87C196CB - Automotive

2. ABSOLUTE MAXIMUM RATINGS have been added.

3. Maximum Frequency has been increased to 20 MHz.

4. Maximum ICC has been increased from 75 mA to 100 mA for the CB, 90 mA for the CA.

5. Idle Mode current has been increased to 35 mA from 30 mA for the CB, 40 mA for the CA.

6. Input leakage current for Port 0 (ILI1) was decreased to 1.5 µA from 2.0 µA for the CA.

7. The electrical characteristics for the CAN module were removed. The electrical characteristics

for TXCAN and RXCAN are identical to standard port pins.

8. TOSC (1/freq) was modified to reflect 20 Mhz timings.

9. TOFD (Oscillator Fail Detect Specification) for clock failure to RESET pin pulled low, was

added to the data sheet (4 µs min, 40 µs max)

10. TWHQX has been increased to TOSC –25 ns min from TOSC –30 ns min.

11. TRXDX has been replaced by TRHDX. TRLAZ has been increased to 20 ns max from 5 ns max.

12. I PP programming supply current has been increased to 200 mA from 100 mA.

13. TCONV Conversion time for 10 bit A/D conversions has been decreased to reflect 20 Mhz

operation.

14. RRST was added for the 87C196CA, min = 6 KΩ/max = 65 KΩ.

15. TCLLH–min/max parameters switched to accurately reflect this timing parameter.

16. TRLCL–Separate timings for the 87C196CA vs 87C196CB. TRLCL for the CB is min –8 ns,

max +20 ns. For the CA, TRLCL min +4 ns/max +30 ns.

17. TRLRH changed to TOSC –10 ns from TOSC –5 ns.

18. TAVGV added for the 87C196CB.

19. TLLGV added for the 87C196CB.

20. TCLGX added for the 87C196CB.

21. TRLDV–Separate timings for 87C196CB.TRLDV max = TOSC –30 ns. For the 87C196CA,

TRLDV max = TOSC – 22 ns.

22. HOLD/HOLDA timings added for the 87C196CB.

23. Slave Port Timings added for the 87C196CB.

24. Separate specifications for TPLPH for the 87C196CB, TPLPH, min = 100 TOSC. For the

87C196CA, TPLPH min = 50 TOSC.

25. Separate specifications for TPLDV for the 87C196CB, TPLDV min = 100 TOSC for the

87C196CA, TPLDV min = 50 TOSC.

26. 8-Bit mode A/D characteristics added.
