Harris Corporation HSP48908VC-20

The HSP48908 processes raster-scan image data using on-chip row buffers and programmable 3 × 3 convolution kernels. It supports image filtering, edge detection and adaptive operations at video data rates. This legacy device needs its exact Harris revision and package drawing checked against the supplied lot before use in a new or repaired assembly.

The original Harris product-selection ordering table lists HSP48908VC-20 as a 100-lead MQFP, whereas the LCDChip catalog field is 100-BQFP and distributor records use both 100-BQFP and 100-MQFP labels. The two descriptors may refer to case and supplier package naming, but mechanical equivalence is not established. Obtain the controlled Q100x14x20 drawing and inspect the actual lot. The expected local 100-MQFP JPG is absent and the register mapping remains unverified.

Layout checks

• Confirm Harris VC package code and pin-one orientation.
• Reconcile 100-BQFP catalog wording with Q100x14x20 drawing.
• Check body, lead span, pitch and legacy lead finish.

Do not use the unverified image path for a published page.

The original HSP48908 pinout identifies DIN[7:0] as pixel inputs, CIN[9:0] as coefficient/data-control inputs, DOUT[19:0] as result outputs, and CASI/CASO buses for device cascading. CLK, FRAME, RESET, HOLD, OE and microprocessor control signals coordinate data flow. Use the 100-lead MQFP-specific top view, not the 84-lead PLCC/PGA pin numbers, for schematic capture.

Exact pin numbers and power-return assignments require the controlled VC package drawing.

Family-level features do not substitute for device-specific timing, supply and thermal limits.

No alternative is qualified or linked. Other HSP48908 speed and package variants can differ in clock rating, footprint and pinout. A proposed replacement must be checked for kernel timing, row length, signed-data handling, cascade signals, microprocessor register programming, supply level and complete mechanical outline.

Harris Semiconductor's original product guide names HSP48908VC-20 as a 100-lead MQFP commercial-temperature part. Archived Harris technical documentation describes the HSP48908 3 × 3 convolver architecture. Request the exact Harris-controlled revision, lot traceability and package drawing from the current supply chain before qualifying this legacy device.

Inspect the complete Harris marking, VC-20 suffix, date and lot codes, package lead finish and storage history. Obtain traceable inventory and a dated distributor quotation before relying on catalog price or availability. Site inventory and tiers are managed separately from this engineering content.

Keep this legacy product under manual review. Obtain the exact Harris-controlled data sheet and lot drawing, reconcile MQFP versus BQFP nomenclature, verify the local package register and JPG, and check a dated stock/price ladder. Publish only after electrical, mechanical, content and rendered-page checks all pass.
