ATtiny13A Microcontrollers | DIP-8, SOIC-8 & ISP Kit

ATtiny13A AVR microcontrollers: bare ICs and a separate ISP soldering kit

Choose an ATtiny13A by full device suffix, package, quantity and item type. This collection contains through-hole ATtiny13A-PU DIP-8 chip offers, ATtiny13A-SSU SOIC-8 surface-mount chip offers, multi-model listings with selectable ATtiny13A-SSU variants, and a separate AVR ISP programming-board soldering kit. The chip listings are bare MCUs, not assembled development boards. The kit is board-and-parts hardware requiring assembly and is not a guaranteed included ATtiny13A chip, Uno R3 or finished USB programmer. Some multi-model offers include ATtiny85, ATtiny10, ATtiny24A, ATtiny44A, ATtiny88, ATtiny202, ATtiny414, ATtiny1616 and even a CH32V003 RISC-V MCU as separate choices. A title listing many devices does not mean they ship together or share firmware or pinout.

Pick the package and order quantity

• ATtiny13A-PU, DIP-8: listings include a title stating 10 pcs/lot, a title stating 5 pcs, a single ATtiny13A-PU selected option, and another listing offering 5PCS or 10PCS variants. The through-hole 8-pin format suits a matching DIP socket or PCB footprint. One seller describes the single-chip offer using generic “DIY KIT” and “Voltage Regulator” fields despite its chip title and selected ATtiny13A-PU model; do not assume a board or voltage regulator is included.
• ATtiny13A-SSU, SOIC-8: one dedicated listing names ATTINY13A-SSU with a default variant and describes an SMD SOIC-8 chip. Another SOIC/SOP-8 listing offers 5pcs or 10pcs choices. On three broader multi-model listings, select Color = ATTINY13A-SSU and Model Number = 1pc, 2pcs, 5pcs, 10pcs or 20pcs. Their “Color” option is the MCU model, not a color; “Model Number” is actually quantity. Do not apply the ATtiny85 8 KB title or an all-SOIC-8 package field to other model variants: these multi-model offers also contain devices in SOT-23-6, SOIC-14, TQFP-32, QFN-20 and PDIP-8 formats.
• AVR ISP programming-board soldering kit: a different product lists a bare PCB, DIP sockets (8/14/20/28-pin), headers, LEDs, resistors, capacitors and a 16 MHz crystal for assembly. Its description explicitly says Uno R3 is not included. This is not a factory-assembled ATtiny13A MCU module; check the product's actual contents and the target/programmer connections before ordering it for development.

Technical checks for the ATtiny13A

The detailed ATtiny13A-SSU listing specifies an 8-bit AVR MCU, 1 KB program flash, 64 B SRAM, 64 B EEPROM, a 10-bit ADC and a listed maximum 20 MHz clock rating, with 1.8–5.5 V and -40 to +125 °C stated for that offer. Treat these as part-specific listing information rather than guarantees for all chips, all temperature suffixes or all operating points. Consult the manufacturer's exact datasheet for frequency-versus-voltage conditions, ADC channel/pin sharing, fuse settings, clock calibration, supply and temperature grades. “20 MHz” is not a promise that an unconfigured bare chip starts at 20 MHz, or that a maximum clock is valid at every supply voltage. Verify the precise ordering code and top marking if a specified package, grade or provenance matters.

For hardware, DIP-8 and SOIC-8 are different footprints even when the target device name is similar. Check package drawing, pin-1 orientation, board pad spacing, power and decoupling, reset function and the pins shared by GPIO, ADC and serial programming. A package outline alone cannot prove that ATtiny13A and ATtiny85 are drop-in replacements; program-memory size, peripheral features and firmware target differ. The newer tinyAVR 0/1-series variants and the separate RISC-V choice require their own supported programming interfaces and toolchains. On the small ATtiny13A, memory limits and fuse choices are particularly important: set the compiler/device target correctly, verify available flash/RAM and test the actual clock source and reset configuration before deployment.

For programming, confirm that the programmer and firmware environment explicitly support the selected ATtiny13A and that the board provides the required programming-pin access, target voltage and common ground. The kit listing contains Arduino-as-ISP instructions and mentions a “Burn Bootloader” menu step; that wording does not establish that an ATtiny13A bootloader is included or required. Use the documented programming procedure for the specific MCU and tools, and verify fuse values before altering the reset or clock configuration. An ISP breakout/kit alone does not supply a host Uno R3 or the loose MCU unless expressly included.

Frequently asked questions

Is ATtiny13A-SSU the same physical part as ATtiny13A-PU? Both listings name ATtiny13A-family devices, but SSU is presented as SOIC-8 SMD and PU as DIP-8 through-hole. They do not fit the same PCB footprint; check exact suffix and manufacturer specifications.

Do multi-model listings ship an ATtiny85, ATtiny13A and other devices together? No mixed bundle is established. Select ATTINY13A-SSU as the model and then the intended 1, 2, 5, 10 or 20-piece quantity where those options are offered.

Does the programming-board kit include an Uno R3 or ready-to-use MCU? The listing expressly excludes Uno R3 and describes a kit needing soldering. It does not establish that an ATtiny13A IC or a complete programmer is included.

Can ATtiny85 firmware run unchanged on an ATtiny13A? Do not assume so. The detailed ATtiny13A offer specifies only 1 KB flash; the ATtiny85 title advertises 8 KB for a different selectable device. Compile and test for the chosen MCU and check all pin/peripheral differences.

Are seller claims of “original” or certification independent guarantees? No. Such wording in listing titles and generic descriptions is not independent authentication or verified certification. Confirm documentation and device markings if traceability is required.
