1.5 Operating Voltage
1) Voltage: VDD=4.5 to 6.0 V DC at operating
VDD=3.5 to 6.0 V DC at low speed mode.*1
*1 The LSI is operated at low speed mode for first 60 ms after resetting the system.
2) Current:
VDD=5.0 V
At operating : 2.5 mA (typ.)
At power-down : DC2 0.5 mA (typ.)
At power-down : DC3 0.5 uA (typ.)
1.6 Oscillation frequency
4.19 MHz ±0.5%

2.2 Operating Range

CBM-909PC Series User’sManual
low speed mode 3.5~6.0 *2 V
Operating temperature Top — –40~85 ˚C
Note)
*1. If the input voltage exceeds a rated value, malfunctioning results, and in the worst case, the IC may be destroyed.
At power-on time, do not apply an input signal prior to VDD.
*2 Under regular operations it will operate in the high speed mode between the range of 4.5-6.0 V
Before moving on to the normal operations after the power down or power on function, it will operate in low
speed between the 60 ms and operates between 3.5 and 6.0 V.
Ensure that an input signal is not input before the VDD when turning on the power. If the input signal should
come first, then add an electric current limited resistance (1k-ohm) in the series with the input ports.

set.
At power-down mode, the pull-up resistance in ports P20~P23, P30~P33, P60~P63 and P70~P73 will be set.
Ports P40~P43, and P50~P53 are not built in pull-up resistance.
