Product details
Overview
71V65803S100BGG from Renesas Electronics is a 3.3V synchronous ZBT™ SRAM with 256K × 36-bit (9,437,184-bit) organization, 150 MHz clock speed, 3.8 ns clock-to-data access, zero bus turnaround architecture, and pipelined outputs. It operates across industrial temperature (–40°C to +85°C), supports 4-word burst (linear/interleaved), and features individual byte write control for high-bandwidth networking and packet buffering applications.
For engineers reviewing the 71V65803S100BGG datasheet, 71V65803S100BGG pinout, 71V65803S100BGG application, or 71V65803S100BGG equivalent, key selection criteria include ZBT™ timing compliance, TQFP-100 package compatibility, 3.3V I/O and core supply requirements, burst counter behavior under ADV/LD control, and industrial-grade thermal performance.
Technical Context
The 71V65803S100BGG implements a fully synchronous, positive-edge-triggered interface with registered address, data, and control inputs. Its ZBT™ architecture eliminates dead cycles between read/write transitions via internal burst counter synchronization and pipelined output registers.
It uses three chip enables (CE1, CE2, CE2) with mixed polarity for flexible depth expansion, supports asynchronous OE and ZZ for output control and sleep mode, and relies on LBO to statically select linear or interleaved burst order-no dynamic reconfiguration during operation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Organization | 256K × 36-bit (9.4 Mbit); supports high-density data buffering without external width expansion |
| Max Clock Frequency | 150 MHz; enables 6.67 ns cycle time for real-time packet processing in telecom line cards |
| Clock-to-Data Access | 3.8 ns; guarantees deterministic read latency two cycles after address load for pipeline-synchronized systems |
| Supply Voltages | VDD = 3.3 V ±5%, VDDQ = 3.3 V ±5%; separate core/I/O rails simplify power integrity design |
| Operating Temperature | –40°C to +85°C; qualified for industrial embedded systems including base station control planes |
| Burst Capability | 4-word burst (linear or interleaved); reduces address bus traffic by 75% per burst sequence |
| Byte Write Control | BW1–BW4 active-low enables; allows partial 9-bit writes without masking logic or extra glue logic |
Pinout & Package
Packaged in JEDEC-standard 100-pin thin quad flatpack (TQFP), 14 mm × 20 mm footprint, lead-free and RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CLK | Clock input | Positive-edge-triggered master timing reference for all synchronous registers |
| A0–A17 | Address inputs | 18-bit address bus supporting 256K depth; latched on rising CLK edge with ADV/LD low |
| R/W | Read/Write control | Synchronous signal defining cycle type; determines data direction two cycles later |
| ADV/LD | Burst advance / address load | High = increment internal burst counter; low = load new external address into register |
| LBO | Burst order select | Static input: low = linear burst (0,1,2,3), high = interleaved (0,2,1,3) |
| BW1–BW4 | Byte write enables | Four independent active-low signals controlling 9-bit subwords (I/O[0:7]+I/OP1 through I/O[24:31]+I/OP4) |
| CE1, CE2, CE2 | Chip enables | Three enables with CE2 inverted; any false condition initiates two-cycle deselect and tri-state |
| OE | Output enable | Asynchronous; ties low for full read enable-no timing-critical OE management needed |
| ZZ | Sleep mode | Asynchronous; gates internal clock and reduces power to retention level while preserving data |
| I/O0–I/O31, I/OP1–I/OP4 | Data I/O | 36-bit bidirectional bus with registered input/output paths; supports concurrent burst reads/writes |
Key Features
| Feature | Design Value |
|---|---|
| ZBT™ Zero Bus Turnaround | Eliminates idle cycles between consecutive read/write operations-enables continuous 150 MHz bus utilization |
| Internally synchronized OE | Removes need for precise OE timing control; outputs remain stable even if OE is statically asserted |
| Single R/W pin | Reduces control bus complexity versus separate RD/WR signals-simplifies FPGA or ASIC interface logic |
| 4-word burst counter | Generates sequential addresses internally-cuts external address generation logic and routing congestion |
| Three chip enables | Supports seamless memory depth expansion across multiple devices without additional decode logic |

Equivalent & Alternatives
The following parts are listed as comparable options for similar synchronous SRAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY7C1362BV33-133AXC | 133 MHz max frequency, 4.5 ns tCD, 512K × 18 organization, same TQFP-100 package | Lower bandwidth; suited for cost-sensitive designs where 150 MHz is not required | Select when system clock is ≤133 MHz and width expansion (×18 → ×36) is acceptable |
| AS7C3256A-15JC | 15 ns async access, no ZBT™ or burst counter, 32K × 8 organization, SOJ-32 package | Asynchronous interface; requires external control logic for burst and turnaround management | Choose only for legacy designs lacking synchronous clock infrastructure or burst requirements |
Compared with CY7C1362BV33-133AXC and AS7C3256A-15JC, the 71V65803S100BGG delivers higher throughput via ZBT™ and 4-word burst, supports wider 36-bit data paths natively, and maintains industrial temperature operation-making it optimal for next-generation telecom and industrial real-time buffers.

FAQ
What is the memory configuration and total capacity of the 71V65803S100BGG?
The 71V65803S100BGG is configured as 256K × 36 bits, delivering a total capacity of 9,437,184 bits (9.4 Mbit). This organization provides native 36-bit data width-ideal for systems aligned to 32-bit+ buses with parity or ECC overhead-eliminating the need for external width expansion or data multiplexing logic.
Does the 71V65803S100BGG support both linear and interleaved burst modes?
Yes, the 71V65803S100BGG supports both linear and interleaved 4-word burst sequences via the LBO (Linear Burst Order) pin. When LBO is low, the burst order is linear (e.g., A0, A1, A2, A3); when high, it is interleaved (e.g., A0, A2, A1, A3). This static selection enables optimization for sequential streaming or cache-line-aligned access patterns without runtime reconfiguration.
What is the role of the ZZ pin on the 71V65803S100BGG?
The ZZ pin on the 71V65803S100BGG is an asynchronous sleep mode input. When driven high, it internally gates the clock and places the device in its lowest-power state while guaranteeing data retention. This feature is critical for power-constrained industrial applications where periodic deep-sleep operation is required without data loss or external refresh circuitry.
How does the ZBT™ architecture of the 71V65803S100BGG improve system performance?
The ZBT™ (Zero Bus Turnaround) architecture of the 71V65803S100BGG eliminates dead cycles between consecutive read and write operations. By synchronizing internal burst counters and pipelining outputs, it enables immediate transition from write to read (or vice versa) without bus idle time-achieving sustained 150 MHz utilization in high-throughput packet buffering and telecom applications.
What package type and pin count does the 71V65803S100BGG use?
The 71V65803S100BGG uses a JEDEC-standard 100-pin thin quad flatpack (TQFP) package, measuring 14 mm × 20 mm. This surface-mount package supports automated assembly, offers robust thermal performance for industrial environments, and is compatible with standard PCB layout practices for high-speed synchronous memory interfaces.
