Product details
Overview
ADSP-2183KST-133 from Analog Devices is a 16-bit fixed-point DSP microcomputer optimized for real-time digital signal processing, featuring a 19 ns instruction cycle time (52 MIPS), 16K × 24-bit on-chip program RAM, 16K × 16-bit on-chip data RAM, dual serial ports (SPORT0/SPORT1), and 16-bit internal DMA port. It serves as the core processor in audio codecs, telecom channel banks, and embedded control systems requiring deterministic low-latency computation.
For engineers reviewing the ADSP-2183KST-133 datasheet, ADSP-2183KST-133 pinout, ADSP-2183KST-133 application, or ADSP-2183KST-133 equivalent, key selection criteria include its 128-lead LQFP package, 3.3 V operation, power-down mode with 300-cycle recovery, dual-operand fetch capability per cycle, and ICE-Port™ emulator interface for in-system debugging.
Technical Context
The ADSP-2183KST-133 implements the ADSP-2100 family base architecture with three independent computational units-ALU, MAC, and shifter-each operating on 16-bit data with 40-bit accumulation in the MAC. Its 3-bus Harvard architecture enables simultaneous program address, data address, and result bus activity per cycle.
It integrates two dedicated data address generators (DAG1/DAG2) supporting modulo addressing for circular buffers, zero-overhead looping via hardware loop counters, and conditional execution. The processor supports bit-manipulation instructions (bit set/clear/toggle/test), biased rounding, and global interrupt masking-extensions beyond baseline ADSP-2100 compatibility.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Instruction Cycle Time | 19 ns at 3.3 V - enables 52 MIPS sustained throughput with single-cycle instruction execution |
| On-Chip Program Memory | 16K × 24-bit RAM - stores both instructions and constants; allows dual-operand fetch (one from PM, one from DM) per cycle |
| On-Chip Data Memory | 16K × 16-bit RAM - includes 32 memory-mapped registers and supports circular buffer addressing via DAGs |
| Serial Interfaces | Two double-buffered SPORTs - support A-law/μ-law companding per CCITT G.711, frame sync, and multichannel TDM on SPORT0 |
| Power Management | Hardware/software power-down mode - enters ultra-low-power state with 300 CLKIN-cycle wake-up latency and PWDACK signaling |
| System Interface | 16-bit internal DMA port + byte DMA port - provides transparent access to on-chip RAM and 4 MB external byte memory space |
| Interrupt Architecture | 6 external + 7 internal interrupts - fully maskable except power-down; supports nested servicing with 12-level hardware stack |
Pinout & Package
ADSP-2183KST-133 is packaged in a 128-lead LQFP (14 mm × 14 mm, 0.4 mm pitch) with 11 ground pins, 6 VDD pins, and dedicated power/ground pairing for noise reduction in high-speed DSP operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| ADDR[13:0] | Address Output | 14-bit multiplexed address bus for program/data/byte/I/O spaces - requires external latch for full 24-bit addressing |
| DATA[23:0] | Data I/O | 24-bit bidirectional data bus; upper 8 bits double as byte-space address lines for BDMA port addressing |
| SPORT0[4:0] | Serial Port 0 I/O | Five-pin synchronous serial interface supporting TDM, framing, and hardware companding - used for primary audio stream I/O |
| SPORT1[4:0] | Serial Port 1 or Flag/IRQ | Configurable: either second serial port or dual IRQ inputs (IRQ0/IRQ1) plus FLAG_IN/FLAG_OUT for system signaling |
| IDMA[15:0] | Internal DMA Address/Data | 16-bit multiplexed bus for high-speed direct access to on-chip RAM - eliminates wait states during memory transfers |
| PWD / PWDACK | Power-Down Control | Active-high PWD initiates hardware power-down; PWDACK asserts when dormant state is entered - critical for battery-powered sleep/wake protocols |
Key Features
| Feature | Design Value |
|---|---|
| Three-Unit Parallel Execution | ALU, MAC, and shifter operate concurrently per cycle - enables single-cycle multiply-accumulate plus data move plus address update |
| Dual DAG Architecture | Two independent data address generators each managing four pointers with modulo length - essential for FFT, FIR, and circular buffer algorithms |
