Microchip has introduced a memory-segregated microcontroller (MCU) that it says can eliminate the need to store programs on separate chips in a multiparty design. Microchip's dsPIC digital signal controllers (DSCs) and PIC24H microcontrollers (MCUs) are claimed to be the first 16-bit devices with advanced memory security features that allow collaborative sharing of memory, interrupts and peripherals on a single chip, without compromising individual intellectual property (IP). In embedded applications, OEMs, design houses and software vendors face some critical IP protection issues while collaborating on system designs to achieve end-product customisation. According to Microchip, its CodeGuard security can eliminate these concerns by enabling OEMs to separate three segments of on-chip memory - the Boot Segment, Secure Segment and General Segment - with tiered levels of security. CodeGuard security is now being offered, at no additional charge, on the following Microchip devices: all PIC24H MCUs; all dsPIC33 DSCs; dsPIC30F5011/5013; dsPIC30F6010A/6011A/6012A/6013A/6014A/6015.
