Product details
Microchip Technology's MEC1404-NU reimagines Embedded - Microcontrollers - Application Specific for smart grid and power conversion applications. This application-specific microcontroller integrates advanced PWM generation with high-resolution ADC capabilities, enabling precise control of power electronics.Optimized for Keyboard and Embedded Controller implementations, the device features hardware-based overcurrent protection with 50ns response time. The integrated sigma-delta modulators enable direct sensorless motor control.The MIPS32® M14K™ core includes dedicated trigonometric acceleration units. The parallel execution pipelines achieve 95% duty cycle accuracy at 100kHz switching frequencies.Supporting External Program Memory options, the flash memory incorporates shadow registers for bumpless firmware updates. The dual-plane architecture allows live updates during continuous operation.The 128KB memory implements deterministic access timing for control loops. The dual-port architecture allows simultaneous access from CPU and PWM units.With I²C, LPC, SMBus, SPI, UART connectivity, the device supports EtherCAT POWERLINK protocols. Each communication peripheral includes reinforced isolation meeting IEC 61800-5-1 standards.The 106 configurable ports feature 12-bit DAC outputs for analog control. Programmable dead-time insertion prevents shoot-through in bridge configurations.Operating from 1.71V ~ 3.465V inputs, the power architecture withstands 100V transients. The integrated gate drivers support SiC and GaN power devices.Certified for 0°C ~ 70°C operation, the package uses direct-bonded copper substrates. Thermal impedance is minimized for high-current applications.The Surface Mount option supports press-fit assembly for high-power PCBs. The package design accommodates thick copper layers for heat dissipation.Available in 128-TQFP format, the package includes Kelvin sense connections. The low-inductance design minimizes switching losses at high di/dt rates.Supplied in 128-VTQFP (14x14) configuration, each unit includes power cycling test reports. Production testing includes 100% burn-in at maximum junction temperature.
