Product details
Overview
71V016SA12BF8 from Renesas Electronics is a 3.3V, 1-Megabit (64K × 16) high-speed CMOS static RAM with 12 ns access time, industrial-grade temperature range (–40°C to +85°C), LVTTL-compatible I/O, and byte-enable control - used in real-time embedded controllers requiring deterministic memory access without refresh overhead.
For engineers reviewing the 71V016SA12BF8 datasheet, 71V016SA12BF8 pinout, 71V016SA12BF8 application, or 71V016SA12BF8 equivalent, this page delivers verified timing specs, FBGA-48 package mapping, byte-select functionality, standby current (ISB = 40 mA), and industrial-temperature validation - all critical for legacy system replacement and avionics data buffering.
Technical Context
The 71V016SA12BF8 implements fully static asynchronous circuitry with no clocks or refresh required. Its dual-byte enable (BHE/BLE) supports independent 8-bit read/write operations on upper and lower data bytes, while the single 3.3V supply simplifies power rail design.
It features three distinct enable paths: chip select (CS), output enable (OE), and byte enables (BHE/BLE), each with defined timing windows (tCLZ = 4 ns, tOE = 6 ns, tBE = 6 ns). All inputs and outputs are LVTTL-compatible, ensuring interoperability with legacy 3.3V logic families.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Size | 64K × 16-bit (1,048,576 bits) - provides word-aligned storage for 16-bit microcontrollers and DSPs. |
| Access Time | 12 ns max - guarantees sub-83 MHz bus operation with margin for PCB trace delays. |
| Supply Voltage | 3.15 V to 3.6 V - compatible with standard 3.3V LVTTL systems; no level-shifting needed. |
| Operating Temperature | –40°C to +85°C - qualified for industrial and extended-temperature embedded applications. |
| Standby Current | 40 mA max (ISB) - enables low-power hold mode during processor sleep without data loss. |
| I/O Interface | LVTTL-compatible bidirectional I/O - directly interfaces with FPGA I/O banks and MCU data buses. |
| Package | 48-ball FBGA (7 mm × 7 mm, BFG48) - compact footprint suitable for space-constrained PCB layouts. |
Pinout & Package
71V016SA12BF8 is housed in a JEDEC-standard 48-ball plastic FBGA (BFG48) package with 0.8 mm ball pitch and bottom-side thermal pad. The package supports automated optical inspection and reflow soldering per IPC-J-STD-020.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A15 | Address Inputs | 16-bit address bus for full 64K-word addressing; no internal multiplexing. |
| I/O0–I/O7 | Low-Byte Data I/O | Bidirectional 8-bit data path enabled only when BLE = L; isolated from high byte during partial writes. |
| I/O8–I/O15 | High-Byte Data I/O | Bidirectional 8-bit data path enabled only when BHE = L; allows independent 16-bit or byte-level transfers. |
| CS | Chip Select | Active-low global enable; device enters standby (ISB1 = 10 mA) when high. |
| OE | Output Enable | Active-low control for output drivers; tOE = 6 ns ensures fast read response after CS assertion. |
| WE | Write Enable | Active-low write strobe; tWP = 8 ns minimum pulse width defines shortest write cycle. |
| BHE | High-Byte Enable | Active-low control for I/O8–I/O15; enables high-byte reads/writes without affecting low byte. |
| BLE | Low-Byte Enable | Active-low control for I/O0–I/O7; permits byte-granular memory updates in mixed-data-width systems. |
| VDD | Power Supply | 3.3V primary supply; two dedicated VDD balls reduce IR drop and switching noise. |
| VSS | Ground | Ground reference; four VSS balls provide low-inductance return paths for I/O and core logic. |
Key Features
| Feature | Design Value |
|---|---|
| Byte-select architecture | Independent BHE/BLE pins enable true 8-bit partial writes - avoids read-modify-write cycles in 16-bit systems. |
| Zero-refresh static operation | Fully asynchronous design eliminates clock tree, refresh controller, and associated timing constraints. |
| Industrial temperature qualification | –40°C to +85°C operation validated across speed grade and package - suitable for motor drives and railway control units. |
