PIC24EP64GP204-I/ML - 70 MIPS 16-Bit MCU | Microchip Technology
The Microchip Technology PIC24EP64GP204-I/ML is a 16-bit PIC24E general-purpose microcontroller with a 70 MIPS core, 64 KB of internal Flash memory, 8 KB of SRAM, and a 44-pin QFN package measuring 8 mm by 8 mm. It is designed for industrial embedded systems that require deterministic control performance and integrated analog resources. The -I/ML ordering option identifies the industrial-temperature, 44-QFN configuration and operates from 3 V to 3.6 V.
A microcontroller is a programmable semiconductor that combines a processor core, memory, and peripherals on one integrated circuit. The PIC24E family follows the hierarchy of microcontroller, embedded processor, and general-purpose MCU. These devices execute firmware for real-time control, data acquisition, communications, and human-machine interfaces. The PIC24EP64GP204-I/ML belongs to Microchip's high-speed 70 MIPS PIC24E family, combining code density with specialized analog and timing peripherals.
Key features include a 16-bit CPU capable of 70 MIPS, 64 KB of Flash program memory, and 8 KB of SRAM. Its integrated analog capabilities include an ADC, CTMU, operational amplifiers, and a Peripheral Trigger Generator. The CTMU supports accurate measurement and stimulus functions, while the operational amplifiers reduce the need for external analog front-end components. The Peripheral Trigger Generator provides deterministic peripheral timing for applications requiring precise event sequencing.
The MCU combines a 70 MIPS processing core with an 8-bit data bus and supports operation from a 3 V to 3.6 V supply. Its industrial temperature rating is -40 °C to +85 °C. These characteristics make it suitable for control systems, sensor measurement, motor control, industrial instrumentation, and connected embedded equipment where a compact package and integrated analog functions reduce board complexity.
Typical uses include digital power converters, motor-control systems, data acquisition units, industrial sensors, programmable logic controllers, and compact control boards. In a current-control design, the ADC and CTMU can acquire analog measurements, while the integrated operational amplifiers can condition nearby signals. The Peripheral Trigger Generator helps coordinate timer-driven actions, and the 70 MIPS core provides computational headroom for control algorithms, communications, and supervisory logic.
PCB design should preserve the manufacturer's recommended decoupling and exposed-pad land pattern. Place the supply bypass capacitors close to their associated power pins, route sensitive analog inputs away from fast-switching nodes, and connect the exposed thermal pad to the recommended ground plane. Verify operation across the complete 3 V to 3.6 V supply range and the -40 °C to +85 °C environmental range before production release.
This page consolidates the exact device identity, package information, memory configuration, performance figures, replacement analysis, and application-oriented design guidance. It also distinguishes the verified industrial 44-QFN variant from temperature-grade and package-format options that cannot be treated as unconditional PCB drop-ins.
