UPD77112

DATA SHEET µPD77110, 77111, 77112 16-BIT FIXED-POINT DIGITAL SIGNAL PROCESSORS MOS INTEGRATED CIRCUIT DESCRIPTION The µPD77110, 77111, and 77112 are 16-bit fixed-point digital signal processors (DSPs). Compared with the µPD77016 family, these DSPs have improved power consumption and are ideal for batterypowered mobile terminals such as PDAs and cellular phones. Both mask ROM and RAM models are available. For details of the functions of these DSPs, refer to the following User’s Manuals: µPD77111 Family User’s Manual : To be available soon µPD7701X Family User’s Manual - Instructions: U13116E FEATURES z Instruction cycle (operating clock) µPD77110 : 15.3 ns MIN (65 MHz MAX) 13.3 ns MIN (75 MHz MAX) (Operating voltage and ambient temperature are limited.) µPD77111 : 13.3 ns MIN (75 MHz MAX) µPD77112 : 13.3 ns MIN (75 MHz MAX) z Memory Internal instruction memory µPD77110 : RAM 35.5K words × 32 bits µPD77111 : RAM 1K words × 32 bits Mask ROM 31.75K words × 32 bits µPD77112 : RAM 1K words × 32 bits Mask ROM 31.75K words × 32 bits Data memory µPD77110 : RAM 24K words × 16 bits × 2 banks External memory space 32K words × 16 bits × 2 banks µPD77111 : RAM 3K words × 16 bits × 2 banks Mask ROM 16K words × 16 bits × 2 banks µPD77112 : RAM 3K words × 16 bits × 2 banks Mask ROM 16K words × 16 bits × 2 banks External memory space 16K words × 16 bits × 2 banks The information in this document is subject to change without notice.