| Low-Z output enable timing | tOLZ = 0 ns ensures immediate data bus availability after OE assertion - critical for burst-mode DMA transfers. |
| Green packaging option | Halogen-free, RoHS-compliant BFG48 package meets IPC-1752A material declaration requirements. |
Applications
| Industrial PLC Memory Buffer | Avionics Data Logger |
|---|---|

IC Role / Device Role / Timing Role: Dual-port-capable SRAM (via time-multiplexed CS/OE/WE) serving as line buffer and frame store in ASIC-based imaging pipelines. Use Value: Supports simultaneous read (DMA to encoder) and write (ADC interface) via byte-enable isolation - preventing bus contention without external logic. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed static RAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY62167EV30LL-45ZSXI | 45 ns access time; 32K × 16 organization; 2.2–3.6 V supply; 48-TSOP package | Lower density and slower speed; suited for cost-sensitive, non-real-time buffering | Select when 12 ns timing is unnecessary and TSOP layout compatibility is prioritized over FBGA miniaturization. |
| AS6C1008-12TIN | 12 ns access; 64K × 16; 3.3 V only; 44-pin SOJ package; ISB = 30 mA typical | Same speed and density but SOJ packaging limits board density and thermal performance | Choose for through-hole prototyping or legacy SOJ socket reuse where FBGA rework capability is unavailable. |
Compared with CY62167EV30LL-45ZSXI and AS6C1008-12TIN, the 71V016SA12BF8 uniquely combines industrial-temperature FBGA packaging, byte-select precision, and 12 ns access in a single 3.3V supply - making it optimal for new designs demanding compactness, thermal robustness, and deterministic timing.

FAQ
What is the maximum operating frequency supported by the 71V016SA12BF8?
The 71V016SA12BF8 does not operate on a clock; it is an asynchronous SRAM. Its 12 ns access time supports effective bus frequencies up to approximately 83 MHz (1/12 ns) in systems with zero wait-state timing. Actual achievable bandwidth depends on system-level timing margins, PCB layout, and controller interface capabilities - but the 71V016SA12BF8 itself imposes no clock requirement or frequency ceiling.
Does the 71V016SA12BF8 require external refresh circuitry?
No, the 71V016SA12BF8 is a fully static RAM and requires no refresh circuitry or periodic access to retain data. Its CMOS latch-based memory cells maintain state indefinitely as long as VDD remains within specification (3.15 V to 3.6 V) and ambient temperature stays within –40°C to +85°C. This eliminates refresh overhead and timing uncertainty inherent in DRAM - a key advantage of the 71V016SA12BF8 in real-time systems.
Can the 71V016SA12BF8 be used with 5V-tolerant microcontrollers?
No - the 71V016SA12BF8 is strictly a 3.3V LVTTL device with VIH(max) = VDD + 0.3 V and VIL(min) = –0.3 V. It is not 5V-tolerant. Direct connection to 5V logic will exceed absolute maximum input voltage ratings and risk permanent damage. Interfacing with 5V systems requires level translation, such as TI SN74AVC4T245 or similar dual-supply translators, to protect the 71V016SA12BF8 inputs and ensure valid signal thresholds.
What is the function of the BHE and BLE pins on the 71V016SA12BF8?
The BHE (High-Byte Enable) and BLE (Low-Byte Enable) pins on the 71V016SA12BF8 independently control access to the upper (I/O8–I/O15) and lower (I/O0–I/O7) data bytes. When BHE = L and BLE = H, only the high byte is active; when BLE = L and BHE = H, only the low byte is active; when both are L, full 16-bit word access occurs. This enables precise byte-granular writes without read-modify-write sequences - a core functional feature of the 71V016SA12BF8.
Is the 71V016SA12BF8 pin-compatible with other speed grades in the same package?
Yes - all 71V016SAxxBF8 variants (e.g., 71V016SA10BF8, 71V016SA15BF8) share identical BFG48 pinout, ball assignment, and electrical interface. Speed grade differences affect only timing parameters (e.g., tAA, tRC) and AC characteristics; DC specifications, pin functions, and package dimensions remain unchanged. This allows drop-in replacement during design optimization or cost/performance trade-offs - provided system timing margins accommodate the selected speed grade's specifications.
