The ATMEGA88PA‑AUR is an 8‑bit low‑power AVR RISC microcontroller from Microchip, packaged in 32‑TQFP tape‑and‑reel form, operating up to 20 MHz clock speed, equipped with 8KB in‑system programmable flash memory, 512B EEPROM and 1KB SRAM, featuring 10‑bit ADC, SPI, I2C, USART and multiple timer/PWM peripherals, supporting single supply from 1.8V to 5.5V within ‑40°C to +85°C industrial temperature range for compact battery‑powered embedded control applications.
Key Feature AND Application
● High‑performance AVR RISC architecture with 131 assembly instructions, most instructions complete within one clock cycle to reach 20 MIPS at 20 MHz.
● PicoPower low‑power technology with multiple sleep modes to cut standby consumption for battery‑operated electronic products.
● Rich integrated peripherals including 8‑channel 10‑bit ADC, dual 8‑bit timers, one 16‑bit timer, SPI, TWI(I2C) and USART for serial communication.
● 23 general‑purpose I/O pins, power‑on reset, brown‑out detector and watchdog timer to enhance system stability under fluctuating supply conditions.
● In‑system programming (ISP) capability for on‑board firmware update, compact TQFP‑32 package and RoHS compliance for small PCB designs.
This AVR MCU is widely used for smart sensor nodes, simple home automation modules, handheld portable gadgets, LED lighting controllers, consumer electronic control boards, low‑speed data loggers and general embedded projects that require low power consumption, small footprint and cost‑effective 8‑bit control capability.
FAQ
Q: What are key design considerations for ATMEGA88PA‑AUR?
A: Select proper BOD level according to supply voltage, set fuse bits carefully to avoid locking the chip, add decoupling capacitors near VCC pins, and match maximum clock frequency with operating voltage.
Alternative embedded control IC Models
1. ATMEGA88A‑AUR: Pin‑compatible TQFP‑32 AVR MCU without PicoPower low‑power enhancement, for cost‑focused projects with less strict standby current requirements.
2. ATMEGA168PA‑AUR: Footprint‑identical 32‑pin MCU with upgraded 16KB flash memory, for designs requiring larger program storage capacity.
3. ATMEGA48PA‑AUR: TQFP‑32 AVR microcontroller with reduced 4KB flash, serving as a downgrade option for simple firmware with small code size.
