Product details
Overview
71V65603S150BGG 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 (ZBT) architecture, and pipelined outputs - designed for high-bandwidth memory subsystems in network switches, packet buffers, and real-time DSP systems.
For engineers reviewing the 71V65603S150BGG datasheet, 71V65603S150BGG pinout, 71V65603S150BGG application, or 71V65603S150BGG equivalent, key selection criteria include burst mode support (linear/interleaved), individual byte write control (BW1–BW4), three chip enables for depth expansion, and JEDEC-standard 119-ball BGA (BGG) packaging with industrial temperature support (–40°C to +85°C).
Technical Context
The 71V65603S150BGG implements a fully synchronous, rising-edge-triggered interface with registered address, control, and data paths. Its ZBT™ architecture eliminates dead cycles between read/write transitions via internal burst counter and ADV/LD-controlled address loading or incrementing.
It supports 4-word burst sequences (linear or interleaved via LBO pin), pipelined output registers synchronized to CLK, and asynchronous OE/ZZ controls for output enable and sleep mode - all operating at 3.3V core (VDD) and I/O (VDDQ) supplies with ±5% tolerance.

Pinout & Package
71V65603S150BGG is packaged in a JEDEC-standard 119-ball fine-pitch ball grid array (BGG119), with 1.0 mm pitch, 12 mm × 12 mm body size, and exposed thermal pad. Pin functions are validated per Renesas datasheet revision 6.42 (Nov. 2021).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A17 | Address Inputs | 18-bit synchronous address bus; latched on rising CLK edge when ADV/LD = LOW and chip enabled |
| CLK | System Clock Input | Rising-edge-triggered master timing reference; all synchronous operations referenced to this edge |
| R/W | Read/Write Control | Synchronous command signal determining data direction for current load cycle (2-cycle latency) |
| ADV/LD | Burst Address Control | Loads new external address (LOW) or advances internal burst counter (HIGH); defines burst sequence start point |
| LBO | Burst Order Select | Static input selecting linear (LBO = LOW) or interleaved (LBO = HIGH) 4-word burst addressing |
| BW1–BW4 | Byte Write Enables | Four independent active-low signals enabling 9-bit byte writes; allows partial-word updates without masking |
| CE1, CE2, CE2 | Chip Enables | Three synchronous enables (CE1/CE2 active LOW, CE2 active HIGH); support multi-chip depth expansion with two-cycle deselect |
| OE | Output Enable | Asynchronous control; tri-states outputs when HIGH - can be tied LOW for simplified read operation |
| ZZ | Sleep Mode Input | Asynchronous low-power entry; gates internal CLK and reduces ICC to minimum while retaining data |
| I/O0–I/O31, I/OP1–I/OP4 | Data I/O Bus | 36-bit bidirectional synchronous data path (32 data + 4 parity); registered input/output with pipelined timing |
| VDD, VDDQ, VSS | Power/Ground | VDD = 3.3V core supply; VDDQ = 3.3V I/O supply (separate for noise isolation); VSS = common ground |
Key Features
| Feature | Design Value |
|---|---|
| ZBTTM Zero Bus Turnaround | Eliminates idle cycles between read-write or write-read transitions, increasing effective bus bandwidth by up to 30% in mixed-access patterns |

Equivalent & Alternatives
The following parts are listed as comparable options for similar synchronous SRAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY7C1362KV18 | 512K × 18-bit organization; same 150 MHz speed, but narrower data bus and different burst control (no LBO pin) | Requires two devices for 36-bit width; lacks linear/interleaved burst flexibility - less optimal for wide-bus packet buffers | Select when system uses 18-bit datapath or requires higher density per device over width |
| AS7C33128PFSIG | 32M-bit (1M × 32) async SRAM; no ZBT, no burst, no pipelining - purely asynchronous interface | Higher density but significantly higher access latency (>12 ns); incompatible with zero-turnaround timing requirements | Consider only for non-pipelined legacy designs where bandwidth > latency is acceptable |
Compared with CY7C1362KV18 and AS7C33128PFSIG, the 71V65603S150BGG uniquely delivers 256K × 36-bit width with ZBT™ and programmable burst order - making it the only option that meets both high-throughput and deterministic low-latency requirements in modern packet-processing architectures.

FAQ
What is the memory configuration and total capacity of the 71V65603S150BGG?
The 71V65603S150BGG is configured as 256K × 36 bits, delivering a total capacity of 9,437,184 bits (9.4 Mbit). This organization provides a 36-bit-wide data bus optimized for packet header storage and wide-data-path DSP applications. It does not support 512K × 18-bit mode - that configuration applies to the pin-compatible 71V65803 variant.
Does the 71V65603S150BGG support burst read and write operations?
Yes, the 71V65603S150BGG supports 4-word burst operations in both read and write modes. Burst sequencing is controlled by the LBO pin: LOW selects linear order (A0, A1, A2, A3), HIGH selects interleaved order (A0, A2, A1, A3). The burst counter advances automatically on each CLK edge when ADV/LD = HIGH, eliminating external address generation logic.
What is the function of the three chip enable pins (CE1, CE2, CE2) on the 71V65603S150BGG?
The 71V65603S150BGG uses CE1 and CE2 as active-low enables and CE2 as an active-high enable. All three must be asserted (CE1 = LOW, CE2 = LOW, CE2 = HIGH) to select the device. This triple-enable scheme allows flexible depth expansion across multiple SRAMs using minimal external logic - for example, decoding higher address bits to drive CE2 while tying CE1/CE2 to shared control lines.
Can the 71V65603S150BGG operate in low-power mode, and how is it controlled?
Yes, the 71V65603S150BGG supports low-power sleep mode via the asynchronous ZZ pin. When ZZ is driven HIGH, the internal clock is gated and ICC drops to its minimum value while data retention is guaranteed. No additional sequencing or voltage scaling is required - the device resumes normal operation within one clock cycle after ZZ returns LOW.
Is the 71V65603S150BGG pin-compatible with other members of the 71V65603/71V65803 family?
The 71V65603S150BGG shares identical pinout and timing with other speed grades (e.g., 71V65603S133BGG) and package variants (TQFP, fBGA) of the same density. However, it is not pin-compatible with the 512K × 18-bit 71V65803 - differences in address pin count (A0–A17 vs. A0–A18) and I/O pin mapping prevent direct substitution without PCB redesign.
