Product details
Overview
71V124SA12YGI8 from Renesas Electronics is a 128K × 8-bit, 1 Mbit high-speed CMOS static RAM with 12 ns access time, single 3.3 V supply operation, LVTTL-compatible I/O, and industrial temperature range (–40°C to +85°C). It features JEDEC center-power/ground pinout for noise reduction and is used in real-time control buffers, network packet memory, and FPGA configuration storage.
For engineers reviewing the 71V124SA12YGI8 datasheet, 71V124SA12YGI8 pinout, 71V124SA12YGI8 application, or 71V124SA12YGI8 equivalent, key selection criteria include tAA ≤ 12 ns read access, tWC = 12 ns write cycle, CS/OE dual-control timing, SOJ-32 (400-mil) package compatibility, and industrial-grade reliability for embedded systems requiring deterministic memory latency.
Technical Context
The 71V124SA12YGI8 implements fully static asynchronous circuitry-no clocks or refresh required-and uses bidirectional LVTTL-compatible I/O lines with independent Chip Select (CS) and Output Enable (OE) controls. Its JEDEC-standard center-power/ground pinout minimizes simultaneous switching noise across the 32-pin SOJ footprint.
Operation relies on address-valid timing constraints (tAS = 0 ns), fast output enable response (tOE ≤ 6 ns), and low-impedance data bus drive (VOL ≤ 0.4 V at 8 mA). Standby current is minimized via CS-driven deselection (ISB1 = 10 µA typical), supporting low-power hold modes without external power gating.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Organization | 128K × 8-bit (1,048,576-bit total); supports byte-wide data transfers without external multiplexing |
| Access Time (tAA) | 12 ns max; guarantees deterministic read latency for real-time interrupt handlers and DMA burst reads |
| Supply Voltage | 3.15–3.6 V; compatible with standard 3.3 V LVTTL logic rails and tolerant of ±5% regulation variation |

| OE | Output Enable | Active-low control for output drivers; allows read data gating without deselecting chip |
| WE | Write Enable | Active-low write strobe; defines write cycle boundaries independently of CS timing |
| VDD | Power Supply | 3.3 V core and I/O supply; pin 24 (center-right) reduces power distribution inductance |
| GND | Ground Reference | Signal and power return; pin 13 (center-left) pairs with VDD to minimize loop area |

IC Role / Device Role / Timing Role: Low-jitter, deterministic-access memory for pixel data streaming into DMA controllers. Use Value: 12 ns tAA and 12 ns tWC support sustained 83 MB/s throughput-sufficient for 1024×768 @ 60 fps raw video. |
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 |
|---|---|---|---|
| CY62128EV30LL-45ZSXI | 45 ns access time; 5 V tolerant I/O; 32-pin TSOP-II; higher ICC (150 mA) | Targeted at legacy 5 V systems; not suitable for 3.3 V LVTTL-only designs | Select only if voltage compatibility with older peripherals is required and 45 ns latency is acceptable |
| AS6C1008-12TIN | 12 ns access; 3.3 V only; 32-pin TSOP-II; lower ISB1 (5 µA); no center-power pinout | Lacks JEDEC noise-reduction layout; requires additional decoupling for EMI-sensitive medical equipment | Prefer where board space favors TSOP over SOJ and ultra-low standby current outweighs noise immunity needs |
Compared with CY62128EV30LL-45ZSXI and AS6C1008-12TIN, the 71V124SA12YGI8 uniquely combines industrial temperature rating, center-power SOJ packaging, and 12 ns performance in a single 3.3 V LVTTL solution-making it optimal for new designs prioritizing noise resilience and drop-in replacement of legacy IDT SRAMs.
