AUTOMOTIVE 87C51FA/FB/FC/FC-20

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 inter-

nal pullups when emitting 1’s, and can source and

sink several LS TTL inputs.

Port 0 also receives the code bytes during EPROM

programming, and outputs the code bytes during

program verification. External pullup resistors are re-

quired during program verification.

DIP

Port 1: Port 1 is an 8-bit bidirectional I/O port with

internal 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 externally pulled low will source current

(I , on the data sheet) because of the internal pull-

ups.

In addition, Port 1 serves the functions of the follow-

ing special features of the 87C51FB/FC:

Port 1 receives the low-order address bytes during

EPROM programming and verifying.

Port 2: Port 2 is an 8-bit bidirectional I/O port with

internal 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 externally pulled low will source current
