Substitute Part Grouping Explanation

Substitution of the AT90S2313-10PI is determined by equivalence across the following critical parameters:

• Core Architecture: AVR processor family ensures instruction set compatibility
• Memory Configuration: Identical 2KB FLASH, 128-byte EEPROM, and 128-byte RAM
• Operating Speed: 10MHz clock frequency
• Package Form Factor: 20-DIP through-hole mounting
• Connectivity Interfaces: SPI and UART/USART support
• Peripheral Feature Set: Brown-out detection, Power-on Reset, PWM, and Watchdog Timer

The ATTINY2313V-10PU qualifies as a direct substitute based on matching core memory specifications, clock speed, package type, and peripheral functionality. Variations in supply voltage range and I/O count do not preclude substitution when system design accommodates these differences.

Parameter Comparison

Engineering Selection Recommendations

The ATTINY2313V-10PU serves as the primary substitute for the obsolete AT90S2313-10PI. Both devices share identical core memory architecture, clock frequency, package form factor, and peripheral feature sets. The substitute maintains active product status with Atmel, ensuring continued availability and manufacturing support.

The ATTINY2313V-10PU offers an expanded supply voltage range (1.8V ~ 5.5V) compared to the original part (4V ~ 6V), providing greater flexibility in power supply design. The substitute also provides three additional I/O pins (18 versus 15), which may be utilized in new designs without affecting backward compatibility for existing applications.

Both devices are classified under ECCN EAR99 and HTSUS 8542.31.0001, maintaining equivalent export and tariff compliance profiles.

Frequently Asked Questions (FAQ)

Q: Can the ATTINY2313V-10PU directly replace the AT90S2313-10PI in existing designs?

A: Yes. Both devices share identical program memory (2KB FLASH), data memory (128-byte EEPROM and RAM), clock speed (10MHz), package type (20-DIP), and peripheral feature sets. Existing firmware compiled for the AT90S2313-10PI will execute on the ATTINY2313V-10PU without modification.

Q: What are the differences between these two parts?

A: The primary differences are product status (obsolete versus active), supply voltage range (4V–6V versus 1.8V–5.5V), and I/O pin count (15 versus 18). The substitute's wider voltage range and additional I/O pins do not create incompatibility with designs originally specified for the AT90S2313-10PI.

Q: Are there any package or pinout differences?

A: No. Both devices use the 20-DIP (0.300", 7.62mm) through-hole package with identical pinout and mechanical dimensions, enabling direct socket substitution.

Q: Why is the AT90S2313-10PI classified as obsolete?

A: The AT90S2313-10PI is part of the legacy AVR 90S series. Atmel transitioned this product line to the ATtiny series, with the ATTINY2313V-10PU representing the active continuation of this microcontroller family.

Q: Does the expanded voltage range of the ATTINY2313V-10PU affect compatibility?

A: No. The substitute's 1.8V–5.5V range encompasses the original part's 4V–6V specification. Designs operating within the original voltage range will function identically on the substitute.
