ATTINY13-20SSJ

Overview

The ATTINY13-20SSJ is an 8-bit AVR microcontroller manufactured by Microchip Technology. It features a high-performance, low-power CMOS architecture with 1K bytes of In-System Programmable Flash, 64 bytes of EEPROM, and 64 bytes of SRAM. The device operates at speeds up to 20 MHz within a voltage range of 2.7V to 5.5V. It includes six programmable I/O lines, a 4-channel 10-bit ADC, an 8-bit Timer/Counter with PWM, and an on-chip analog comparator. The component is housed in an 8-lead SOIC package.

Feature Summary

• Advanced RISC architecture executing most instructions in a single clock cycle for efficient processing.
• In-system self-programmable non-volatile memory segments with high endurance ratings.
• On-chip debug system supporting serial programming via SPI interface.
• Multiple software-selectable power-saving modes including idle, ADC noise reduction, and power-down.

Applications

• Embedded control systems requiring low power consumption
• Battery-operated devices utilizing picoPower technology
• Simple sensor interfaces using the integrated ADC
• Basic automation tasks with timer and PWM capabilities

Procurement Notes

Verify the specific ordering suffix 'SSJ' against official Microchip documentation, as standard listings typically utilize 'SSU'. Confirm current availability status, as this series may be subject to discontinuation notices. Ensure compliance with RoHS standards and verify the industrial temperature range requirements for your specific application environment before finalizing procurement.

Selection Notes

Select this component when a compact 8-pin solution is required for basic control logic. Consider the 20 MHz speed grade if operating voltages are maintained between 4.5V and 5.5V. Evaluate the limited I/O count and memory size against application complexity. Compare against the ATtiny13V variant if operation below 2.7V is necessary.

Part Context

This part belongs to the ATtiny13 family of 8-bit AVR microcontrollers. It shares core architectural features with other variants like the ATtiny13-20PU and ATtiny13A-SSU, differing primarily in package type and specific speed/voltage grades. The family is designed for cost-sensitive applications needing moderate performance with minimal external components.

Replacement Considerations

Direct pin-compatible replacements include ATTINY13-20SSU and ATTINY13A-SSJ if available. Verify electrical specifications and firmware compatibility when substituting. Check for any errata associated with specific silicon revisions that might affect EEPROM writing or debugging functionality.
