Product details

Overview

CY7C1011CV33-12AXI from Infineon Technologies is a 1-Mbit (64K × 16) asynchronous static RAM (SRAM) with 3.3 V supply, 12 ns access time, and industrial temperature range (–40°C to +85°C). It features TTL-compatible inputs/outputs, low-power CMOS design, and operates in byte-wide or word-wide configurations for embedded control and data buffering.

For engineers reviewing the CY7C1011CV33-12AXI datasheet, CY7C1011CV33-12AXI pinout, CY7C1011CV33-12AXI application, or CY7C1011CV33-12AXI equivalent, key selection criteria include access timing consistency, industrial-grade thermal stability, parallel bus interface compatibility, and direct replacement capability in legacy SRAM-based memory subsystems.

Technical Context

This SRAM implements a fully static core with no refresh required, supporting true random access across all addresses. Its architecture includes on-chip address latching, bidirectional data I/O with three-state control, and independent chip enable (CE1, CE2) and output enable (OE) logic for flexible memory mapping.

The device uses a standard parallel interface with separate address, data, and control buses. It supports both high- and low-byte enables (UB/LB) for 16-bit data bus partitioning, enabling byte-level read/write operations without external glue logic in microcontroller or FPGA-based systems.

Key Specifications

Memory Density	1 Mbit (64K × 16), providing 65,536 words of 16-bit data storage
Supply Voltage	3.3 V ± 0.3 V, compatible with modern low-voltage logic families and reducing system power consumption
Access Time	12 ns max at V_CC = 3.3 V, ensuring deterministic timing for real-time control loops and burst data transfers
Operating Temperature	–40°C to +85°C, validated for industrial environments without derating
Power Dissipation	120 mW typical active current (I_CC = 36 mA), enabling use in thermally constrained enclosures

CE1, CE2	Chip Enables	Active-low dual CE inputs allow hierarchical memory decoding; both must be asserted for device activation
OE	Output Enable	Controls data bus direction: low enables read output, high places DQ pins in high-impedance state
WE	Write Enable	Active-low signal initiating write cycle; synchronous with address and data setup/hold timing
UB, LB	Byte Enables	Independent upper/lower byte controls for 16-bit bus partitioning; support 8-bit microprocessor interfacing

Equivalent & Alternatives

The following parts are listed as comparable options for similar asynchronous SRAM applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
IS61LV102416AL-12TLI	12 ns access, 3.3 V, but uses 48-pin TSOP I package and lacks UB/LB pins	Requires PCB redesign due to different pin count and missing byte-enable functionality	Select only if board layout allows 48-pin footprint and byte-level writes are not required
AS6C1008-12ZIN	12 ns access, 3.3 V, 44-pin TSOP II, but rated only for commercial temperature (0°C to +70°C)	Not qualified for industrial or automotive thermal environments	Acceptable only for indoor, climate-controlled applications with no thermal stress

Compared with IS61LV102416AL-12TLI and AS6C1008-12ZIN, CY7C1011CV33-12AXI uniquely combines industrial temperature rating, byte-enable support, and 44-pin TSOP II compatibility-making it the only drop-in replacement for legacy Cypress-based designs requiring robust thermal performance and flexible bus interfacing.

FAQ

What is the maximum clock frequency supported by CY7C1011CV33-12AXI?

CY7C1011CV33-12AXI is an asynchronous SRAM and does not use a clock signal. Its operation is governed by access time (12 ns) and timing parameters including t_AA, t_OE, and t_CO. System timing is determined by the controlling microcontroller or FPGA's bus cycle duration-not by an internal clock.

Does CY7C1011CV33-12AXI support battery backup operation?

Yes. With standby current as low as 1 µA at 3.3 V and no refresh requirement, CY7C1011CV33-12AXI maintains data integrity during main power loss when backed by a coin-cell or supercapacitor. The device retains data as long as V_CC remains above V_CC(min) = 2.0 V, per datasheet specification.

Can CY7C1011CV33-12AXI be used with 5 V microcontrollers?

No. CY7C1011CV33-12AXI is strictly a 3.3 V device. Its input voltage tolerance is limited to V_IH = 2.0 V min and V_IL = 0.8 V max-compatible only with 3.3 V logic families. Direct connection to 5 V I/O violates absolute maximum ratings and risks permanent damage.

Is there a lead-free and RoHS-compliant version of this part?

Yes. CY7C1011CV33-12AXI is manufactured in a lead-free, RoHS-compliant process. The "-12AXI" suffix denotes industrial temperature grade and Pb-free TSOP II packaging, verified per JEDEC J-STD-020 moisture sensitivity level 3 and IPC/JEDEC J-STD-033 handling requirements.
