ScProbe: JTAG/ debug connector and high density test points on PCB

ScProbe JTAG/ Background Debug Connector

Time to Read 1 min

No space for a 14 pin JTAG connector?
100'000 programming connectors for production are too expensive?

Here is the solution:
A reusable needle adapter which needs only 49 mm2 PCB estate. The connector on the target system/ PCB is essentially free of cost (15 test points, 2 position holes).

Features

Small footprint of only 49 mm2
Essentially free connector on target system (copper etch only)
15 pins, adapted to 16 pin industry-standard half-pitch connector
Layout with 0.2 mm (8 mil) design rules
Testpoints can be contacted with standard needle adapter in production
One-hand operation, like a syringe

Applications

R&D: JTAG/ background debugging
R&D: serial interfaces for logging/ debugging
R&D: processors/ Flash memory and CPLD/ FPGA programming
Manufacturing: programming for small lots when a needle adapter is not economically feasible
Service: software updates

Specifications

PCB Footprint	see PCB Footprint below
Maximum current per pin	0.5 A
Maximum voltage	100 V

Options

Replacement spring-loaded contacts
Interface PCB from 16 pin half-pitch connector to e.g. ADI-style JTAG and Freescale-style BDM

Application examples

ADI Blackfin JTAG, Freescale HCS08 BDM and LVTTL serial on one ScProbe
Freescale Coldfire JTAG and LVTTL serial on one ScProbe
Two Freescale HCS08 BDM and two LVTTL serial on one ScProbe
