1 / 25 page 1/25 MTC20136 February 2004 ■ Dedicated controller for use with ADSL transceiver chips MTC20134, MTC20135 and MTC20455 – Performs ADSL control functions : – Initialization procedure – Line monitoring during operation – Rate adaptive modes ■ Supports the modem control interface protocol (CTRLE) ■ Embedded high speed ARM microcore ■ Glueless connection to MTC20135 and MTC20455 ■ Parallel or serial modem control interface (CTRLE) for glueless connection to management entities ■ Embedded UART ■ Supports code download ■ External Bus Interface for 8 and 16-bit FEPROM and 16-bit SDRAM ■ 144 pins PQFP DESCRIPTION The MTC20136 is a dedicated controller chip, spe- cifically designed to control operations of the ST- Microelectronics DynaMiTe chipset. The MTC20136 offers direct glueless interfaces to the MTC20135 and MTC20455 DMT/ATM transciever and implements a complete control interface for parameters and commands exchange between transceiver and system management. All real time ADSL-related functions (including EOC process- ing) are completely handled by the MTC20136. PQFP144 LFBGA160 ORDERING NUMBERS: Part number Package Temp.
