NOTES:
(a) The electrical specifications in this document for both the 8.39 and 16.78 MHz @ 3.3 V
±0.3 V are preliminary
and apply only to the appropriate MC68340V low voltage part.
(b) The 16.78-MHz specifications apply to the MC68340 @ 5.0 V
±5% operation.
(c) The 25.16 MHz @ 5.0 V
±5% electrical specifications are preliminary.
(d) For extended temperature parts TA = –40 to +85
°C. These specifications are preliminary.
1. Input-Only Pins:
BERR, BG, BKPT, BR, CTSB, CTSA, DREQ2, DREQ1, DSACK1, DSACK0, EXTAL, RxDB,
RxDA, SCLK, TCK, TDI,
TGATE2, TGATE1, TIN2, TIN1, TMS
Output-Only Pins: A23–A0,
AS, BG, CLKOUT, DACK2, DACK1, DS, FC3–FC0, FREEZE, IFETCH, IPIPE,
RMC
, RTSB, RTSA, R/W, R≈RDYA, SIZ1, SIZ0, TDO, TOUT2, TOUT1, TxDB, TxDA, T≈RDYA
Input/Output Pins:
Group 1: D15–D0
Group 2: A31–A24,
CS3–CS0, DONE2, DONE1, IRQ7, IRQ5, IRQ3, MODCK
Group 3:
HALT, RESET
2. V
OH
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 8.39 MHz @ 3.6 V.
6. Power dissipation measured with a system clock frequency of 8.39 MHz, all modules active.
7. Capacitance is periodically sampled rather than 100% tested.
