FRC connectors, an 8253 adds three timer/counters, and an 8279 drives the 25-key hex keypad and six-digit seven-segment display. One RS-232C port uses an 8251 and a second uses the 8051’s own RX/TX, both on 9-pin D connectors. Programs are entered in keyboard mode or from a PC in serial mode, with examine/edit, single-step and breakpoint commands. Power comes from a built-in +5 V 1.5 A and ±12 V 250 mA supply.
