Analog Devices Inc. ADSP-1410JN

The ADSP-1410 provides a 16-bit Y address output port and a 16-bit D data port. Internal registers hold pointers, offsets, comparison values and initialization values. It can issue an address, modify the pointer and test a loop boundary within an instruction cycle. The JN order code appears in an original Analog Devices DSP products data book.

• Dedicated hardware for data-memory address generation.
• 16-bit address path with higher-precision operating options.
• Thirty 16-bit internal registers organized by address-generation role.
• Address arithmetic, comparison, shift and bit-reversal support.
• Programmable pre-update and post-update addressing.

The manufacturer data book identifies sixteen address registers, six offset registers, four compare registers and four initialization registers. A 16-bit ALU and comparator support offset addressing and loop-boundary tests. The device supports direct data-port selection, an alternate instruction register and single- or double-precision operating modes. Consult the original instruction timing and control-register descriptions when integrating legacy microcode.

Analog Devices' ordering table explicitly maps ADSP-1410JN to a 48-pin plastic DIP, package outline N-48A, for commercial ambient operation. The catalog says 48-DIP, but the local package-registry mapping is unconfirmed and the 48-DIP JPG is absent. Check socket width, lead pitch, pin-one orientation and the controlled N-48A drawing before board work.

Assembly checks

• Match the 48-pin N-48A outline to the target socket.
• Confirm supply and clock pin locations.
• Apply ESD precautions when handling legacy stock.

The expected local 48-DIP JPG is missing.

The manufacturer describes a 16-bit Y address output port and a 16-bit D data port, together with instruction, clock and control connections. DSEL can select external D-port data for an address operation. Exact pin numbers, drive conditions and control timing must be taken from the ADSP-1410JN package pin diagram, not inferred from another suffix.

Consult the manufacturer switching table for J-grade limits under the exact loading and supply conditions; do not substitute family headline timing for design limits.

No database-verified internal replacement is linked. Other ADSP-1410 grades may share architecture but can differ in timing, temperature range and package. ADSP-1401 is a microprogram sequencer, not a drop-in address-generator replacement. Validate pinout, microcode behavior, timing and mechanical fit before substitution.

The original Analog Devices DSP Products Data Book provides the ADSP-1410 functional description and explicitly lists the JN order variant. The Analog Devices Word-Slice user manual explains address-output and update modes. Archived documents establish historical functionality, but lot-specific authenticity and current supply terms require fresh supplier confirmation.

• Legacy digital signal and array processor data addressing.
• Address sequences for FFT, filtering and matrix routines.
• DMA-style address output through the D-to-Y path.

Confirm Analog Devices markings, JN suffix, package outline, date/lot code, storage and ESD history. The local catalog records 475 units, USD 24.66, minimum quantity 12 and no tiers. Broker pages repeat 475 units, while one quotes quantity 13-plus at USD 24.66 and others request a quote; this is not a verified current authorized price ladder. Catalog values are preserved pending supplier reconciliation.

Check J-grade switching limits, clock relationships, control sequencing, output loading, ESD handling and exact N-48A mechanical fit. The missing package JPG, unconfirmed registry mapping and unverified authorized stock/price tiers prevent publication.
