Product Details
| Overview The ATmega164A/164PA/324A/324PA/644A/644PA/1284/1284P is a low-power CMOS 8-bit microcontroller based on the AVR enhanced RISC architecture. By executing powerful instructions in a single clock cycle, the ATmega164A/164PA/324A/324PA/644A/644PA/1284/1284P achieves throughputs approaching 1 MIPS per MHz allowing the system designer to optimize power consumption versus processing speed. Features • High-performance, Low-power AVR® 8-bit Microcontroller • Advanced RISC Architecture – 131 Powerful Instructions – Most Single-clock Cycle Execution – 32 x 8 General Purpose Working Registers – Fully Static Operation – Up to 20 MIPS Throughput at 20 MHz – On-chip 2-cycle Multiplier • High Endurance Non-volatile Memory segments – 16/32/64/128K Bytes of In-System Self-programmable Flash program memory – 512B/1K/2K/4K Bytes EEPROM – 1/2/4/16K Bytes Internal SRAM – Write/Erase Cycles: 10,000 Flash/ 100,000 EEPROM – Data retention: 20 years at 85°C/ 100 years at 25°C(1) – Optional Boot Code Section with Independent Lock Bits In-System Programming by On-chip Boot Program True Read-While-Write Operation – Programming Lock for Software Security • JTAG (IEEE std. 1149.1 Compliant) Interface – Boundary-scan Capabilities According to the JTAG Standard – Extensive On-chip Debug Support – Programming of Flash, EEPROM, Fuses, and Lock Bits through the JTAG Interface • Peripheral Features – Two 8-bit Timer/Counters with Separate Prescalers and Compare Modes – One 16-bit Timer/Counter with Separate Prescaler, Compare Mode, and Capture Mode – Real Time Counter with Separate Oscillator – Six PWM Channels – 8-channel, 10-bit ADC Differential mode with selectable gain at 1x, 10x or 200x – Byte-oriented Two-wire Serial Interface – Two Programmable Serial USART – Master/Slave SPI Serial Interface – Programmable Watchdog Timer with Separate On-chip Oscillator – On-chip Analog Comparator – Interrupt and Wake-up on Pin Change • Special Microcontroller Features – Power-on Reset and Programmable Brown-out Detection – Internal Calibrated RC Oscillator – External and Internal Interrupt Sources – Six Sleep Modes: Idle, ADC Noise Reduction, Power-save, Power-down, Standby and Extended Standby • I/O and Packages – 32 Programmable I/O Lines – 40-pin PDIP, 44-lead TQFP, 44-pad VQFN/QFN/MLF – 44-pad DRQFN – 49-ball VFBGA • Operating Voltages – 1.8 - 5.5V • Speed Grades – 0 - 4 MHz @ 1.8 - 5.5V – 0 - 10 MHz @ 2.7 - 5.5V – 0 - 20 MHz @ 4.5 - 5.5V • Power Consumption at 1 MHz, 1.8V, 25°C – Active: 0.4 mA – Power-down Mode: 0.1µA – Power-save Mode: 0.6µA (Including 32 kHz RTC) |
