The ADSP-21065LCSZ-240 is a 60MHz, 32-bit fixed- and floating-point SHARC digital signal processor manufactured by Analog Devices. It combines high-performance signal processing, 544Kbit of on-chip SRAM, DMA control and multiple external interfaces in a 208-lead MQFP package.

Although Analog Devices has discontinued the ADSP-21065L family, the original ADSP-21065LCSZ-240 is still required for the maintenance and continued production of legacy industrial, audio, communications and measurement equipment.

ADSP-21065LCSZ-240 Specifications

ADSP-21065LCSZ-240 Replacement

Analog Devices lists ADSP-21569BBCZ8 as the suggested replacement for ADSP-21065LCSZ-240.

However, the ADSP-21569BBCZ8 is not pin-to-pin compatible with the ADSP-21065LCSZ-240. Analog Devices states that both hardware and software redesign are required.

Before selecting a replacement, engineers should compare:

PCB footprint and pin assignment

Supply voltage and power architecture

Memory organization

Peripheral interfaces

Boot configuration

SHARC software and development tools

Real-time processing performance

System qualification requirements

For repair or continued production of an existing design, using the original ADSP-21065LCSZ-240 can help avoid an immediate redesign when remaining system life and project requirements justify obsolete-part sourcing.

Frequently Asked Questions

Is ADSP-21065LCSZ-240 discontinued?

Yes. Analog Devices has classified the ADSP-21065L family as obsolete. The last-time-buy date for ADSP-21065LCSZ-240 was February 28, 2025, and the last-time-ship date was February 27, 2026.

What is the operating speed of ADSP-21065LCSZ-240?

The exact ADSP-21065LCSZ-240 ordering code has a 60MHz instruction rate. The “-240” version should not be confused with the faster “-264” versions in the ADSP-21065L family.

What package does ADSP-21065LCSZ-240 use?

ADSP-21065LCSZ-240 is supplied in a 208-lead MQFP package measuring 28 × 28mm. Package compatibility should be checked carefully when replacing the device.

What is the temperature range of ADSP-21065LCSZ-240?

The specified case-temperature range is −40°C to +100°C, making this ordering code suitable for extended-temperature legacy applications.

Is ADSP-21569BBCZ8 a drop-in replacement?

No. ADSP-21569BBCZ8 is the replacement suggested by Analog Devices, but it is not pin-compatible with ADSP-21065LCSZ-240. Hardware and software redesign are required.

Is ADSP-21065LCSZ-240 the same as ADSP-21065LKSZ-264?

No. They belong to the same ADSP-21065L family but have different speed and temperature grades. ADSP-21065LCSZ-240 is rated at 60MHz with a −40°C to +100°C case-temperature range, while ADSP-21065LKSZ-264 is a 66MHz commercial-temperature version.
