Product details
Overview
71V35761SA183BGGI8 from IDT is a 128K × 36-bit, 3.3V synchronous SRAM with pipelined outputs, burst counter, and single-cycle deselect. It operates at 183MHz (3.3ns clock access time), supports linear/interleaved burst modes via LBO input, and features JTAG boundary scan (IEEE 1149.1) for testability in high-speed networking and embedded control systems.
For engineers reviewing the 71V35761SA183BGGI8 datasheet, 71V35761SA183BGGI8 pinout, 71V35761SA183BGGI8 application, or 71V35761SA183BGGI8 equivalent, this page delivers verified timing parameters, JEDEC-standard BGA-119 package mapping, synchronous burst read/write behavior, sleep mode (ZZ) power management, and JTAG interface configuration - all confirmed for the SA variant with industrial temperature range (–40°C to +85°C).
Technical Context
The 71V35761SA183BGGI8 implements a synchronous, clock-driven architecture with registered address, data, and control inputs. Its internal burst address counter generates four sequential 36-bit words per address, with output pipelining delivering first data on the second rising CLK edge after ADSP/ADSC assertion.
Burst order is selected statically via LBO (LOW = linear, HIGH = interleaved); write operations support global (GW) or byte-level (BW1–BW4 + BWE) control with self-timed completion. JTAG TAP controller (TMS/TDI/TCK/TRST/TDO) is integrated and functional in the SA version, compliant with IEEE 1149.1.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Organization | 128K × 36-bit (4.608 Mbit), enabling 36-bit wide data paths for RISC processors and network packet buffers. |
| Clock Frequency / Access Time | 183 MHz / 3.3 ns - guarantees deterministic read latency in real-time control loops and switch fabric interfaces. |
| Supply Voltages | VDD = 3.3 V ±5% (core), VDDQ = 3.3 V ±5% (I/O) - eliminates level-shifting requirements in 3.3V system designs. |
| Burst Mode Control | LBO pin selects linear or interleaved 4-word burst sequence - critical for cache line alignment in CPU coherency protocols. |
| Power Management | ZZ input enables full sleep mode (IZZ ≤ 35 mA) with data retention - reduces standby power in always-on telecom modules. |
| JTAG Support | IEEE 1149.1-compliant boundary scan (TMS/TDI/TCK/TRST/TDO) - enables in-system test and debug without physical probe access. |
| Operating Temperature | –40°C to +85°C (industrial grade) - validated for deployment in base station RF units and industrial PLC backplanes. |
Pinout & Package
Packaged in a JEDEC-standard 119-ball fine-pitch BGA (BGG), footprint code BGGI8 denotes industrial-grade, lead-free, RoHS-compliant assembly with 0.8 mm ball pitch and 13 mm × 13 mm body size.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A17 | Address Inputs | Synchronous 18-bit address bus; A0–A1 select internal 9-bit byte within 36-bit word for burst sequencing. |
| CLK | System Clock Input | Rising-edge-triggered master timing reference; all registers (address, data, control) sample on CLK rise. |
| ADSP / ADSC | Address Status Inputs | ADSP (processor) or ADSC (cache controller) asserts LOW to latch address and initiate burst cycle - enables dual-bus arbitration. |
| ADV | Burst Address Advance | LOW enables internal counter increment; HIGH suspends burst - allows dynamic burst termination during cache miss handling. |
| GW / BWE / BW1–BW4 | Write Control Inputs | GW writes all 4 bytes; BWE enables byte-write mode; BW1–BW4 select individual 9-bit bytes - supports partial-word updates without read-modify-write. |
| I/O0–I/O31, I/OP1–I/OP4 | Data I/O (36-bit) | Registered bidirectional bus: outputs pipelined (1-cycle delay), inputs captured on CLK rise - ensures setup/hold compliance at 183 MHz. |
| ZZ | Sleep Mode Enable | Asynchronous HIGH disables internal clock and reduces current to ≤35 mA while retaining memory contents - critical for low-power wake-on-event designs. |
| TMS/TDI/TCK/TRST/TDO | JTAG Test Interface | Full 5-pin IEEE 1149.1 TAP controller; TRST optional asynchronous reset - supports automated board test and firmware validation. |
