Hardware transport-stream demultiplexor Parallel/serial input DES and DVB descramblers 32 PID support. Integrated peripherals 2 UARTs, 2 SmartCards, I C controller, 3 PWM outputs, 3 capture timers Modem support 44 bits of programmable I/O IR transmitter/receiver.
  • Page 9 SERVICE MANUAL 3. Architecture overview The figure below shows the architecture of the Sti5518. This chapter gives a brief overview of each of the functional blocks of the STi5518. 4. STi5518 functional modules a. Central processor The STi5518 Central Processing Unit is a ST20C2+ 32-bit processor core. It contains instruction processing logic, instruction and data pointers, and an operand register.
