Atmel 89S/AVR(90S) Socket Stealer
Features
Adds In-System Programmability to existing 8051 and AVR circuits without target system re-design
Removes the problems with implementing and debugging ISP
Complete ISP solution in one. The Socket Stealer incorporates all the necessary ISP hardware, a suitable microcontroller,
suitable reset circuit, ISP programmer connector and crystal
The ISP programmer plugs into the Socket Stealer
All I/O required for programming is isolated from the rest of the circuit when required thus avoiding driver contention
During firmware execution all I/O is available. No I/O is lost to In-System Programming
Can be left in the socket even when a programmer is not connected making field code updates possible
Allows fast code development. Simply apply power and then continuously re-program the microcontroller
Allows easier conversion of an existing 8051 circuit to an AVR design. No need to redesign the reset circuit or change the
crystal
Crystal socket allows changing of crystal frequency with ease
Highly configurable. Six links provided to set various aspects of the Socket Stealer allowing a degree of customisation for
different circuits
Plugs into a 40-pin DIL socket or 44-pin PLCC socket previously occupied by the original microcontroller
Available with a 40-pin to 20-pin adaptor allowing a Socket Stealer to replace an Atmel 89C1051/2051/4051 and provide
In-System Programmability
Low power design. Less than 0.5mA required.
LEDs indicate state of Socket Stealer during programming, erase, etc.
Applications
To migrate an existing non-ISP compatible circuit board to an ISP design.
For code development purposes – simply apply power and then continuously re-program the microcontroller.
To convert an existing 8051 non-ISP compatible circuit board into an AVR (8515/4414) design.
