The VLN1M(NX11M) series is a 32-bit MCU based high-quality speech/MIDI processor, which is specially designed for customers to innovate with advanced DSP power. It is embedded with OTP (One Time PROM) for mass production, such that no mask is required while MOQ / Lead Time are kept minimized.
The VLN1M(NX11M) series consists of several derivatives with respect to ROM (OTP), RAM, I/O and functions. With memory-mapped architecture, the VLN1M(NX11M) can address up to 16MB space that includes memory, register files, peripheral and SPI flash storage (including instruction/data modes). SBC (Sub-Band Coding) is achieved with greatly enhanced quality & much less memory size compared against traditional ADPCM coding due to the incorporation of efficient DSP algorithms as well as the upgrade of H/W spec. Via the high performance of 32-bit MCU, the S/W-based MIDI synthesizer can reach more than 16-ch polyphonic channels. All data including SBC / MIDI files, wavetable timbres, XIP codes and general user data, can be accessed from the external SPI flash.
