this data sheet (270909-005) and (270909-004) 1 ITL MAX was b 650 mA (270909-004) Now ITL MAX is b 800 mA (270909-005) 2 IIL2 was named IIL1 (270909-004) Now IIL2 is correctly named (270909-005) 3 IIL1 was omitted (270909-004) IIL1 MAX was added IIL1 MAX is b 850 mA (270909-005) 4 TLLYV and TLLGV (270909-004) were removed These timings are not required in high-speed system designs 5 An errata was added to the known errata section There is a possibility to miss an external interrupt on P0 7 EXTINT The following differences exist between this data sheet (270909-004) and (270909-003) 1 The ROM (80C196KB) and ROMless (83C196KB) were combined with this data sheet resulting in no specification differences 2 The description of the prescalar bit for the A D has been enhanced 3 THAHBVMIN was b 15 ns (270909-003) Now THAHBVMIN is b 20 ns (270909-004) 4 TXHQZMAX was 1 TOSC (270909-003) Now TXHQZMAX is 2 TOSC (270909-004) This should have no impact on designs using synchronous serial mode 0 5 The change indicators for the 80C196KB are ‘‘E’’ ‘‘F’’ and ‘‘G’’ Previously there was only one change indicator ‘‘E’’ The change indicator is used for tracking purposes The change indicator is the last character in the FPO number The FPO number is the second line on the top side of the device FUNCTIONAL DEVIATIONS Devices marked with an ‘‘E’’ ‘‘F’’ or ‘‘G’’ have the following errata 1 Missed Interrupt on P0 7 EXTINT Interrupts occurring on P0 7 could be missed since the INT PEND EXTINT bit may not be set See techbit MC0893 2 HSI MODE Divide-by-Eight See Faxback 2192 REVISION HISTORY This data sheet (270909-006) is valid for devices with an ‘‘E’’ ‘‘F’’ or ‘‘G’’ at the end of the top side tracking number Data sheets are changed as new device information becomes available Verify with your local Intel sales office that you have the latest version before finalizing a design or ordering devices The following differences exist between this data sheet (270909-006) and (270909-005) 1 Removed ‘‘Word Addressable Only’’ from Port 3 and 4 in Table 2 2 Removed ICC1 active mode current at 3 5 MHz This specification is not longer required 3 Removed TLLYV and TLLGV from waveform diagrams 4 The HSI errata and CMPL with R0 were removed as this is now considered normal operation 5 The HSI MODE divide-by-eight errata was added to the known errata section 21 8XC196KB 8XC196KB16 The following differences exist between (-003) and version (-002) 1 The 12 MHz and 16 MHz devices were combined in this data sheet The 87C196KB 12 MHz only data sheet (272035-001) is now obsolete 2 Changes were made to the format of the data sheet and the SFR descriptions were removed 3 The -002 version of this data sheet was valid for devices marked with a ‘‘B’’ or a ‘‘D’’ at the end of the top side tracking number 4 The OSCILLATOR errata was removed 5 An errata was not documented in the -002 data sheet for devices marked with a ‘‘B’’ or a ‘‘D’’ This is the DIVIDE DURING HOLD READY errata When HOLD or READY is active and DIV DIVB is the last instruction in the queue the divide result may be incorrect 6 TXCH was changed from Min e 40 ns to Min e 20 ns 7 TRLCL was changed from Min e 5 ns to Min e 4 ns 9 IIL1 was changed from Max e b 6 mA to Max e b 7 mA 10 THAHBV was changed from Min e b 10 ns to Min e b 15 ns Differences between the -002 and -001 data sheets 1 The -001 version of this data sheet was valid for devices marked with a ‘‘C’’ at the end of the top side tracking number 2 Added 64L SDIP and 80L QFP packages 3 Added IIH1 4 Changed TCHWH Min from b 10 ns to b 5 ns 5 Changed TCHWH Max from a 10 ns to a 15 ns 6 Changed TWLWH Min from TOSC b 20 ns to TOSC b 15 ns 7 Changed TWHQX Min from TOSC b 10 ns to TOSC b 15 ns 8 Changed TWHLH Min from TOSC b 10 ns to TOSC b 15 ns 9 Changed TWHLH Max from TOSC a 15 ns to TOSC a 10 ns 10 Changed TWHBX Min from TOSC b 10 ns to TOSC b 15 ns 11 Changed THVCH Min from 85 ns to 55 ns 12 Remove THVCH Max 13 Changed TCLHAL Min from b 10 ns to b 15 ns 14 Changed TCLHAL Max from 20 ns to 15 ns 15 Changed TCLBRL Min from b 10 ns to b 15 ns 16 Changed TCLBRL Max from 20 ns to 15 ns 17 Changed THAHAX Min from b 10 ns to b 15 ns 18 Added HSI description to Functional Deviations 19 Added Oscillator description to Functional Deviations 22
