89S/AVR(90S) Socket Stealer
Document Version 1.0
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.
Compatible ISP Programmers
