www.DataSheet4U.com PRELIMINARY PRODUCT INFORMATION µPD789841, 789842 8-BIT SINGLE-CHIP MICROCONTROLLERS MOS INTEGRATED CIRCUIT The µPD789841 and µPD789842 are µPD789842 subseries products of the 78K/0S series. These microcontrollers incorporate an inverter control timer being suitable for controlling general-purpose inverters. The µPD78F9842, a product with on-chip flash memory which can operate on the same supply voltage as for masked ROM products and various development tools are also under development. Detailed descriptions of their functions, etc., are given in the following user's manuals. Be sure to read them for design purposes.
