D8748H

The D8748H is designed as one kind of totally self-sufficient, 8-bit parallel computers fabricated on single silicon chips using intel's advanced N-channel silicon gate HMOS-E process.

D8748H has eight features. (1)High performance HMOS-E. (2)Interval timer/event counter. (3)Two single level interrupts. (4)Single 5V supply. (5)Over 96 instructions; 90% single byte. (6)Compatible with 8080/8085 peripherals. (7)Easily expandable memory and I/O. (8)Up to 1.35us instruction cycle; all instructions 1 or 2 cycles. Those are all the main features.

Some absolute maximum ratings of D8748H have been concluded into several points as follow. (1)its ambient temperature under bias would be from 0°C to 70°C. (2)Its storage temperature range would be from -65°C to 150°C. (3)Its voltage on any pin with respect to ground would be from -0.5V to 7V. (4)Its power dissipation would be 1W. It should be noted that stresses above those listed in absolute maximum ratings may cause permanent damage to device.

Also some electrical characteristics of D8748H are concluded as follow. (1)Its input low voltage (all except RESET, X1, X2) would be min -0.5V and max 0.8V. (2)Its input low voltage RESET, X1, X2 would be min -0.5V and max 0.6V. (3)Its input high voltage all except XTAL1, XTAL2, RESET would be min 2.0V and max Vcc. (4)Its input high voltage X1, X2, RESET would be min 3.8V and max Vcc. (5)Its output low voltage would be max 0.45V. (6)Its output high voltage would be min 2.4V. (7)Its leakage current T1, /INT would be max +/-10uA. (8)Its input leakage current P10-P17, P20-P27, EA, SS would be max -500uA. (9)Its input leakage current RESET would be min -10uA and max -300uA. (10)Its leakage current BUS, T0 (high impedance state) would be max +/-10uA. And so on. At present we have not got so much information about this IC and we would try hard to get more information about it.
