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

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 devic-

es.

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 dia-

grams.

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 add-

ed to the known errata section.

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).

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 sys-

tem 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 – 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.

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”.
