Product details
Overview
ADSP-2188MKCA-300 from Analog Devices is a 75 MIPS fixed-point DSP microcomputer optimized for real-time signal processing, featuring 48K × 24-bit on-chip program RAM, 56K × 16-bit data RAM, dual synchronous serial ports (SPORT0/SPORT1), and 13.3 ns instruction cycle time at 2.75 V. It executes single-cycle instructions with zero-overhead looping and supports booting from byte-wide external memory in portable audio and telecom terminal applications.
For engineers reviewing the ADSP-2188MKCA-300 datasheet, ADSP-2188MKCA-300 pinout, ADSP-2188MKCA-300 application, or ADSP-2188MKCA-300 equivalent, key selection criteria include on-chip memory configuration (48K/56K split), LQFP-100 package compatibility, 2.75 V core voltage operation, SPORT hardware companding per G.711, and ICE-Port™ debug interface support for in-system emulation.
Technical Context
The ADSP-2188MKCA-300 implements the ADSP-2100 base architecture with three independent computational units-ALU, MAC, and shifter-enabling parallel operand fetches via 3-bus design. Its dual DAGs support circular buffer addressing with automatic modulo arithmetic, and the program sequencer delivers zero-overhead loops using internal loop counters and stacks.
It supports two operating modes: Full Memory Mode (14-bit address bus, 24-bit data bus) and Host Mode (16-bit IDMA port with address/data multiplexing), selected by Mode C pin at reset. Serial ports provide frame-synchronous I/O with configurable clock sources, A-law/µ-law companding, and interrupt-on-transfer capability.

Pinout & Package
ADSP-2188MKCA-300 is housed in a 100-lead LQFP (ST-100) package with 0.5 mm pitch and exposed thermal pad. Pin functions are mode-dependent: Full Memory Mode uses A13:A0 and D23:D0 for external memory interfacing; Host Mode repurposes pins for 16-bit IDMA port (IAD15:IAD0) with dedicated IWR/IRD/IAL/IS/IACK signals. All serial port, flag, and interrupt pins are software-configurable during runtime.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| RESET | Asynchronous processor reset input | Active-low signal initializing registers, disabling clocks, and forcing boot sequence; sampled synchronously |
| A13:A0 | Address output (Full Memory Mode) | 14-bit multiplexed address bus for program/data/byte/I/O memory spaces; shared with IDMA in Host Mode |
| D23:D0 | Data I/O (Full Memory Mode) | 24-bit bidirectional data bus; upper 8 bits serve as byte memory address lines in BDMA operations |
| SPORT0[4:0] | Synchronous serial interface | Five pins (SCLK0, RFS0, DR0, TFS0, DT0) supporting frame-synced full-duplex I/O with programmable clock generation |
| PF7:PF0 | Programmable I/O flags | Eight general-purpose bidirectional pins; concurrently support interrupt input and flag output when enabled |

FAQ
What is the maximum operating frequency and voltage specification for the ADSP-2188MKCA-300?
The ADSP-2188MKCA-300 operates with a 13.3 ns instruction cycle time, delivering 75 MIPS sustained performance at 2.75 V core supply (VDDINT). Its I/O voltage (VDDEXT) supports either 2.75 V or 3.3 V operation, and all input pins tolerate up to 3.6 V regardless of selected I/O mode. This dual-voltage flexibility enables interoperability with both legacy 2.75 V and modern 3.3 V peripheral logic without level-shifting circuitry.
Does the ADSP-2188MKCA-300 support hardware-based audio companding, and if so, which standards?
Yes, the ADSP-2188MKCA-300 supports hardware A-law and µ-law companding in both SPORT0 and SPORT1, compliant with CCITT Recommendation G.711. This offloads voice encoding/decoding from the main CPU, reducing instruction cycles required for PCM-to-logarithmic conversion in telephony applications. The companding is fully integrated into the serial port data path and requires no additional software overhead or external components.
How does the ADSP-2188MKCA-300 handle external memory interfacing in Full Memory Mode versus Host Mode?
In Full Memory Mode (Mode C = 0), the ADSP-2188MKCA-300 exposes A13:A0 and D23:D0 for direct connection to external program/data/byte/I/O memory spaces, supporting up to 4 MB addressing. In Host Mode (Mode C = 1), it configures 16 pins as the multiplexed IDMA port (IAD15:IAD0) with dedicated control signals (IWR, IRD, IAL, IS, IACK) for high-speed glueless access to on-chip RAM-ideal for master-slave DSP configurations where the ADSP-2188MKCA-300 acts as a peripheral co-processor.
What debug capabilities does the ADSP-2188MKCA-300 provide through its ICE-Port™ interface?
The ADSP-2188MKCA-300 integrates a 14-pin ICE-Port™ interface supporting full in-circuit emulation without removing the device from the target board. It enables real-time register and memory inspection, up to 20 hardware breakpoints, single-step or full-speed execution, PC upload/download, instruction-level boot emulation, and C source-level debugging via compatible EZ-ICE® tools. The compact connector footprint allows integration into final production PCB layouts.
Can the ADSP-2188MKCA-300 boot directly from external memory, and what interface options are supported?
Yes, the ADSP-2188MKCA-300 supports automatic booting from byte-wide external memory such as EPROM or flash via the BDMA port, or from external memory connected to the IDMA port in Host Mode. Boot configuration is controlled by MODE pins at reset, and the processor loads the first 32 words into program memory before beginning execution. This eliminates need for external boot ROM or host initialization firmware in standalone applications.
