System Bus Read/Write Characteristics 1 (For the 8080 Series MPU)

*1 The input signal rise time and fall time (tr, tf) is specified at 15 ns or less. When the system cycle time is extremely fast, (tr +tf) V (tcYcs - tccLW - tccHw) for (tr + tf) £ (tcYcs - tccLR - tccHR) are specified. *2 All timing is specified using 20% and 80% of Vdd as the reference. *3 tccLW and tccLR are specified as the overlap between /CS1 being “L” (CS2 = “H”) and A/VR and /RD being at the 1L" level.

*1 The input signal rise time and fall time (tr, tf) is specified at 15 ns or less. When the system cycle time is extremely fast, (tr +tf) < {tcYcs - tEWLW - tEWHw) for {tr + tf) yi {tcYC6 - tEWLR - tEWHR) are specified. *2 All timing is specified using 20% and 80% of Vdd as the reference. *3 tEWLW and tEWLR are specified as the overlap between CS1 being “L” {CS2 = “H”) and E.

*1 The input signal rise and fall time (tr, tf) are specified at 15 ns or less *2 All timing is specified using 20% and 80% of Vdd as the standard.

Luminance is a cd/m (nits) measurement of the display’s white color (white screen). All measurements are performed in a dark ambient. Display luminance is defined as the average value of five (5) white screen measurements. The location of these 5 measurement points is shown in the drawing below. ^. . . Surface Luminance of all white screen (1+2+3+4+5) Screen Luminance Measurement Points (5) • Measurement point diameter: 3mm White luminance uniformity is a cd/m2 (nits) measurement of the display’s white color across the display screen. All measurements are performed in a dark ambient. Display...
