描述 Description

The high-performance Microchip picoPower? AVR? RISC-based CMOS 8-bit microcontroller combines 32 KB ISP Flash memory with read-while-write capabilities, 1 KB EEPROM, 2 KB SRAM, 69 general purpose I/O lines, 32 general purpose working registers, JTAG interface for boundary-scan, on-chip debugging support, and programming, complete on-chip LCD controller with internal contrast control, three flexible timer/counters with compare modes, internal and external interrupts, serial programmable USART, universal serial interface (USI) with start condition detector, an 8-channel 10-bit A/D converter, programmable watchdog timer with internal oscillator, SPI serial port, and five software selectable power saving modes. The device operates between 1.8-5.5 volts.By executing powerful instructions in a single clock cycle, the device achieves throughputs approaching one MIPS per MHz, balancing power consumption and processor speed.
