It runs at 70 MIPs, which means a 3.3 V supply and a 28-SOIC footprint can handle a field-oriented motor control or a digital power conversion loop without an external DSP. ## Peripheral set for the motor-drive engineer The on-chip Motor Control PWM module with complementary outputs, dead-time insertion, and fault handling is the headline feature for a drive design. DMA offloads the ADC readings and PWM updates without core intervention — that is what keeps the control loop deterministic at 70 MIPs. The 6-channel ADC (10-bit or 12-bit resolution) samples current-sense resistors or shunt amplifiers; the QEI interface reads an incremental encoder directly. ## Temperature grade and field-swap reality It lives in a motor drive cabinet, an outdoor pump controller, or a factory-automation node — not an under-hood engine bay. If you are swapping one in the field, a hot-air station is safer than a soldering iron on all 28 legs, but it is doable with care. ## Lifecycle – no LTB worry here Microchip lists the DSPIC33EP64MC202-I/SO as an active product. The dsPIC33EP family has been a workhorse for a decade; the die and package are mature, so PCN risk is low. If you need a second-source conversation, the PIC24FJ256GA106-I/MR is a 16-bit PIC24 with similar peripherals but a different core (no DSP engine) and a larger package — not a pin-drop replacement, but a functional alternative for a non-DSP control task.","metaTitle":"DSPIC33EP64MC202-I/SO dsPIC33EP 16-bit MCU, 70 MIPs","metaDescription":"Microchip dsPIC33EP64MC202-I/SO 16-bit DSC, 70 MIPs, 64KB Flash, 4Kx16 RAM, 28-SOIC, -40°C to 85°C.","metaKeywords":null},"attributes":{"series":"dsPIC™ 33EP","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Speed":"70 MIPs","Series":"dsPIC™ 33EP","Package":"Tube","RAM Size":"4K x 16","Core Size":"16-Bit","Peripherals":"Brown-out Detect/Reset, DMA, Motor Control PWM, POR, PWM, WDT","Connectivity":"I²C, IrDA, LINbus, QEI, SPI, UART/USART","Mounting Type":"Surface Mount","Number of I/O":"21","Core Processor":"dsPIC","Package / Case":"28-SOIC (0.295\\\", 7.50mm Width)","Data Converters":"A/D 6x10b/12b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Program Memory Size":"64KB (22K x 24)","Program Memory Type":"FLASH","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"28-SOIC","Voltage - Supply (Vcc/Vdd)":"3V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.13","priceTiers":[{"qty":1,"price":"$3.13000","currency":"USD"},{"qty":25,"price":"$2.88000","currency":"USD"},{"qty":100,"price":"$2.60000","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/a6ba7ace9d87c6b29e759cc334e0bea3.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/DSPIC33EP64MC202-I%2FSO/alternatives.json"},"ai":{"faq":[{"question":"Is DSPIC33EP64MC202-I/SO an active product or nearing end of life?","answer":"It is safe to design in for production runs without near-term obsolescence risk."},{"question":"What are the key differences between DSPIC33EP64MC202-I/SO and the larger memory DSPIC33EP256MC202-I/SO?","answer":"The 256 KB Flash variant (DSPIC33EP256MC202) quadruples the program memory and doubles the RAM, but the core speed, peripheral set, pinout, and package are identical.
