Description

I/O

¾

Bidirectional 8-bit input/output port with pull-high resistors. Each bit can be de-

termined as NMOS output or Schmitt trigger input by software instructions.

I/O

Wake-up

or None

2-bit bidirectional input/output lines with pull-high resistors. Each bit can be de-

termined as NMOS output or Schmitt trigger input by software instructions.

Each bit can also be configured as wake-up input by code option.

I

Wake-up or 6-bit Schmitt trigger input lines with pull-high resistors. Each bit can be config-

None ured as a wake-up input by code option.

O

Level or Level or carrier output pin

Carrier PC0 can be set as CMOS output pin or carrier output pin by code option.

Crystal

or RC

OSC1, OSC2 are connected to an RC network or a crystal (determined by

code option) for the internal system clock. In the case of RC operation, OSC2

is the output terminal for 1/4 system clock (NMOS open drain output).

I

¾

Schmitt trigger reset input. Active low.

Absolute Maximum Ratings

Supply Voltage ...........................VSS-0.3V to VSS+4.0V

Input Voltage..............................VSS-0.3V to VDD+0.3V

Storage Temperature ............................-50°C to 125°C

Operating Temperature...........................-40°C to 85°C

Note: These are stress ratings only. Stresses exceeding the range specified under ²Absolute Maximum Ratings² may

cause substantial damage to the device. Functional operation of this device at other conditions beyond those

listed in the specification is not implied and prolonged exposure to extreme conditions may affect device reliabil-

ity.
