DSPIC30F4012T-30I/ML

Microcontrollers Overview

The dsPIC30F4012T-30I/ML is a 16-bit Digital Signal Controller (DSC) from the Microchip dsPIC30F family. It features a 1-core architecture with a maximum clock frequency of 30 MHz. The device includes 16K instruction words (48 KB equivalent) of Flash program memory and 512 words of Data EEPROM. It operates within a voltage range of 2.5 V to 5.5 V and is housed in a QFN-28 package.

Microcontrollers Feature Summary

• Integrates a 16-bit DSP core with a 24-bit instruction set for high-performance signal processing and control tasks.
• Supports Enhanced In-Circuit Serial Programming (ICSP) via an on-chip programming executive for efficient code verification and writing.
• Includes dedicated executive code memory reserved for programming and debugging functions, separate from user application space.

Microcontrollers Applications

• Implementation of T-S fuzzy controllers for shunt active power filter systems
• Development of third-party tool programming specifications for dsPIC30F devices
• In-circuit serial programming and bulk erase operations using high-voltage methods

Microcontrollers Procurement Notes

Verify that the ordering suffix 'T' corresponds to the specific tape-and-reel packaging configuration required for your assembly line. Confirm that the '30' designation aligns with the 30 MHz speed grade needed for your timing constraints. Ensure the 'I' temperature rating matches your environmental operating requirements. Cross-reference the ML package type with your PCB footprint design to guarantee physical compatibility during procurement.

Microcontrollers Selection Notes

Select this component when a 16-bit DSC with 16K instruction word capacity and integrated Data EEPROM is required. The 30 MHz speed grade suits applications needing moderate processing throughput without excessive power consumption. The QFN-28 package is suitable for compact designs where surface-mount technology is preferred over through-hole options. Verify peripheral availability against specific application needs such as PWM or ADC requirements not detailed in the programming specification.

Microcontrollers Part Context

This device belongs to the dsPIC30F series, which combines digital signal processing capabilities with microcontroller flexibility. The series utilizes a 24-bit instruction word architecture and supports up to 144 Kbytes of code memory across various models. The dsPIC30F4012 specifically offers a mid-range memory configuration within this family, balancing processing power and storage for general-purpose control applications.

Microcontrollers Replacement Considerations

Consult the official dsPIC30F datasheet for pin-compatible alternatives within the same family. Devices like the dsPIC30F4011 or dsPIC30F4013 may serve as substitutes if memory size differences are acceptable. Verify that any replacement maintains the required 30 MHz performance and QFN-28 package form factor.
