Product details
Overview
ATAVRISP from Microchip Technology (formerly Atmel) is an in-system programmer for AVR Flash microcontrollers, featuring RS-232 PC interface, target-powered operation (2.7–6.0 V), and full support for Flash/EEPROM/fuse/lock-bit programming via AVR Studio or DOS command line. It supports over 30 AVR devices including ATmega32, ATmega128, and ATtiny26.
For engineers reviewing the ATAVRISP datasheet, ATAVRISP pinout, ATAVRISP application, or ATAVRISP equivalent, key selection considerations include its 6-/10-pin ISP connector compatibility, target-voltage range, RS-232 host interface, DOS batch programming capability, and lack of external power requirement.
Technical Context
The ATAVRISP implements serial in-system programming (ISP) using the standard AVR SPI-based protocol, with timing and voltage control managed entirely by AVR Studio or the included DOS utility. It does not contain a microcontroller or firmware update capability - all logic resides in host software.
It interfaces exclusively through a physical RS-232 port and drives the target's RESET, SCK, MISO, MOSI, VCC, and GND lines via a 6-pin or 10-pin ISP header. No onboard voltage regulation or level translation is provided - target supply must meet 2.7–6.0 V specification.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Interface | RS-232 serial connection to host PC - requires DB9 male connector and null-modem cable for modern USB-to-serial adapters. |
| Target Power | Powered directly from target board (2.7–6.0 V) - eliminates need for separate programmer power supply or isolation circuitry. |
| ISP Connector | Supports both 6-pin and 10-pin ISP headers - pinout matches Atmel standard layout; no jumper or mode switch required. |
| Programming Modes | Individual or sequential programming of Flash, EEPROM, fuse bits, and lock bits - controlled via AVR Studio GUI or DOS command-line utility. |
| Supported Devices | 34+ AVR microcontrollers listed in official documentation including ATmega8, ATmega128, ATtiny26, AT90S8515 - no firmware update needed for new device support. |
| Host OS Support | Windows® (via AVR Studio) and MS-DOS - no Linux/macOS native support; DOS utility enables unattended production programming. |
Availability
ATAVRISP is available at Aetrix Electronics and suitable for AVR-based embedded development, field firmware updates, and low-volume production programming requiring stable component supply and legacy toolchain compatibility.
Supply support for ATAVRISP includes scheduled delivery planning, volume procurement assistance, BOM continuity management, traceable sourcing, and lifecycle availability coordination for OEM customers, industrial embedded developers, connected-device designers, and electronics production programs.
Manufacturer
Microchip Technology acquired Atmel in 2016 and maintains legacy product support, documentation, and design resources for AVR tools and microcontrollers.
The ATAVRISP belongs to Atmel's legacy AVR programming hardware family, designed specifically to enable reliable, low-cost in-system programming of Flash-based AVR microcontrollers during development and maintenance.
FAQ
Does the ATAVRISP require an external power supply?
No, the ATAVRISP draws power directly from the target AVR board's VCC line within the 2.7–6.0 V range. This eliminates the need for batteries or wall adapters and simplifies setup in lab or field environments. The ATAVRISP does not regulate or condition input voltage - target supply stability and noise immunity must be verified independently. Always confirm target VCC meets specification before connecting the ATAVRISP.
Which AVR microcontrollers are supported by the ATAVRISP?
The ATAVRISP officially supports 34+ AVR devices including ATmega8, ATmega128, ATtiny26, AT90S8515, ATmega169, and ATmega323, as listed in the original Atmel documentation. Support is implemented entirely in host software (AVR Studio or DOS utility), so no hardware modification or firmware update is required to add new devices - only updated software configuration files are needed.
Can the ATAVRISP be used with modern Windows versions like Windows 10 or 11?
Yes, the ATAVRISP works with Windows 10 and 11 when used with compatible versions of Atmel Studio (v4.18 or earlier) or third-party tools that emulate the legacy AVR Studio ISP protocol. Native driver support may require signed legacy drivers or compatibility mode. The ATAVRISP itself contains no programmable logic - all functionality depends on host-side software implementation and RS-232 signal integrity.
What is the difference between the 6-pin and 10-pin ISP connectors on the ATAVRISP?
The ATAVRISP provides both 6-pin and 10-pin ISP headers wired to the same internal signals per Atmel's standard layout: MOSI, MISO, SCK, RESET, VCC, and GND. The 10-pin header includes additional ground and NC pins for mechanical stability and noise reduction but carries identical functional signals. No configuration or switching is required - either header can be used interchangeably with matching target boards.
Is there a DOS-based programming utility included with the ATAVRISP?
Yes, a DOS command-line programming utility is bundled with the ATAVRISP for batch programming in production environments. It supports automated Flash/EEPROM/fuse programming without GUI overhead and integrates with legacy manufacturing test systems. The utility runs under MS-DOS or DOSBox and communicates via COM port - the ATAVRISP requires no driver installation in pure DOS mode.
