The 16-bit dsPIC33E DSC and PIC24E MCU feature 536 Kbytes of flash and 52 Kbytes of RAM, combined with 60-MIPS performance and single-cycle multiply and accumulate. The devices also have a USB 2.0 OTG interface, a 15-channel DMA, with expanded motor-control, graphics, audio, and real-time embedded-control capabilities.
The ICs provide a user-selectable 13-cycle fixed latency or 9 to 13-cycle variable latency interrupt controller. An updated independent PWM mode supports multiple stepper motors and dead-time compensation. The devices operate on 3.0 to 3.6 V (with 1.8-V RAM data retention) from –40° to 85° C and are available in QFN64, TQFP64, TQFP144, BGA121, and LQFP144 packages. A new starter kit and 30 software libraries are available for these chips. (From $4.98 ea/10,000 — samples available now.)
