DATA SHEET MOS INTEGRATED CIRCUIT µPD75P068 4 BIT SINGLE-CHIP MICROCOMPUTER The µPD75P068 is produced by replacing the internal mask ROM of the µPD75068 with a one-time PROM in which data can be written once. The following user's manual describes the details of the functions of the µPD75P068. Be sure to read it before designing an application system. µPD75068 User's Manual: IEU-1366 FEATURES • Compatible with the µPD75068 • Can be replaced with the µPD75068 containing mask ROM on a full-production basis. • • • • • Internal one-time PROM: 8064 words × 8 bits Internal RAM: 512 words × 4 bits Internal pull-up resistors can be specified with software: Ports 0 to 3 and 6 N-ch open-drain input-output: Ports 4 and 5 Can operate at low voltage: VDD = 2.7 to 6.
