ATTINY861V-10PU

Overview

The ATTINY861V-10PU is an 8-bit AVR microcontroller featuring 8 Kbytes of In-System Programmable Flash, 512 bytes of EEPROM, and 512 bytes of SRAM. It operates within a voltage range of 1.8 V to 5.5 V and supports clock frequencies up to 10 MHz at the higher voltage range. The device includes 16 programmable I/O lines, an 11-channel 10-bit ADC with differential inputs, a Universal Serial Interface (USI), and debugWIRE support. It utilizes a PDIP-20 package for through-hole mounting.

Feature Summary

• Advanced RISC architecture executing most instructions in a single clock cycle
• In-system programmable non-volatile memory with high endurance ratings
• Integrated analog subsystem including 10-bit ADC with programmable gain and on-chip temperature sensor
• Multiple low-power operating modes including Idle, Standby, and Power-Down

Applications

• Battery-powered consumer electronics requiring low active current consumption
• Industrial control systems utilizing the industrial temperature range
• Sensor interface nodes leveraging the high-resolution ADC and analog comparator
• Embedded applications requiring in-system programming via SPI

Procurement Notes

Verify component authenticity against Microchip Technology records due to the mature status of this product line. Confirm that the specific ordering suffix corresponds to the required package type and temperature grade. Ensure design compatibility with the specified voltage and frequency limits before finalizing procurement orders.

Selection Notes

Select this model when 8 Kbytes of program memory and 16 general-purpose I/O lines are required. Choose the 'V' variant specifically for applications necessitating operation down to 1.8 V. Consider alternative packages if surface-mount technology is preferred over the provided through-hole configuration.

Part Context

This component belongs to the ATtinyx61 family of 8-bit AVR microcontrollers manufactured by Microchip Technology. It shares architectural similarities with the ATtiny261 and ATtiny461, differentiated primarily by its memory capacity and pin count. The device represents a mature product line designed for cost-sensitive embedded applications.

Replacement Considerations

Direct substitutes include the ATTINY861-10PU and ATTINY861V-10MU. Verify pinout compatibility and memory specifications when considering these alternatives.
