ATTINY13-20SUR

Overview

The ATTINY13-20SUR is an 8-bit AVR microcontroller manufactured by Microchip Technology. It features a high-performance, low-power architecture with 1K bytes of in-system programmable Flash memory, 64 bytes of EEPROM, and 64 bytes of internal SRAM. The device supports a maximum clock frequency of 20 MHz at operating voltages between 4.5V and 5.5V. It includes a 4-channel 10-bit ADC, an on-chip analog comparator, and six programmable I/O lines. The component is housed in an 8-lead SOIC package (S8S1) and supplied in tape and reel format.

Feature Summary

• Advanced RISC architecture executing most instructions in a single clock cycle for up to 20 MIPS throughput
• Integrated non-volatile memory segments including self-programmable Flash, EEPROM, and SRAM
• Peripheral set comprising an 8-bit Timer/Counter, 4-channel 10-bit ADC, and on-chip Analog Comparator
• Supports multiple power-saving modes including Idle, ADC Noise Reduction, and Power-down

Applications

• In-system programming via SPI port
• Battery-powered devices utilizing low power consumption modes
• Applications requiring on-chip debug capabilities via debugWIRE

Procurement Notes

Verify the specific speed grade requirements against the datasheet voltage ranges before procurement. The 'SUR' suffix indicates a tape and reel packaging configuration suitable for automated assembly processes. Confirm that the operating voltage aligns with the 2.7V to 5.5V range required for the 20 MHz speed grade. Ensure compliance with RoHS standards as the device is lead-free and halide-free.

Selection Notes

Select this component when a compact 8-bit solution with integrated analog peripherals is required. The ATtiny13 series offers a balance of processing speed and power efficiency suitable for resource-constrained embedded designs. Consider the available I/O lines and memory size relative to application complexity. Verify package availability and ensure the design accommodates the industrial temperature range specifications.
