The 80C152 which is based on the MCS -51 CPU is a highly integrated single-chip 8-bit microcontroller
designed for cost-sensitive high-speed serial communications It is well suited for implementing Integrated
Services Digital Networks (ISDN) emerging Local Area Networks and user defined serial backplane applica-
tions In addition to the multi-protocol communication capability the 80C152 offers traditional microcontroller
features for peripheral I O interface and control
Silicon implementations are much more cost effective than multi-wire cables found in board level parallel-to-
serial and serial-to-parallel converters The 83C152 contains in silicon all the features needed for the serial-
to-parallel conversion Other 83C152 benefits include 1) better noise immunity through differential signaling or
fiber optic connections 2) data integrity utilizing the stawnwdw.aDradtaShdeeets4Uig.cnomed in CRC checks and 3) better modulari-
ty of hardware and software designs All of these cost network parameter and real estate improvements
apply to 83C152 serial links between boards or systems and 83C152 serial links on a single board

Pin Description
VCC Supply voltage
VSS Circuit ground
Port 0 Port 0 is an 8-bit open drain bidirectional I O port As an output port each pin
can sink 8 LS TTL inputs Port 0 pins that have 1s 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 memory if EBEN is pulled low During accesses to external Data
Memory Port 0 always emits the low-order address byte and serves as the multiplexed
data bus In these applications it uses strong internal pullups when emitting 1s
Port 0 also outputs the code bytes during program verification External pullups are
required during program verification
Port 1 Port 1 is an 8-bit bidirectional I O port with internal pullups Port 1 pins that
have 1s 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 externally being pulled low will source
current (IIL on the data sheet) because of the internal pullups
Port 1 also serves the functions of various special features of the 8XC152 as listed
below

Port 2 Port 2 is an 8-bit bidirectional I O port with internal pullups Port 2 pins that
have 1s 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 externally being pulled low will source
current (IIL on the data sheet) bewcwwa.uDastaeShoefett4hU.ecominternal pullups
Port 2 emits the high-order address byte during fetches from external Program
Memory if EBEN is pulled low During accesses to external Data Memory that use 16-
bit addresses (MOVX DPTR and DMA operations) Port 2 emits the high-order
address byte In these applications it uses strong internal pullups when emitting 1s
During accesses to external Data Memory that use 8-bit addresses (MOVX Ri)
Port 2 emits the contents of the P2 Special Function Register
Port 2 also receives the high-order address bits during program verification
Port 3 Port 3 is an 8-bit bidirectional I O port with internal pullups Port 3 pins that
have 1s 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 externally being pulled low will source
current (IIL on the data sheet) because of the pullups
Port 3 also serves the functions of various special features of the MCS-51 Family as
listed below
