 The H6164P series is based on Helios's 8-bit MCU (JUPITER) and equipped with a powerful programmable sound generator (PSG) for processing sweet-sounding. Via proprietary system bus, the MCU (JUPITER) features efficient addressing register and memory timing control register (MTR) to access internal/external memory and I/O devices with appropriate timing.
   The H6164P is equipped with two high-resolution 16-bit D/A for audio output, which can support time-sharing mode for processing up to 64-poly sounds. There have been many firmware library of speech processing being implemented such as 4-bit ADPCM, 1-bit WFM, and so on. Since the H6164P has a built-in PSG, it also provides high quality standard MIDI playing library.
   The H6164P features 24 general purpose I/O pins. Each can be individually programmed to input or output mode, and with internal pull-up or not. Each I/O of port 0 can be programmed to select interrupt source and the interrupt signal can be falling or rising trigger.
   The H6164P features VCO and PLL to provide system clock. The frequency of the system clock is programmable up to 45 MHz. The device has two built-in 8-bit timers. Each timer is made up of an 8-bit up counter, 8-bit reload data, and pre-scaler. Usually, the timer can be used to configure speech sampling frequency. The H6164P also supports two device interfaces: one is 2-wired serial bus, and the other is 8-bit parallel MCU control interface. The H6164P acts as a slave device and is able to communicate with the external host controller by either of the two interfaces.
