UPD750008 Datasheet | NEC

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 k Hz) - 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 The µPD750004, µPD750006, µPD750008, µPD750004(A), µPD750006(A), and µPD750008(A) differ only in quality grade. In this manual, the µPD750008 is described unless otherwise specified. Users of other than the µPD750008 should read µPD750008 as referring to the pertinent product. When the description differs among µPD750004, µPD750006, and µPD750008, they also refer to the pertinent (A) products. µPD750004 → µPD750004(A), µPD750006 → µPD750006(A), µPD750008 → µPD750008(A) The...
