PROGRAM MEMORY Up to 8 Kbytes of the program memory can reside in the on-chip ROM Also the device
can address up to 64K of program memory external to the chip
DATA MEMORY This microcontroller has a 256 x 8 on-chip RAM In addition it can address up to 64 Kbytes of
external data memory
The Intel 8XC51GB is a single-chip control oriented microcontroller which is fabricated on Intel’s CHMOS III-E
technology The 8XC51GB is an enhanced version of the 8XC51FA and uses the same powerful instruction
set and architecture as existing MCS 51 microcontroller products Added features make it an even more
powerful microcontroller for applications that require On-Chip A D Pulse Width Modulation High Speed I O
up down counting capabilities and memory protection features It also has a more versatile serial channel that
facilitates multi-processor communications

External Interrupt INT2 – INT6
RST Reset input A low on this pin for two machine
cycles while the oscillator is running resets the de-
vice The port pins will be driven to their reset condi-
tion when a voltage below VIL max voltage is ap-
plied whether the oscillator is running or not An
internal pullup resistor permits a power-on reset with
only a capacitor connected to VSS
ALE PROG Address Latch Enable output pulse for
latching the low byte of the address during accesses
to external memory This pin (ALE PROG) is also
the program pulse input during programming of the
87C51GB
In normal operation ALE is emitted at a constant
rate of the oscillator frequency and may be used
for external timing or clocking purposes Note how-
ever that one ALE pulse is skipped during each ac-
cess to external Data Memory
If desired ALE operation can be disabled by setting
bit 0 of SFR location 8EH With this bit set the pin is
weakly pulled high However the ALE disable fea-
ture will be suspended during a MOVX or MOVC in-
struction idle mode power down mode and ICE
mode The ALE disable feature will be terminated by
reset When the ALE disable feature is suspended or
terminated the ALE pin will no longer be pulled up
weakly Setting the ALE-disable bit has no affect if
the microcontroller is in external execution mode
Throughout the remainder of this data sheet ALE
will refer to the signal coming out of the ALE PROG
pin and the pin will be referred to as the ALE PROG
pin
PSEN Program Store Enable is the read strobe to
external Program Memory
When the 8XC51GB is executing code from external
Program Memory PSEN is activated twice each ma-
chine cycle except that two PSEN activations are
skipped during each access to external Data Memo-
ry
EA VPP External Access enable EA must be
strapped to VSS in order to enable the device to
fetch code from external Program Memory locations
0000H to 1FFFH Note however that if either of the
Program Lock bits are programmed EA will be inter-
nally latched on reset
EA should be strapped to VCC for internal program
executions

ONCE MODE
The ONCE (‘‘On-Circuit Emulation’’) Mode facilitates
testing and debugging of systems using the
8XC51GB without removing it from the circuit The
ONCE Mode is invoked by
1) Pulling ALE low while the device is in reset and
PSEN is high
2) Holding ALE low as RESET is deactivated
While the device is in ONCE Mode the Port 0 pins
float and the other port pins and ALE and PSEN are
weakly pulled high The oscillator circuit remains ac-
tive While the 8XC51GB is in this mode an emula-
tor or test CPU can be used to drive the circuit Nor-
mal operation is restored when a normal reset is ap-
plied
Watchdog Timer (WDT)
The 8XC51GB contains a dedicated Watchdog Tim-
er (WDT) to allow recovery from a software or hard-
ware upset The WDT consists of a 14-bit counter
which is cleared on Reset and subsequently incre-
mented every machine cycle While the oscillator is
running the WDT will be incrementing and cannot
be disabled The counter may be reset by writing
1EH and E1H in sequence to the WDTRST Special
Function Register If the counter is not reset before
it reaches 3FFFH (16383D) the chip will be forced
into a reset sequence by the WDT This works out to
12 28 ms 16 MHz WDTRST is a write only regis-
ter The WDT does not force the external reset pin
low
While in Idle mode the WDT continues to count If
the user does not wish to exit Idle with a reset then
the processor must be periodically ‘‘woken up’’ to
service the WDT In Power Down mode the WDT
stops counting and holds its current value
Serial Expansion Port (SEP)
The Serial Expansion Port is a half-duplex synchro-
nous serial interface with the following features
Four Clock Frequencies
Four Interface Modes
Edges
Interrupt Driven
XTAL 12 24 48 96
High Low Falling Rising
Oscillator Fail Detect (OFD)
The Oscillator Fail Detect circuitry triggers a reset if
the oscillator frequency is lower than the OFD trig-
ger frequency It can be disabled by software by writ-
ing E1H followed by 1EH to the OFDCON register
Before going into Power Down Mode the OFD must
be disabled or it will force the GB out of Power
Down The OFD has the following features
OFD Trigger Frequency Below 20 KHz the
8XC51GB will be held in reset Above 400 KHz
the 8XC51GB will not be held is reset
Functions in Normal and Idle Modes
Reactivated by Reset (or External Interrupt Ze-
ro One Pins) after Software Disable
8XC51GB EXPRESS
The Intel EXPRESS products are designed to meet
the needs of those applications whose operating re-
quirements exceed commercial standards
With the commercial standard temperature range
operational characteristics are guaranteed over the
temperature range of 0 C to a70 C With the ex-
tended temperature range option operational char-
acteristics are guaranteed over the range of b40 C
to a85 C The 87C51GB EXPRESS is packaged in
the 68-lead PLCC package In order to designate a
part as an EXPRESS part a ‘‘T’’ is added as a prefix
to the part number TN87C51GB denotes an EX-
PRESS part in a PLCC package
All AC and DC parameters in this data sheet apply to
the EXPRESS devices
