89S/AVR(90S) Socket Stealer
Document Version 1.0
Atmel 89S/AVR(90S) Socket Stealer
1. Introduction
1.1 Overview
With the pressing timescales of modern-day electronic design, developers are often faced with the task of designing unproven
circuitry onto a circuit board, only to find out that the design doesn’t work as expected when the PCB arrives back from
manufacture. Implementing in-system programming (ISP) of Atmel microcontrollers for the first time on a circuit board is
fraught with pitfalls as there are considerations such as choice of ISP header, power supply constraints, SPI contention
problems, Reset timing problems etc. Debugging of such problems can be very time consuming as it is not possible to isolate
just one cause.
In light of all the potential problems with implementing ISP, Equinox have come up with a range of ‘ISP Socket Stealer
Modules’ which convert an existing non-ISP compatible target board into a working ISP solution by simply plugging the
module into the microcontroller socket on the target board. The ‘Socket Stealer’ incorporates all the necessary ISP hardware
including ISP microcontroller, Reset circuit, ISP programmer connector and crystal. An ISP programmer such as the Equinox
‘Micro-ISP’ or ‘Activ8r’ connects to the ISP connector on the module and allows serial downloading/uploading of data from
the module. The advanced electronic circuitry on-board the ‘Socket Stealer’ isolates all relevant programming lines during the
ISP process ensuring that even with SPI bus contention, the microcontroller will still be able to be successfully programmed. It
is also possible to leave the ‘Socket Stealer’ in the target socket even when a programmer is not connected making field code
updates possible.
The diagram below shows how the microcontroller plugs into the Socket Stealer which in turn plugs into a target board. A
version of the Socket Stealer is also available that will allow it to plug into a PLCC-44 socket on the target board.

89S/AVR(90S) Socket Stealer
1.3.3 Block 1 – Equinox ISP Programmer
This block represents an Equinox programmer featuring ISP. The diagram shows the key signals that the programmer provides
to allow the Socket Stealer to function correctly. /RESET controls the reset of the microcontroller (block 3), /SS, MOSI, MISO
and SCK are all used for programming of the microcontroller and PROG is used to control connection of the ISP signals to the
target circuit (block 5). When PROG is active the switches are open. When an operation such as programming, erasing, etc. is
not taking place all the signals from the programmer are high impedance.
1.3.4 Block 2 – Reset Circuit
This block represents the reset circuit which is based on a RC network with some logic. The purpose of the circuit is to
combine both the reset from the target board (block 5) and the reset from the programmer (block 1) into one signal for the
microcontroller (block 3). This allows the microcontroller to be reset by both the programmer (during ISP) and the target board
(for example on power up).
1.3.5 Block 3 – ISP Enabled Microcontroller
This block represents the microcontroller that is plugged into the Socket Stealer. It must be an Atmel AT89S device such as the
AT89S8252 or an Atmel AT90S4414/8515. Most of the I/O is connected straight to the target circuit (block 5). The ISP signals
(/SS, MOSI, MISO and SCK) connect directly to the programmer (block 1) and through analogue switches (block 4) to the
target circuit (block 5).
1.3.6 Block 4 – Analogue Switches
These switches allow the programmer (block 1) to control when the ISP pins of the microcontroller (/SS, MOSI, MISO and
SCK) are connected to the target circuit or not. During programming the PROG signal is active and the switches are open
thereby disconnecting the ISP pins from the target circuit (block 5). This avoids any driver contention problems. When
programming is not taking place or the programmer is disconnected the switches are closed thereby allowing the pins to be
used for normal I/O.
1.3.7 Block 5 – Target Circuit Microcontroller Socket
This block represents the socket on the target board where the microcontroller normally plugs in. When the Socket Stealer is
being used it plugs into this socket instead. When an operation such as programming, erasing, etc. is not taking place the
microcontroller on the Socket Stealer is effectively plugged into this socket.
1.4 Advantages of the Design
·
·
·
·
·
·
Problems associated with designing In-System Programmable circuits have been removed
Allows hardware on the SPI bus (/SS, MOSI, MISO and SCK) to be used with interfering with programming
Adds In-System Programmability to existing designs that do not have this feature
Target circuit redesign is not required
Makes field upgradable firmware possible and easy to perform
Enables designs to convert from an 8051 microcontroller to an AVR microcontroller more easily. Allows the crystal to be
easily changed and the existing 8051 reset circuit can be used
1.5 Design Notes
The use of analogue switches results in a series resistance being introduced on four of the microcontroller I/O lines. This could
cause I/O port loading problems with some existing boards. Please refer to section 4 for further information on the analogue
switch resistance.

