Product details
Overview
CY7C1019CV33-10ZXI from Cypress Semiconductor is a 1 Mbit (128K × 8) high-speed CMOS static RAM with 10 ns access time, 3.3 V supply, industrial temperature range (–40°C to +85°C), and Pb-free 32-pin TSOP II package. It supports automatic power-down when deselected and features center power/ground pinout for noise reduction in embedded memory subsystems.
For engineers reviewing the CY7C1019CV33-10ZXI datasheet, CY7C1019CV33-10ZXI pinout, CY7C1019CV33-10ZXI application, or CY7C1019CV33-10ZXI equivalent, key selection criteria include tAA = 10 ns read timing, ISB2 = 5 mA standby current, CE/OE/WE control logic compatibility, and TSOP II footprint suitability for space-constrained industrial controllers.
Technical Context
The CY7C1019CV33-10ZXI implements a fully asynchronous SRAM architecture with tristate I/O drivers and dual enable control (CE and OE). Its address decoding supports 17-bit addressing (A0–A16) for 131,072 locations, and write operations require simultaneous CE LOW and WE LOW with data latched on the falling edge of WE.
Power management is handled via automatic CE-controlled power-down: ISB1 = 15 mA (TTL inputs) and ISB2 = 5 mA (CMOS inputs) at maximum VCC, with tPD = 10 ns transition delay. Input/output voltage thresholds comply with 3.3 V CMOS logic (VIH ≥ 2.0 V, VIL ≤ 0.8 V), and output drive strength meets IOH = –4.0 mA / IOL = 8.0 mA specifications.

Equivalent & Alternatives
The following parts are listed as comparable options for similar SRAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ISSI IS61LV102416L-10MLI | 1 Mbit (64K × 16), 10 ns, 3.3 V, 48-pin TSOP I - wider data bus, different pinout | Requires PCB redesign due to 16-bit bus and incompatible address/control layout | Select only if 16-bit data path and higher density per access are required |
| Cypress CY7C1019DV33-10ZXC | Same 128K × 8 organization, 10 ns, 3.3 V, but Pb-free 48-ball VFBGA package | Higher board density but requires BGA rework capability and tighter layout tolerances | Choose for space-constrained designs where TSOP II height or routing congestion is prohibitive |
Compared with IS61LV102416L-10MLI and CY7C1019DV33-10ZXC, the CY7C1019CV33-10ZXI offers direct TSOP II drop-in compatibility with legacy CY7C1019BV33 layouts, minimal signal integrity risk due to lower pin count, and guaranteed industrial temperature performance without derating.

FAQ
Is CY7C1019CV33-10ZXI compatible with CY7C1019BV33 in existing PCB layouts?
Yes - CY7C1019CV33-10ZXI is pin- and function-compatible with CY7C1019BV33, sharing identical 32-pin TSOP II footprint, address/data/control pin assignments, and timing behavior. No PCB modification is required for drop-in replacement, including identical VCC/VSS pin locations and center power/ground configuration.
What is the minimum VCC required to retain data during power loss?
Data retention is guaranteed down to 2.0 V per the datasheet, meaning stored contents remain valid when VCC drops to 2.0 V - enabling use with backup capacitors or battery switchover circuits that maintain voltage above this threshold during main supply interruption.
Does CY7C1019CV33-10ZXI support true static operation without refresh?
Yes - as a CMOS static RAM, it requires no refresh cycles. Data remains valid indefinitely as long as VCC stays within specification and the device remains powered, making it suitable for applications demanding deterministic, jitter-free memory access without hidden timing overhead.
Can OE be held LOW while performing writes to reduce cycle overhead?
No - OE must be HIGH during write operations (per Truth Table and Figure 6–8). Holding OE LOW during a write places I/O pins in output mode, risking bus contention. Correct write sequence requires CE and WE LOW, OE HIGH, and valid address/data setup before WE assertion.
