ATMEGA88PA-PU

The ATMEGA88PA-PU is one member of the ATMEGA88PA series.The ATmega88PA 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 ATmega88PA achieves throughputs approaching 1 MIPS per MHz allowing the system designer to optimize power consumption versus processing speed.

Features of the ATMEGA88PA-PU are:(1)131 powerful instructions - most single-clock cycle execution; (2)32 x 8 general purpose working registers; (3)fully static operation; (4)up to 20 MIPS Throughput at 20 MHz; (5)on-chip 2-cycle multiplier; (6)two 8-bit timer/counters with separate prescaler, one compare mode; (7)one 16-bit timer/counter with separate prescaler, compare mode, and capture mode; (8)real time counter with separate oscillator; (9)six PWM channels; (10)power-on reset and programmable brown-out detection; (11)internal calibrated oscillator; (12)external and internal interrupt sources.

The absolute maximum ratings of the ATMEGA88PA-PU can be summarized as:(1)voltage on any pin except RESET with respect to ground:-0.5 to Vcc+0.5V;(2)storage temperature:-65 to 150;(3)operating temperature:-55 to 125;(4)voltage on RESET with respect to ground:-0.5 to 13.0V;(5)DC current per I/O pin:40mA;(6)maximum operating voltage:6.0V;(7)DC current Vcc and GND pins:300mA.The device is manufactured using Atmel's high density non-volatile memory technology. The On-chip ISP Flash allows the program memory to be reprogrammed In-System through an SPI serial interface, by a conventional non-volatile memory programmer, or by an On-chip Boot program running on the AVR core. The Boot program can use any interface to download the application program in the Application Flash memory. Software in the Boot Flash section will continue to run while the Application Flash section is updated, providing true Read-While-Write operation. By combining an 8-bit RISC CPU with In-System Self-Programmable Flash on a monolithic chip, the Atmel ATmega88PA is a powerful microcontroller that provides a highly flexible and cost effective solution to many embedded control applications.
