Product details
Overview
CY62138FV30LL-45SXI from Cypress Semiconductor is a 2-Mbit (256 K × 8) CMOS static RAM with 45 ns access time, 2.2–3.6 V supply voltage, and ultra-low standby current (1 µA typical). It features dual chip enables (CE1/CE2), automatic power-down on deselect, and operates across –40 °C to +85 °C for industrial and automotive-A applications including portable telecom and battery-powered instrumentation.
For engineers reviewing the CY62138FV30LL-45SXI datasheet, CY62138FV30LL-45SXI pinout, CY62138FV30LL-45SXI application, or CY62138FV30LL-45SXI equivalent, key selection criteria include its MoBL® low-power architecture, dual CE control logic, 36-ball VFBGA package compatibility, and guaranteed 45 ns read/write timing at full industrial temperature range.
Technical Context
The CY62138FV30LL-45SXI implements a synchronous, non-volatile-retentive SRAM core with complementary metal oxide semiconductor (CMOS) process technology optimized for speed–power trade-off. Its dual chip enable (CE1 LOW + CE2 HIGH = active) supports hierarchical memory expansion and selective bank power gating.
It uses address latching via A0–A17 (18-bit), eight bidirectional I/O lines (I/O0–I/O7), and separate OE/WE controls to decouple read and write paths. Data retention is guaranteed down to 1.5 V with ICCDR ≤ 4 µA, enabling backup operation during brown-out conditions.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar SRAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ISSI IS62WV2568BLL-45NLI | Same 256K × 8 organization, 45 ns speed, but single CE input and 32-pin SOIC-only packaging | Lacks dual CE for hierarchical expansion; limited to board-level space-constrained designs without BGA capability | Select when legacy SOIC footprint reuse is mandatory and memory banking is handled externally |
| Renesas R1LV2568ASBG-45PB | Identical 256K × 8, 45 ns, –40 °C to +85 °C, but uses 32-pin TSOP II and has higher standby current (5 µA typical) | Higher ISB reduces battery lifetime in always-on nodes; TSOP II limits board density vs. VFBGA | Choose where thermal dissipation in air-cooled systems outweighs package size constraints |
Compared with IS62WV2568BLL-45NLI and R1LV2568ASBG-45PB, CY62138FV30LL-45SXI delivers superior system-level power efficiency via dual CE–enabled selective bank shutdown and lower 1 µA standby current-critical for energy-harvesting and long-life battery deployments.

FAQ
What is the function of CE1 and CE2 in CY62138FV30LL-45SXI?
CE1 and CE2 implement dual-level chip enable logic: the device activates only when CE1 is LOW and CE2 is HIGH. This allows hierarchical memory mapping-e.g., CE2 can serve as a bank select while CE1 acts as per-chip enable-enabling up to four 256K banks using two address lines without external decoding logic.
Does CY62138FV30LL-45SXI support data retention during power loss?
Yes. When VCC drops to ≥1.5 V and CE1 is HIGH or CE2 is LOW, the device enters data retention mode with ICCDR ≤ 4 µA. Memory contents remain valid for ≥10 years at +25 °C, verified per JEDEC JESD22-A117 standard, making it suitable for brown-out recovery in critical control systems.
Can CY62138FV30LL-45SXI be used with a 1.8 V microcontroller interface?
No. The device requires VCC between 2.2 V and 3.6 V and specifies VIH(min) = 1.8 V only when VCC is 2.2–2.7 V. Driving inputs from a 1.8 V MCU violates VIH requirements and risks unreliable operation; level-shifting or supply rail matching is mandatory.
Is the 36-ball VFBGA package of CY62138FV30LL-45SXI compatible with standard reflow profiles?
Yes. The Pb-free 36-ball VFBGA complies with IPC/JEDEC J-STD-020D, supporting peak reflow temperatures up to 260 °C for ≤30 seconds. Thermal resistance θJA = 38.49 °C/W (still air) confirms suitability for compact, thermally isolated PCB layouts without forced cooling.
