Chandler, Ariz. - Microchip Technology Inc. announced the expansion of its eXtreme Low Power (XLP) PIC microcontroller (MCU) portfolio. The latest family of eXtreme Low Power PIC MCUs offers double the flash memory and adds new security options.
Key features of the new PIC24F “GB4” family include an integrated hardware crypto engine with both one-time-programmable (OTP) and Key RAM options for secure key storage, up to 256 KB of Flash memory and a direct drive for segmented LCD displays, in 64-, 100- or 121-pin packages. OTP prevent overwriting keys, and Key RAM erases keys if power is lost. To allow the application’s Real-Time Clock to continue running when primary power is removed, a VBAT pin can be used to supply back-up power.
The MCUs also offer dual-partition Flash with Live Update capability, which allows the devices to hold two independent software applications, and permits the simultaneous programming of one partition while executing application code from the other.
These advanced features make the PIC24F “GB4” family well suited for industrial, computer, medical/fitness and portable applications that require secure data transfer and storage, and a long battery life, Microchip said.
“Securing your data is one of the key challenges in today’s Internet of Things world,” said Joe Thomsen, vice president of Microchip’s MCU16 Division, in a statement. “The combination of our XLP technology and encryption capabilities enables this new PIC24 ‘GB4’ family to increase the integrity of embedded data for a broad range of applications, without sacrificing power consumption.”
To protect embedded data, several Microchip Core Independent Peripherals (CIPs) that run without the CPU are integrated into the PIC24F “GB4” family. The fully featured hardware crypto engine includes support for the AES, DES and 3DES standards. A Random Number Generator is used for generating random keys for data encryption, decryption and authentication, enabling a higher level of security, said Microchip.
