Rev. 0, 6/2003 Addendum to MC68HC908LJ12 T echnical Data Addendum This addendum provides information to the following MCU devices:

  • MC68HLC908LJ12 (see page 1)  MC68HC08LJ12 (see page 9) The entire MC68HC908LJ12 Technical Data, Rev. 2 (Motorola document number MC68HC908LJ12/D) applies to the these two devices, with exceptions outlined in this addendum. Amendments to MC68HC908LJ12/D , Rev. 2, are documented on page 13. MC68HLC908LJ12 The MC68HLC908LJ12 is a low-voltage version of the MC68HC908LJ12, with an operating voltage range of 2.4 to 3.3V. FLASH Memory The FLASH memory can be read at operating voltages from 2.4 to 3.3V. Program or erase operations require a minimum operating voltage of 2.7V. Low-Voltage Inhibit (LVI) The LVI module is not designed for the MC68HLC908LJ12. After an MCU reset, the LVI module is disabled (LVIPWRD = 1 in CONFIG1). The LVIPWRD bit should be left as logic 1 (the default setting). Electrical Specifications following tables. Freescale Sem iconductor, I Freescale Semiconductor, Inc.
