Product Details
HSP45256GC-33 - 256-Tap Binary Correlator
HSP45256GC-33 is the Harris 33 MHz commercial-grade binary correlator in an 85-lead ceramic pin-grid array. Harris ordering information identifies this exact suffix, speed, temperature range and package.
Match the complete suffix and package to the supplied lot before design or replacement.
Overview
The HSP45256 performs high-speed binary correlation with a reconfigurable array of 256 taps. It supports one- or two-dimensional correlation with selectable data precision and effective window length. Several devices may be cascaded when an application needs a longer correlation span.
Key Advantages
Configurable correlation
One-bit reference data can be correlated with 1-, 2-, 4- or 8-bit input data.
Flexible dimensions
Supports one- or two-dimensional operation and can be configured as two separate correlators.
Cascade capability
Multiple chips can extend correlation length, with programmable output delay aiding alignment.
Buffered updates
Double-buffered mask and reference registers permit the next configuration to be loaded during operation.
Feature Summary
Tap organization
Eight 32-tap stages form the 256-tap correlation array.
Masking
Selected taps can be excluded from the score by the programmable mask.
Score processing
Weight-and-sum logic and an offset register condition the correlation result.
Control interface
A standard microprocessor interface loads the device's control registers.
Package & Footprint
Harris ordering information lists HSP45256GC-33 in an 85-lead PGA. The LCDChip catalog calls the case 85-BCPGA, and the package register maps it to 85-BCPGA.jpg. That local JPG is absent, so the artwork and board footprint are unverified.
- Confirm the 85-pin grid, keying and pin-one position from the manufacturer drawing.
- Compare socket or PCB hole pattern with the actual supplied part.
- Inspect ceramic body, pins and marking before insertion.
Do not publish until the registered JPG and mechanical fit are verified.
Pin Functions
The manufacturer data sheet defines the 85-pin PGA pinout. Use that numbered drawing for wiring; the functional groups below are not a pin-number substitute.
Input and reference
DIN and DREF groups deliver data and reference information to the correlation array.
Control
DCONT and address/control pins configure the microprocessor interface.
Results and cascade
DOUT, CASIN and CASOUT groups support result transfer and multi-device chaining.
Clock and supply
Connect timing, VCC and ground pins according to the original electrical specification.
Verify every signal number in the original Harris/Intersil pinout before a board change.

Electrical timing, current, dimensions and pin assignments must be taken from the original data sheet for the supplied order code.
Replacement Considerations
Other HSP45256 grades or PLCC versions are not automatic replacements. Compare 33 MHz timing, commercial temperature range, 85-pin PGA geometry, power limits and firmware configuration. No internal alternative model link is offered without a verified database match and engineering equivalence check.
Manufacturer Information
The Harris product selection guide names HSP45256GC-33 and lists its 0°C to +70°C commercial range and 85-lead PGA. The Harris/Intersil HSP45256 data sheet describes the correlation array, interfaces, electrical conditions and pinout. Current distributor listings identify the exact ordering code but do not replace original manufacturer specifications.
Applications
Spread-spectrum systems
Correlation and synchronization in communications receivers.
Radar and sonar
Pattern correlation across sampled signal windows.
Pattern recognition
Character or bit-pattern matching with programmable masks.
Error-correction processing
Correlation steps in legacy digital-signal-processing equipment.
Quality & Authenticity
Inspect the full HSP45256GC-33 marking, package, date and lot code, ceramic body, pin straightness, storage and traceability. Distributor availability does not by itself establish a qualified lot, electrical test history or current production status.
FAQ
What does the HSP45256GC-33 do?
It performs configurable binary correlation using up to 256 taps.
Can the device run two correlations?
The family supports a two-correlator configuration, subject to the documented window sizes and control settings.
What does GC-33 identify?
Harris lists this exact code as its commercial 33 MHz version in an 85-lead PGA.
Is the package image verified?
No. The registered 85-BCPGA.jpg is missing locally.
Engineering Notice
Keep this detail under review until the 85-BCPGA JPG, actual footprint, supplied-lot marking and current qualified distributor price are verified. The distributor quote is not a verified replacement for the site's catalog price. Do not publish while any gate remains open.
