Flash MCUs ease serial to USB migration
Flash PIC microcontrollers provide certified Full-Speed USB 2.0 connectivity for 12Mbit/s data-transfer rates and 12MIPS processing performance.
Microchip has released two new Flash PIC microcontrollers, the PIC18F2450 and PIC18F4450, with certified Full-Speed USB 2.0 connectivity for 12Mbit/s data-transfer rates and 12MIPS (48MHz) processing performance. Combined with a wide variety of on-chip peripherals, nanoWatt Technology power management, and self-programmable Flash memory, these features provide a complete solution for designers working with USB in industrial, medical and many other embedded applications. Many USB-capable microcontrollers are optimised for applications in PC peripherals and consumer markets, rather than for embedded designs.
Microchip's USB PIC microcontroller family makes the benefits of Full-Speed USB available to a broader range of embedded applications that operate in harsh environments and only occasionally connect to personal computers.
Some applications that may benefit from these new USB PIC microcontrollers include industrial data-logging, timing and analysis tools; battery-powered handheld devices; and fire, security, home-automation and back-up (UPS) systems.
The two new USB PIC microcontrollers feature 16Kbyte of self-programmable enhanced Flash memory, which allows field upgrades for end applications via the USB port.
Microchip's advanced Flash technology provides high endurance of up to 100,000 erase/write cycles and data retention of more than 40 years.
One area of concern for most USB-application designers is the quantity and quality of available firmware support.
Microchip has an extensive set of libraries for the most common application classes, including the Human Interface Device (HID), Communication Device Class (CDC) and custom drivers.
In addition, Microchip has published application note AN956, 'Migrating applications to USB from RS232 UART with minimal impact on PC software', for migrating legacy serial applications.
The new USB PIC microcontrollers are also supported by Microchip's world-class development systems, including: MPLAB integrated development environment (IDE), MPLAB C18 C compiler, MPLAB ICD 2 in-circuit debugger, MPLAB ICE 2000 and MPLAB ICE 4000 in-circuit emulators and MPLAB PM3 universal device programmer.
In addition, the PICDEM Full-Speed USB demo board (DM163025) assists development with this family's advanced USB features.
The new USB PIC microcontrollers are available now for sampling and volume production.
