Acculogic
offers a family of powerful, high speed IEEE 1149.1 (JTAG) compliant controllers based on
our proprietary bus controller JPCI and are designed for use in design verification,
production test and on-board device programming applications. |

All Controllers feature:
- Adaptive Clocking Technology
- High Performance plug & play
- JPCI 32-bit (IEEE 1149.1) bus controller
- Fast throughput f up to 125 Mbits/sec
- Up-to 25MHz programmable TCK rate
- 32 general purpose fully programmable parallel I/O channels
- 2MB cache multi-page memory behind TDI/TDO
- Two 24 bit analog channels
- Performs non-compliant test access port (TAP) operations
- Meets addressable scan port (ASP) requirements
- Supports industry standard vector formats SVF, JAM/STAPL, etc.
- Programmable logic levels (1.8V to 5.0V)
- Configurable to service multiple scan chains (up-tp 16) |

Adaptive Clocking Technology
Adaptive Clocking eliminates instabilities typically associated with boundary scan (JTAG)
operation at high clock rates (TCK) due to path delays. This proprietary and patented
design compensates for path delays allowing the JPCI controller to operate at the maximum
TCK rate supported by the target devices.
- Clocking flexibility to achieve highest throughput
- Automatic compensation for path delays from 10 nsec to 10 usec - with 10 nsec resolution
- Reliable high-speed operation over long cable lengths without the
use of Pods (system to
DUT)
- Cable length of up to 15 meters (40-50 feet)
Adaptive clocking eliminates the effects of path delay allowing the JPCI controller to be
located at an ergonomically suitable distance, up to 15 meters from the target. |

ScanMultiplier
ScanMultiplier
facilitates the programming and testing of up to 16 targets simultaneously. Its
intelligent, controller routes serial data streams to and from targets under program
control and allowing any number of channels (from 1 to 16) to be selected and operated in
sequence or in parallel by the user.
Two port and four port versions are available. |

ParallelRiter
ParallelRiter offers a powerful, easy to use solution for
parallel test and/or programming of circuit boards that do not support the IEEE 1149.1
standard.
ParallelRiter operates with Acculogic boundary scan controller cards and transforms the
generated serial stream to parallel data that is then applied to the target via test pads,
headers, connectors, etc.
ParallelRiter provides an external boundary scan chain that can be wrapped around the
device under test (DUT) to improve test fault coverage.
- 64 channels/card
- Bi-directional channels that can be tri-stated
- Dynamically configurable
- Clock rate of up to 20 MHz (TCK)
- Multiple card configuration
- Programmable voltage levels 3.3V and 5V
- PC based or stand alone (PCI and ISA) |