89S/AVR(90S) Socket Stealer
2.3.1 Links B1 and B2 – Microcontroller and Target Circuit Selection
The Socket Stealer may plug into a target circuit that has been designed for an Atmel 90S4414/8535 AVR microcontroller or a
generic 8051 microcontroller (please refer to the Device Support section). In addition it may accept an AVR 90S4414/8515 or
8051 89S device.
The AVR family has an active low RESET and the 8051 family has an active high RESET resulting in reset circuits for the two
families being different. In order to enable the Socket Stealer to plug into a target circuit that may have an incompatible reset
circuit for the microcontroller two links are provided, B1 and B2.
Link B1 selects the type of reset circuit on the target system. Connecting pads 1 and 2 together configures the Socket Stealer to
plug into an AVR system and connecting pads 2 and 3 together configures the Socket Stealer to plug into an 8051 system.
Link B2 selects the family of microcontroller plugged into the Socket Stealer itself. Connecting pads 1 and 2 together
configures the Socket Stealer for an AVR 90S device and connecting pads 2 and 3 together configures the Socket Stealer for an
89S device.
The way the reset circuit works on the Socket Stealer is to convert the target system RESET to active low if link B1 has 2 – 3
connected. This active low RESET signal is then ANDed with the RESET signal from the programmer, which is configured to
always be active low. Then if link B2 has 2 – 3 connected the microcontroller is an 8051 device and the RESET signal requires
inverting, producing an active high RESET. A simplified circuit diagram is shown below.
Section 3.1 details how to configure the programmer so that the RESET signal produced is always active low.

89S/AVR(90S) Socket Stealer
2.3.2 Links B3 and B4 – Crystal Selection
It is possible to choose between using a crystal on the target system or a crystal plugged into the Socket Stealer using links B3
and B4. This option allows designs for one microcontroller family (8051 or AVR) to migrate more easily to the other
microcontroller family, as both families have different requirements for the crystal frequency. The crystal already on the target
system does not need to be removed to use a crystal on the Socket Stealer.
Connecting pads 1 and 2 together on both links B3 and B4 select the crystal on the target system. Connecting pads 2 and 3
together on both links B3 and B4 select the crystal on the Socket Stealer.
A simplified circuit diagram is shown below.
2.3.3 Link B5 - /EA and ICP Configuration
For 8051 devices the /EA pin selects between execution from internal or external memory. Link B5 allows this pin to be either
connected to /EA on the target circuit or directly to the supply voltage Vcc on the Socket Stealer (selecting execution from
internal memory).
Connecting pads 1 and 2 together on link B5 connects the /EA pin to the target system /EA. Connecting pads 2 and 3 together
on link B5 connects the /EA pin to Vcc.
When using the 40-pin to 20-pin 8051 adaptor the /EA pin must be tied to Vcc for correct operation. This is due to the 20-pin
8051 devices not featuring /EA so when the adaptor is connected and /EA is not tied to Vcc by setting link B5 to 2 – 3, the /EA
is left unconnected giving unreliable behaviour.
On AVR devices the ICP pin controls the timer/counter 1 Input Capture function. Link B5 allows this pin to be either
connected to the target circuit ICP or tied directly to Vcc on the Socket Stealer. If the input is being used then the pin should be
connected to the target circuit otherwise it should be held at a constant logic level, either on the target circuit or by connecting
the input directly to Vcc on the Socket Stealer.
Connecting pads 1 and 2 together on link B5 connects the ICP pin to the target system ICP. Connecting pads 2 and 3 together
on link B5 connects the ICP pin to Vcc.

