eprom programmer in circuit

In many circumstances it is highly desirable to work with an 8 pin serial eeprom or Motorola 68HC05/08/11 family microcontroller while it remains connected to the printed circuit board. To accomplish this, the programming instrument must not only generate the proper algorithms capable of accessing the part, but also be able to provide sufficient signal drive current such that the existing circuitry on the board does not interfere with reading and programming the device. The EPROM+ socket pin drivers use a push-pull output stage, which in nearly all cases, are capable of driving pins on a device while it remains soldered to the circuit board assembly.

To address connecting to a surface mount serial EEPROM "in-circuit" we offer two options; the "chip clip" (left) and the "probe set" (right). Each offers specific advantages depending upon the accessability and condition of the device leads. Both connect to the (#ASERSM1) in-circuit serial eeprom adapter (center) using a standard connector. This allows you to easily change the chip attachment mechanism choosing either the clip or the probes. If you are working with serial eeproms in an 8 pin DIP package we also offer a DIP CLIP which mates with the in-circuit adapter or a standard terminator board (see below).

CHIP CLIP

The chip clip provides the easiest and most direct method for attaching to a surface mounted serial eeprom. The clip contains 8 individual brass points which contact the eeprom leads once the clip is oriented and released. The spring loaded mechanism holds the clip firmly in place. A red dot indicates pin 1 on the part to assist in proper orientation. In order for the clip to function properly, the eeprom leads must be clean and there must be sufficient clearance between the package and the board for the jaw mechanism to attach.

DIP CLIP

The 8 pin DIP clip provides a fast, reliable connection to serial eeproms located in the larger through-hole package. The clip contains 8 individual brass pins which contact the eeprom leads once the clip is oriented and released. The spring loaded mechanism holds the clip firmly in place. A red dot indicates pin 1 on the part to assist in proper orientation. In order for the clip to function properly, the eeprom leads must be clean and there must be sufficient clearance between the package and the board for the jaw mechanism to attach.

STANDARD SURFACE MOUNT PROBE SET or PRECISION PROBE SET

The standard surface mount probe set (below) provides a positive lock connection to each pin of a surface mounted serial eeprom or 68HC05/08/11 family microcontroller. Using a micro pincher jaw, the probe tip is able to be placed in position to make a reliable contact with the device lead. Even if the device lead has contamination or protective residue, the probe tip is usually capable of penetrating the barrier and making contact with the underlying metal lead. This arrangement is an excellent complement to the clip for chips in hard to reach locations or which have interference from nearby components. Each probe is color coded (brown through gray) which correspond to the EIA (Electronics Industry Association) colors which reference the numbers 1 through 8. This makes connecting the probes to an 8 pin device intuitive and easy. For ultra small package connections you may wish to consider the precision surface mount probe set.

Both probe sets are compatible with the in-circuit serial eeprom adapter (#ASERSM1) and the asychronous communication adapters (#ACOM1 or #ACOM2) which supports the Motorola 68HC05/08/11 microcontroller families. The probe sets attach to the ACOM1 or ACOM2 using a standard terminator board (left). The standard terminator also includes pin for insertion into a DIP socket (center) or the ACOM1/2 adapter (right). Many applications use both serial eeproms and a 68HC family processors. The standard terminator allows a single probe set to support both technology families. NOTE: The standard terminator also allows the probe set and clips to be used with third part programming equipment however most third party programmers are not designed for in-circuit programming.
