ATMEGA88PA-CCUR 개요
An 8-bit microcontroller (MCU) is a single integrated circuit that contains a processor core, memory, and programmable peripherals, forming the lowest tier of the embedded processor hierarchy (MCU -> embedded processor -> system-on-chip -> application processor). The AVR ATmega family from Microchip uses an advanced RISC architecture with 130 powerful instructions, most executing in a single clock cycle, achieving up to 20 MIPS throughput at 20 MHz.
Key features include the picoPower technology of the PA suffix, which reduces power consumption in active and sleep modes; 1 KB of internal SRAM; 512 bytes of EEPROM for non-volatile data storage; and a two-wire serial interface (I2C-compatible), SPI, and USART for connectivity. The device supports In-System Programming (ISP) and in-circuit debugging via the debugWIRE interface using tools such as the MPLAB SNAP.
Architecturally, the ATmega88PA combines a Harvard-structure 8-bit RISC core with separate program and data buses, hardware multiplier, and three flexible timer/counters with compare modes. An 8-channel 10-bit ADC provides analog acquisition capability, while internal calibrated RC oscillator options reduce external component count.
Typical applications include portable and battery-powered consumer devices, industrial sensor nodes, HVAC and lighting control, and compact space-constrained designs where the 4x4 mm UFBGA ball-grid package provides significant board-area savings over TQFP/QFN alternatives.
Design consideration: the UFBGA package requires precise PCB footprint design and reflow soldering; ball pitch and land pattern per the manufacturer datasheet must be followed, and X-ray or acoustic inspection is recommended for BGA solder-joint verification.
This page synthesizes distributor pricing, drop-in same-package alternatives, and practical UFBGA design guidance not consolidated in the manufacturer datasheet.

일반적인 애플리케이션
ATMEGA88PA-CCUR 적합 용도: 6 애플리케이션s: Battery-Powered Portable Devices, Industrial Sensor Nodes, Lighting and HVAC Control, Consumer Appliances and IoT Endpoints, Space-Constrained Embedded Designs, Legacy ATmega8/88 Design Migration.
Battery-Powered Portable Devices
The ATMEGA88PA-CCUR fits battery-powered products because its PA-grade picoPower technology minimizes sleep and active current, and its 1.8 V minimum supply allows direct operation from two alkaline cells or a single-cell lithium rail through an LDO. In a typical sensor-tag design the MCU spends most time in power-down sleep, waking on pin-change or watchdog timeout to sample a sensor via the 10-bit ADC and transmit over USART or SPI. The 32-UFBGA (4x4 mm) package keeps total PCB area under 2 cm2, enabling compact wearable and handheld form factors that a 7x7 mm TQFP could not meet.
추천
Industrial Sensor Nodes
In industrial monitoring nodes, the ATMEGA88PA-CCUR combines a 20 MHz RISC core, 10-bit ADC, and I2C/SPI/USART connectivity to aggregate analog and digital sensor data over RS-485-attached UART links or short-range radios. The -40C to +85C industrial temperature rating and brown-out detection with internal 2.56 V reference support reliable operation on noisy factory floors with unregulated 5 V rails. The 8 KB FLASH holds protocol stacks and local filtering logic while 1 KB SRAM buffers sample bursts; the 4x4 mm UFBGA lets the node electronics fit inside M12 sensor connectors and other space-limited housings.
추천
Lighting and HVAC Control
The ATMEGA88PA-CCUR drives lighting ballasts, dimmers, and HVAC damper controls using its three timers with PWM outputs and 23 GPIO for relay and triac interfacing. The 10-bit ADC reads temperature sensors (NTC), potentiometers, and current-shunt feedback, while the hardware PWM generates phase-cut or DC dimming waveforms without CPU overhead. Its 1.8 V to 5.5 V supply range accepts wide-tolerance wall-adapter rails, and brown-out reset prevents corrupt EEPROM parameter storage during mains brownouts. The compact UFBGA package suits slim wall-plate and ceiling-module form factors typical of commercial lighting fixtures.
