The '''M382''' is a custom gate array IC designed by [[Brian Rhodefer]] | The '''M382''' is a custom gate array IC designed by [[Brian Rhodefer]] used in 11000-series plug-ins, where it serves three functions: | ||
* [[ACVS|Analog Control Voltage System (ACVS)]] management. Once the M382 has been given the values for each of the ACVS voltages, it takes care of sending data to the DAC and controlling the sample-and-hold circuits. The M382 periodically refreshes the sample-and-hold voltages without any involvement of the main microprocessor. | * [[ACVS|Analog Control Voltage System (ACVS)]] management.
