MCUs Boast Of Extensive Power Management Options

The new PIC18FXX20 family consists of six PICmicro flash microcontrollers employing the company’s NanoWatt technology. The MCUs feature six enhanced “software controlled” power managed modes, power consumption as low as 0.1 µA in standby mode, and a wide operating voltage range of 2V to 5.5V making them well suited for battery managed applications. The devices offer up to 8K bytes of flash program memory, up to 512 bytes of RAM memory, 256 bytes of EEPROM memory, and an internal multi-frequency oscillator of up to 8 MHz. Additional features include a 10-bit A/D converter with up to 13 channels, an enhanced capture/compare/ PWM module (CCP) with one, two or four outputs with auto-shutdown and auto-restart, an addressable USART module supporting RS-485, RS-232 and LIN, a programmable 16-level low voltage detection module (PLVD), and programmable brown-out reset (PBOR). The PIC18FXX20 family is priced between $1.80 and $3.50 in volume quantities, depending on device, temperature range, package and operating voltage. MICROCHIP TECHNOLOGY, Chandler, AZ. (480) 792-7668.
