ATMEGA168V-10MUR - 8-bit AVR MCU 16KB Flash 10MHz | Microchip
MPN: ATMEGA168V-10MUR ✓ Hoạt độngATMEGA168V-10MUR Tóm tắt
An 8-bit microcontroller integrates a processor core, memory, and peripherals on a single chip, forming the lowest tier of the embedded processor hierarchy (MCU -> embedded processor -> application processor). The AVR family, originally developed by Atmel and now part of Microchip Technology, executes most of its 131 powerful instructions in a single clock cycle, delivering up to 10 MIPS throughput at 10MHz.
Key features include 1.8V to 5.5V operation - the widest voltage range in the ATmega168 family, enabled by the V-grade silicon - plus 23 programmable I/O lines, an 8-channel 10-bit ADC, three flexible timer/counters, and on-chip debugWIRE debugging. Serial interfaces comprise SPI and I2C-compatible TWI, with a full-duplex USART for communications. Self-programming Flash supports in-system programming (ISP) and read-while-write operation.
Architecturally, the AVR uses a Harvard structure with 32 general-purpose working registers directly connected to the ALU, allowing two independent register accesses in a single instruction. Two-cycle multiply and in-system self-programming round out the feature set for cost-sensitive embedded designs.
Typical applications include battery-powered portable devices (exploiting sub-1uA-class power-down modes at 1.8V), industrial sensor nodes, and consumer appliance control boards.
For design, allow programming/debug access to PB5-PB7 and RESET, and place 100nF decoupling on each VCC/AVCC pair.
This page adds value beyond the datasheet with distributor pricing tiers, same-package drop-in alternatives, and practical design notes.

Ứng dụng tiêu biểu
ATMEGA168V-10MUR phù hợp cho 6 Áp dụngs: Battery-Powered Portable Devices, Industrial Sensor Nodes, Consumer Appliance Control, Hobby, Education, and Maker Electronics, Automotive Body and Comfort Subsystems (Non-Safety), IoT Edge Nodes and Wireless Sensor Endpoints.
Battery-Powered Portable Devices
The ATMEGA168V-10MUR's 1.8V minimum supply allows direct operation from a single alkaline or NiMH cell, eliminating boost-converter cost and quiescent drain in handheld meters, remote controls, and wearable accessories. Its AVR power management unit provides idle, power-down, power-save, and standby modes; in power-down the core stops while the asynchronous timer can keep a realtime clock running. Placing the MCU between battery and sensor load with 100nF decoupling on both VCC pins yields clean 10-bit ADC readings. For the longest battery life, the pin-compatible picoPower ATMEGA168PV-10MU further reduces power-down current, but the V-grade already supports year-class standby in low-duty-cycle sampling designs where the MCU wakes a few times per second.

Industrial Sensor Nodes
In factory sensor nodes and transmitters, the ATMEGA168V-10MUR combines an 8-channel 10-bit ADC with a -40C to +85C industrial temperature rating, digitizing up to eight analog channels such as 4-20mA loops, thermistor bridges, or potentiometer feedback. The TWI (I2C) and SPI ports connect external EEPROM, displays, or isolation devices, while the USART streams data over RS-485 via an external transceiver. The 16KB self-programming Flash supports field firmware updates through a bootloader, a key maintenance benefit for hard-to-reach installations. The 32-VQFN exposed pad solders to a ground pour, improving thermal cycling robustness on industrial PCBs exposed to vibration and wide ambient swings.

Consumer Appliance Control
White-goods and small-appliance control boards use the ATMEGA168V-10MUR for keypad scanning, relay/triac control, and LED indication at low BOM cost. Three timer/counters - two 8-bit and one 16-bit - generate hardware PWM for motor speed control, heater phase-angle dimming, or buzzer tones without CPU intervention, keeping interrupt latency predictable. The 23 GPIO lines drive seven-segment or small LCD segments through external drivers, and the internal RC oscillator eliminates the crystal when clock accuracy requirements are modest, freeing PB6/PB7 as extra I/O. The 1.8V to 5.5V range lets one firmware image serve both battery and mains-derived 3.3V or 5V supply architectures across a product family.

