ELM621P中文资料ELM数据手册PDF规格书

Description

The ELM621 is a serially controlled, three bit parallel I/O port in an 8 pin package. The high level of integration employed means that very few external components are required in order to construct a fully functional circuit with this IC.

Features

• Low power CMOS design - typically 1mA

• High speed (9600 baud) RS232 communications

• Standard ASCII commands and responses

• 16 byte receive buffer

• Switchable pullup resistance

• Minimum of external components required

• External reset input

• High current drive outputs - up to 25 mA

Applications

• Home automation monitoring and control

• Robotics

• Security monitoring

• IC programmers
