Product details
Overview
CY62127DV30L-55ZSXET from Cypress Semiconductor is a 1-Mb (64K × 16) low-voltage CMOS static RAM with 55 ns access time, 2.2–3.6 V supply range, and industrial temperature rating (–40°C to +85°C). It features automatic CE power-down, ultra-low standby current (1.5 µA typ), and byte-wide I/O control via BHE/ BLE for embedded memory expansion in portable and battery-powered systems.
For engineers reviewing the CY62127DV30L-55ZSXET datasheet, CY62127DV30L-55ZSXET pinout, CY62127DV30L-55ZSXET application, or CY62127DV30L-55ZSXET equivalent, this page delivers verified timing parameters, FBGA package mapping, byte-enable logic behavior, and MoBL®-optimized power metrics critical for portable SoC memory subsystem design.
Technical Context
The CY62127DV30L-55ZSXET implements a 64K × 16 asynchronous SRAM architecture with independent high- and low-byte enables (BHE/BLE), enabling partial-word writes without read-modify-write cycles. Its CE-controlled automatic power-down reduces ICC by >90% when addresses are static.
It supports true dual-byte operation: simultaneous or independent access to I/O0–I/O7 (low byte) and I/O8–I/O15 (high byte), with output enable (OE) and write enable (WE) fully decoupled from CE for flexible bus timing control in multi-master environments.
Key Specifications

|---|---|
| Memory Organization | 64K words × 16 bits - provides 128 KB of fast, non-refreshed storage for firmware buffers or real-time data logging |
| Access Time | 55 ns - ensures compatibility with 18 MHz system buses without wait states |
| Supply Voltage Range | 2.2 V to 3.6 V - supports direct interface with 2.5 V and 3.3 V logic domains and Li-ion battery discharge profiles |
| Active Current (f = 1 MHz) | 0.85 mA typ - enables multi-hour operation in always-on sensor nodes powered by coin cells |
| Standby Current (ISB2) | 1.5 µA typ - achieves >99% power reduction during sleep modes in portable medical devices |
| Operating Temperature | –40°C to +85°C - qualified for industrial-grade deployment in factory automation controllers |

Pinout & Package
Package: 48-ball Fine-Pitch Ball Grid Array (FBGA), RoHS-compliant, 6 mm × 8 mm footprint, 0.8 mm ball pitch. Pin #E3 is DNU (do not use); NC pins are unconnected to die.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A15 | Address Inputs | 16-bit address bus supporting full 64K-word decoding; compatible with standard microcontroller address lines |

| I/O8–I/O15 | Data Bus (High Byte) | Bi-directional 8-bit data path enabled only when BHE = LOW; operates independently of low-byte activity |
| CE | Chip Enable | Active-LOW global select; triggers automatic power-down when HIGH and no address toggling occurs |
| OE | Output Enable | Active-LOW read control; places I/Os in high-Z when HIGH, regardless of CE state |
| WE | Write Enable | Active-LOW write strobe; initiates write cycle only when CE and corresponding BHE/BLE are also LOW |
| BLE | Byte Low Enable | Active-LOW control for I/O0–I/O7; allows partial-word writes without disturbing upper byte contents |
| BHE | Byte High Enable | Active-LOW control for I/O8–I/O15; enables concurrent or exclusive high-byte access |

Equivalent & Alternatives
The following parts are listed as comparable options for similar SRAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ISSI IS62WV51216BLL-55NLI | Same 512K × 16 organization, 55 ns speed, but 2.5–3.6 V supply range; lacks automatic CE power-down | Requires external power management for low-power sleep; suitable where voltage rails are stable at 2.5 V+ | Select if board already uses ISSI's footprint and 2.5 V regulation is fixed |
| ON Semiconductor NVSRAM N25S80-55G | Non-volatile SRAM with integrated EEPROM backup; 55 ns access but higher standby current (10 µA typ) | Eliminates external backup battery or capacitor for data retention; adds 10 ms write-to-EEPROM latency on power loss | Select when data persistence across power failures is mandatory and 10 µA standby is acceptable |
Compared with IS62WV51216BLL-55NLI and N25S80-55G, the CY62127DV30L-55ZSXET uniquely combines MoBL®-grade ultra-low standby current (1.5 µA), automatic CE-triggered power-down, and full 2.2 V minimum operation - making it optimal for energy-constrained, wide-input-voltage portable designs where volatility is acceptable.

FAQ
What is the maximum clock frequency supported for burst reads?
This is an asynchronous SRAM - it has no internal clock and does not support burst reads. Data access is controlled solely by CE, OE, and WE timing. The 55 ns access time defines the minimum interval between address setup and valid data output, allowing reliable interfacing with microcontrollers running up to ~18 MHz without wait states.
Can BHE and BLE be used simultaneously for full 16-bit access?
Yes - asserting both BHE and BLE LOW enables concurrent read or write of all 16 data bits (I/O0–I/O15). The truth table confirms "Read All bits" and "Data In" modes when both byte enables are active, with no timing penalty versus single-byte operation.
Is the 48-ball FBGA pinout compatible with CY62127BV-series TSOP packages?
No - the FBGA (CY62127DV30L-55ZSXET) and TSOP II (e.g., CY62127BV30L-55ZXI) have fundamentally different pinouts and ball/lead assignments. Though functionally pin-compatible in logic role, physical layout, signal routing, and thermal pad requirements differ significantly; PCB redesign is required for migration.
Does the device retain data during VCC brownout conditions?
Yes - data retention is guaranteed down to VCC = 1.5 V (VDR), with typical retention current of 4 µA at that voltage. The device enters data retention mode automatically when VCC drops below operational thresholds, provided CE remains HIGH and address lines are stable.
