| Microchip Announces PIC18F4XK20/2XK20 Microcontroller Family Microchip Technology has announced the first eight members of the PIC18F high-performance 8-bit microcontroller family to take advantage of Microchip's latest process technology. To control power consumption, the new 28-, 40- and 44-pin microcontrollers provide nanoWatt Technology features that include power-managed modes, an operating voltage range of 1.8V to 3.6V and efficient on-chip peripherals. Additionally, speeds of 16 MIPS (64 MHz) can be achieved at 3V operation from the internal oscillator, offering high performance while maintaining low power consumption. All of these features make the PIC18F4XK20/2XK20 family suited for general-purpose control, and a broad range of battery-operated or low-power applications. With the ever-increasing focus on portable applications that require reduced energy consumption and increased functionality, there is a clear need for embedded electronic intelligence that can do more with less. Microchip's new PIC18F4XK20/2XK20 family of high-performance 8-bit microcontrollers meets these needs head-on, not just with the levels of performance, but also at a cost-effective price point. Additionally, this new family continues Microchip's easy migration strategy, providing full code, pin-out and tool compatibility with the Company's comprehensive portfolio of 8-bit microcontrollers. Enhanced on-chip peripherals available with the PIC18F4XK20/2XK20 family include a software-selectable, precision 16 MHz internal oscillator with Phase Lock Loop (PLL); a Master Synchronous Serial Port (I2C /SPI) module with address masking; a four-channel, 10-bit Enhanced Capture/Compare Pulse-Width Modulation module with PWM steering capability; up to 14 10-bit Analog-to-Digital Conversion channels with a 1.2V fixed voltage reference; and dual rail-to-rail comparators. Other key features include: - Up to 64 Kbytes of Flash program memory; - Up to 3,936 bytes of RAM; - Up to 1,024 bytes of Data EEPROM memory; - Programmable Brown-Out Reset, with a software-enable option; - Extended WatchDog Timer; - Enhanced low-power Timer 1; - EUSART with LIN compatibility; - Two-speed oscillator start-up. write your comments about the article :: © 2007 Computing News :: home page |
