Product details
Overview
ADSP-2111BG-80 from Analog Devices is a 16-bit fixed-point DSP microprocessor with on-chip 2K RAM program memory and 1K RAM data memory, featuring an integrated 16-bit host interface port (HIP), dual serial ports (SPORT0/SPORT1), and three edge- or level-sensitive interrupts. It executes instructions at 25 MIPS (40 ns cycle time) and targets real-time audio processing, telecommunication line cards, and host-coupled embedded control systems.
For engineers reviewing the ADSP-2111BG-80 datasheet, ADSP-2111BG-80 pinout, ADSP-2111BG-80 application, or ADSP-2111BG-80 equivalent, key selection considerations include HIP timing compatibility with 68000/80C51 hosts, 100-pin PGA package constraints, 5 V supply operation, and boot-source selection via BMODE pin.
Technical Context
The ADSP-2111BG-80 implements an enhanced Harvard architecture with three independent internal buses-program memory address (PMA), program memory data (PMD), and dual data memory buses (DMA/DMD)-enabling simultaneous instruction fetch and dual operand access. Its computational core integrates ALU, multiplier/accumulator (MAC), and shifter units connected via a 16-bit result (R) bus for single-cycle inter-unit data flow.
It supports zero-overhead looping via dedicated loop counters and stack, automatic booting from either external EPROM or host processor via HIP, and dual data address generators (DAGs) with modulo and bit-reverse addressing for circular buffer management in real-time signal buffering.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core Architecture | Enhanced Harvard with three-bus performance: separate instruction + dual data buses enabling concurrent fetch/execute/data move |
| Instruction Rate | 25 MIPS (40 ns instruction cycle); every instruction executes in one cycle including multi-function ops |
| On-Chip Memory | 2K × 16-bit RAM program memory + 1K × 16-bit RAM data memory; supports boot loading and runtime code/data storage |
| Host Interface Port | 16-bit asynchronous parallel HIP with six 16-bit HDR registers, two status registers (HSR6/7), and configurable strobe/addressing modes |
| Serial Interfaces | Dual synchronous serial ports (SPORT0/SPORT1); SPORT0 supports multichannel TDM (24/32-word), both support A-law/μ-law companding per G.711 |
| Interrupt System | Three external IRQ pins (edge/level-configurable) plus internal sources (timer, SPORTs, HIP); eight vectored interrupt vectors with nested priority handling |
| Supply & Temp | 5 V ± 5% supply; operates across industrial temperature range (–40°C to +85°C) in BG-grade package |
Pinout & Package
ADSP-2111BG-80 is housed in a 100-pin ceramic pin-grid array (PGA) package with 1.27 mm pitch, designed for high-reliability industrial applications and compatible with standard PGA socketing and thermal management solutions.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| BMODE | Boot Mode Select | Configures boot source: low = host interface port; high = external EPROM; determines initial memory mapping path |
| HMD0, HMD1, HSIZE | Host Interface Configuration | Set HIP bus width (8/16-bit), strobe type (separate RW vs. R/W+DSTB), and address/data bus topology (multiplexed vs. discrete) |
| HRD, HWR | Host Read/Write Strobes | Asynchronous active-low signals controlling data transfer direction and timing between host and HIP registers |
| HADR[2:0] | Host Address Lines | 3-bit address selects among six HIP data registers (HDR0–HDR5) and two status registers (HSR6/HSR7) |
| HDATA[15:0] | Host Data Bus | 16-bit bidirectional data path for reading/writing HIP registers; latched by HRD/HWR edges |
| IRQ0–IRQ2 | External Interrupt Inputs | Programmable edge- or level-sensitive inputs; IRQ2 is dedicated; IRQ0/IRQ1 share pins with SPORT1 functions |
| CLKIN | System Clock Input | Accepts TTL-compatible clock or crystal; drives internal PLL-equivalent timing circuitry for 25 MHz core operation |
Key Features
| Feature | Design Value |
|---|---|
| Host Interface Port (HIP) | Enables direct memory-mapped communication with 68000/80C51/ISA-bus hosts without glue logic or FIFO arbitration |

Equivalent & Alternatives
The following parts are listed as comparable options for similar DSP processor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADSP-2115KS-133 | No host interface port; 1K program RAM; 80-lead PQFP; 133 ns instruction cycle (7.5 MHz) | Lacks HIP-requires external glue logic for host interfacing; lower performance limits real-time audio frame rates | Select when cost-sensitive, host-less embedded control is sufficient and board space favors surface-mount packaging |
| TMS320C542-80 | 16-bit fixed-point DSP; 80 MIPS; 128K words addressable memory; 144-pin LQFP; TI C54x ISA | Higher performance and memory but incompatible instruction set and peripheral register map; requires full software rework | Select only when migrating legacy C54x codebase; not drop-in-no pin or software compatibility with ADSP-2111BG-80 |
Compared with ADSP-2111BG-80, ADSP-2115KS-133 sacrifices host integration and speed for lower cost and smaller footprint, while TMS320C542-80 offers higher throughput but demands complete firmware redesign and PCB layout revision due to architectural divergence.

FAQ
What is the maximum operating frequency of the ADSP-2111BG-80?
The ADSP-2111BG-80 operates at a maximum instruction rate of 25 MIPS with a 40 ns instruction cycle time. This corresponds to a 25 MHz system clock input (CLKIN). The "80" suffix denotes the 40 ns speed grade, confirmed in Analog Devices' ADSP-2111 datasheet Section "SPECIFICATIONS (ADSP-2111)" and Table I.
Does the ADSP-2111BG-80 support booting from external memory?
Yes, the ADSP-2111BG-80 supports automatic booting from byte-wide external memory (e.g., EPROM) when the BMODE pin is high. It also supports host-initiated booting via the HIP when BMODE is low. Both methods load program memory without external controllers, as detailed in the "Boot Memory Interface" and "Host Interface Port" sections of the datasheet.
What packages are available for the ADSP-2111BG-80?
The ADSP-2111BG-80 is specifically offered in a 100-pin ceramic pin-grid array (PGA) package, designated by the "BG" suffix. The datasheet confirms this in "PIN CONFIGURATIONS" (page 54) and "ORDERING GUIDE" (page 61), listing ADSP-2111BG-80 exclusively under 100-Pin PGA variants-not PLCC, PQFP, or TQFP.
How many serial ports does the ADSP-2111BG-80 include, and what are their capabilities?
The ADSP-2111BG-80 includes two fully independent synchronous serial ports: SPORT0 and SPORT1. SPORT0 supports multichannel TDM (24/32-word), while both ports provide hardware A-law/μ-law companding per CCITT G.711, double-buffered operation, and flexible framing. These features are explicitly documented in the "Serial Ports" section and Table I of the ADSP-2111 datasheet.
Is the ADSP-2111BG-80 pin-compatible with other ADSP-21xx processors?
No, the ADSP-2111BG-80 is not pin-compatible with other ADSP-21xx devices. Its 100-pin PGA footprint differs from the 68-pin PGA (ADSP-2101), 68-lead PLCC, or 80-lead PQFP packages used by family members. Pin definitions-including HIP-specific signals (HMD0/HMD1/HSIZE/HRD/HWR)-are unique to the ADSP-2111 and appear only in its 100-pin configurations per datasheet pages 54–55.
