396 / 410 page  Page 382 25. Electrical Characteristics 25.3 DC Characteristics TMP89FS60 RA003 Note 1: Typical values shown are Topr = 25°C and V DD = 5.0 V, unless otherwise specified. Note 2: IDD does not include IREF. It is the electrical current in the state in which the peripheral circuitry has been operated. Note 3: VIN : The input voltage on the pin except MODE pin, VMODE : The input voltage on the MODE pin Note 4: When performing a write or erase on the flash memory or activating a security program in the flash memory, make sure that the operating temperature Topr is within the range −10°C to 40°C. If the temperature is outside this range, the result- ant performance cannot be guaranteed. Note 5: In SLOW1 mode, the difference between the peak current and the average current becomes large. Note 6: Each supply current in SLOW2 mode is equivalent to that in IDLE0, IDLE1 and IDLE2 modes. Note 7: When a program operates in the flash memory or when data is being read from the flash memory, the flash memory oper- ates intermittently, and a peak current flows, as shown in Figure 25-4. In this case, the supply current IDD (in NORMAL1, NORMAL2 and SLOW1 modes) is defined as the sum of the average peak current and MCU current. Note 8: If a write or erase is performed on the flash memory or a security program is enabled in the flash memory, an instanta- neous peak current flows, as shown in Figure 25-5. Note 9: The circuit of a power supply must be designed such as to enable the supply of a peak current. This peak current causes the supply voltage in the device to fluctuate. Connect a bypass capacitor of about 0.1 µF near the power supply of the device to stabilize its operation. (VSS = 0 V, Topr = −40 to 85°C) Parameter Symbol Pins Condition Min Typ.
