DSPIC33EP64MC204-E/PT

DSPIC33EP64MC204-E/PT is a Microchip dsPIC33EP 16-bit digital signal controller from the MC motor-control subfamily, in a 44-lead TQFP (10x10 mm) — for BLDC and PMSM drives and digital power stages where DSP math and MCU peripherals must share one die. The core runs at 60 MIPS with 64 KB of flash and 8 KB of RAM, exposes 35 I/O, and operates from 3.0 V to 3.6 V, so the control loop fits in one mid-density controller instead of a DSP-plus-MCU pair. The E code is the extended -40 to +125°C grade, covering under-hood and industrial ambients. The code appeared in an ic.net.cn buy request for 5,000 pieces on scan day, evidence of current production demand. Selection advice: the /PT code is the TQFP-44 tray form — with no T suffix this is not the tape-and-reel code, so confirm the packing form your line expects; and check the MC204 peripheral mix in the DS70000657 family table against your drive topology, because pin count, not flash size, usually decides between the MC204 and its larger siblings.