Key Features
| Feature | Design Value |
|---|---|
| Pipelined Burst Outputs | First data appears on second CLK edge; subsequent words align to consecutive edges - eliminates wait states in high-throughput DMA transfers. |
| Single-Cycle Deselect | Chip deactivation completes within one clock cycle after CE/CS deassertion - prevents bus contention during rapid context switching. |
| Self-Timed Write Cycle | Internal timing logic finalizes write completion without external strobe - simplifies controller design and improves write reliability across voltage/temperature variation. |
| Linear/Interleaved Burst Order | LBO pin configures burst address sequence to match CPU cache line layout (e.g., Pentium vs. PowerPC) - avoids software workarounds for memory mapping. |
| 3.3V Core & I/O Compatibility | Dual 3.3V supplies (VDD/VDDQ) with VIH/VIL thresholds referenced separately - ensures noise margin in mixed-signal FPGA/SOC interfacing. |
Applications
| Network Packet Buffering | CPU Cache Coherency |

Equivalent & Alternatives
The following parts are listed as comparable options for similar synchronous SRAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY7C1371DV33-183BZXI | 128K × 36, 183 MHz, 3.3V, no JTAG; uses different burst control (MODE pin vs. LBO); BGA-119 but non-identical pinout. | Lacks IEEE 1149.1 test interface; requires external boundary scan for production test coverage. | Select when JTAG is unnecessary and legacy Cypress toolchain compatibility is required. |
| AS7C33128P33A-183BIN | 128K × 36, 183 MHz, 3.3V, no sleep mode (ZZ) or burst suspend (ADV); TQFP-only packaging. | No ZZ power-down or ADV-controlled burst suspension - limits use in ultra-low-power or adaptive bandwidth systems. | Select for cost-sensitive, non-industrial applications where TQFP assembly is preferred and power management is secondary. |
Compared with CY7C1371DV33-183BZXI and AS7C33128P33A-183BIN, the 71V35761SA183BGGI8 uniquely integrates JTAG testability and programmable burst suspension (ADV) - enabling both production test automation and dynamic bandwidth adaptation in mission-critical embedded systems.

FAQ
What is the maximum operating frequency and corresponding access time for the 71V35761SA183BGGI8?
The 71V35761SA183BGGI8 is rated for 183 MHz operation with a guaranteed clock access time of 3.3 ns under industrial temperature conditions (–40°C to +85°C). This specification is validated across VDD and VDDQ at 3.3 V ±5%, and applies to both read and write cycles with proper setup/hold timing margins.
Does the 71V35761SA183BGGI8 support JTAG boundary scan, and which pins are used?
Yes, the 71V35761SA183BGGI8 (SA variant) includes full IEEE 1149.1-compliant JTAG boundary scan. Pins TMS, TDI, TCK, TDO, and optional TRST are assigned on the BGG119 package (U1–U6 positions), with internal pull-ups on TMS/TDI/TCK/TRST and internal pull-down on ZZ.
How does burst mode operate in the 71V35761SA183BGGI8, and what controls the sequence order?
Burst mode in the 71V35761SA183BGGI8 delivers four 36-bit words per address using an internal binary counter. The LBO pin selects linear (LBO = LOW) or interleaved (LBO = HIGH) sequence order - matching CPU cache line layouts without software intervention.
What is the function of the ADV pin in the 71V35761SA183BGGI8, and how does it affect burst operation?
The ADV pin in the 71V35761SA183BGGI8 controls burst address advancement: ADV = LOW increments the internal counter for normal burst progression; ADV = HIGH suspends counter advance, holding the current address for repeated access - useful for cache line fills or diagnostic reads.
What power-saving modes does the 71V35761SA183BGGI8 support, and what is the typical current draw in each?
The 71V35761SA183BGGI8 supports CMOS standby (ISB1 ≤ 35 mA), clock-running standby (ISB2 ≤ 130 mA), and full sleep mode (IZZ ≤ 35 mA) activated by the ZZ pin. All modes retain data; sleep mode gates the internal clock and minimizes dynamic power consumption.
