MX10L8050X  
In additional, Port 1 serves the functions of the following  
special features of the MX10L8050X :  
PROCESS INFORMATION  
This device is manufactured on a MXIC CMOS process.  
Port Pin  
P1.0  
Alternate Function  
T2 (External Count Input to Timer/  
Counter 2), Clock-Out  
PACKAGES  
MX10L8050  
0
P
C
P1.1  
T2EX (Timer/Counter 2 Capture/Reload  
Trigger and Direction Control)  
Temperature  
C=0°C to 070°C  
I=-40°C+085°C  
Port 2 : Port 2 is an 8-bit bidirectional I/O port with inter-  
nal pullups. The port 2 output buffers can drive LS TTL  
inputs. Port 2 pins that have 1's written to them are  
pulled high by the internal pullups, and in that state can  
be used as inputs. As inputs, Port 2 pins that are exter-  
nally pulled low will source current (IIL, on the data sheet)  
because of the internal pullups.  
Package  
P=PDIP  
Q=PLCC  
F=PQFP  
Port 2 emits the high-order address byte during fetches  
from external Program Memory and during accesses to  
external Data Memory that use 16-bit addresses (MOVX  
@DPTR). In this application it uses strong internal  
pullups when emitting 1's. During accesses to external  
Data Memory that use 8-bit addresses (MOVX @Ri),  
Port 2 emits the contents of the P2 Special Function  
Register.  
ROM Size  
0=64K Bytes  
PIN DESCRIPTIONS  
VCC : Supply voltage.  
VSS : Circuit ground.  
Port 3 : Port 3 is an 8-bit bidirectional I/O port with inter-  
nal pullups. The port 3 output buffers can drive LS TTL  
inputs. Port 3 pins that have 1's written to them are  
pulled high by the internal pullups, and in that state can  
be used as inputs. As inputs, Port 3 pins that are exter-  
nally pulled low will source current (IIL, on the data sheet)  
because of the internal pullups.  
Port 0 : Port 0 is an 8-bit, open drain, bidirectional I/O  
port. As an output port each pin can sink several LS  
TTL inputs. Port 0 pins that have 1's written to them  
float, and in that state can be used as high-impedance  
inputs.  
Port 0 is also the multiplexed low-order address and data  
bus during accesses to external Program and Data  
Memory. In this application it uses strong internal pullups  
when emitting 1's, and can source and sink serveral LS  
TTL inputs.  
Port 3 also serves the function of various special fea-  
tures of the 8051 Family, as listed below :  
Port Pin Alternate Function  
P3.0  
P3.1  
P3.2  
P3.3  
P3.4  
P3.5  
P3.6  
P3.7  
RXD (serial input port)  
TXD (serial output port)  
Port 1 : Port 1 is an 8-bit bidirectional I/O port with inter-  
nal pullups. The port 1 output buffers can drive LS TTL  
inputs. Port 1 pins that have 1's written to them are  
pulled high by the internal pullups, and in that state can  
be used as inputs. As inputs, Port 1 pins that are exter-  
nally pulled low will source current (IIL, on the data sheet)  
because of the internal pullups.  
INT0 (external interrupt 0)  
INT1 (external interrupt 1)  
T0 (Timer 0 external input)  
T1 (Timer 1 external input)  
WR (external data memory write sttobe)  
RD (external data memory read strobe)
