1. VDD = 5.0 Vdc ±10%, VSS = 0 Vdc, TA = TL to TH
2. The RC oscillator (RCO) must be enabled (by setting the CSEL bit in the OPTION register) for EEPROM programming and
erasure when the E-clock frequency is below 1.0 MHz.

1. VDD = 5.0 Vdc ± 10%
2. During EPROM programming of the MC68HC711E9 device, the VPPE pin circuitry may latch-up and be damaged if the
input current is not limited to 10 mA. For more information please refer to MC68HC711E9 8-Bit Microcontroller Unit Mask
Set Errata 3 (Freescale document order number 68HC711E9MSE3.
3. Typically, a 1-kΩ series resistor is sufficient to limit the programming current for the MC68HC711E9. A 100-Ω series resis-
tor is sufficient to limit the programming current for the MC68HC711E20.
