Power management takes
controllers to new lows
Microchip's new PIC18FXX20 family of six PICmicro Flash microcontrollers gives complete control of system power consumption
Designed using Microchip's unique nanowatt technology with advanced PMOS electrically erasable cell (PEEC) process technology, circuit design and manufacturing techniques, the PIC18FXX20 family features power consumption as low as 0.1uA in standby mode and an operating voltage range from 2 to 5.5V.

LDO cuts power for long-term standby
Power-saving low-dropout regulator is ideal for applications requiring long battery runtimes and high tolerance for input-voltage variations
A flexible clock system with six "software controlled" power-managed modes supports code execution from a real-time clock base and control of execution speed.
Additional features include a low-current watchdog timer, a two-speed start-up from a reset or sleep mode and a fail-safe clock monitor to detect external clock failures.
Others include a 10bit analogue-to-digital convertor with up to 13 channels, an enhanced capture/compare/PWM module with one, two or four outputs with auto-shutdown and auto-restart, an addressable USART supporting RS485, RS232 and LIN, a programmable 16-level low-voltage detection module and programmable brownout reset.
The devices offer up to 8Kbyte of Flash program memory, up to 512byte of RAM, 256byte of EEPROM, and an internal multifrequency oscillator up to 8MHz.
Pin- and code-compatible with Microchip's current 18-, 28- and 40-pin portfolio, the devices feature in-circuit serial programming that allows them to be programmed after being placed in a circuit board.
The devices are supported by Microchip's MPLAB in-circuit debugger (ICD2) development tool, a powerful, low-cost run-time tool that offers in-circuit Flash programming and debugging from the graphical user interface.
Available packages include 18-pin PDIP and SOIC, 20-pin SSOP, 28-pin PDIP, SOIC, quad flat no-lead (QFN) and 44- and 40-pin PDIP, TQFP, QFN packages.
