    Analog multiplexer 3:144

    godmode_3502096

      I have designed an SWD debugger interface multiplexer that multiplexes 3 SWD signals (VREF, SWDIO, SWCLK) to 48 ports.
      I use it on production to program or debug one of 48 devices using only one SWD debugger (Segger J-Link).
      The PCB consist of six 1:8 analog multiplexers driven by STM32 Cortex-M0.

       

      I would like modernize the design and use one of Cypress PSOC equipped with AMuxHW (Analog Hardware Multiplexer).
      Can somebody point me at right direction which Cypress's device should I use to multiplex 1 to 48 SWD interfaces (3:144 line multiplex)?
