The ATTINY13A-SSUR is an 8-bit high-performance, low-power AVR® RISC architecture microcontroller manufactured by Microchip Technology (formerly Atmel). Packaged in SOIC-8 surface-mount device (SMD) form with the -SSUR suffix indicating standard tape & reel packaging optimized for automated SMT assembly lines, this compact MCU targets cost-sensitive miniature electronic control applications.
Core Architecture & Memory Resources
Built upon the proven AVR RISC core delivering up to 10 MIPS throughput at 10 MHz operating frequency, the device integrates on-chip non-volatile and volatile memory blocks:
1 Kbyte In-System Programmable (ISP) Flash program memory with 10,000 erase/write cycle endurance
64 bytes EEPROM data storage supporting 100,000 erase/write cycles for persistent parameter saving
32 bytes internal SRAM for runtime variable and stack storage
Electrical & Clock Characteristics
Wide supply voltage operation range from 2.7 V to 5.5 V accommodates both lithium battery-powered portable equipment and standard 5V digital systems. A factory-calibrated 8 MHz internal RC oscillator eliminates the requirement for external crystal or resonator components, reducing overall BOM cost and PCB footprint. Multiple configurable power-saving sleep modes (Idle, ADC Noise Reduction, Power-down) drastically cut power draw for battery-operated products extending operational lifespan.
Integrated Peripheral Modules
Despite its tiny 8-pin outline, the ATTINY13A incorporates essential peripheral functions to handle common signal processing and control tasks:
Up to 5 general-purpose digital I/O pins with individual pin change interrupt capability for external event wake-up
4-channel 10-bit successive approximation analog-to-digital converter (ADC) for analog sensor voltage sampling
One 8-bit Timer/Counter with compare match and PWM generation functionality for dimming LED or simple drive control
On-chip analog comparator for fast threshold voltage detection without extra discrete comparators
Packaging & Logistics Specs
Device package: SOIC-8 narrow body surface mount package. The ordering code suffix SSUR stands for tape and reel packaging, compatible with standard pick-and-place manufacturing equipment. The counterpart SSU suffix denotes tube packaging; die, wafer and electrical specifications remain identical between the two variants.
Typical Application Scenarios
This miniature AVR microcontroller is widely adopted across numerous compact electronic solutions including:
Low-cost LED lighting controllers and indicator modules
Portable battery-powered sensor acquisition units
Small home appliance auxiliary control circuits
Simple motor speed/switch control peripherals
Wearable miniature electronic gadgets
Hobby electronics and custom small-scale embedded projects
Reliability Notes
The ATTINY13A series features robust ESD protection and comprehensive in-circuit programming support, enabling firmware updates post PCB assembly via standard ISP programming interfaces.
