  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.

With Instruction / Data Local Memory bus (ILM/DLM) built in CPU, the NX1 can run 1.57 DMIPS per MHz and up to 50+ DMIPS @ 32MHz. In addition, the dual clock design let customers switch between fast / slow clocks for achieving the best power consumption and performance ratio, or may employ 32.768KHz X’tal oscillator for time-keeping applications.

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.

There are various useful features inside the NX1 series: Three sets of 16-bit Timers; 8-ch H/W PWM-IO pins, which provide complimentary outputs (with dead zone generator) and capture feature; 8-channel, 12-bit SAR ADC with MIC pre-amplifier & AGC / PGA that supports differential MIC input; 14-bit DAC + 1.5-watt Push-Pull power amplifier to drive speaker directly; independently configurable GPIO per pin with alternate functions; IR TX that supports 38KHz / 57KHz / 125KHz / 500KHz carrier for Infrared or QFID applications; SPI0 for SPI flash control, powered by embedded optional 3.3V / 1.8V LDO, which supports single/dual/quad I/O mode with XIP (eXecute In Place) capability; SPI1 for 2.4GHz RF module or other SPI devices; SDHC 2.0-compliant memory card; I2C H/W interface and UART TX / RX for serial communication.

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.

Various package forms are available for the NX1 series: Dice, SOP-16, SSOP-24, LQFP-32, LQFP-48, LQFP64 and the innovative SOP-8 / SOP-16 MCP (Multi-Chip Package), where SPI flash is stacked inside for applications that require small footprints.
