Key Parameters

Substitute Part Grouping Explanation

Substitution of the ATTINY13A-SSHR is determined by strict equivalence across the following critical parameters:

• Core processor architecture (AVR)
• Core size (8-Bit)
• Operating frequency (20MHz)
• Program memory capacity and type (1KB FLASH)
• EEPROM and RAM specifications (64 x 8 each)
• I/O pin count (6)
• Analog-to-digital converter configuration (4x10b)
• Supply voltage range (1.8V ~ 5.5V)
• Operating temperature range (-40°C ~ 85°C)
• Package type and physical dimensions (8-SOIC)
• Peripheral feature set (Brown-out Detect/Reset, POR, PWM, WDT)

The ATTINY13A-SSUR meets all these criteria and is the manufacturer-recommended substitute, differing only in product status (Active vs. Obsolete) and packaging format designation (Digi-Reel vs. Cut Tape).

Parameter Comparison

Engineering Selection Recommendations

The ATTINY13A-SSUR is the direct equivalent substitute for the ATTINY13A-SSHR. Both devices are manufactured by Microchip Technology and share identical electrical specifications, memory configurations, peripheral features, and package dimensions. The primary distinction is product status: the ATTINY13A-SSHR is classified as Obsolete, while the ATTINY13A-SSUR maintains Active status with significantly higher inventory availability (20,100 units vs. 1,736 units).

Both parts maintain ROHS3 compliance and REACH Unaffected status, satisfying regulatory requirements for new designs and production. The ATTINY13A-SSUR is the manufacturer-recommended alternative and is suitable for direct replacement in all applications where the ATTINY13A-SSHR was previously specified.

Frequently Asked Questions (FAQ)

Q: Can the ATTINY13A-SSUR be used as a direct replacement for the ATTINY13A-SSHR?

A: Yes. The ATTINY13A-SSUR is electrically and mechanically identical to the ATTINY13A-SSHR. All functional parameters, memory specifications, peripheral features, supply voltage ranges, operating temperature ranges, and package dimensions are equivalent. The devices are pin-compatible and require no circuit modifications.

Q: What is the difference between ATTINY13A-SSHR and ATTINY13A-SSUR?

A: The devices differ only in product status and packaging format designation. The ATTINY13A-SSHR is Obsolete, while the ATTINY13A-SSUR is Active. Both are supplied in 8-SOIC packages; the designation difference reflects supply chain format (Cut Tape vs. Digi-Reel).

Q: Are there any compatibility concerns when switching from ATTINY13A-SSHR to ATTINY13A-SSUR?

A: No compatibility concerns exist. The devices share identical pinouts, electrical characteristics, and functional specifications. Existing PCB layouts, firmware, and application code require no modification.

Q: What is the package type for both devices?

A: Both the ATTINY13A-SSHR and ATTINY13A-SSUR are supplied in 8-SOIC (Small Outline Integrated Circuit) packages with a width of 0.154 inches (3.90mm). This is a standard surface-mount package compatible with automated assembly processes.

Q: Do both parts meet current regulatory standards?

A: Yes. Both the ATTINY13A-SSHR and ATTINY13A-SSUR are ROHS3 compliant and REACH Unaffected, meeting current environmental and regulatory requirements for electronic components.
