Parameter | Symbol | Rating | Unit |
Supply voltage (I/O) | VDD | VSS − 0.5 to 4.5 | V |
Supply voltage (Internal Logic) | VDDL | VSS − 0.5∼VDDH | V |
Input voltage | VIN | S − 0.5 to VDDH + 0.5 | V |
Storage temperature | TSTG | −55 to 125 | |
Maximum dissipation (Ta = 70) | PD | 1 | W |
Note: Using an LSI at specifications higher than the maximum ratings can cause permanent damage to the LSI. For normal operation, use under the recommended operating conditions. Exceeding the recommended operating conditions may affect the reliability of the LSI.
The TMPR3912 contains 208 pins (LQFP) or 217 pins (FBGA) consisting of input, output, bi-directional, and power and ground pins. The TMPR3911 contains 176 pins (LQFP) or 177 pins (FBGA) consisting of input, output, bi-directional, and power and ground pins. The only difference between TMPR3911 and TMPR3912 is pin counts of power and ground pins. These pins are used to support various functions. The following sections describe the function of each pin including any special power-down considerations for each pin.
