Product details
Overview
CY62136ESL-45ZSXIT from Cypress Semiconductor is a 2-Mbit (128 K × 16) CMOS static RAM with 45 ns access time, operating across dual voltage ranges (2.2–3.6 V and 4.5–5.5 V), ultra-low standby current (1 µA typical), and automatic CE-controlled power-down. It serves as a low-power, high-speed data buffer in portable embedded systems requiring battery longevity and TTL-level interfacing.
For engineers reviewing the CY62136ESL-45ZSXIT datasheet, CY62136ESL-45ZSXIT pinout, CY62136ESL-45ZSXIT application, or CY62136ESL-45ZSXIT equivalent, key selection criteria include its 44-pin TSOP II package, byte-wide I/O control (BHE/ BLE), 128K × 16 organization, MoBL® low-power architecture, and compatibility with industrial-temperature microcontrollers and DSPs.
Technical Context
The CY62136ESL-45ZSXIT implements a fully static 128K × 16 RAM array with independent byte enable (BHE/BLE) for 8-bit sub-word access and CE-driven automatic power-down that reduces ICC to ≤7 µA when deselected. Its dual-voltage support enables drop-in replacement in both 3.3 V and 5 V legacy systems.
Timing is defined by strict AC parameters: tRC = 45 ns, tAA = 45 ns, tDOE = 22 ns, and tHZOE = 18 ns. Input thresholds meet TTL logic levels (VIH = 2.2 V min at 3.3 V), making it unsuitable for pure CMOS-input processors without level translation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Size | 2 Mbit (128 K × 16) - supports 16-bit data bus architectures without external multiplexing |
| Access Time | 45 ns - enables direct interface with 22 MHz synchronous controllers or burst-mode peripherals |
| VCC Range | 2.2–3.6 V and 4.5–5.5 V - allows shared supply rails with mixed-voltage SoCs and legacy 5 V logic |
| Standby Current | 1 µA typical / 7 µA max - extends battery life in always-on sensor nodes and handheld devices |
| Active Current | 2 mA typical at 1 MHz - minimizes thermal load in compact, fanless enclosures |
| Data Retention Voltage | 1.0 V minimum - permits graceful low-power suspend-to-RAM during brownout conditions |
| Operating Temperature | –40 °C to +85 °C - qualified for industrial-grade embedded control and automotive body electronics |
Pinout & Package
Package: 44-pin Thin Small Outline Package (TSOP II), 400 mil width, lead-free (RoHS-compliant).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A16 | Address Inputs | 17-bit address bus supporting full 128K-word addressing; A16 enables 256K-byte space mapping |
| I/O0–I/O7 | Byte Low Data I/O | 8-bit bidirectional data path enabled only when BLE = LOW; high-impedance when disabled |
| I/O8–I/O15 | Byte High Data I/O | 8-bit bidirectional data path enabled only when BHE = LOW; isolated from I/O0–I/O7 for true 16-bit sub-access |
| CE | Chip Enable | Active-LOW global select; forces automatic power-down and high-Z I/O when HIGH |
| OE | Output Enable | Active-LOW read control; disables outputs (high-Z) when HIGH, independent of CE state |
| WE | Write Enable | Active-LOW write strobe; initiates write cycle only when CE = LOW and BHE/BLE active |
| BLE | Byte Low Enable | Active-LOW control for lower byte (I/O0–I/O7); enables partial writes without disturbing upper byte |
| BHE | Byte High Enable | Active-LOW control for upper byte (I/O8–I/O15); supports 8-bit peripheral coexistence on 16-bit bus |
| VCC | Power Supply | Dual-rail compatible: two dedicated VCC pins (pins 31, 32) reduce IR drop in high-speed operation |
| VSS | Ground | Two ground pins (pins 35, 36) provide low-inductance return paths for I/O switching noise suppression |
Key Features
| Feature | Design Value |
|---|---|
| MoBL® Ultra-Low Power Architecture | Reduces standby current to 1 µA typical-enables multi-year battery operation in IoT edge nodes |
| Automatic CE Power-Down | Eliminates need for external sleep controllers; cuts active-to-standby transition time to 45 ns |
| TTL-Compatible Input Thresholds | VIH = 2.2 V min at 3.3 V-directly interfaces with legacy 5 V microcontrollers and FPGAs without level shifters |
| Independent Byte Enables (BHE/BLE) | Enables atomic 8-bit writes to either half of 16-bit word-critical for real-time firmware updates and DMA buffers |
| 128K × 16 Organization | Matches common 16-bit processor data buses-avoids glue logic or external demultiplexing |

Equivalent & Alternatives
The following parts are listed as comparable options for similar SRAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ISSI IS62WV12816BLL-45NLI | Same 128K × 16 organization, 45 ns speed, but single 2.7–3.6 V supply range; no 5 V support | Lacks dual-voltage flexibility; requires separate 5 V system redesign | Select when design uses only 3.3 V rails and prioritizes lower cost over legacy compatibility |
| Renesas R1LV25616AS-45SI#S0 | Identical 45 ns timing and TSOP II package, but specifies VIH = 2.0 V min (TTL-compatible), and ISB = 5 µA max | Slightly tighter standby spec; same industrial temp grade and pinout | Preferred for new designs targeting lowest possible leakage, with verified 3.3 V TTL interface compliance |
Compared with IS62WV12816BLL-45NLI and R1LV25616AS-45SI#S0, the CY62136ESL-45ZSXIT uniquely supports both 3.3 V and 5 V operation without external regulators-critical for retrofitting into mixed-voltage legacy automotive and industrial control systems.

FAQ
Is CY62136ESL-45ZSXIT compatible with 5 V microcontrollers?
Yes-it supports 4.5–5.5 V VCC operation and features TTL-compatible input thresholds (VIH = 2.2 V min at 5 V), enabling direct connection to legacy 5 V MCUs like the 8051 or PIC18F without level shifters. However, output VOH is limited to 3.4 V max at 5 V, so verify downstream VIH requirements.
What happens to I/O pins during chip deselect?
When CE is HIGH, all I/O pins (I/O0–I/O15) enter high-impedance state regardless of OE, BHE, or BLE status-preventing bus contention. This behavior is guaranteed per datasheet Section "Functional Description" and confirmed in the Truth Table (page 11).
Can CY62136ESL-45ZSXIT retain data below 2.2 V?
Yes-data retention is specified down to VCC = 1.0 V (tCDR = 0 ns, ICCDR ≤ 3 µA). This allows use in suspend-to-RAM modes during brownout, provided CE remains HIGH and address/data lines are held static, as defined in the Data Retention Waveform (Figure 3).
Does this SRAM require external refresh circuitry?
No-CY62136ESL-45ZSXIT is a fully static RAM with no refresh requirement. All memory cells retain data indefinitely while powered and selected, or during data retention mode (VCC ≥ 1.0 V, CE HIGH), eliminating refresh overhead and timing constraints.
