Analog Devices Inc. ADSP-2183KCAZ-210

Overview

ADSP-2183KCAZ-210 from Analog Devices is a 3.3 V, 26.32 MHz fixed-frequency DSP microcomputer with 16K × 24-bit on-chip program RAM, 16K × 16-bit on-chip data RAM, and dual synchronous serial ports (SPORT0/SPORT1). It delivers 52 MIPS sustained performance with single-cycle instruction execution and zero-overhead looping, targeting real-time audio processing, telecom channel coding, and embedded control in portable instrumentation.

For engineers reviewing the ADSP-2183KCAZ-210 datasheet, ADSP-2183KCAZ-210 pinout, ADSP-2183KCAZ-210 application, or ADSP-2183KCAZ-210 equivalent, key selection criteria include its 128-lead LQFP package, 19 ns instruction cycle time, byte DMA port for EPROM booting, ICE-Port™ emulator interface, and power-down recovery within 300 CLKIN cycles.

Technical Context

The ADSP-2183KCAZ-210 implements the ADSP-2100 base architecture with three independent computational units (ALU, MAC, shifter), two data address generators (DAG1/DAG2), and a zero-overhead program sequencer supporting conditional jumps and subroutine calls in one cycle. Its 3-bus Harvard architecture enables simultaneous dual operand fetches - one from program memory and one from data memory - per instruction cycle.

It integrates dedicated hardware for A-law/µ-law companding per CCITT G.711, programmable 16-bit interval timer with prescaler (TSCALE), and 13 programmable flag pins (3 outputs only, 8 bidirectional). The device supports automatic booting from byte-wide external memory via BDMA and transparent access to on-chip RAM through the 16-bit internal DMA (IDMA) port.

Key Specifications

Pinout & Package

ADSP-2183KCAZ-210 is housed in a 128-lead LQFP package (14 mm × 14 mm, 0.4 mm pitch) with 11 ground pins, 6 VDD pins, and dedicated signal groups for address (14-bit), data (24-bit multiplexed with upper byte address), serial ports (SPORT0/SPORT1, 5 pins each), IDMA port (16-bit address/data + 5 controls), and power-down control (PWD/PWDACK).

FAQ

What clock source options does the ADSP-2183KCAZ-210 support?

The ADSP-2183KCAZ-210 accepts either a 26.32 MHz fundamental-mode quartz crystal across CLKIN/XTAL pins or a TTL-compatible 13.16 MHz square wave applied to CLKIN only (XTAL left unconnected). It contains no PLL; the internal instruction clock is derived directly from the oscillator circuit. Crystal start-up requires 4096 CLKIN cycles for stabilization, and the CLKOUT pin reflects the full instruction rate (26.32 MHz) when enabled via the SPORT0 autobuffer control register.

Does the ADSP-2183KCAZ-210 support in-system programming of its on-chip program memory?

No, the ADSP-2183KCAZ-210 does not support in-system programming of its 16K × 24-bit on-chip program RAM. Program code is loaded at power-up via automatic booting from external byte-wide memory (e.g., EPROM) through the BDMA port or via the IDMA port during runtime. The on-chip program memory is SRAM - volatile and writable only under processor control during active execution, not via JTAG or dedicated programming interfaces.

How many external interrupt sources can be simultaneously active on the ADSP-2183KCAZ-210?

The ADSP-2183KCAZ-210 supports up to six concurrently accessible external interrupt sources: IRQ2 (edge- or level-sensitive), IRQL0 and IRQL1 (level-sensitive), IRQE (edge-sensitive), plus IRQ0 and IRQ1 routed through SPORT1's reconfigured pins. All eleven total interrupts (six external + five internal) are prioritized and individually maskable via the IMASK register, except the nonmaskable power-down and reset interrupts.

Can the ADSP-2183KCAZ-210 execute code directly from external program memory?

No, the ADSP-2183KCAZ-210 cannot execute instructions directly from external program memory. Its program memory space is strictly mapped to on-chip 16K × 24-bit RAM. External memory accessed via the BDMA or IDMA ports serves only for data transfers and program overlays - code must be loaded into on-chip program RAM before execution. The PMOVLAY register enables overlay of external memory into the program address space for data access only, not instruction fetch.

What is the function of the FL0, FL1, and FL2 pins on the ADSP-2183KCAZ-210?

The FL0, FL1, and FL2 pins on the ADSP-2183KCAZ-210 are dedicated output-only flag signals used for system-level handshaking, status indication, or triggering external logic. Unlike the eight bidirectional PF[7:0] pins, these three flags cannot be configured as inputs. They are controlled exclusively by the processor's flag register and provide deterministic, low-latency signaling - commonly used to assert DMA request acknowledgments, indicate filter completion, or synchronize with external ADC/DAC peripherals.
