There are multiple VSS pins, all of them must be connected. VREF Reference voltage for the A/D converter (5V). VREF is also the supply voltage to the analog portion of the A/D converter and the logic used to read Port 0. Must be connected for A/D and Port 0 to function. ANGND Reference ground for the A/D converter. Must be held at nominally the same potential as VSS. Connect VSS and ANGND at chip to avoid noise problems. VPP Programming voltage. Also timing pin for the return from power down circuit. XTAL1 Input of the oscillator inverter and of the internal clock generator. XTAL2 Output of the oscillator inverter. CLKOUT Output of the internal clock generator. The frequency of CLKOUT is (/2 the oscillator frequency. It has a 50% duty cycle. RESET Reset input to and open-drain output from the chip. Input low for at least 4 state times to reset the chip. The subsequent low-to-high transition re-synchronizes CLKOUT and commences a 10-state-time RESET sequence. BUSWIDTH Input for buswidth selection. If CCR bit 1 is a one, this pin selects the bus width for the bus cycle in progress. If BUSWIDTH is a 1, a 16-bit bus cycle occurs. If BUSWIDTH is a 0 an 8-bit cycle occurs. If CCR bit 1 is a 0, the bus is always an 8-bit bus. NMI A positive transition causes a vector through 203EH. INST Output high during an external memory read indicates the read is an instruction fetch and output low indicates a data fetch. INST is valid throughout the bus cycle. INST is activated only during external memory accesses. EA Input for memory select (External Access). EA equal to a TTL-high causes memory accesses to locations 2000H through 3FFFH to be directed to on-chip ROM/OTPR OM. EA equal to a TTL-low causes accesses to these locations to be directed to off-chip memory. ALE/ADV Address Latch Enable or Address Valid output, as selected by CCR. Both pin options provide a latch to demultiplex the address from the address/data bus. When the pin is ADV, it goes inactive high at the end of the bus cycle. ALE/ADV is activated only during external memory accesses. RD Read signal output to external memory. RD is activated only during external memory reads. WR/WRL Write and Write Low output to external memory, as selected by the CCR. WR will go low for every external write, while WRL will go low only for external writes where an even byte is being written. WR/WRL is activated only during external memory writes. BHE/WRH Bus High Enable or Write High output to external memory, as selected by the CCR. BHE will go low for external writes to the high byte of the data bus. WRH will go low for external writes where an odd byte is being addressed. BHE/WRH is activated only during external memory writes. READY Ready input to lengthen external memory cycles. If the pin is low prior to the falling edge of CLKOUT, the memory controller goes into a wait mode until the next positive transition in CLKOUT occurs with READY high. When the external memory is not being used, READY has no effect. Internal control of the number of wait states inserted into a bus cycle (held not ready) is available in the CCR. HSI Inputs to High Speed Input Unit. Four HSI pins are available: HSI.0, HSI.1, HSI.2 and HSI.3. Two of them (HSI.2 and HSI.3) are shared with the HSO Unit. HSO Outputs from High Speed Output Unit. Six HSO pins are available: HSO.0, HSO.1, HSO.2, HSO.3, HSO.4 and HSO.5. Two of them (HSO.4 and HSO.5) are shared with the HSI Unit. 6 8XC196KB/8XC196KB16 PIN DESCRIPTIONS (Continued) Symbol Name and Function Port 0 8-bit high impedance input-only port. Three pins can be used as digital inputs and/or as analog inputs to the on-chip A/D converter. Port 1 8-bit quasi-bidirectional I/O port. These pins are shared with HOLD, HLDA and BREQ. Port 2 8-bit multi-functional port. All of its pins are shared with other functions in the 87C196KB. Pins P2.6 and P2.7 are quasi-bidirectional. Ports 3 and 4 8-bit bidirectional I/O ports with open drain outputs. These pins are shared with the multiplexed address/data bus, which has strong internal pullups. HOLD Bus Hold input requesting control of the bus. Enabled by setting WSR.7. HLDA Bus Hold acknowledge output indicating release