ATTINY13A-SSH

Overview

The ATTINY13A-SSH is an 8-bit AVR microcontroller featuring a 20 MHz maximum clock frequency and 6 programmable I/O lines. It integrates 1 KB of In-System Programmable Flash, 64 bytes of EEPROM, and 64 bytes of SRAM. The device operates within a voltage range of 1.8 V to 5.5 V and supports industrial temperature ranges. Key peripherals include a 4-channel 10-bit ADC, an 8-bit Timer/Counter with PWM, and an on-chip analog comparator.

Feature Summary

• Advanced RISC architecture enabling single-clock-cycle instruction execution for optimized power-to-performance ratios.
• Integrated debugWIRE on-chip debugging system allowing efficient development without external hardware probes.
• Multiple software-selectable low-power sleep modes including Idle, ADC Noise Reduction, and Power-down.
• High endurance non-volatile memory segments supporting extensive write and erase cycles.

Applications

• Battery-powered consumer electronics requiring extended operational life.
• Simple sensor interface nodes utilizing the integrated ADC capabilities.
• Basic motor control applications leveraging the timer and PWM outputs.
• Low-cost embedded systems needing in-system programming via SPI.

Procurement Notes

Verify the specific suffix 'SSH' against Microchip's official ordering guide to confirm package type and temperature grade. Ensure compatibility with existing PCB footprints for the SOIJ/SOIC variant. Confirm that the required firmware does not exceed the 1 KB Flash capacity. Check for any end-of-life notices or alternative recommendations from the manufacturer before finalizing procurement plans.

Selection Notes

Select this component when design constraints demand minimal pin count and low active current consumption. It is suitable for applications where code size fits within 1 KB and limited I/O resources are acceptable. Consider the operating voltage range to ensure compatibility with the target power supply. Evaluate the need for analog features like the ADC if signal conditioning is required in the application.

Part Context

This part belongs to the ATtiny13A family, which utilizes Microchip's picoPower technology. It shares architectural similarities with other 8-pin AVR devices but offers specific memory and peripheral configurations tailored for cost-sensitive, space-constrained designs. The series emphasizes high performance per milliwatt through its efficient RISC core.

Replacement Considerations

Direct substitutes may include ATTINY13A-SSU or ATTINY13A-SH depending on package availability. Verify pinout compatibility and electrical specifications before substitution. Cross-reference fuse settings and calibration data if migrating between different revision levels of the same family.
