I found this list on the internet:

It was my understanding that the holtek does nothing more than demodulate the FSK-signal that contains the CLI. You therefore need a UART to receive the serial data.

Mavbe one of these has a buffer for the cli (MT series chips?). This way you can read a chip when the cli is complete.
