Product details
Overview
CY7C1019CV33-12ZXCT from Cypress Semiconductor is a 1 Mbit (128K × 8) CMOS static RAM with 3.3 V supply, 12 ns access time, industrial temperature range (–40°C to +85°C), and Pb-free 32-pin TSOP II packaging. It serves as a high-speed, low-power data buffer or working memory in microcontroller-based control systems, real-time instrumentation, and legacy bus-interface modules.
For engineers reviewing the CY7C1019CV33-12ZXCT datasheet, CY7C1019CV33-12ZXCT pinout, CY7C1019CV33-12ZXCT application, or CY7C1019CV33-12ZXCT equivalent, key selection criteria include tAA = 12 ns read timing, automatic CE-controlled power-down (ISB2 = 5 mA), tristate I/O compatibility with 8-bit parallel buses, and pin/function equivalence with CY7C1019BV33 for drop-in replacement in existing designs.
Technical Context
This SRAM implements a synchronous, non-volatile-retentive memory array with full address decoding (A0–A16), active-low chip enable (CE), output enable (OE), and write enable (WE) controls. Its center power/ground pinout reduces noise coupling, and automatic power-down activates when CE is HIGH, reducing ICC to 5 mA at standby.
The device supports three read modes (CE/OE-controlled, OE-only, and CE-only) and two write modes (CE-controlled and WE-controlled), with guaranteed timing margins across all transitions - including tHZOE = 6 ns, tLZCE = 3 ns, and tPD = 12 ns - ensuring reliable interfacing with FPGA, ASIC, and MCU parallel memory controllers.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Organization | 128K × 8 bits (1,048,576 total bits); supports byte-wide data transfers without external demultiplexing. |
| Access Time (tAA) | 12 ns max; enables direct interface with 80 MHz bus clocks without wait states in FPGA or microcontroller systems. |
| VCC Supply | 3.3 V ± 10%; compatible with standard LVTTL and LVCMOS I/O domains without level-shifting. |
| Standby Current (ISB2) | 5 mA max at VCC = 3.6 V, CE HIGH; critical for low-power hold mode in battery-backed or energy-constrained applications. |
| Operating Temperature | –40°C to +85°C (Industrial grade); validated for use in motor control enclosures and industrial PLC backplanes. |
| I/O Drive Strength | IOH = –4.0 mA / IOL = 8.0 mA; sufficient to drive 10 cm of 50 Ω PCB trace or fan-out to 10 LVTTL loads. |
| Input/Output Capacitance | CIN/COUT = 8 pF max; minimizes signal integrity degradation on high-speed parallel address/data buses. |
Pinout & Package
Package: 32-pin TSOP II (0.400-inch width), Pb-free, JEDEC MO-141AC compliant. Body dimensions: 11.8 mm × 13.8 mm × 1.2 mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A16 | Address Inputs | 17-bit address bus; selects one of 131,072 locations; A0 = LSB, A16 = MSB. |
| I/O0–I/O7 | Bidirectional Data Bus | 8-bit tristate I/O; high-impedance during CE HIGH, OE HIGH, or WE LOW. |
| CE | Chip Enable (active LOW) | Primary selection signal; enables memory access and disables internal circuitry when HIGH to enter ISB2 mode. |
| OE | Output Enable (active LOW) | Controls data output drivers only; does not affect internal state or power consumption. |
| WE | Write Enable (active LOW) | Initiates write cycle when CE is LOW; latches data on I/O pins into addressed location. |
| VCC | Power Supply | 3.3 V core and I/O supply; two dedicated VCC pins (pins 16 and 24) reduce IR drop and switching noise. |
| VSS | Ground | Two ground pins (pins 15 and 31) provide low-inductance return paths for address, data, and control signals. |
Key Features
| Feature | Design Value |
|---|---|
| Automatic Power Down | CE HIGH triggers ISB2 ≤ 5 mA standby current without external logic or sleep commands. |
| Center Power/Ground Pinout | VCC and VSS placed centrally (pins 16, 24, 15, 31) suppress simultaneous switching noise on wide parallel buses. |
| Pb-Free Packaging | RoHS-compliant TSOP II (JEDEC 95-3A) with matte tin lead finish; qualified per J-STD-020D reflow profile. |
| Pin-Compatible Upgrade | Direct replacement for CY7C1019BV33; identical pinout, timing, and logic behavior - no PCB redesign required. |
| Easy Memory Expansion | CE and OE allow seamless stacking of multiple devices using address decoding or bank-select logic. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar SRAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ISSI IS61LV102416L-12MLI | 1 Mbit × 16 organization, 32-pin SOJ, 12 ns access, 3.3 V; wider data bus but different pinout and address mapping. | Requires PCB layout change and address bus remapping; suited for 16-bit systems needing higher throughput. | Select only if system uses 16-bit data path and requires single-cycle burst reads. |
| Cypress CY7C1019DV33-12ZXC | Same 128K × 8 organization, 3.3 V, 12 ns, TSOP II; newer revision with enhanced ESD robustness (HBM > 4 kV) and tighter tHZOE spec (5 ns). | Drop-in compatible; preferred for new designs requiring extended lifecycle support and improved reliability. | Choose for new production builds where long-term availability and higher ESD immunity are prioritized. |
Compared with IS61LV102416L-12MLI, CY7C1019CV33-12ZXCT offers byte-level compatibility and proven interoperability with legacy 8-bit controllers; versus CY7C1019DV33-12ZXC, it trades minor ESD margin for established qualification history in deployed industrial systems.

FAQ
Is CY7C1019CV33-12ZXCT compatible with 5 V tolerant systems?
No. This device operates strictly at 3.3 V ± 10% and is not 5 V tolerant. Input voltages must remain within –0.3 V to VCC + 0.3 V (max 3.63 V). Interfacing with 5 V logic requires level translation on all address, data, and control lines to avoid damage or undefined behavior.
Does CY7C1019CV33-12ZXCT retain data at reduced VCC?
Yes. The device guarantees data retention down to 2.0 V VCC, enabling use in brownout scenarios or battery-backed hold modes. Retention is specified over the full industrial temperature range and does not require continuous clocking or refresh cycles.
What is the meaning of "ZXC" in the part number CY7C1019CV33-12ZXCT?
"ZXC" denotes Pb-free 32-pin TSOP II packaging with industrial temperature grade (–40°C to +85°C). The trailing "T" indicates tape-and-reel packaging (1,000 units per reel), per Cypress ordering conventions documented in datasheet rev. *G.
Can CY7C1019CV33-12ZXCT be used in place of CY7C1019BV33?
Yes. It is pin- and function-compatible with CY7C1019BV33, sharing identical pinout, timing parameters, and logic behavior. No hardware or firmware changes are needed, though users should verify voltage tolerance alignment (both are 3.3 V devices) and confirm board-level decoupling meets updated current transient requirements.
