Product details
Overview
ADSP-2183KSTZ-115 from Analog Devices is a 16-bit fixed-point DSP microcomputer optimized for real-time digital signal processing in audio, telecom, and industrial control systems. It delivers 52 MIPS sustained performance at 19 ns instruction cycle time (26.32 MHz crystal, 3.3 V), integrates 16K × 24-bit program RAM and 16K × 16-bit data RAM, and features dual serial ports (SPORT0/SPORT1), 16-bit internal DMA port, byte DMA controller, and programmable 16-bit interval timer.
For engineers reviewing the ADSP-2183KSTZ-115 datasheet, ADSP-2183KSTZ-115 pinout, ADSP-2183KSTZ-115 application, or ADSP-2183KSTZ-115 equivalent, key selection criteria include on-chip memory configuration (dual-port RAM), low-power operation modes (power-down with 300-cycle recovery), ICE-Port™ emulator support, and compatibility with ADSP-2100 family development tools including VisualDSP++ and EZ-KIT Lite.
Technical Context
The ADSP-2183KSTZ-115 implements the ADSP-2100 base architecture with three independent computational units (ALU, MAC, shifter), two dedicated data address generators (DAG1/DAG2), and a zero-overhead program sequencer supporting conditional execution and nested loops. Its 3-bus Harvard architecture enables simultaneous dual operand fetches - one from program memory and one from data memory - in every instruction cycle.
It supports hardware companding (A-law/µ-law per CCITT G.711) on both serial ports, automatic booting from byte-wide EPROM via BDMA, and transparent memory transfers using internal DMA (IDMA) and byte DMA (BDMA) controllers. The processor includes 13 programmable flag pins, six external interrupt inputs (configurable edge/level-sensitive), and ICE-Port™ for in-circuit emulation without target board modification.

Equivalent & Alternatives
The following parts are listed as comparable options for similar DSP microcomputer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADSP-2189MSTZ-215 | Higher clock speed (35.7 MHz), 128K bytes on-chip RAM, enhanced instruction set including bit-manipulation ops | Better suited for complex multi-algorithm systems (e.g., dual-band audio codecs); requires higher supply current | Select when >52 MIPS or larger on-chip memory is required; not pin-compatible due to different BGA footprint |
| TMS320VC5402PGE100 | TI C54x core; 100 MIPS @ 100 MHz, 16K × 16-bit RAM, McBSP serial ports, no integrated boot ROM | Stronger toolchain support for telecom standards (G.729, GSM); lacks hardware companding and ICE-Port™ | Choose for high-volume telecom infrastructure where TI ecosystem and licensing matter; requires external boot loader |
Compared with ADSP-2183KSTZ-115, ADSP-2189MSTZ-215 offers higher performance and memory but uses Mini-BGA packaging and lacks LQFP compatibility, while TMS320VC5402PGE100 provides greater raw MIPS and industry-standard McBSPs but requires external boot circuitry and lacks integrated power-down recovery optimization.

FAQ
What is the maximum operating frequency supported by ADSP-2183KSTZ-115?
The ADSP-2183KSTZ-115 operates with a 19 ns instruction cycle time, corresponding to a 26.32 MHz crystal input (which drives an internal 52.63 MHz clock). It does not support external clock inputs above this frequency, and its timing specifications are validated only up to this rated speed. Exceeding this limit may cause timing violations in internal bus arbitration or memory access, particularly affecting SPORT synchronization and IDMA transfers. Always verify setup/hold times against the ADSP-2183KSTZ-115 datasheet Rev. C timing diagrams.
Does ADSP-2183KSTZ-115 support in-system programming or booting from external memory?
Yes, ADSP-2183KSTZ-115 supports automatic booting from byte-wide external memory (e.g., EPROM or Flash) via its Byte DMA (BDMA) port, triggered on reset when MMAP = 0. It loads the first 64 words into on-chip program RAM and begins execution. The BDMA controller can then transparently fetch program overlays or coefficient tables from up to 4 MB of external byte memory without CPU intervention. No external bootloader IC is required.
How many interrupt sources does ADSP-2183KSTZ-115 support, and what types are available?
The ADSP-2183KSTZ-115 supports eleven maskable interrupts plus non-maskable power-down and reset. External sources include IRQ2 (edge/level-selectable), IRQL0/IRQL1 (level-sensitive), IRQE (edge-sensitive), and SPORT1-configurable IRQ0/IRQ1 - totaling up to six external interrupt pins. Internal sources are timer, SPORT0/SPORT1 transmit/receive, BDMA completion, and software interrupts. All vectors are fixed and prioritized per Table I in the datasheet.
Can ADSP-2183KSTZ-115 execute code from external program memory directly?
No - ADSP-2183KSTZ-115 executes only from its on-chip 16K × 24-bit program RAM. External program memory is accessed exclusively via overlay mechanism: PMOVLAY register selects between internal RAM or one of two 8K external segments mapped into addresses 0x2000–0x3FFF. Code must be loaded into on-chip RAM at boot or runtime via IDMA/BDMA; no direct execution from external bus is supported.
Is ADSP-2183KSTZ-115 pin-compatible with other ADSP-2100 family members like ADSP-2181 or ADSP-2185?
No - ADSP-2183KSTZ-115 is not pin-compatible with ADSP-2181 or ADSP-2185. While instruction-set compatible with the ADSP-2100 family, it features unique pin assignments for its dual SPORTs, IDMA port (16-bit multiplexed IAD bus), and ICE-Port™ signals. The 128-lead LQFP package differs in signal count and layout from ADSP-2181's 100-pin PQFP and ADSP-2185's 144-ball Mini-BGA. PCB redesign is required for substitution.
