ATTINY13A-SS7R

Overview

The ATTINY13A-SS7R is an 8-bit AVR microcontroller from Microchip Technology, utilizing the enhanced RISC architecture for high performance and low power consumption. It features 1K bytes of In-System Programmable Flash, 64 bytes EEPROM, and 64 bytes SRAM. The device supports a maximum clock frequency of 20 MHz, operating within a voltage range of 1.8V to 5.5V. Key peripherals include a 4-channel 10-bit ADC, an 8-bit Timer/Counter with PWM, an analog comparator, and a programmable watchdog timer. It is housed in an 8-pin SOIC package.

Feature Summary

• Advanced RISC Architecture: Executes most instructions in a single clock cycle, achieving up to 20 MIPS throughput at 20 MHz.
• Non-volatile Memory Segments: Includes 1KB Flash, 64B EEPROM, and 64B SRAM with high endurance and data retention capabilities.
• Peripheral Integration: Features a 4-channel 10-bit ADC, 8-bit Timer/Counter with two PWM channels, on-chip analog comparator, and debugWIRE system.
• Power Management: Offers multiple low-power sleep modes including Idle, ADC Noise Reduction, and Power-down to optimize energy usage.

Applications

• Battery-powered consumer electronics requiring low standby current
• Ir remote control receivers and simple sensor interfaces
• Basic industrial control logic and monitoring systems
• Smart home automation devices and lighting controls

Procurement Notes

Verify the specific ordering suffix 'SS7R' against official Microchip documentation to confirm package type (SOIC) and tape-and-reel quantity specifications. Ensure compatibility with existing PCB footprints and reflow soldering profiles. Confirm that the speed grade matches the target application's voltage and frequency requirements.

Selection Notes

Select this component for applications needing minimal I/O lines and compact code size. Consider the 8-pin constraint when designing hardware, as only six pins are available for general I/O or peripheral functions. Evaluate power consumption needs against the available sleep modes if battery life is critical.

Part Context

This part belongs to the ATtiny13A family, designed for cost-sensitive and space-constrained embedded applications. It shares architectural similarities with other ATtiny series devices but offers a specific balance of memory and peripheral count suitable for simple control tasks.

Replacement Considerations

Direct pin-to-pin replacements within the same package may include other variants of the ATtiny13A family with different suffixes indicating temperature grades or packaging formats. Verify electrical characteristics and firmware compatibility before substitution.