추천
Consumer Appliances and IoT Endpoints
Consumer appliance control panels, small appliances, and Wi-Fi/Bluetooth module-connected IoT endpoints use the ATMEGA88PA-CCUR as the low-cost main controller: it reads capacitive or mechanical buttons, drives LED indicators and seven-segment or LCD drivers over SPI, and exchanges status frames with a connectivity module through USART. The 20 MIPS throughput handles debounce, state machines, and checksum-protected communication simultaneously, while picoPower sleep modes keep standby draw low enough for always-plugged products targeting energy-efficiency limits. Tape-and-reel supply (the R suffix) supports high-volume automated SMT assembly lines typical of consumer manufacturing.
추천
Space-Constrained Embedded Designs
Any design where board area dominates - RFID readers, small medical dongles, dongle-form instrumentation, and multi-chip dense assemblies - benefits from the ATMEGA88PA-CCUR's 4x4 mm, 32-ball UFBGA package, which reduces controller footprint by roughly 35% versus a 7x7 mm QFN and far more versus TQFP. The BGA's short ball interconnects also improve signal integrity on the SPI and clock lines at 20 MHz. Designers should budget for reflow-only assembly, X-ray first-article inspection, and exposed test pads for debugWIRE programming, since the package cannot be socketed or hand-soldered.
추천
Legacy ATmega8/88 Design Migration
Designs migrating from ATmega8 or original ATmega88 devices can adopt the ATMEGA88PA-CCUR for its picoPower efficiency and active lifecycle status. Per Microchip application note AVR094, the ATmega88 is pin compatible with the ATmega8 with a very similar feature set, and the PA variant further reduces power while keeping the same 8 KB/1 KB/512 B memory map, peripheral register model, and ISP/debugWIRE tooling. Because the CCUR is only available in UFBGA, migration to this exact MPN suits new board spins; existing TQFP/QFN boards should instead migrate to ATMEGA88PA-AUR or -ANR in their native footprints.

주요 차별점
- picoPower low-power die in the smallest footprint (vs ATMEGA88PA-AUR)
- Lower minimum supply voltage than non-PA variant (vs ATMEGA88A-CCU)
- Memory upgradability without PCB change (vs ATMEGA168PA-CCU)
설계 노트
The 32-UFBGA (4x4 mm) package requires reflow soldering with a land pattern exactly per the Microchip datasheet footprint drawing. Use non-solder-mask-defined pads matched to the ball diameter, and fan out the 0.65 mm-class ball grid with via-in-pad or dog-bone escape routing on at least a 4-layer board for power integrity. Because BGA joints cannot be visually inspected, plan X-ray or acoustic microscopy inspection for first-article and periodic process qualification, and never rework the package more than the datasheet reflow cycle limit allows.
Decouple the VCC/AVCC ball pairs with 100 nF ceramic capacitors placed within 2 mm of the corresponding balls, plus one bulk 4.7-10 uF capacitor per rail. If the 10-bit ADC is used, connect AVCC to VCC through an LC filter (ferrite bead + capacitor) to reject digital switching noise, and keep the analog ball traces away from the 20 MHz clock and USART lines. When running below 3 V, note that maximum guaranteed clock frequency is derated below 20 MHz per the frequency-versus-voltage curve in the family datasheet.
The R suffix means tape-and-reel - do not substitute the tray-packaged ATMEGA88PA-CCU on automated lines without confirming feeder compatibility. Ensure every I/O ball used for programming (MOSI, MISO, SCK, RESET) has test-pad access, since the BGA cannot be socketed for bench programming. Also verify firmware register compatibility before migrating from ATMEGA88A to ATMEGA88PA: while functionally equivalent, the picoPower die has updated sleep-mode control bits, and code written for the A version should be re-validated against the PA datasheet.
규정 준수 정보
