| For Communications Equipment MN195001 Single-Chip Fax Engine LSI Overview The MN195001 reduces to a single chip CPU functions related to facsimile control, peripheral device control functions, and modem functions. The last include complete fax/modem support for the ITU-T G3 recommandations V.29, V.27ter, and V.21 Channels 1 and 2. The MN195001 consists of the following blocks: digital signal processor (DSP), facsimile peripheral circuits, analog circuits, DTE interface, clock generator, and dualport RAM. Changing the contents of an external ROM tailors the chip for a wide variety of facsimile applications. Features Digital signal processor (DSP) block * Micro ROM: 4096 x 32 bits * Data RAM: 512 x 16 bits x 2 sets * Machine cycle: 90 ns * Parallel multiplier: 16 bits x 16 bits x 32 bits * Arithmetic and logic unit (ALU): 32-bit Facsimile peripheral circuit block * Scanner/plotter interface * Two USART channels * Two motor control channels * One thermal head control channel * Programmable chip select Analog circuit block * Built-in 8-bit D/A converter, A/D converter, and filters DTE interface block * Built-in 8-bit I/O interface and serial interface Clock generator block * Sampling clock and baud rate clock generators Dual-port RAM block * 1024 x 8 bits Single 5 volt power supply Applications Facsimile equipment MN195001 Pin Assignment For Communications Equipment VIR VSEN UC0 UC1 UC2 UC3 A23
