Product details
Overview
MA330028 from Microchip Technology is a dsPIC33EP32GP502 16-bit digital signal controller in 28-pin SPDIP/SOIC/SSOP/QFN-S packages, operating at up to 70 MIPS (DC–70 MHz) across -40°C to +85°C, featuring 32 KB Flash, 4 KB RAM, dual 40-bit accumulators, 7.14 ns PWM resolution, and integrated op amps/ADC for motor control and power conversion.
For engineers reviewing the MA330028 datasheet, MA330028 pinout, MA330028 application, or MA330028 equivalent, this device supports high-precision timing-critical embedded control-especially where real-time PWM modulation, analog sensor interfacing, and CAN-based communication are required in compact industrial or automotive subsystems.
Technical Context
The MA330028 implements a dsPIC33E core with single-cycle MAC/MPY, hardware divide, and 32-bit multiply support, enabling deterministic execution of motor FOC or digital PFC algorithms. Its clock system includes a 1% internal oscillator, programmable PLLs, and Fail-Safe Clock Monitor for robust operation under voltage or frequency fault conditions.
It integrates three independent PWM pairs with per-edge dead-time control, CTMU for capacitive touch sensing, and six-channel 10-bit/12-bit ADC (1.1 Msps/500 ksps) with four S&H units-configured for simultaneous sampling of current/voltage feedback in BLDC or inverter topologies.
