HP E2476A MPC 860/821 Preprocessor

Product Summary

The HP E2476A preprocessor interface allows easy connection of an HP logic analyzer to your Motorola MPC 860/821 BGA target system for real-time analysis. With the preprocessor solution, you don't need to design special debug connectors into your target system.

The HP E2476A solution consists of the following:

HP E2476A preprocessor

HP E5355A 357-pin BGA probing kit

HP E2476-87602 extender

three HP E5346A high-density termination adapters

Product Features

• In State-per-clock mode, the analyzer captures the processor state on every rising edge of the CPU clock.
• In State-per-transfer mode, the analyzer captures only those states in which the transfer acknowledge signal (TEA) is asserted. This mode will filter out wait and idle states. The inverse assembler only works in this mode.
• In Timing mode, timing analysis is supported. All processor signals are presented to the logic analyzer unbuffered.
• With Target Signal Timing, data must be valid for a 3.5 ns window with respect to the logic analyzer clock. The analyzer captures the data on the rising edge of the clock. There is a 1.25 ns propagation delay between the target and mounted preprocessor for DSDI, DSDO, and DSCK signals.

Product Specifications

Supported Microprocessors

Pods Required

Six 16-channel logic analyzer pods are required for inverse assembly. These six pods are connected to three HP E5346A termination adapters included with the preprocessor.

Three additional HP E5346A high density termination adapters are required to probe all signals on the processor for a total of 12 analyzer pods. Additional HP E5346A adapters must be purchased separately.

The HP E5355A BGA Probing Kit

The HP E5355A BGA probing kit includes the following:

Two surface mount BGA sockets

Soldering kit

Instructions

The user must solder the provided BGA socket onto the target system in place of the processor. Soldering instructions are included with the preprocessor.

Optional Accessories

HP E2476-87602 Extender

HP E5346A High density termination adapter

"Keep Out" Area

The E2476A preprocessor requires a minimal amount of "keep out" space around the processor. The preprocessor also has an overhang as shown in figure 3 Preprocessor Dimensions of the literature Solutions for the Motorola MPC 800 Embedded Power PC Microprocessor Family (HP Lit. # 5965-5053E). The maximum hight of components under the preprocessor in this area cannot exceed 19mm or .75 in.

If components are too high for the clearance, order the HP E2476-87602 extender to add an additional .25 inches of clearance. Do not exceed two extenders for use with the HP E2476A preprocessor.

Optional Connection Method

If system constraints won't allow the preprocessor interface to be used, you may design high-density AMP Mictor connectors into your target system for connection to the processor signals. The HP E2477A offers configuration files and an inverse assembler like the preprocessor interface.

Three HP E5346A high-density termination adpaters are required for inverse assembly. The AMP Mictor connectors may be located around the processor as shown in figure 2.

Refer to the HP E5346A High Density Termination Adapter" Pub 5965-5475E technical specifications data sheet for more information. Contact your HP representative for signal routing information.

AMP connectors can be purchased directly from AMP or from HP. Five AMP connectors and recommended support shrouds are included in the HP E5346-68701 connector kit.
