DATA SHEET MOS INTEGRATED CIRCUIT µPD750104,750106,750108,750104(A),750106(A),750108(A) 4 BIT SINGLE-CHIP MICROCONTROLLER The µ PD750108 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 µ PD750108 is produced by replacing the main system clock oscillator of the µPD750008 with an RC oscillator, enabling operation at a relatively low voltage of 1.8 V. In addition, it is best suited to applications using batteries. The µPD750108(A) has a higher reliability than the µ PD750108. A built-in one-time PROM product, µ PD75P0116, 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 µPD750108. Be sure to read it before designing application systems. µPD750108 User’s Manual: U11330E FEATURES Built-in RC oscillator Enables the immediate start of processing after the release of standby mode Capable of low-voltage operation: VDD = 1.8 to 5.5 V Internal memory Program memory (ROM) : 4,096 × 8 bits ( µ PD750104 and µ PD750104(A)) : 6,144 × 8 bits ( µ PD750106 and µ PD750106(A)) : 8,192 × 8 bits ( µ PD750108 and µ PD750108(A)) Data memory (RAM) : 512 × 4 bits Function for specifying the instruction execution time (useful for saving power) 4 µ s, 8 µs, 16 µs, 64 µ s (when operating at 1.0 MHz) 2 µs, 4 µ s, 8 µ s, 32 µs (when operating at 2.0 MHz) 122 µ s (when o...