of the bus. Enabled by setting WSR.7. BREQ Bus Request output activated when the bus controller has a pending external memory cycle. Enabled by setting WSR.7. TxD The TxD pin is used for serial port transmission in Modes 1, 2 and 3. In Mode 0 the pin is used as the serial clock output. RxD Serial Port Receive pin used for serial port reception. In Mode 0 the pin functions as input or output data. EXTINT A rising edge on the EXTINT pin will generate an external interrupt. T2CLK The T2CLK pin is the Timer2 clock input or the serial port baud rate generator input. T2RST A rising edge on the T2RST pin will reset Timer2. PWM The pulse width modulator output. T2UP-DN The T2UPDN pin controls the direction of Timer2 as an up or down counter. T2CAPTURE A rising edge on P2.7 will capture the value of Timer2 in the T2CAPTURE register. PMODE Programming Mode Select. Determines the EPROM programming algorithm that is performed. PMODE is sampled after a chip reset and should be static while the part is operating. SID Slave ID Number. Used to assign each slave a pin of Port 3 or 4 to use for passing programming verification acknowledgement. PALE Programming ALE Input. Accepted by the 87C196KB when it is in Slave Programming Mode. Used to indicate that Ports 3 and 4 contain a command/address. PROG Programming. Falling edge indicates valid data on PBUS and the beginning of programming. Rising edge indicates end of programming. PACT Programming Active. Used in the Auto Programming Mode to indicate when programming activity is complete. PVAL Program Valid. This signal indicates the success or failure of programming in the Auto Programming Mode. A zero indicates successful programming. PVER Program Verification. Used in Slave Programming and Auto CLB Programming Modes. Signal is low after rising edge of PROG if the programming was not successful. AINC Auto Increment. Active low signal indicates that the auto increment mode is enabled. Auto Increment will allow reading or writing of sequential EPROM locations without address transactions across the PBUS for each read or write. Ports 3 and 4 (Programming Mode) Address/Command/Data Bus. Used to pass commands, addresses, and data to and from slave mode 87C196KBs. Used by chips in Auto Programming Mode to pass command, addresses and data to slaves. Also used in the Auto Programming Mode as a regular system bus to access external memory. Should have pullups to VCC when used in slave programming mode. 7 8XC196KB/8XC196KB16 ELECTRICAL CHARACTERISTICS ABSOLUTE MAXIMUM RATINGS* NOTICE: This data sheet contains preliminary information on new products in production.

This is accomplished by setting IOC2.4 e 1. At higher frequencies (greater than 6 MHz) the clock prescaler should be enabled (IOC2.4 e 0) to allow the comparator to settle. state time e 2 XTAL1 The converter is ratiometric, so the absolute accuracy is directly dependent on the accuracy and stability of VREF. VREF must be close to VCC since it supplies both the resistor ladder and the digital section of the converter.

Missed Interrupt on P0.7, EXTINT The following differences exist between this data sheet (270909-005) and (270909-004). 1. ITL MAX was – 650 μA (270909-004). Now ITL MAX is – 800 μA (270909-005). 2. IIL2 was named IIL1 (270909-004). Now IIL2 is correctly named (270909-005). 2. HSI_ MODE Divide-by-Eight 3. IIL1 was omitted (270909-004). IIL1 MAX was added. IIL1 MAX is – 850 μA (270909-005). 4. TLLYV and TLLGV (270909-004) were removed. These timings are not required in high-speed system designs. REVISION HISTORY 5. An errata was added to the known errata section. There is a possibility to miss an external 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. 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 (270909-007) and (270909-006). 1. Package prefix variables have changed. These variables are now indicated by “x”. The following differences exist between 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. 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 – 15 ns (270909-003). Now THAHBVMIN is – 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. 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
