Product details
Overview
CY62128EV30LL-45SXI from Cypress Semiconductor is a 1-Mbit (128K × 8) CMOS static RAM with 45 ns access time, 2.2–3.6 V supply voltage, and industrial temperature range (–40 °C to +85 °C). It features dual chip enables (CE1/CE2), ultra-low standby current (1 µA typical), and automatic power-down when deselected - optimized for battery-powered portable electronics including cellular handsets and handheld instrumentation.
For engineers reviewing the CY62128EV30LL-45SXI datasheet, CY62128EV30LL-45SXI pinout, CY62128EV30LL-45SXI application, or CY62128EV30LL-45SXI equivalent, key selection criteria include its MoBL® low-power architecture, 32-pin STSOP package compatibility, CE/OE/WE control logic timing, and data retention capability down to 1.5 V.
Technical Context
The CY62128EV30LL-45SXI implements a fully static 128K × 8 memory array with complementary metal oxide semiconductor (CMOS) process technology. Its dual chip enable (CE1 HIGH / CE2 LOW = deselected) and output enable (OE) control allow flexible memory expansion and precise bus isolation.
It supports three operational modes: active read (CE1 LOW, CE2 HIGH, OE LOW, WE HIGH), active write (CE1 LOW, CE2 HIGH, WE LOW), and automatic power-down (CE1 HIGH or CE2 LOW), reducing ICC by >99% in standby. Data retention remains valid at VCC ≥ 1.5 V with ICCDR ≤ 3 µA.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Organization | 128K × 8 bits - provides 1 Mbit of non-volatile-accessible SRAM with byte-wide I/O interface |
| Access Time | 45 ns - guarantees maximum read latency under industrial conditions (VCC = 2.2–3.6 V, TA = –40 °C to +85 °C) |
| Supply Voltage | 2.2 V to 3.6 V - supports single-supply operation across Li-ion battery discharge profiles (2.7–3.6 V nominal) |
| Standby Current | 1 µA typical / 4 µA max - enables multi-year battery life in always-on portable systems |
| Active Current | 1.3 mA typical at 1 MHz - balances speed and power for burst-mode data logging and buffer applications |
| Data Retention Voltage | 1.5 V minimum - maintains stored contents during brown-out or sleep-mode VCC scaling |
| Package Type | 32-pin STSOP - compact footprint (11.8 × 10.0 mm) with 0.5 mm pitch, optimized for space-constrained PCBs |
Pinout & Package
Package: 32-pin Shrunk Thin Small Outline Package (STSOP), 0.5 mm lead pitch, body size 11.8 mm × 10.0 mm, JEDEC MO-215 compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A16 | Address inputs | 17-bit address bus supporting full 128K-word addressing; TTL/CMOS compatible |
| I/O0–I/O7 | Bi-directional data bus | 8-bit parallel interface; high-impedance state asserted during deselect, write, or OE HIGH |
| CE1, CE2 | Dual chip enable inputs | Logical AND function: device selected only when CE1 = LOW and CE2 = HIGH; enables daisy-chained memory expansion |
| OE | Output enable | Controls output drivers independently of CE; allows read-data gating without toggling chip select |
| WE | Write enable | Active-LOW signal initiating write cycle; timing-critical for setup/hold compliance with address/data |
| VCC, GND | Power supply terminals | Single 2.2–3.6 V supply; decoupling required within 10 mm of VCC/GND pins per datasheet layout guidelines |
| NC | No-connect | Pin 26 (A15) is NC in STSOP variant - must be left unconnected; not bonded on die |
Key Features
| Feature | Design Value |
|---|---|
| MoBL® Ultra-Low Power Architecture | Reduces standby current to 1 µA typical - extends battery runtime in intermittent-sensing applications |
| Automatic Power-Down Mode | Enters sub-µA retention state when CE1 HIGH or CE2 LOW - eliminates need for external power-gating logic |
| Dual Chip Enable (CE1/CE2) | Enables seamless memory bank selection and hierarchical decoding without external glue logic |
| 1.5 V Data Retention | Maintains memory contents during deep-sleep or backup-battery operation - critical for RTC and configuration storage |

Equivalent & Alternatives
The following parts are listed as comparable options for similar SRAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IS62WV1288BLL-45NLI | 45 ns access, same 128K × 8, but 2.7–3.6 V only; higher ISB (5 µA typ); TSOP-32 only | Lacks 2.2 V support - unsuitable for deep-discharge battery systems below 2.7 V | Select when system VCC is regulated ≥2.7 V and legacy TSOP footprint is required |
| AS6C1008-45TIN | 45 ns, 2.7–3.6 V, 32-pin SOIC; no CE2 pin - uses single CE; ISB = 2 µA typ | Simpler enable logic but no hierarchical chip-select capability for multi-bank designs | Choose for cost-sensitive industrial controls where board space permits SOIC and expansion is not needed |
Compared with IS62WV1288BLL-45NLI and AS6C1008-45TIN, the CY62128EV30LL-45SXI uniquely supports 2.2 V operation and dual CE architecture - making it the only option for ultra-low-voltage portable systems requiring scalable memory mapping.

FAQ
What is the minimum VCC required to retain data in CY62128EV30LL-45SXI?
The device guarantees data retention down to VCC = 1.5 V, as specified in the Data Retention Characteristics table (page 6 of Rev. *N datasheet). At this voltage, ICCDR is rated ≤ 3 µA. Retention is maintained without clock or address activity, provided CE1 is HIGH or CE2 is LOW to enter retention mode.
Can CY62128EV30LL-45SXI operate with only CE1 used and CE2 tied to VCC?
Yes - CE2 may be permanently tied to VCC (VIH), enabling selection solely via CE1 LOW. This configuration reduces control lines but forfeits the hierarchical enable capability. Ensure CE2 meets VIH specification (≥2.2 V at VCC = 2.2 V) and that noise margins are verified per AC switching conditions.
Is the NC pin (Pin 26) in the STSOP package safe to connect to ground or leave floating?
Pin 26 is designated NC (no-connect) and is not bonded internally. It must remain unconnected - neither grounded nor tied to any signal. Connecting it risks internal shorting or undefined behavior, as confirmed in the Pin Configuration section (Figure 1, page 3) and Product Portfolio table (page 3).
How does the automatic power-down feature reduce power versus traditional SRAMs?
When CE1 is HIGH or CE2 is LOW, the device disables internal arrays and drivers, drawing only 1 µA typical (vs. ~10–50 µA in comparable SRAMs). This >99% reduction eliminates external power switches and simplifies PCB layout - a core advantage of the MoBL® architecture for battery longevity.
