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 high speed 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 µPD750008.
A built-in one-time PROM product, µPD75P0016, is also available. It is suitable for small-scale production and evaluation of application systems.

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 channels)
• Can be easily substituted for the µPD75008 because this product succeeds to the functions and instructions of the µPD75008.

APPLICATIONS
• µPD750004, µPD750006, and µPD750008 Cordless telephones, radio devices, audio products, and home electric appliances
• µPD750004(A), µPD750006(A), and µPD750008(A) Electrical equipment for automobiles
