Easing System Level Integration Robust 3V Operation With operating voltages as low as 1.8V and up to 3.6V, PIC24 MCUs and dsPIC33 DSCs ensure robust operation such as: ■ POR/BOR/Watchdog Timer (WDT) ■ Support for temperatures up to 150°C ■ AEC-Q100 Grade 0 qualifi cation for automotive applications Enhanced Robustness with 5V Operation Microchip’s PIC24 MCU and dsPIC33 DSC portfolios include some families that operate up to 5V for increased noise immunity and robustness. Devices with 5V operation provide more dynamic range for signals and improved sensitivity. The 5V devices include additional features to ensure robust operation such as: ■ Backup system oscillator ■ Windowed watchdog timer (WWDT) ■ PWM with fault detection ■ Support for temperatures up to 150°C ■ AEC-Q100 Grade 0 qualifi cation for automotive applications Families with 5V Operation Flash Pins dsPIC33 “EV” DSC Family 32–256 KB 28–64 PIC24F “KM” and “KA” MCU Family 8–32 KB 20–44 Extreme Temperatures and AEC-Q100 Qualifi cation Many devices are also rated for operation up to 125°C or 150°C ambient temperature for the most extreme automotive and industrial applications, including AEC-Q100 Grade 0 qualification. Many target applications require operation in extreme environmental conditions. PIC24 MCUs and dsPIC33 DSCs have options for standard (85°C), extended temperature (125°C) and even high temperature up to 150°C. For automotive applications, our products support AECQ100 Grade 0 level qualification for 150°C support, especially helpful for under-the-hood systems.

Temperature Ranges Range Part Number Suffi x Standard −40 to 85°C -I Extended −40 to 125°C -E High −40 to 150°C -H 14 16-bit Embedded Control Solutions Safety Critical Applications and Class B Certifi cation PIC24 MCUs and dsPIC33 DSCs include integrated safety features to ease implementation of IEC 60830 compliance for Class B safety. The CRC provides a memory integrity check and many devices also include memory error correction. For example, dsPIC33 devices with Error-Correcting Code (ECC) include 2-bit error detection and single-bit error correction for enhanced reliability, completely transparent and real-time implementation. The memory also has read/write protection capability to protect sections of memory from code flow changes or interrupt vectors. You can establish zones that have different permissions, and you can define secure areas that should not be entered without the proper permissions. Products include a backup system oscillator for system redundancy as well as clock-fail detection. Features such as a windowed watchdog timer will detect and reset the MCU in event of code execution error, with a dedicated clock source independent of they system clock. A Dead- Man Timer (DMT), clocked from the main system clock, detects out of sequence execution. The PWMs include fault detection features and the CPU includes trap instructions and illegal opcode detection. The certified Class B software stack helps to simplify IEC 60830 regulatory compliance. This library routines integrate into the MCU application to test and verify the critical functionalities without affecting the end application. For more information, visit www.microchip.com/classb. Robust Package Options for IPC-9592B Some dsPIC33 “GS” devices are available with robust package options to help with operation in extremely noise environments. These packages make it easier to achieve IPC-9592B qualification. Options include a 28-pin μQFN (4 × 4 mm) or 28-pin μQFN (6 × 6 mm). These package options are designed to withstand temperature cycling as defined in IPC-9592B with over 700 cycles of −40°C/+125°C on thick high-layer count PCBs. www.microchip.com/hightemp www.microchip.com/classb
