Cover story
The new MCU families are also designed to make it easy to increase the security of an application, whether it is connected to the Internet or a standalone system. Microchip’s CodeGuard™ security Flash protection enables segmenting memory into boot and general segments to implement memory access restrictions. The Flash memory is configurable as One Time Programmable (OTP) via Microchip’s In-Circuit Serial Programming™ (ICSP) write inhibit feature that disables any further modification of the Flash through external programmers/debuggers. Together with these features, security can be further enhanced using Microchip’s CryptoAuthentication™ devices as a companion chip to add secure over- the-air updates and pre-provisioned cloud services. Lastly, the MCUs are supported by CryptoAuthLib, 16-bit bootloader, USB and many application libraries in MCC to significantly reduce development time and complexities.
The integrated hardware safety features of the PIC24F GU and GL families enable reliable operation in harsh environments through Flash Error Correction Code (ECC), Deadman Timer (DMT), Windowed
The latest family of PIC MCUs adds new hardware features that improve low power performance, code protection and reliable operation
Watchdog Timer (WWDT), Fail-Safe Clock Monitor (FSCM), Configurable High-Low Voltage Detect (HLVD) and Cyclic Redundancy Check (CRC). Capable of operating in harsh environments, the MCU families are
ideal for automotive, industrial and consumer applications. They feature an extended operating temperature of up to 125 °C, are automotive AEC Q100 Grade 1 qualified and have a diagnostic library for IEC 60730 (household appliances) Class B safety standards.
The PIC24F GU and GL MCUs are supported by Microchip’s MPLAB® development ecosystem including Microchip’s free MPLAB X Integrated Development Environment (IDE) and MPLAB Code Configurator. Other supporting boards include the PIC24F LCD and USB Curiosity Development Board, PIC24F LCD Curiosity Development Board, and the PIC24FJ512GU410 and PIC24FJ128GL306 General Purpose Plug-In Modules (PIMs) for the Explorer 16/32 Development Board. The PIC24F GL3 family with integrated LCD is available in 28-, 36-, 48- and 64-pin packages as small as 4x4 mm (uQFN). Memory ranges from 64 KB to 128 KB Flash and 8 KB RAM. The PIC24F GU4 / GL4 family with integrated LCD and USB is available in 48-, 64-, 80- and 100- pin packages with memory ranges from 128 KB to 512 KB Flash and 32 KB RAM. Prices start at $0.97 in high volume for the PIC24FJ64GL302-I/SS.
