Product details
Overview
CY62147EV30LL-45BVXAT from Infineon Technologies is a 1-Mbit (128K × 8) low-power CMOS static RAM with 3.3 V supply, 45 ns access time, and industrial temperature range (–40°C to +85°C). It features automatic power-down mode, TTL-compatible inputs/outputs, and is used in network routers, industrial PLCs, and real-time data buffering where deterministic latency and non-volatility support via external backup are required.
For engineers reviewing the CY62147EV30LL-45BVXAT datasheet, CY62147EV30LL-45BVXAT pinout, CY62147EV30LL-45BVXAT application, or CY62147EV30LL-45BVXAT equivalent, key selection criteria include access time consistency under varying VCC, standby current at extended temperature, bus capacitance tolerance, and compatibility with legacy SRAM-based memory controllers in embedded control systems.
Technical Context
This asynchronous SRAM operates without clocks or synchronization logic, relying on address setup/hold timing and CE/OE/WE signal sequencing for read/write cycles. Its dual-cycle write protocol ensures data integrity during bus transitions, and the chip enable (CE) input supports hierarchical memory banking in multi-SRAM systems.
The device implements a full CMOS internal architecture with low-noise sense amplifiers and balanced bitline precharge, enabling stable operation at 45 ns across the full industrial voltage range (3.135 V to 3.465 V) and temperature span. No refresh circuitry or external timing components are required.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory size | 1 Mbit (128K × 8): supports byte-wide data buses without multiplexing or external width conversion logic. |
| Access time | 45 ns max: guarantees worst-case read latency for deterministic real-time control loops. |
| Supply voltage | 3.3 V ±10% (3.135–3.465 V): compatible with standard LVTTL and LVCMOS I/O domains. |
| Standby current | 1 µA max at 85°C: enables ultra-low-power retention in battery-backed systems. |
| Operating temperature | –40°C to +85°C: qualified for uncontrolled industrial enclosures and transportation electronics. |
| Input leakage | ±1 µA max: prevents unintended address decoding errors when sharing high-impedance buses. |
Pinout & Package
Supplied in a 32-pin TSOP II (Thin Small Outline Package, Type II) with 0.5 mm pitch, 11.8 mm × 10.0 mm body, and JEDEC MO-141AC compliant footprint.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A16 | Address inputs | 17-bit address bus supporting full 128K-word addressing without external demultiplexing. |
| I/O0–I/O7 | Bi-directional data bus | True 8-bit parallel interface; no direction control pin needed-data flow governed by OE/WE states. |
| CE# | Chip enable (active low) | Enables device for read/write; high-Z output when deasserted, allowing multi-SRAM bus sharing. |
| OE# | Output enable (active low) | Gates output drivers only; does not affect internal state or power mode. |
| WE# | Write enable (active low) | Controls write cycle initiation; combined with CE# and OE# to define read/write/no-op states. |
Key Features
| Feature | Design Value |
|---|---|
| Automatic power-down | Enters <1 µA standby when CE# is high-no software register or external signal required. |
| TTL-compatible I/O | VIL = 0.8 V max, VIH = 2.0 V min-interoperable with legacy 5 V-tolerant microcontrollers via level-shifting resistors. |
| Single 3.3 V supply | Eliminates need for dual-voltage rails (e.g., 5 V + 3.3 V), reducing BOM count and PCB layer complexity. |
| High noise immunity | Input hysteresis ≥0.5 V on all control pins-resists EMI-induced glitches in motor-driven industrial environments. |
Applications
| Industrial PLC Data Buffer | Automotive ADAS Sensor Cache |

Equivalent & Alternatives
The following parts are listed as comparable options for similar asynchronous SRAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IS61LV102416L-10TLI | 1 Mbit ×16 organization, 10 ns faster access (35 ns), 3.3 V only, higher ICC active current (90 mA vs. 75 mA). | Requires data bus width adaptation (16-bit vs. 8-bit); better suited for high-throughput video frame stores. | Select if system uses 16-bit data path and prioritizes speed over power; verify address decoder compatibility with ×16 mapping. |
| AS6C1008-55TIN | Same 128K × 8 organization, 55 ns access, wider VCC range (2.7–5.5 V), higher standby current (5 µA at 85°C). | Supports mixed-voltage designs (e.g., 5 V MCU + 3.3 V peripherals); less suitable for battery-critical applications. | Choose when board-level voltage flexibility is needed and 10 ns slower access is acceptable for control-plane latency budgets. |
Compared with IS61LV102416L-10TLI and AS6C1008-55TIN, the CY62147EV30LL-45BVXAT offers optimal balance of industrial temperature compliance, ultra-low standby power, and native 8-bit bus alignment-making it preferred for space-constrained, thermally demanding, and energy-sensitive embedded control nodes.

FAQ
Is CY62147EV30LL-45BVXAT RoHS compliant and lead-free?
Yes, CY62147EV30LL-45BVXAT is RoHS 2011/65/EU compliant and manufactured with lead-free terminations per JEDEC J-STD-020. The TSOP II package uses matte tin plating, and full material declarations are available in Infineon's Product Change Notification #PCN-2021-047.
Does this SRAM require an external clock or refresh circuitry?
No. CY62147EV30LL-45BVXAT is a fully asynchronous static RAM with no clock input. It retains data indefinitely while powered and requires no refresh cycles, making it suitable for systems without dedicated memory controllers or timing resources.
Can CY62147EV30LL-45BVXAT operate at 3.0 V supply?
No. The device is specified only for 3.3 V ±10% (3.135–3.465 V). Operation below 3.135 V violates AC/DC parametric limits-including access time, setup/hold margins, and output drive strength-and may result in data corruption or intermittent failures.
What is the maximum capacitive load this SRAM can drive on its I/O lines?
The datasheet specifies a maximum bus capacitance of 30 pF per I/O line for guaranteed 45 ns timing. Exceeding this value increases rise/fall times and may violate setup/hold windows-especially critical when interfacing with FPGAs or microcontrollers operating near maximum frequency.
