Product details
Overview
CY62177ESL-55ZXIT from Infineon Technologies (formerly Cypress) is a 32-Mbit MoBL® CMOS static RAM organized as 2M × 16 or 4M × 8, operating at 55 ns access time with dual voltage support (2.2–3.6 V and 4.5–5.5 V), ultra-low standby current (3 µA typ), and automatic power-down for portable battery-powered systems.
For engineers reviewing the CY62177ESL-55ZXIT datasheet, CY62177ESL-55ZXIT pinout, CY62177ESL-55ZXIT application, or CY62177ESL-55ZXIT equivalent, this SRAM delivers verified low-power operation in industrial temperature range (–40 °C to +85 °C), configurable byte-width interface, and TSOP I package compatibility for space-constrained embedded memory expansion.
Technical Context
The CY62177ESL-55ZXIT implements dual-bank byte-select architecture with independent BHE/ BLE controls enabling simultaneous high/low byte access, and supports automatic power-down when CE1 is HIGH, CE2 is LOW, or both BHE and BLE are HIGH - reducing active-to-standby transition time to ≤55 ns. Its CMOS design ensures TTL-compatible logic thresholds across both voltage ranges.
Memory organization is dynamically selectable via BYTE pin: tied to VCC for 2M × 16 mode (A0–A20 address space), or to VSS for 4M × 8 mode (A0–A21, with A21 on pin 45). Data retention is guaranteed down to 1.5 V with ICCDR ≤17 µA, supporting brown-out recovery in portable systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Capacity | 32 Mbit (2M × 16 or 4M × 8), enabling flexible data bus width selection per system architecture |
| Access Time | 55 ns max - guarantees deterministic read/write timing for real-time microcontroller interfaces |
| Voltage Range | 2.2–3.6 V and 4.5–5.5 V - supports dual-supply legacy and low-voltage modern designs without level-shifting |
| Standby Current | 3 µA typical / 25 µA max - enables multi-year battery life in always-on IoT endpoints |
| Operating Current | 4.5 mA typical at 1 MHz - balances performance and power for burst-mode applications |
| Data Retention Voltage | 1.5 V min - maintains memory state during deep sleep or supply sag without external backup |
| Temperature Range | –40 °C to +85 °C industrial grade - validated for automotive infotainment and industrial HMI use |
Pinout & Package
48-pin Thin Small Outline Package I (TSOP I), RoHS-compliant, 12 mm × 20 mm footprint, 0.5 mm pitch. Pin 1 marked by beveled corner; BYTE pin configures memory width (VCC = 2M×16, VSS = 4M×8).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A20 | Address inputs | 21-bit address bus; A21 used only in 4M×8 mode (pin 45) |
| I/O0–I/O7 | Data inputs/outputs (low byte) | Active when BLE = LOW; tri-stated when BLE = HIGH or device deselected |
| I/O8–I/O15 | Data inputs/outputs (high byte) | Active when BHE = LOW; tri-stated when BHE = HIGH or device deselected |
| CE1, CE2 | Chip enable controls | CE1 LOW + CE2 HIGH enables device; CE1 HIGH or CE2 LOW forces standby |
| OE | Output enable | LOW enables read data output; HIGH places I/O pins in high-Z state |
| WE | Write enable | LOW initiates write; must be synchronized with CE and byte enables |
| BHE, BLE | Byte high/low enable | Independent control of upper/lower 8-bit data lanes; both HIGH disables all I/O |
| BYTE | Memory width configuration | Tied to VCC for 2M×16 (A0–A20); tied to VSS for 4M×8 (A0–A21, pin 45 = A21) |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-density, low-power SRAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ISSI IS62WV204816BLL-55NLI | Same 2M×16 organization, 55 ns speed, but single 2.7–3.6 V supply; no 4.5–5.5 V support | Limited to 3.3 V systems; lacks dual-voltage flexibility for mixed-rail designs | Select when only 3.3 V operation is required and cost sensitivity outweighs voltage versatility |
| Renesas R1LV25616AS-5SI#S0 | 256 K × 16 (4 Mbit), not 32 Mbit; faster 45 ns access but lower density and no automatic power-down | Insufficient capacity for full-frame buffering; requires external power management circuitry | Choose only for legacy 4 Mbit upgrades where board space prevents larger SRAM placement |
Compared with IS62WV204816BLL-55NLI and R1LV25616AS-5SI#S0, the CY62177ESL-55ZXIT uniquely combines 32 Mbit density, dual-voltage operation, sub-µA standby, and hardware-configurable bus width - making it the sole option for next-generation portable and industrial systems requiring scalable, low-power memory expansion.

FAQ
What is the function of the BYTE pin on CY62177ESL-55ZXIT?
The BYTE pin selects memory organization: tied to VCC configures the device as 2M × 16 (A0–A20), while tied to VSS enables 4M × 8 mode (A0–A21, with A21 on pin 45). In 4M × 8 mode, BHE, BLE, and I/O8–I/O14 are unused. This hardware-selectable feature eliminates need for external configuration logic.
Does CY62177ESL-55ZXIT support true 5 V operation?
Yes - the device is fully specified for 4.5 V to 5.5 V operation, including VOH ≥2.4 V at IOH = –1.0 mA and VOL ≤0.4 V at IOL = 2.1 mA. It meets TTL-compatible thresholds in this range and supports mixed-voltage systems alongside legacy 5 V peripherals without level shifters.
How does automatic power-down reduce power consumption?
When CE1 is HIGH, CE2 is LOW, or both BHE and BLE are HIGH, the device enters automatic power-down mode, reducing ICC to ≤25 µA. This 99% reduction versus active current occurs without software intervention and is triggered by stable address/bus conditions - ideal for intermittent data logging.
Can CY62177ESL-55ZXIT retain data below 2.2 V?
Yes - data retention is guaranteed down to VDR = 1.5 V, with ICCDR ≤17 µA. At this voltage, the SRAM maintains stored contents during brown-out or battery sag, enabling safe state preservation before controlled shutdown in portable equipment.
