2 Sockets
The EEPROM Socket Board - 10/34 offers three different sockets to interface with your memory chip: DIP8, SOIC8 and TSSOP8. Please note that only one can be used at a time as they are all cross-connected.
2.1 Compatible Chip Sizes
The three sockets of the EEPROM Socket Board are compatible with standard sized chip packages. Figure 7 provides information about the supported sizes for all the sockets. Please note that all measurements are in millimeters (mm).
Compatible chip sizes for each of the sockets available on the EEPROM Socket Board. All measurements are in millimeters (mm).
| DIP8 | SOIC8 | TSSOP8 | ||
| Pitch | (P) | 2.54 | 1.27 | 0.65 |
| Thickness | (A) | 3.94 | 1.90 | 1.00 |
| Lead Tip-to-Tip Width | (E) | 7.94 | 6.00 | 6.40 |
| Molded Package Width | (E1) | 6.35 | 3.90 | 4.40 |
| Overall Length | (D) | 9.46 | 5.40 | 3.00 |
3 Connectors
3.1 34-pin Boxed Connector and 10-pin Boxed Connectors
The sockets are connected to 34-pin boxed connector and to 10-pin boxed connectors which are located directly beneath it. The 34-pin boxed connector (Promira) is used to connect the sockets to Promira Serial Platform to program the target device. The 10-pin boxed connectors (Aardvark 1 and Aardvark 2) are used to connect the sockets to Cheetah SPI Host Adapter or Aardvark I2C/SPI Host Adapter to program the target device. The two 10-pin boxed connectors are cross-connected, so it does not matter which one is used. In most cases, you will only want to connect a single adapter to the EEPROM Socket Board at a time.
The second 10-pin boxed connector is available to connect to a protocol analyzer or to cross connect with another adapter for testing purposes. For example, an Aardvark adapter or a Cheetah adapter can be connected to the board through Aardvark 1 connector to program the memory chip. At the same time, a Beagle I2C/SPI Protocol Analyzer can be attached to Aardvark 2 connector to monitor the bus while the chip is being programmed to ensure that the data on the bus is correct.
3.2 External Connector
Some of the signals on the board are available for external monitoring through the External connector (J1). The two VExt pins allow a user to use an external power source to power the memory device. Please refer to the Programming a Device section for more information.
3.3 VDD Source Connector
The VDD source connector (JP1) has 4 jumpers options, which configured the power source to the memory: 3.3V, VTgt, VLvl, and VExt. To select one of these voltages, simply use a jumper to short the pins next to the appropriate voltage on the VDD source connector
- 3.3V – The power voltage to the memory is 3.3V. The target power pins of the Promira platform, Cheetah adapter, or Aardvark adapter supply 5V to the board voltage regulator.
- VTgt – The power voltage to the memory is 3.3 V or 5V, which is supplied directly from the target power pins of the Promira platform, Cheetah adapter, or Aardvark adapter.
- VLvl – The power voltage to the memory is 0.9 V - 3.3 V, which is supplied directly from the I/O power pins of the Promira platform.
- VExt – The power voltage to the memory is from external 0.9 V - 5 V power supply that is connected to the External connector (J1) pins 13, 15 (VExt).
3.4 Powering the EEPROM Socket Board
The EEPROM Socket Board provides 0.9 V - 5 V to the target device from the adapter or from external source. If the power source to the EEPROM Socket Boards is the adapter, then the Promira platform, Cheetah adapter or Aardvark adapter must be configured to send target power to the board. This can be accomplished via the Rosetta Language Bindings, the Flash Center software, the Control Center Software or the Cheetah GUI Software. When powered-on, the board's Power LED will be lit.
3.5 Cross-Connecting Adapters
When cross-connecting two adapters, the board must be powered on. Otherwise, results may be unpredictable. If you experience problems, please make sure that the Power LED on the board is lit.
4 Programming a Device
I2C/SPI EEPROM and Flash memories can be programmed using the Flash Center Software in conjunction with Promira platform, Aardvark adapter or a Cheetah adapter. Detailed technical information about all these products can be found on Total Phase's website.
4.1 Inserting and Removing Device
To program a chip, insert the chip into the appropriate socket. Please note that all the sockets are cross-connected, so it is only possible to use one socket at a time.
Whenever handling chips, always be sure to follow safe handling procedures to ensure that the chips are not damaged.
4.1.1 DIP8
To insert a DIP8 chip, simply align the pins with the socket and firmly press the chip into the socket.
To remove a DIP8 chip, we recommend that a DIP extractor tool is used to prevent damage to the chip and its pins.
4.1.2 SOIC8 and TSSOP8
Both the SOIC8 and TSSOP8 sockets are zero insertion force sockets and work on the same principle.
To insert a chip:
- Press down on the top of the socket to raise the contact pins.
- While pressing down on the socket, carefully place the chip into the socket and make sure that the orientation of the chip is correct (pin 1 should always be in the top left corner).
- Once the chip is in place, release the top of the socket to allow the contact pins to drop and hold the chip in place.
At this point, the chip should be held securely in place. Please make sure that all the contact pins have made contact with the correct pins on the chip.
When removing the chip, we recommend using a vacuum pickup tool to prevent damage to the chip and its pins.
To remove a chip:
- Press down on the top of the socket to raise the contact pins.
- Carefully remove the chip using a vacuum pickup tool or equivalent tool.
- Release the top of the socket.
4.2 Connecting the Pins
Since different chips have different pin configurations, the EEPROM Socket Board includes 8-pin split ribbon cable to allow you to connect the pins to the correct sources.
In the top left side of the board, you will notice that there is a graphic representation of a chip with numbered pins from 1 to 8 (Figure 10). Along both sides of the drawing are two banks of 4-pin headers. These banks are connected to the eight pins of the chip in the socket. The pins of the chip should be connected to the appropriate sources as described by the chip's datasheet.
Various sources are provided around the chip diagram. Along the top of the chip are five pins for VDD and along the bottom of the chip are five pins for GND. To the left of the chip are sources for the I2C and SPI pins. Each source is labeled along the left.
4.3 Powering the Device
To configure the power source to the memory, select one of the four voltage options (3.3V, VTgt, and VLvl, VExt) on the VDD source connector (JP1).
4.3.1 External Power Source
It is possible to use an external power supply to provide power to the target chip. To use an external power source, use a jumper to short the pins next to VExt (position 4) on the VDD source connector (JP1). Power should be applied to the VExt pins on the External connector (J1).
4.4 SPI Slave Select
4.4.1 Connecting SS
Some SPI-based memory chips do not require the use of the Slave Select pin. In these cases, the SS pin can be disconnected. To do this, simply remove the jumper from the SS Connect connector (J3).
4.4.2 SS Pull-down/Pull-up Resistors
The EEPROM Socket Board provides the ability to either pull-down or pull-up the Slave Select line depending on the requirements of the target device by using a jumper to short pins on J4 connector.
To pull SS down, short pins 1 and 2.
To pull SS up, short pins 2 and 3.