| ICE-Port™ Emulator Interface | 14-pin dedicated debug port supporting in-circuit emulation without target board modification - enables real-time register/memory inspection and breakpoint control |
| Flexible Boot Options | Supports automatic boot from byte-wide EPROM via BDMA or internal DMA port - eliminates external boot ROM dependency in cost-sensitive designs |
| Low-Power Idle Modes | Three configurable states: standard IDLE, Slow IDLE (with 16/32/64/128 clock divisor), and Power-Down - reduces active current to <100 μA in dormant state |

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-133 | Higher clock grade (35.7 MHz), integrated EZ-ICE debug interface, same ADSP-2100 ISA but no byte DMA port | Targeted for evaluation and rapid prototyping; lacks BDMA for EPROM boot - requires external boot ROM or JTAG initialization | Select when development speed and debug visibility outweigh production cost and boot flexibility |
| TMS320VC5402PGE100 | 100-MIPS C54x core, 16K × 16-bit RAM, 32-bit ALU, different instruction set - not code-compatible | Requires full software porting; superior power efficiency in idle modes but no native ICE-Port support | Select when migrating legacy C54x code or prioritizing lower active power over ADSP-2100 ecosystem tooling |
Compared with ADSP-2183KST-133, ADSP-2189MSTZ-133 trades boot flexibility for integrated debug capability, while TMS320VC5402PGE100 offers higher peak MIPS but demands complete firmware rework and lacks hardware companding - making ADSP-2183KST-133 optimal for cost-sensitive, audio-centric designs requiring drop-in ADSP-2100 compatibility.

FAQ
What is the maximum external memory capacity supported by ADSP-2183KST-133?
The ADSP-2183KST-133 supports up to 4 MBytes of external byte memory via its Byte DMA port, using 8 data lines as extended address bits. For program and data overlays, it accesses two 8K external segments (16K total) through the 24-bit external address bus. The internal 16K-word program RAM and 16K-word data RAM remain accessible without wait states, making ADSP-2183KST-133 suitable for applications requiring fast local storage with scalable off-chip expansion.
Does ADSP-2183KST-133 support in-circuit debugging without hardware modifications?
Yes, ADSP-2183KST-133 integrates on-chip emulation support with a dedicated 14-pin ICE-Port™ interface. This allows full in-target debugging-including breakpoints, register/memory inspection, and instruction-level emulation-without removing the device from the target board or adding adapters. The ICE-Port requires only a standard EZ-ICE connector, enabling ADSP-2183KST-133 to be debugged in final production hardware layouts.
Can ADSP-2183KST-133 boot directly from an 8-bit EPROM?
Yes, ADSP-2183KST-133 supports automatic booting from byte-wide external memory such as EPROM via its Byte DMA port. When BMODE = 0 and MMAP = 0, the processor initializes by loading the first 16 words from external byte memory into on-chip program RAM. This eliminates the need for external boot ROM logic, simplifying system design and reducing BOM cost for ADSP-2183KST-133-based products.
What are the power management modes available on ADSP-2183KST-133?
ADSP-2183KST-133 provides three low-power modes: Power-Down (ultra-low standby current, 300-cycle wake-up), Idle (clock-gated, interrupt-wakeup), and Slow Idle (programmable clock divisor of 16/32/64/128). All modes retain on-chip RAM contents. The PWD pin and software power-down force bit initiate Power-Down; IDLE and IDLE(n) instructions control the other two - making ADSP-2183KST-133 well-suited for battery-powered portable DSP applications.
Is ADSP-2183KST-133 pin-compatible with other ADSP-2100 family members?
No, ADSP-2183KST-133 is not pin-compatible with earlier ADSP-2100 series devices due to its expanded peripheral set - including dual SPORTs, 16-bit internal DMA port, byte DMA controller, and 13 flag pins. While instruction-set compatible with the ADSP-2100 family (with extensions), its 128-lead LQFP footprint and signal allocation differ significantly from ADSP-2101/2105/2106 packages - requiring unique PCB layout for ADSP-2183KST-133 integration.
