SNC109 is a single-channel voice synthesizer IC with PWM direct drive circuit. It built-in a 4-bit tiny controller with one 4-bit input port, two 4-bit I/O ports. By programming through the tiny controller in SNC109, user’s varied applications including voice section combination, key trigger arrangement, output control, and other logic functions can be easily implemented.
The SONiX SNC109 is a single-channel speech synthesis integrated circuit designed for applications requiring voice output. It features an internal 4-bit microcontroller that allows users to program voice combinations, key triggers, and logic functions directly within the chip.
Key specifications include a system clock of 2MHz, operating voltage ranging from 2.4V to 5.1V, and a capacity for up to 61 seconds of voice data at a 6kHz sample rate. The device contains 184K*10 bits of ROM for program and voice storage, along with 64 nibbles of RAM.
