DATA SHEET MOS INTEGRATED CIRCUIT µPD750004,750006,750008,750004(A),750006(A),750008(A) 4 BIT SINGLE-CHIP MICROCONTROLLER The µPD750008 is one of the 75XL series 4-bit single-chip microcontrollers, which provide data processing capability equal to that of an 8-bit microcontroller. The µPD750008 is an advanced model of the µPD75008. It features an enhanced CPU function and enables highspeed operation at a low voltage of 2.2 V. It can be substituted for the µPD75008. In addition, it is best suited to applications using batteries. The µPD750008(A) has a higher reliability than the µ PD750008. A built-in one-time PROM product, µ PD75P0016, is also available. It is suitable for small-scale production and evaluation of application systems. The following user’s manual describes the details of the functions of the µPD750008. Be sure to read it before designing application systems. µPD750008 User’s Manual: U10740E FEATURES Capable of low-voltage operation: VDD = 2.2 to 5.5 V Internal memory Program memory (ROM) : 4096 × 8 bits (µPD750004 and µPD750004(A)) : 6144 × 8 bits (µPD750006 and µPD750006(A)) : 8192 × 8 bits (µPD750008 and µPD750008(A)) Data memory (RAM) : 512 × 4 bits Function for specifying the instruction execution time (useful for high-speed operation and saving power) 0.95 µs, 1.91 µs, 3.81 µs, 15.3 µs (when operating at 4.19 MHz) 0.67 µs, 1.33 µs, 2.67 µs, 10.7 µs (when operating at 6.0 MHz) 122 µs (when operating at 32.768 kHz) Enhanced timer function (4 cha...
