3.2 Typical characteristics

Standard characteristics described below are just examples of the 7540 Group’s characteristics and are not

guaranteed. For rated values, refer to “3.1 Electrical characteristics”.

3.2.1 Mask ROM version

(1) Power source current characteristic example (VCC-ICC characteristics)

Fig. 3.2.1 VCC-ICC characteristics (in double-speed mode: Mask ROM version)

Measuring condition: When system is operating in double-speed mode (A/D conversion not executed),

Ta = 25 °C, Ceramic oscillation

Power source voltage Vcc [V]

f(XIN) = 6 MHz

f(XIN) = 4 MHz

f(XIN) = 2 MHz

f(XIN) = 1 MHz

Measuring condition: When system is operating in high-speed mode (A/D conversion not executed),

Ta = 25 °C, Ceramic oscillation

Power source voltage Vcc [V]

f(XIN) = 8 MHz

f(XIN) = 4 MHz

f(XIN) = 2 MHz

Fig. 3.2.3 VCC-ICC characteristics (in middle-speed mode: Mask ROM version)

Measuring condition: When system is operating in middle-speed mode (A/D conversion not executed),

Ta = 25 °C, Ceramic oscillation

Power source voltage Vcc [V]

f(XIN) = 8 MHz

f(XIN) = 4 MHz

f(XIN) = 2 MHz
