Key Parameters

Substitute Part Grouping Explanation

The ATTINY2313V-10PU qualifies as a direct substitute based on the following alignment of critical parameters:

Matching Parameters:

• Core Processor: AVR (same architecture family)
• Core Size: 8-Bit (identical bit width)
• Package / Case: 20-DIP (0.300", 7.62mm) (identical physical form factor)
• Mounting Type: Through Hole (identical mounting method)
• Program Memory Type: FLASH (same memory technology)
• Connectivity: SPI (common interface support)

Enhanced Capabilities: The ATTINY2313V-10PU provides increased program memory (2KB vs. 1KB), higher clock speed (10MHz vs. 4MHz), expanded I/O count (18 vs. 15), and broader supply voltage range (1.8V ~ 5.5V vs. 2.7V ~ 6V). The substitute maintains backward compatibility through identical packaging and AVR core architecture while offering active product status and extended operating temperature range (-40°C ~ 85°C).

Parameter Comparison

Engineering Selection Recommendations

The ATTINY2313V-10PU is suitable for applications requiring AT90S1200-4PC functionality. The substitute part maintains identical package geometry and through-hole mounting compatibility, enabling direct PCB-level replacement without layout modifications. The active product status of the ATTINY2313V-10PU ensures long-term availability and supply chain continuity, addressing the obsolescence of the AT90S1200-4PC.

The substitute's enhanced specifications—including doubled program memory, higher clock frequency, and extended temperature range—provide design margin for existing applications while supporting expanded functionality in new designs. Both devices share AVR core architecture and SPI connectivity, supporting firmware portability with minimal modification.

Frequently Asked Questions (FAQ)

Q: Can the ATTINY2313V-10PU directly replace the AT90S1200-4PC on existing PCBs?

A: Yes. Both devices use identical 20-DIP (0.300", 7.62mm) packaging with through-hole mounting. Pin-to-pin physical compatibility allows direct socket substitution without PCB redesign.

Q: Are there firmware compatibility considerations?

A: Both devices use AVR core architecture and support SPI connectivity. Firmware written for the AT90S1200-4PC requires validation on the ATTINY2313V-10PU due to differences in memory organization, peripheral implementation, and instruction set variations. Refer to device datasheets for instruction-level compatibility details.

Q: What are the supply voltage differences?

A: The AT90S1200-4PC operates at 2.7V ~ 6V, while the ATTINY2313V-10PU operates at 1.8V ~ 5.5V. The substitute supports lower minimum voltage but has a lower maximum voltage. Verify supply voltage compatibility with your application's power distribution design.

Q: Does the ATTINY2313V-10PU offer performance advantages?

A: The substitute provides 10MHz clock speed versus 4MHz, doubled program memory (2KB vs. 1KB), expanded I/O (18 vs. 15), and additional EEPROM (128 x 8 vs. 64 x 8). These enhancements support more complex applications without package or mounting changes.

Q: What is the operating temperature range difference?

A: The AT90S1200-4PC operates at 0°C ~ 70°C, while the ATTINY2313V-10PU operates at -40°C ~ 85°C. The substitute supports extended temperature operation, beneficial for industrial and automotive applications.