89S/AVR(90S) Socket Stealer
A simplified circuit diagram is show below.
2.3.4 Link B6 - /PSEN and OC1B Configuration
On 8051 devices /PSEN is the external memory read strobe and link B6 allows this pin to either remain unconnected or
connect to /PSEN on the target system. If pads 1 and 2 are connected together on link B6 then the pin is connected to the target
system. This is only required if external program memory is being used.
On AVR devices OC1B is the output pin for the timer/counter 1 Output CompareB function. This pin may either be left
unconnected or connected to OC1B on the target system. If pads 1 and 2 of link B6 are connected then the pin is connected to
the target system. This is only required if the timer/counter 1 Output CompareB function is required.
A simplified circuit diagram is shown below.

2.4 Socket Stealer Links Diagram
This is the view of the underside of the Socket Stealer looking at the DIL pins. Each link (B1 to B6) is made up of two or three
square pads which are numbered as shown in the diagram.
2.5 40-pin to 20-pin 8051 Adaptor
The Socket Stealer can plug into a 40-pin DIL to 20-pin DIL adaptor which allows it to be used in place of an Atmel 20-pin
8051 device (AT89C1051/2051/4051). The 20-pin devices however do not feature an /EA pin, so if link B5 has pads 1 and 2
connected then the /EA pin of the microcontroller is left unconnected. This can cause unreliable operation for example
“Programmer not detected” errors, incorrect programming, reading, verification and erasing may result. When using the
adaptor link B5 should be set to 2 – 3 to connect /EA to Vcc.

89S/AVR(90S) Socket Stealer
3. Using the Socket Stealer
3.1 Configuring Meridian
8051 devices have an Active High RESET and AVR devices have an Active Low RESET. By setting the links on the socket
stealer it can be configured to accept an AVR or 8051 device and plug into a target system with a RESET circuit designed for
an AVR or 8051 device. In order for the Socket Stealer to work correctly the ISP programmer (Micro-ISP or Activ8r) must
itself be configured to produce an Active Low RESET regardless of the device family that is being used. An Active Low
RESET is selected automatically in Meridian when an AVR device is chosen, however every time an 89S device is chosen the
RESET is set to Active High.
The PROG signal from the programmer can also be configured for Active High or Active Low operation. Normally this signal
is Active Low but when using the Socket Stealer it has to be configured as Active High.
The following steps describe how to change the RESET to Active Low and to set PROG to Active High:
1. From the Options menu choose “ISP Settings…”
2. Click on “Active low” in the Reset box.
3. Click on “Active High” in the PROG/Shutdown box.
4. Click on the “OK” button.
The screenshot below shows the ISP Interface Settings dialogue box for an AT89S8252 with the Reset and PROG set
accordingly for an 89S Socket Stealer.

89S/AVR(90S) Socket Stealer
3.2 LEDs
There are two LEDs on the Socket Stealer. The green LED indicates that that the programmer is active and an operation such
as read, verify, erase or program is being performed. The red LED indicates that the RESET of the microcontroller is active.
3.3 89S Device Locking
It is possible to lock 89S devices so they cannot be In-System programmed again due to a bug in the silicon. This can be
avoided by ensuring that your firmware does not write to the SCK pin of the 89S device within the first 700ms of execution,
possibly by including a large initial loop.
4. Technical Information
This section describes various aspects of the Socket Stealer that you should bear in mind when designing a target system or
when using the Socket Stealer with an existing design.
4.1 Current Consumption
The Socket Stealer draws approximately 0.5mA of current from the target circuit when the supply voltage Vcc is +5V.
4.2 Analogue Switch Resistance
Each analogue switch has a resistance when closed of 470W. This can have an effect on any hardware connected to pins
P1.4/PB4, P1.5/PB5, P1.6/PB6 and P1.7/PB7 on the target circuit due to the voltage drop across the switch.
5. Device support
Please note that although supported devices may have a range of possible supply voltages, the Socket Stealer has been
designed to operate only with a supply voltage of +5V.
5.1 Devices Inserted into the Socket Stealer
The Socket Stealer will accept the following Atmel 8051 devices providing the links are set correctly:
· AT89S8252
· AT89S53
· AT89LS8252 (+5V Vcc only)
· AT89LS53 (+5V Vcc only)
The Socket Stealer will accept the following Atmel AVR devices providing the links are set correctly:
· AT90S4414 · AT90S8515
