Pin description

Pin description

Figure 2 shows the LQPF64 package pinout, while Table 2, Table 3, Table 4, Table 5, and

Table 6 give the pin description.

The legend and abbreviations used in these tables are the following:

● Type

– I = input

– O = output

– S = supply

● Input level: A = Dedicated analog input

● In/Output level

– CT = CMOS 0.3VDD/0.7VDD with input trigger

– TT= TTL 0.8V / 2V with Schmitt trigger

● Output level

– D8 = 8mA drive

– D4 = 4mA drive

– D2 = 2mA drive
