Product details
Overview
CY62128VLL-70ZC from Cypress Semiconductor is a 128 K × 8 (131,072 × 8) CMOS static RAM with 70 ns access time, 2.7–3.6 V supply range, TTL-compatible I/O, and dual chip enable (CE1 active-low, CE2 active-high) for flexible memory expansion in embedded controllers and industrial data loggers.
For engineers reviewing the CY62128VLL-70ZC datasheet, CY62128VLL-70ZC pinout, CY62128VLL-70ZC application, or CY62128VLL-70ZC equivalent, key selection criteria include standby current (≤100 µA), automatic CE power-down behavior, 32-pin TSOP-I package compatibility, and read/write timing margins under industrial temperature (–40°C to +85°C).
Technical Context
The CY62128VLL-70ZC implements a 512 × 256 × 8 memory array with separate row/column decoders and sense amplifiers. Its dual CE architecture enables hierarchical memory mapping-CE1 and CE2 must be asserted (CE1 = LOW, CE2 = HIGH) to select the device, while OE and WE control read/write directionality and output state.
It features three-state I/O drivers with guaranteed high-impedance during deselection (CE1 HIGH or CE2 LOW), write cycles (WE LOW), or OE HIGH. Power-down is fully automatic: ISB2 ≤100 µA at VCC = 3.6 V and TA = 85°C when CE exceeds VCC – 0.3 V and inputs are clamped to rail.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Organization | 131,072 words × 8 bits - supports byte-wide data bus interfacing without external multiplexing |
| Access Time | 70 ns max - ensures reliable operation with microcontrollers running ≤14 MHz bus clocks |
| VCC Range | 2.7 V to 3.6 V - compatible with 3.3 V systems and tolerant of ±5% supply variation |
| Standby Current (ISB2) | ≤100 µA at VCC = 3.6 V, TA = 85°C - enables low-power retention in battery-backed applications |
| Input/Output Compatibility | TTL-level thresholds (VIH = 2.0 V min, VOL = 0.4 V max) - interoperable with legacy 5 V logic via level-shifting or direct interface at 3.3 V |
| Operating Temperature | –40°C to +85°C - qualified for industrial-grade deployment in motor drives and PLCs |
| Capacitance | CIN ≤6 pF, COUT ≤8 pF - minimizes signal integrity impact on high-speed address/data buses |
Pinout & Package
Package: 32-lead TSOP-I (Type 1), 10.16 mm × 13.10 mm body, 0.5 mm pitch, JEDEC MO-141AC compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A16 | Address Inputs | 17-bit address bus supporting full 128K word decoding; no internal latching |
| I/O0–I/O7 | Bidirectional Data Bus | True three-state I/O pins; high-impedance when CE1 HIGH, CE2 LOW, OE HIGH, or during write |
| CE1 | Active-Low Chip Enable | Primary selection signal; device unselected if HIGH, regardless of CE2 state |
| CE2 | Active-High Chip Enable | Secondary enable; must be HIGH with CE1 LOW for valid access; enables bank decoding |
| OE | Active-Low Output Enable | Controls output drivers only; does not affect internal memory state or power mode |
| WE | Active-Low Write Enable | Initiates write cycle when CE1 LOW and CE2 HIGH; data latched on WE rising edge |
| VCC | Power Supply | 2.7–3.6 V core supply; decoupling capacitor required within 10 mm of pin |
| GND | Ground Reference | Digital ground plane connection; shared with I/O and control signals |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar SRAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ISSI IS62WV1288BLL-70NLI | Same 128K×8 organization, 70 ns speed, but uses single active-low CE and operates down to 2.2 V | Lacks dual CE architecture; requires external gating for multi-bank designs | Select when board space is constrained and CE logic simplification outweighs expansion flexibility |
| Renesas R1LV12816AS-70L | 128K×8, 70 ns, but rated only for commercial temp (0°C to +70°C); lower ISB2 (10 µA typical) | Not qualified for industrial environments; unsuitable for outdoor or motor-control enclosures | Choose only for cost-sensitive consumer electronics where ambient stays below 70°C |
Compared with IS62WV1288BLL-70NLI and R1LV12816AS-70L, the CY62128VLL-70ZC uniquely delivers dual CE support, industrial temperature rating, and guaranteed 100 µA max ISB2-making it the sole choice for expandable, ruggedized SRAM subsystems.

Manufacturer
Cypress Semiconductor (now part of Infineon Technologies) is a fabless semiconductor company specializing in high-reliability memory, PSoC, and USB/USB-C solutions for industrial and automotive markets.

FAQ
What is the minimum VCC required to retain data in CY62128VLL-70ZC?
Data retention is guaranteed down to 1.6 V VCC, as specified in the Data Retention Characteristics table. At this voltage, ICCDR remains ≤10 µA under industrial conditions (TA = 85°C), enabling use with supercapacitor or coin-cell backup circuits that decay below 2.7 V nominal operation.
Can CY62128VLL-70ZC be used with a 5 V microcontroller without level shifters?
No. Although input thresholds meet TTL levels (VIH ≥2.0 V), the absolute maximum VCC is 4.6 V and IOH/IOL drive strength is specified only for 2.7–3.6 V operation. Direct 5 V interface risks exceeding VIH max (VCC + 0.5 V) and may cause latch-up or accelerated wear.
How does the dual CE architecture improve memory expansion compared to single-CE SRAMs?
CE1 (active-low) and CE2 (active-high) allow hierarchical decoding: CE2 can serve as a bank-select signal across multiple devices, while CE1 acts as individual chip select. This eliminates need for external logic gates in 256K+ configurations and reduces address decode propagation delay versus OR-gated CE schemes.
Is the 70 ns access time guaranteed over the full industrial temperature range?
Yes. The 70 ns tRC and tAA specifications are validated across –40°C to +85°C at VCC = 2.7 V to 3.6 V. Electrical Characteristics tables explicitly list "Ind'l" rows with corresponding min/max values, and switching waveforms are tested under worst-case corner conditions per JEDEC JESD22-A108.
