UPD72002GB-11-3B4

The UPD72002GB-11-3B4 is designed as one kind of MPSC (multi-protocol serial controller) that is a general-purpose communication LSI equipped with two sets of bidirectional parallel/serial converter circuits for data communication. This device can be used with data communications equipment with a variety of communication modes such as the generally and widely used start-stop synchronization mode, and has a transmitter function to convert the parallel data output by a data terminal into serial data and transmit this data to a data transmission system.

Features of the UPD72002GB-11-3B4 are:(1)Two sets of parallel/serial circuits supporting three modes: start-stop synchronization, character synchroniza-tion, and bit synchronization modes;(2)DPLL (Digital Phase Locked Loop), baud rate generator, and crystal oscillation circuit for transmission/reception clock;(3)Many variations with power-saving features and small package size.

The absolute maximum ratings of the UPD72002GB-11-3B4 can be summarized as:(1)Supply voltage:0.5 to +7.0 V;(2)Input voltage:0.5 to VDD + 0.5 V;(3)Output voltage:0.5 to VDD + 0.5 V;(4)Operating temperature:40 to +85 °C;(5)Storage temperature:65 to +150 °C.

The electrical characteristics of the UPD72002GB-11-3B4 can be summarized as:(1)High-level input voltage: 3.3 to VDD+0.5 V;(2)Low-level input voltage: -0.5 to +0.6 V;(3)High-level output voltage: 0.7 VDD V;(4)Low-level output voltage: 0.45 V;(5)High-level input leakage current: 10 uA;(6)Low-level input leakage current: 10 uA;(7)High-level output leakage current: 10 uA;(8)Low-level output leakage current: 10 uA.
