Input buffer for the input pins ("I" and "IO") are set at the TTL level and the options are as follows.

(U: Having pull-up resistance, D: Having pull-down resistance, S: Schmitt trigger, R: Through rate control)

Numbers (4, 8) in the BUF column for the output pins ("O" and "IO") indicate Io (= 4 or 8 mA).

Specifications

(1) Package

Plastic QFP 144 pins (20 mm × 20 mm)

(2) Power consumption

5 V, 120 mA (600 mW)

(3) Maximum clock frequency

40 MHz
