Notes to Table 4–15 through 4–19:
(1) See the Operating Requirements for Altera Devices Data Sheet.
(2) Maximum VCC rise time is 100 ms.
(3) The IOH parameter refers to high-level TTL or CMOS output current; the I OL parameter refers to low-level TTL or
CMOS output current.
(4) Capacitance is sample-tested only at TA = 25 °C and at a 20-MHz frequency.
As shown in Figure 4–19, the serial configuration device is an 8-pin or
Pin Information
16-pin device. The control pins on the serial configuration device are:
serial data output (DATA), active serial data input (ASDI), serial clock
(DCLK), and chip select (nCS). Table 4–20 shows the serial configuration
device's pin descriptions.
Figure 4–19 shows the Altera serial configuration device 8-pin SOIC
package and its pin-out diagram.
