NX1 Series

NX1

32-bit MCU with Sub-Band Coding & 16-ch MIDI

The NX1 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 NX1 series consists of several derivatives with respect to ROM (OTP), RAM, I/O and functions. With memory-mapped architecture, the NX1 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.

NX1 VR & QFID

Except developing by C language at NYIDE environment, which provides customers with more controllability over complicated projects. Moreover, The NX1 series brings Q-Code (High-level programming) to 32-bit MCU, which provides customers with an easy-to-use, highly productive development environment to cope with the importance of in-time product concept realization. The multi-purpose NX_Programmer (USB-2-Serial adaptor) H/W provides customers with various functionalities: program code debugging @ ICE, prototype demo @ FDB (Flash Demo Board) and mass production @ OTP. Besides, NX_Programmer can also provide ICP (In-Circuit Programming) function to program SPI flash for customers to fabricate PCBA in advance.
