Harris Corporation HSP45240GC-40

The HSP45240 creates block-oriented memory-address sequences for DSP and image-processing work. A 24-by-24 crosspoint switch remaps output address bits for patterns such as FFT bit reversal. The same device can be configured as two independent 12-bit sequencers, with programmable delay on twelve outputs and a processor interface for setup.

The 1997 manufacturer-authored ordering table specifies HSP45240GC-40 as a 68-lead PGA, drawing G68.A. The catalog's 68-BCPGA matches the local registered normalized package name, recorded in workbook row 713 in the immediately preceding batch. The PGA bottom view differs from the PLCC top view; verify ceramic body size, keying, pin grid and socket against G68.A and the shipped lot.

Mechanical checks

• Match G68.A grid and bottom-view orientation.
• Check socket/key and pin pitch.
• Inspect ceramic body and pin condition.

The registered 68-BCPGA JPG is absent locally; keep the page unpublished.

The manufacturer's PGA bottom view identifies D0-D6, CS, A0 and WR for programming; CLK and RST for timing and reset; STARTIN, STARTOUT and DLYBLK for sequence control; ADDVAL, BUSY, BLOCKDONE and DONE for status; and OUT0-OUT23 with OEH/OEL for address outputs. Use the letter-number PGA grid in the controlled diagram. A PLCC pin number cannot be transferred to this package.

Confirm all G68.A coordinates and the supplied lot's orientation before schematic release.

Timing limits apply only under the manufacturer's stated loading and test conditions.

No LCDChip internal alternate is linked or approved. Harris listed GC-33 and GC-50 PGA speed grades and JC-40 PLCC. GC-33 is slower; GC-50 needs electrical and procurement checks; JC-40 has a different package. Validate programming behavior, reset, output loading, clock margin, G68.A grid and temperature grade before any substitution.

Harris' historical product guide and the 1997 Intersil HSP45240 data sheet list exact GC-40 in a commercial 68-lead PGA, G68.A. The later Renesas-hosted family data sheet includes -40 electrical timing but presents the JC PLCC package in its reduced ordering table. Keep the original GC package document with the device's traceability records.

Check the exact Harris GC-40 marking, date/lot code, original ceramic PGA and pin condition. Catalog stock and base price are separate commercial fields. Indexed exact-code sellers disagree on stock and quantity pricing; secure a dated authorized quote and confirm lot provenance before updating inventory terms or publishing.

Keep this item in manual review. Restore the 68-BCPGA JPG, verify G68.A coordinates and the supplied lot, reconcile exact-code authorized stock and tier pricing, and repeat database and rendered-page checks. No release or drop-in substitution is approved.
