±0.3 V specifications are preliminary and apply to the MC68349V.
(b) The 16.78-MHz @ 5.0 V
±5% specifications are preliminary and apply to the MC68349.
(c) The 25.16 MHz @ 5.0 V
±5% specifications are preliminary and apply to the MC68349.

Input-Only Pins: BERR, BG, BKPT, BR, CTSB, CTSA, DREQ2, DREQ1, DSACK1, DSACK0, EXTAL, RxDB,
RxDA, SCLK, TCK, TDI, TMS
Output-Only Pins: A23–A0, AS, BG, CLKOUT, DACK2, DACK1, DS, FC3–FC0, FREEZE, IFETCH, IPIPE0 ,
IPIPE1 , RMC , RTSB, RTSA, R/ W , R≈RDYA, SIZ1, SIZ0, TDO, TxDB, TxDA, T≈RDYA
Input/Output Pins:
Group 1: D31–D0
Group 2: A31–A24, CS3–CS0, DONE2, DONE1, IRQ7, IRQ5, IRQ3, MODCK
Group 3: HALT, RESET
2.
VOH specification for HALT, RESET, DONE2, and DONE1 is not applicable because they are open-drain pins.
3.
Supply current measured with system clock frequency of 16.78 MHz @ 5.25 V.
4.
Power dissipation measured with a system clock frequency of 16.78 MHz, all modules active.
5.
Supply current measured with system clock frequency of 16.78 MHz @ 3.6 V.
6.
Capacitance is periodically sampled rather than 100% tested.
