Overview
The ATTINY45V-10SI is an 8-bit AVR microcontroller manufactured by Microchip Technology, featuring 4KB of In-System Programmable Flash memory. It operates at a maximum clock frequency of 10 MHz with a supply voltage range of 1.8V to 5.5V. The device includes 256 bytes of EEPROM and 256 bytes of SRAM. It utilizes an 8-lead Plastic Gull-Wing Small Outline (EIAJ SOIC) package.
Feature Summary
- Advanced RISC architecture executing most instructions in a single clock cycle
- Non-volatile program and data memories with high endurance ratings
- Integrated peripheral features including timers, ADC, and serial interfaces
- Support for multiple low-power operating modes
Applications
- Industrial temperature range embedded control systems
- In-system programming via SPI port applications
- Low power consumer electronics requiring extended battery life
Procurement Notes
Verify the specific ordering code matches the required speed grade and voltage range. Confirm the package type corresponds to the design footprint. Ensure compliance with RoHS directives if applicable. Check for any errata related to PLL locking or power consumption in early revisions.
Selection Notes
Select this component when a balance of processing speed and low power consumption is required. The V suffix indicates operation down to 1.8V, suitable for battery-powered designs. Consider the 10MHz speed grade for applications needing moderate throughput without exceeding the lower voltage limits.
Part Context
This part belongs to the ATtiny25/45/85 family of 8-bit microcontrollers based on the AVR enhanced RISC architecture. The family offers varying flash sizes while sharing common peripheral sets and pinouts. The 'V' variant extends the operational voltage range to include 1.8V, broadening its utility in portable devices.
