Analog Devices Inc. ADSP-2183KSTZ-210

Overview

ADSP-2183KSTZ-210 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 (26.32 MHz crystal), 52 MIPS sustained performance, 80 KB on-chip RAM (16K × 24-bit program + 16K × 16-bit data), dual serial ports with hardware companding, and 128-lead LQFP packaging. 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-2183KSTZ-210 datasheet, ADSP-2183KSTZ-210 pinout, ADSP-2183KSTZ-210 application, or ADSP-2183KSTZ-210 equivalent, key selection criteria include its 3-bus Harvard architecture enabling dual operand fetch per cycle, zero-overhead looping capability, programmable 16-bit interval timer with prescaler, ICE-Port™ emulator interface for in-system debugging, and support for automatic booting from byte-wide EPROM via BDMA port.

Technical Context

The ADSP-2183KSTZ-210 implements the ADSP-2100 family base architecture with three independent computational units-ALU, MAC (40-bit accumulator), and barrel shifter-interconnected via a dedicated result (R) bus. Its two data address generators (DAGs) support circular buffering and modulo addressing with four pointer registers each.

It integrates five internal buses (PMA, PMD, DMA, DMD, R) shared across external interfaces: 16-bit internal DMA port for direct on-chip memory access, 8-bit byte DMA port supporting up to 4 MB of external byte memory, and separate I/O memory space with 2048 locations. Serial ports SPORT0 and SPORT1 operate synchronously with optional A-law/µ-law companding per CCITT G.711.

FAQ

What clock sources does the ADSP-2183KSTZ-210 support?

The ADSP-2183KSTZ-210 supports both a 26.32 MHz crystal connected across CLKIN/XTAL pins and an external TTL-compatible clock signal applied to CLKIN only. When using an external clock, it must run at half the instruction rate (13.16 MHz for 19 ns cycle time), and XTAL must be left unconnected. The internal oscillator automatically stabilizes within 4096 CLKIN cycles after power-up.

How does the ADSP-2183KSTZ-210 handle booting from external memory?

The ADSP-2183KSTZ-210 supports automatic booting from byte-wide external memory (e.g., EPROM) via its Byte DMA (BDMA) port. Upon reset with MMAP = 0, it executes a built-in boot loader that transfers program code from external byte memory into on-chip program RAM before starting execution at address 0x0000. This eliminates need for external boot ROM logic.

Can the ADSP-2183KSTZ-210's serial ports operate independently with different frame formats?

Yes, SPORT0 and SPORT1 on the ADSP-2183KSTZ-210 have independent framing control registers, allowing each port to operate in distinct modes-e.g., SPORT0 in 24-word TDM for voice channels while SPORT1 handles frameless 16-bit audio streaming. Each port supports separate transmit/receive frame sync polarity, pulse width, and clock source (internal or external).

What is the function of the ICE-Port™ interface on the ADSP-2183KSTZ-210?

The ICE-Port™ interface on the ADSP-2183KSTZ-210 is a 14-pin dedicated emulation port enabling full-speed in-circuit debugging without removing the device from the target board. It supports up to 20 hardware breakpoints, real-time register/memory inspection, instruction-level stepping, and C source-level debugging via compatible EZ-ICE® emulators.

Does the ADSP-2183KSTZ-210 support power-down mode with wake-up via external interrupt?

Yes, the ADSP-2183KSTZ-210 supports hardware-initiated power-down via the PWD pin and software-initiated power-down via the PWD bit. Wake-up is triggered by any enabled external or internal interrupt-including IRQ2, SPORT receive, or timer expiration-with guaranteed execution resumption within 300 CLKIN cycles. The PWDACK pin asserts to confirm entry into power-down state.