Hobby, Education, and Maker Electronics
The ATmega168 core is the MCU inside classic Arduino-class boards, making the ATMEGA168V-10MUR a natural choice for educational kits and maker projects. Extensive open-source tooling - AVR-GCC, avrdude, MPLAB X with XC8, and Arduino bootloaders - plus countless community libraries lower the learning curve to minutes. In-system programming through the 6-pin ISP header (MOSI, MISO, SCK, RESET, VCC, GND) allows reprogramming directly on the target board with an AVR ISP mkII or USBasp. The debugWIRE single-wire interface needs only the RESET line for on-chip debugging, so students can step code without dedicating hardware-breakpoint pins, and the 10-bit ADC reads analog sensors natively.

Automotive Body and Comfort Subsystems (Non-Safety)
For non-safety automotive comfort modules such as seat-position memory, mirror control, or interior LED ambient lighting, the ATMEGA168V-10MUR provides robust peripheral control from a single low-cost MCU, with the A-grade sibling ATMEGA168V-10AUR offering the automotive-temperature option for harsher zones. The MCU's watchdog timer, brown-out detector, and power-on reset deliver dependable reset behavior against automotive supply transients, complementing external load-dump protection. Hardware SPI communicates with LIN or CAN gateways through external transceivers, while the 16-bit timer captures input pulses from hall-effect position sensors. Designs should verify qualification requirements, since this standard part is not itself AEC-Q100 qualified; use the appropriate automotive-grade variant where mandated.

IoT Edge Nodes and Wireless Sensor Endpoints
As the edge controller of sub-GHz RF or Bluetooth modules, the ATMEGA168V-10MUR handles sensor polling, packet formatting, and power sequencing while the radio sleeps. Its USART interfaces directly to wireless modules' AT-command sets, SPI drives low-power RF transceivers, and the 10-bit ADC reads battery voltage and local sensors without an external converter. Duty-cycled firmware wakes the MCU from power-down on watchdog or pin-change interrupts, transmits in tens of milliseconds at 10MHz, and returns to sleep, achieving very low average current for coin-cell nodes. The 32 general-purpose registers and single-cycle ALU handle protocol stacking efficiently, and the exposed-pad VQFN keeps the footprint small on crowded sensor PCBs.

Ghi chú thiết kế
Connect both VCC pins (4 and 6) and AVCC (pin 18) to the same 1.8V-5.5V rail, each with a 100nF ceramic capacitor placed within 2 mm of the pin, plus one 4.7uF-10uF bulk capacitor per board. AVCC must never lag VCC at power-up or the ADC port pins can latch up; a series 10uH inductor plus 100nF to AVCC can be used when ADC noise from the digital rail is a concern. Tie all three GND pins (3, 5, 21) and the exposed pad to the ground plane.
The 32-VQFN exposed pad is the primary thermal and ground path - solder it to a via-stitched ground pour (a 3x3 via array under the pad) rather than leaving it unsoldered, or ground integrity and reflow reliability both suffer. This is an MSL-sensitive MLF package: bake per J-STD-033 if the moisture-barrier bag is exceeded, and use a no-clean flux profile with adequate voiding control under the pad. Pin 1 is identified by the chamfered corner / dot; verify orientation against the datasheet package drawing before stencil cutout.
PC6/RESET (pin 29) doubles as the debugWIRE pin: once the DWEN fuse is set, external reset no longer works until debugWIRE is disabled, which can look like a 'bricked' part on the production line - keep a serial/ISP recovery path. PB6/PB7 default to the crystal function; using them as GPIO requires clearing the CKOUT/low-crystal fuses. When substituting ATMEGA168PB-MU, remember its registers differ - binary images compiled for the original will misbehave. Also confirm brown-out threshold fuses are set appropriately for the chosen supply voltage (1.8V designs need the lowest BOD level).
