32-bit MCU with Sub-Band Coding & 16-ch MIDI
The VLN3M(NX13M) 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.
There are various useful features inside the VLN3M 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 + 1.3-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.
Various package forms are available for the VLN3M series: the innovative SOP-16 MCP (Multi-Chip Package), where SPI flash is stacked inside for applications that require small footprints.
