This device contains protective cir- cuitry against damage due to high static voltages or electrical fields; however, it is advised that normal precautions be taken to avoid ap- plication of any voltages higher than maximum-rated voltages to this high-impedance circuit. Reliability of operation is enhanced if unused inputs are tied to in appropriate logic voltage level (e.g., either GND or VCC).

The average chip-junction temperature, T j, in °C can be obtained from: Tj = T A + (PD ° 03A) (1 where:. .. T A = Ambient Temperature, °C 0jA = Package Thermal Resistance, Junction-to-Ambient, °C/W PD = PINT+ PI/O 'PINT = IccxVcc, Watts-- Chip lnternaI Power PI/O . - Power,Dissipationon Input and Output Pins -- User Determined -. For most applications PI/O<PINT and can be neglected. ' The foliowing is an approximate relationship between PD and Tj (if PI/O is neglected):. .. . Solving equations (1)and (2) forKgives: ' ' " " ": K = PD" (TA + 273°C) + eJA ° PD 2 (3) where K is a constant pertaining to the particular part. K can be determined from equation (3) by measuring PD (at equilibrium) for a known T A. Using this value of K, the values (~f PD and Tj can be obtained by solving'equ"ations (1) and (2) iteratively for any value of T A. The total thermal resistance of a package (0jA)can be separated into two components, 0jC and 0CA, representing the barrier to heatflow from the semiconductor junction to the package (case) surface (eJC) and from the case to the outside ambient (0CA). These terms are related by the equation: 0jA=0jC+0CA (4) ejC is device related and cannot be influenced by the user. However, 0CA is user dependent and can be minimized by such thermal management tech- niques as heat sinks, ambient air cooling, and thermal convection. Thus, good thermal management on the part of the user can significantly reduce eCA so that 0jA approximately equals 0jC. Substitution of ejC for 0jA in equation (1) will result in a lower semiconductor junction temperature. Values for thermal resistance presented in this document, unless.estimated, were derived using the procedure described in Motorola Reliability Report 7843, "Thermal Resistance Measurement Method for MC68XX Microcom- ponent Devices," and are provided for design purposes only. Thermal meas- urements are complex and dependent on procedure and setup. User derived values for thermal resistance may differ. MC68030~ELECTRICAL;SP.ECIFICATIO NS •MOTOROLA

- This number can be reduced to 5 ns if strobes have equal loads. 2. If the asynchronous setup time (#47A) requirements are satisfied, the DSACKx low to data setup time (#31) and DSACKx low to BERR low setup time (#48) can be ignored. The data must only satisfy the data-in clock low setup time (#27) for the following clock Cycle, and BERR must only satisfy the late BERR low to clock low setup time (#27A) for the following clock cycle. 3. This parameter specifies the maximum allowable skew between DSACK0 to DSACK1 asserted or DSACK1 to DSACK0 asserted specification #47A must be met by DSACK0 or DSACK1. 4. This specification applies to the first (DSACK0 or DSACK1) DSACKx signal asserted. In the absence of DSACKx, BERR is an asynchronous input using the asynchronous input setup time (#47A). 5. DBEN may stay asserted on consecutive write cycles• 6. The minimum values must be met to guarantee proper operation. If this maximum value is exceeded, B'-G may be reasserted. 7. This specification indicates the minimum high time for ECS and OCS in the event of an internal cache hit followed immediately by another cache hit, a cache miss, or an operand cycle. 8. This__specification guarantees ~)peration with the MC68881/MC68882, which specifies a minimum time for ~ negated
- to,AS asserted (specification #13A in the MC68881/MC68882 User's Manual). Without this specification, incorrect
- interpretation of specifications #9A and #15 would indicate that the MC68030 does not meet the MC68881/MC68882 requirements. 9. This specification allows a system designer to guarantee data hold times on the output side of data buffers that have output enable signals generated with DBEN. The timing on DBEN precludes its use for synchronous READ cycles with no wait states. 10. These specifi(;ations allow system designers to guarantee that an alternate bus master has stopped driving the bus when the MC68030 regains control of the bus after an arbitration sequence. .11. DS will not be asserted for synchronous write cycles with no wait states~ 12. These hold times are specified with respect to strobes (asynchronous) and with respect to the clock (synchronous). The designer is free to use either time. 13. Synch?or~ous__ inputs must meet specifications #60 and #61 with stabJe logic levels for all rising edges of the clock while AS is asserted. These values are specified relative to the high level of the rising clock edge The values originally published were specified relative to the low level of the rising clock edge. 14. This specification allows system des~qners'._.tto qualify the~ signal of an MC68881/MC68882 with AT (allowing 7 ns for a gate delay) and still meet the CS to DS setup time requirement (spec 8B) of the MC68881/MC68882.
