Low Energy MCUs That Provide {Hardware} Security and Code Safety


  • The low energy MCUs help in delivering higher show of data by way of animations and include all kinds of security measures
  • They’re able to working in harsh environmental circumstances and superb for automotive, industrial and client functions

System builders of battery-powered and different power-conscious designs with and with out LCDs can now simply add an array of progressive options utilizing a brand new line of PIC® eXtreme Low Energy (XLP) microcontrollers (MCUs) from Microchip Expertise.

Full of 14 sorts of Core Impartial Peripherals (CIPs) that function exterior the Central Processing Unit (CPU) for energy financial savings, the PIC24F GU and GL families of MCUs function the CIP referred to as LCD with Autonomous Animation.

Able to working in harsh environments, the MCU households are perfect for automotive, industrial and client functions.

Most show functions these days contain a couple of animations like periodically alternating between shows and blinking of pixels to point operation. Through the use of an built-in LCD driver with autonomous animation, builders can offload most of those easy animation routines from the CPU, permitting animation even in idle or sleep modes to save lots of energy. To help in rapidly designing such show interfaces, the brand new MCUs include MPLAB® Code Configurator (MCC) help. This graphical programming atmosphere helps LCD designer remove the time-consuming activity of mapping the pins and segments.

Strengthened Safety

The brand new MCU households are additionally designed to make it straightforward to extend the safety of an software, whether or not it’s linked to the Web or a standalone system. Microchip’s CodeGuard™ safety Flash safety allows segmenting reminiscence into boot and normal segments to implement reminiscence entry restrictions. The Flash reminiscence is configurable as One Time Programmable (OTP) through Microchip’s In-Circuit Serial Programming™ (ICSP) write inhibit function that disables any additional modification of the Flash by way of exterior programmers/debuggers.

Along with these options, safety could be additional enhanced utilizing Microchip’s CryptoAuthentication™ gadgets as a companion chip so as to add safe over-the-air updates and pre-provisioned cloud companies. Lastly, the MCUs are supported by CryptoAuthLib, 16-bit bootloader, USB and lots of software libraries in MCC to considerably cut back improvement time and complexities.

The built-in {hardware} security options of the PIC24F GU and GL households allow dependable operation in harsh environments by way of:

  • Flash Error Correction Code (ECC)
  • Deadman Timer (DMT)
  • Windowed Watchdog Timer (WWDT)
  • Fail-Protected Clock Monitor (FSCM)
  • Configurable Excessive-Low Voltage Detect (HLVD)
  • Cyclic Redundancy Test (CRC)

The MCUs function an prolonged working temperature of as much as 125 levels Celsius, are automotive AEC Q100 Grade 1 certified and have a diagnostic library for IEC 60730 (family home equipment) Class B security requirements.

“The newest household of PIC MCUs provides new {hardware} options that enhance low energy efficiency, code safety and dependable operation in functions throughout a number of segments,” stated Joe Thomsen, vice chairman of Microchip’s MCU16 enterprise unit. “This scalable household of gadgets allow functions from cloud-connected low-power IoT nodes and sensor programs to automotive, client and industrial automation functions and helps builders simply add shows, robustness and safety to their designs.”

Growth Assist

The PIC24F GU and GL MCUs are supported by Microchip’s MPLAB® improvement ecosystem together with Microchip’s MPLAB X Built-in Growth Atmosphere (IDE) and MPLAB Code Configurator. Different supporting boards embody the PIC24F LCD and USB Curiosity Growth Board, PIC24F LCD Curiosity Growth Board, and the PIC24FJ512GU410 and PIC24FJ128GL306 Common Objective Plug-In Modules (PIMs) for the Explorer 16/32 Growth Board.

The PIC24F GL3 household with built-in LCD is obtainable in 28-, 36-, 48- and 64-pin packages as small as 4×4 mm (uQFN). Reminiscence ranges from 64 KB to 128 KB Flash and eight KB RAM. The PIC24F GU4 / GL4 household with built-in LCD and USB is obtainable in 48-, 64-, 80- and 100-pin packages with reminiscence ranges from 128 KB to 512 KB Flash and 32 KB RAM.
