• Manufacturer Part Number: TSC80251-SK
• Description: 8/16-bit Microcontroller with Serial Communication Interfaces
• Manufacturer: TEMIC [TEMIC Semiconductors]

Notes:
1. Under steady-state (non-transient) conditions, I
2. Capacitive loading on Ports 0 and 2 may cause spurious noise pulses above 0.4 V on the low-level outputs of ALE and Ports 1, 2, and
3. Capacitive loading on Ports 0 and 2 causes the V
4. Typical values are obtained using V
5. The input threshold voltage of SCL and SDA meets the I

test conditions.
3. The noise is due to external bus capacitance discharging into the Port 0 and Port 2 pins when these pins change from high to low. In
applications where capacitive loading exceeds 100 pF, the noise pulses on these signals may exceed 0.8 V. It may be desirable to qualify
ALE or other signals with a Schmitt Trigger or CMOS-level input logic.
