ATTINY25V-10SH

Overview

The ATTINY25V-10SH is an 8-bit AVR microcontroller featuring a high-performance RISC architecture with 120 instructions, most executing in a single clock cycle. It integrates 2 KB of In-System Programmable Flash, 128 bytes of EEPROM, and 128 bytes of SRAM. The device supports a maximum clock frequency of 10 MHz at supply voltages between 1.8 V and 5.5 V. It includes six programmable I/O lines, a 4-channel 10-bit ADC, USI, two PWM channels, and an on-chip analog comparator.

Feature Summary

• AVR enhanced RISC core providing throughput approaching 1 MIPS per MHz
• Non-volatile memory with 10,000 Flash write/erase cycles and 100,000 EEPROM cycles
• Universal Serial Interface (USI) supporting SPI and TWI protocols
• On-chip debug system via debugWIRE and ISP programming capability

Applications

• Industrial control systems requiring low power consumption
• Battery-powered embedded applications
• Sensor interface modules utilizing the internal ADC
• General-purpose logic replacement in consumer electronics

Procurement Notes

Verify that the ordering suffix 'H' corresponds to the specific lead finish requirements for your assembly process. Confirm the package type matches the schematic footprint, as this part utilizes an 8-lead SOIC variant. Ensure the voltage grade 'V' aligns with the target operating range of 1.8V to 5.5V. Cross-reference the speed grade '10' against the system clock requirements.

Selection Notes

Select this component when a low-cost 8-bit MCU with functional safety features is required. The 'V' suffix indicates support for operation down to 1.8V, suitable for battery applications. The '10' speed grade offers a balance between processing power and power consumption. Consider the 8-pin package constraints if board space is limited compared to larger packages.

Part Context

This device belongs to the ATtiny25/45/85 family, manufactured using Atmel's high-density non-volatile memory technology. It shares the same core architecture and peripheral set across the series, differentiated primarily by memory size and pin count. The ATTINY25V-10SH specifically targets industrial temperature ranges with a narrow-body SOIC package.

Replacement Considerations

Direct substitutes within the same package and speed grade include ATTINY25V-10SSH. For broader compatibility, other members of the ATtiny25/45/85 family may be considered if memory sizes differ. Verify pinout compatibility, particularly regarding the exchange of PB3 and PB4 pins in ATtiny15 compatibility mode.
